Best ExtraHop RevealX Alternatives and Competitors

If you run or have evaluated ExtraHop RevealX and need a replacement shortlist you can defend, this page is built for that decision. It profiles ten NDR vendors that can substitute for RevealX as the primary network-layer detection control, selected by a published four-test inclusion rule: independent analyst evaluation, cross-checked 2026 Magic Quadrant confirmation, product substitutability, and corporate status verified on a stated date. The full rule, and the two candidates it excluded, appear before the list.

Most pages ranking for ExtraHop alternatives and ExtraHop competitors are generated by revenue-band or keyword adjacency, which is how a payroll platform ends up peer-matched to a security vendor. This one labels every capability statement as the vendor's own claim and publishes the licensing units, ownership records, and analyst placements that actually decide these evaluations. If you need a category primer first, start with network detection and response, the discipline of detecting attacker behavior from network traffic rather than endpoint agents.

Vendor status verified 2026-08-12

Why consider an ExtraHop alternative?

Buyers rarely leave an NDR platform over feature counts. The substitution triggers in the research are licensing units, alert load, architecture portability, and corporate uncertainty.

What ExtraHop RevealX is, and the naming history

ExtraHop is an NDR vendor founded in 2007, and RevealX is its current product name, trademarked. The legacy form is Reveal(x), with a parenthesized x, and third parties still use both spellings; the earliest clean "RevealX" usage the research could date on ExtraHop's own blog is 2025-02-11, and no dedicated rebrand announcement was found, which is recorded as not found rather than proof none exists. Per ExtraHop's own FAQ, the tiers are RevealX 360 (SaaS) and RevealX Enterprise (self-managed). Anyone asking what is ExtraHop in 2026 should anchor on that current naming.

Detection capabilities and architecture provenance

Two of the four questions Google surfaces for this query are answered by no ranking page. Both are answered here from primary materials.

Does ExtraHop use AI? Yes, and the mechanism is documented. Per ExtraHop's own materials (observed 2026-08-11), raw packets become structured records, move to ExtraHop Cloud Services, and train machine learning models built on "over 5,000 metrics" and "more than 4,600 features". Its 2026 positioning is explicitly agentic: the Agentic SOC Alliance launched 2026-07-22 with 15 founding members on a "Context, Harness, Model" architecture. One caveat: a rival's comparison page asserts ExtraHop relies primarily on unsupervised learning with little context or explainability. That is a competitor claim, and it is unverified.

Does ExtraHop use Zeek? No, and the useful answer has three parts. ExtraHop's parsing is proprietary: a real-time stream processor performing "line-rate decryption (optional), multi-protocol decoding, and full-stream reassembly" at "sustained rates of 100 Gbps" across 90+ protocols (vendor materials, observed 2026-08-11). Zeek belongs to Corelight, co-founded in 2013 by Zeek creator Vern Paxson with Robin Sommer and Seth Hall. And ExtraHop's IDS add-on does accept custom rules "formatted according to Suricata guidelines", subject to a 10,000-rule cap (vendor docs, version 9.6). The one-liner: ExtraHop does not use Zeek, its pipeline is proprietary, and its IDS module ingests Suricata-format rules. That bounding comes from pages fetched in the research run, not the full codebase.

Architecture provenance for the two platforms most often compared on parsing lineage, from each vendor's own published materials.

Visibility, integrations, and alert prioritization

ExtraHop integrations are heavily searched but thinly documented: ExtraHop publishes purchase channels (direct, channel partners, AWS Marketplace) and an integrations surface, but the research holds no verified inventory, so a complete list is Not available in research. One relationship runs unusually deep: the CrowdStrike partnership spans Falcon LogScale (2024) and Falcon Next-Gen SIEM (2024) integrations, expansions in 2025, and shared Agentic SOC Alliance membership (2026), which matters to buyers standardized on that endpoint stack. On alert prioritization, the research holds no neutral measurement of ExtraHop alert quality; every comparative alert-fidelity figure in circulation is a vendor claim. Neutral measurement: Not available in research. Test network visibility coverage and network traffic analysis depth in your own environment instead.

Licensing and what actually drives cost

Nobody on this SERP explains ExtraHop pricing, so here is the model, without a price, because no list price exists anywhere in the research. RevealX 360 is priced on Discovered Devices, daily record ingest capacity, and record lookback period; RevealX Enterprise on Discovered Devices alone (ExtraHop's own FAQ, re-verified 2026-08-12). Counting compounds: a device seen by multiple sensors counts toward each sensor's capacity, and reseller SKUs are asset-count banded (for example, 9,200 and 6,200 asset bands). The substitution trigger shows up verbatim in peer reviews of ExtraHop RevealX: "They changed that to an asset-based license model, and that's an absolute downside of the solution" (PeerSpot reviewer, 2026). Reviewers rate affordability "between three and seven out of ten"; the same listing shows 8.6 out of 10 from exactly 15 reviews as of August 2026, which answers the ExtraHop reviews question with its sample size attached. A dated third-party pricing verification (2026-07-08) reports both tiers as quote-only.

ExtraHop RevealX licensing basis per the vendor's own FAQ, re-verified 2026-08-12; no list price is published for any tier.

Top 10 ExtraHop alternatives and competitors for NDR and network security

No ranking listicle on this SERP publishes an inclusion rule. This page does. A vendor appears here only if it meets all four tests: evaluated in the Forrester Wave: Network Analysis and Visibility Solutions, Q4 2025, which named twelve vendors on Forrester's own blog; cross-checked against 2026 Gartner Magic Quadrant for NDR placements confirmed by the placed vendor's own announcement; substitutable for RevealX as the primary network-layer detection control; and corporate status verified 2026-08-12 with current owner and product name recorded. The result is a defensible set of network security controls, not a directory of adjacent brands.

Ten NDR alternatives to ExtraHop RevealX, with analyst status and corporate status verified on 2026-08-12; best-for entries condense each vendor's profile section below and are vendor framing except where labeled neutral.

Two candidates were excluded from the twelve-name pool. Stellar Cyber fails test one: it is not among the twelve Wave-evaluated vendors, and its only analyst placement in the research rests on a single secondary source. Lumu Technologies passes test one but carries the thinnest substitutability corroboration, appearing in no category-coherent editorial NDR list captured in the research. Wave positions are stated as fact only where self-announced by the placed vendor (Corelight, Trend Micro, and ExtraHop as Leaders); every other Wave row reads "Evaluated", because absence of a placement cell is absence of evidence, never a negative finding.

1. Vectra AI

Introduction

Vectra AI is named a Leader in the 2026 Gartner Magic Quadrant for NDR, confirmed by its own announcement (2026), and was evaluated in the Forrester Wave NAV Q4 2025. It is independent, PE and VC backed. For the direct head-to-head, see Vectra AI vs. ExtraHop.

Key capabilities

Every line here is self-reported, held to the same standard as every other vendor on this page. Vectra AI states its platform delivers "modern network observability, signal, and actions" across network, identity, and cloud, built on components it names "Security-Led Modeling", "Real-Time Streaming Engine (Jetstream)", "Metadata Signal Fabric", and "Multi-Layer Attribution". It also states "35 patents in cybersecurity AI" and "12 references in MITRE D3FEND, more than any other vendor" (brand documentation, self-reported).

Key differences between Vectra AI and ExtraHop

Both columns are vendor claims except the analyst-status row; the ExtraHop host-count figure is Vectra-asserted and unverified.

Pros and cons

The neutral datum worth more than any vendor adjective: on PeerSpot's NDR category comparison, Vectra AI's mindshare stands at 9.8%, down from 15.9% year over year, as of August 2026, on the same page and day that record ExtraHop at 5.4%, down from 8.6%. Mindshare is an engagement-derived proxy, not market share and not a ranking; this page publishes its own declining figure alongside a rival's because that is the standard it applies to everyone. Vendor-neutral cons beyond that figure: Not available in research.

Who is it best suited for?

Medium-to-large enterprises, roughly 2,500 to 25,000 employees, running hybrid estates with security teams under five analysts, EDR deployed, SIEM cost pressure, and regulatory exposure. Teams weighing investigation workload can read the Advens customer story.

2. Darktrace

Introduction

Darktrace is a Leader in the 2026 Gartner Magic Quadrant for NDR for the second consecutive year, confirmed by its own announcement (2026), and was evaluated in the Forrester Wave NAV Q4 2025. Thoma Bravo owned, acquisition completed October 2024. The product renders as Darktrace / NETWORK, and a new "Darktrace Behavioral Defense Platform" umbrella name (announced 2026-08-03) currently coexists on-site with "Darktrace ActiveAI Security Platform".

Key capabilities

The vendor states its Self-Learning AI is deployed locally and trained solely on the customer's own data; that it analyzes both encrypted and decrypted traffic; that Cyber AI Analyst runs automated end-to-end investigations; that response actions include "isolating infected devices, forcing a user to reauthenticate, or blocking suspicious IP addresses" (2026); and that detection is signature-independent with optional STIX/TAXII ingestion. Neutral coverage of its October 2025 network expansion corroborates the category.

Key differences between Darktrace and ExtraHop

All rows are the respective vendors' own claims; the two 2026 Magic Quadrant Leader placements are the only facts in this entry.

Pros and cons

On PeerSpot's Darktrace listing: 4.1 out of 5 from 84 reviews, 95% willing to recommend, NDR mindshare 13.9%, down from 23.4%, all August 2026. Aggregate pros: rapid detection, autonomous response, actionable alerts. Aggregate cons: high pricing sentiment, interface complexity, physical-appliance footprint.

Who is it best suited for?

The vendor claims fit across all sizes and industries with 10,000+ customers; PeerSpot research interest skews 44% large enterprise (neutral). For that specific two-horse race, see Vectra AI vs. Darktrace.

3. Corelight

Introduction

Corelight is a Leader in the Forrester Wave NAV Q4 2025, self-announced with criteria detail: highest possible scores in the deployment and administration criteria and the protocol coverage criterion (2025). Independent, co-founded in 2013 by Zeek creator Vern Paxson with Robin Sommer and Seth Hall. The product is the Open NDR Platform; Investigator is the SaaS analytics tier.

Key capabilities

The vendor's tagline is "Evidence-first, open-core NDR with AI-powered detection and Agentic Triage" (2026), consolidating Zeek monitoring, Suricata IDS, YARA file analysis, and Smart PCAP, and shipping evidence to existing SIEM and XDR consoles. In June 2026 it added, per neutral trade coverage, "native network performance monitoring and passive asset classification capabilities".

Key differences between Corelight and ExtraHop

The portability row states the practical consequence of the parsing-engine difference; capability rows remain vendor claims.

Pros and cons

On PeerSpot's Corelight Open NDR listing: 4.4 out of 5 from 7 reviews, 100% willing to recommend, NDR mindshare 4.4%, all August 2026. Praised: fleet-wide Suricata policy management and correlated evidence pivots. Flagged: price perception and multi-VM complexity. NVD returns zero results for a "Corelight" keyword search as of 2026-08-12, a database state on a date, not a security rating. Demand runs one way: corelight vs extrahop carries 150 monthly searches while the reversed form measures zero.

Who is it best suited for?

The vendor states it serves "large enterprises and government agencies in more than fifteen countries" (2026); the evaluation implication is teams that need detection logic and evidence to stay portable.

4. Arista Networks

Introduction

Arista Networks was evaluated in the Forrester Wave NAV Q4 2025. Arista NDR is the former Awake Security, acquired in 2020 and actively marketed (product page verified via 2026-08-06 snapshot); Arista's own current datasheet still titles its hardware table "Awake Security Platform Hardware Specifications", a live naming-drift example.

Key capabilities

All vendor claims: "L2 - L7 network data" with entity-centric coverage of devices, users, applications, and domains; approximately 1,200 security-specific detection features; a security knowledge graph; "Network Based Encrypted Traffic Analysis"; AVA AI decision support presenting situations rather than alert streams; adversarial modeling; and federated machine learning that keeps data in-house. Arista also claims parsing of over three thousand protocols, a different artifact than ExtraHop's decoded-protocol count with no throughput qualifier, so the two numbers never share a row.

Key differences between Arista Networks and ExtraHop

Caveat: figures in the Arista column, including its baselining characterization of a competitor, are Arista's own claims and are unverified; the ExtraHop column reflects ExtraHop's own documentation.

Pros and cons

On PeerSpot's Arista NDR listing: 4.5 out of 5 from 14 reviews, NDR mindshare 3.0%, down from 3.9%, all August 2026. Praised: query language, dashboards, knowledge graph, and the managed NDR service. Flagged: query-language learning curve, encrypted-traffic handling, STIX/TAXII ingestion asks, and API maturity.

Who is it best suited for?

Large hybrid campus, data center, IoT, and cloud estates, strongest where Arista switching already exists since sensors run as switch software (vendor framing); 48% large-enterprise researcher skew with financial services on top, and the managed option suits lean teams (neutral, August 2026).

Placement context matters when shortlisting: see the 2026 Gartner Magic Quadrant for NDR.

5. Cisco

Introduction

Cisco was evaluated in the Forrester Wave NAV Q4 2025. Its NDR product is Cisco Secure Network Analytics, formerly Stealthwatch, active, and rendered by Cisco's own blog as "Cisco Secure Network Analytics (Cisco NDR)". Precision matters: it integrates with and feeds Cisco XDR, while the SaaS sibling Secure Cloud Analytics reached end-of-sale (last order 2023-11-13) into Cisco XDR.

Key capabilities

The vendor states machine learning and behavioral modeling against a continuous baseline; encrypted traffic analysis without decryption; agentless NetFlow, IPFIX, and sFlow collection from existing infrastructure; context-enriched real-time alerts; named threat-class coverage; and Data Store scale of over 3 million flows per second (vendor materials, snapshot verified 2026).

Key differences between Cisco and ExtraHop

Licensing and telemetry rows are the decision anchors; both capability columns are the vendors' own claims.

Pros and cons

On PeerSpot's Secure Network Analytics listing: 4.1 out of 5 from 62 reviews, 88% willing to recommend, NDR mindshare 5.5%, all August 2026. Praised: reliability, encrypted traffic analytics, Layer 7 visibility. Flagged: cost perception, database hardware load, app-layer depth, ISE setup. One category-hygiene note, a listicle-quality point rather than a Cisco criticism: a page ranking for this keyword lists an SSE product as an ExtraHop alternative.

Who is it best suited for?

Enterprises that want visibility by reusing telemetry their infrastructure already generates, without sensors everywhere (vendor framing); 45% large-enterprise researcher skew (neutral, August 2026). A separate page covers how Vectra AI compares to Cisco.

6. Trend Micro

Introduction

Trend Micro is a Leader in the Forrester Wave NAV Q4 2025, self-announced via its newsroom (2025-10-15). It is a public company mid-rebrand: the NDR SKU page still renders "Trend Vision One XDR for Networks" while platform URLs redirect to the TrendAI domain (observed 2026-08-12), another live naming-drift example, stated neutrally as observed behavior.

Key capabilities

The vendor states inline plus out-of-band inspection; real-time inline blocking; behavioral and AI-based anomaly detection; native correlation in the platform's SecOps layer; automated response and retroactive forensics; and monitoring "across hundreds of protocols" with wire-speed virtual patching fed by the Zero Day Initiative (vendor pages, 2026).

Key differences between Trend Micro and ExtraHop

The credits-versus-devices licensing row is the anchor; protocol-breadth claims are constructed differently by the two vendors and are not compared as specs.

Pros and cons

The widely cited 4.3 out of 5 (115 reviews, 98% willing to recommend, August 2026) belongs to the TrendAI Vision One platform listing, not an NDR SKU rating. The NDR-adjacent module listing holds one review, anecdotal rather than a rating: zero-day and network-layer detection praised; firewall telemetry integration and risk-based tagging flagged.

Who is it best suited for?

Enterprise networks inside a consolidated platform strategy (vendor ICP), best where Vision One is already the console and credits can be reallocated; the platform's reviewer base spans small business to large enterprise (neutral, August 2026).

Signal quality is the platform question that matters most: explore the Vectra AI platform.

7. Fortinet

Introduction

Fortinet was evaluated in the Forrester Wave NAV Q4 2025 and sells two NDR offerings per its own pages: on-premises FortiNDR, pitched at air-gapped and OT environments ("Stores and processes all data locally. Nothing leaves the network.", vendor ordering guide, observed 2026), and FortiNDR Cloud, a Guided SaaS with a Technical Success Manager, a 1 Gbps-and-above qualifier, and 365-day retention. It self-announces a 2024 KuppingerCole NDR Leadership Compass Leader placement.

Key capabilities

The vendor's hero line is "AI + human insight deliver real-time threat detection, without endpoint agents." (2026). It states continuous traffic analysis for lateral movement and exfiltration; agentless OT and IT visibility with asset inventory; FortiAI-Assist investigation; 500+ third-party connectors on the Cloud offering; and neural-network malware scanning with a Virtual Security Analyst on-premises.

Key differences between Fortinet and ExtraHop

Bandwidth-versus-devices licensing is the anchor row; per-sensor throughput specs use a different denominator from ExtraHop's platform claim and are deliberately not blended.

Pros and cons

This entry doubles as the page's ratings-hygiene example: PeerSpot shows 9.6 out of 10 for FortiNDR on a displayed base of only two reviews (August 2026; NDR mindshare 2.6%). A two-review average is a sample-size lesson, not a verdict. Within that caveat: bundle value, dashboards, and FortiGuard intelligence praised; missing bundled sandbox and limited third-party firewall integrations flagged. Beyond that: Not available in research.

Who is it best suited for?

Air-gapped, government, military, and OT environments for on-premises FortiNDR (vendor ICP); 1 Gbps-plus environments wanting guided SaaS operations; platform-standardized buyers who accept consolidation trade-offs.

Analyst placement is one of the four tests this page runs: see the 2026 Gartner Magic Quadrant for NDR.

8. NETSCOUT

Introduction

NETSCOUT was evaluated in the Forrester Wave NAV Q4 2025 and is a public company (NASDAQ: NTCT). Its NDR offering is Omnis Cyber Intelligence with Omnis CyberStream sensors, self-announced Leader in the 2025 QKS SPARK Matrix for NDR. The extrahop vs netscout query draws steady demand, and the licensing contrast below is the practical answer.

Key capabilities

The vendor positions the pairing as a "scalable, investigation-focused Network Detection and Response (NDR) solution powered by deep packet inspection (DPI)" (2026): patented DPI converting packets into layer 2 through 7 metadata at the capture point, multi-method Adaptive Threat Detection, continuous full packet capture up to 100 Gbps with local storage, and enrichment of existing SIEM, XDR, SOAR, and EDR workflows. Neutral coverage of Adaptive Threat Analytics (July 2025) corroborates the investigation focus.

Key differences between NETSCOUT and ExtraHop

The licensing row is the practical gap: NETSCOUT publishes no countable unit anywhere the research could fetch, while ExtraHop publishes Discovered Devices.

Pros and cons

Not available in research. No PeerSpot listing exists for Omnis Cyber Intelligence, and the AWS Marketplace listing displays zero reviews as of 2026-08-12. Naming that blank plainly beats filling it, which several ranking pages do without a fetchable source.

Who is it best suited for?

The vendor states it serves "the world's largest enterprises, service providers, and public sector organizations" (2025): large hybrid estates that want packet-level forensic evidence retained locally at scale.

For the category fundamentals behind these trade-offs, read network detection and response.

9. NetWitness

Introduction

NetWitness was evaluated in the Forrester Wave NAV Q4 2025 and is a Visionary in the 2026 Gartner Magic Quadrant for NDR, self-announced site-wide, report dated 18 May 2026 per the vendor's own disclaimer. Ownership is current and material: NetWitness "officially joined forces with PartnerOne, a private equity firm" per its own newsroom (announced 2025-03-17), formerly part of RSA, spun out in 2020. The product is NetWitness NDR, a module of its TDIR platform.

Key capabilities

The vendor states patented real-time full-packet capture with metadata enrichment; behavioral analytics plus threat intelligence; session-reconstruction forensics with automated response; on-premises, cloud, and hybrid coverage; a searchable data lake unifying packets, logs, endpoint, NetFlow, and IoT/OT telemetry; and an OT visibility extension announced March 2026.

Key differences between NetWitness and ExtraHop

Capture-model flexibility versus a countable device unit is the licensing contrast; both self-announced 2026 Magic Quadrant positions are stated as fact.

Pros and cons

On PeerSpot's NetWitness NDR listing: 4.0 out of 5 from 15 reviews, 87% willing to recommend, NDR mindshare 3.5%, up from 2.3%, all August 2026. Praised: cross-domain pivoting from network to endpoint in one console. Flagged: ease-of-use improvements. A separate "NetWitness Platform" listing sits in the SIEM category with different figures and is deliberately not blended here.

Who is it best suited for?

The vendor's own heading: designed for large, complex enterprises, plus government agencies, where full-packet forensic depth outweighs deployment simplicity.

10. Exeon Analytics

Introduction

Exeon Analytics was evaluated in the Forrester Wave NAV Q4 2025. Independent and Swiss, with roots at ETH Zurich. The product is Exeon.NDR, renamed from ExeonTrace per the vendor's own newsroom headline dated 2025-07-29; PeerSpot still lists the legacy name as of August 2026, itself a naming-lag example.

Key capabilities

The vendor states its NDR runs "relying solely on metadata" (2026), eliminating deep packet inspection; is fully effective on encrypted traffic without decryption; combines supervised and unsupervised machine learning; ingests flow and log telemetry from existing routers, switches, firewalls, DNS, proxies, and cloud platforms; and ships software-only as a virtual machine, with no appliances, sensors, or agents.

Key differences between Exeon Analytics and ExtraHop

Metadata-only versus packet processing is the architectural anchor; active internal IPs versus Discovered Devices is the licensing contrast.

Pros and cons

Thin, and labeled as such. The only fetchable neutral assessment is a KuppingerCole Executive View dated March 2023, vendor-distributed and pre-rename: it credited appliance-free deployment, multiple ML models, and decryption-free detection, and flagged alert-only response and absent playbooks, all as of March 2023. PeerSpot shows no collected reviews under the legacy listing; NDR mindshare 0.8%, up from 0.4%, August 2026. Beyond that: Not available in research.

Who is it best suited for?

European, compliance-driven organizations in finance, manufacturing, logistics, public sector, and healthcare that want NDR from existing telemetry without packet sensors or decryption. The vendor frames DORA, NIS2, and KRITIS alignment plus Swiss and EU data sovereignty as positioning: an evaluation axis for EU buyers, not a control mapping.

Compare architectures side by side across the market on the Vectra AI platform.

How to choose the right ExtraHop alternative

The vendor list becomes a shortlist through method. The research compared nine "alternatives" sources and found nothing common to all nine: Darktrace appears in five of nine, Corelight in four of nine, and the two credible sources share only eight names (2026). These pages are built by adjacency, not substitutability. Start instead from a published, dated evaluation: the Forrester Wave NAV Q4 2025 names its twelve participants, and a category-coherent 2026 NDR vendor list (published 2026-08-07) shows what topical coherence looks like.

Know what each analyst artifact is, and check the edition. Three separate vendors each announced a Leader placement in the same 2026 Magic Quadrant, and each announcement names only itself, so a single release never tells you the quadrant's shape. As of 2026-08-12 the current editions are: the 2026 Gartner Magic Quadrant for NDR (the ExtraHop Gartner Magic Quadrant question resolves to a self-announced Leader placement there), the Forrester Wave NAV Q4 2025, the IDC MarketScape: Worldwide NDR 2024 Vendor Assessment, the 2025 GigaOm Radar for NDR (version 3), and the 2025 QKS SPARK Matrix for NDR, which supersedes the 2024 edition several ranking pages still cite. Never substitute a Network Observability report for an NDR report. For market direction, analyst market analysis of the NDR category (May 2026) describes standalone NDR declining from 2022 to 2025 under XDR consolidation, then recovering on AI-driven demand, with platform vendors capturing new spending and pure-play vendors facing renewal pressure.

Then apply ratings discipline: one machine-generated page ranks for this query while describing Vectra AI as a cloud security posture management vendor and reporting zero reviews for a heavily reviewed product. Anyone researching ndr alternatives more broadly should run the same tests across NDR solutions.

1. Start from a dated, named, independent analyst evaluation.
2. Confirm the report edition is current, not superseded.
3. Demand platform, scale, sample size, and date on ratings.
4. Test architecture portability: parser, open-source components, rule format.
5. Identify the licensing unit and how devices are counted.
6. List add-on modules that cannot be purchased standalone.
7. Verify ownership, product naming, and corporate status yourself.

What you need to be mindful of before switching to another alternative

Vendor viability is the layer no ranking page covers, and it is where shortlists quietly fail. Facts only, each with a source and a date.

Ownership and funding history

ExtraHop was acquired by Bain Capital Private Equity and Crosspoint Capital Partners for $900 million, announced 2021-06-08 and completed 2021-07-22, with $100 million in growth capital added 2024-01-09. Founded 2007 in Seattle by Jesse Rothstein and Raja Mukerji; early rounds were $5.1 million (2009) and a $41 million Series C (2014) per the ExtraHop Networks company history. It is privately held with no public stock ticker, stated as an entailment of verified private-equity ownership, which answers the ExtraHop stock question. On ExtraHop revenue, keep metric names attached: approximately $200 million in ARR at the end of 2023 (ARR), and more than $300 million in total bookings in 2024 (bookings, FY2024), with more than 40 customers at $1 million-plus in annual recurring revenue. ARR and bookings are different metrics from different years, not a growth line.

Leadership continuity

The highest-volatility fact in the research, re-verified 2026-08-12 across five artifacts and four publishers. State only what the pages positively show: ExtraHop's leadership page lists Greg Clark as Chairman and CEO, its author page labels Rob Greer "Former Employee - Chief Executive Officer", and independent trade coverage dated 2026-08-06 titles Clark as ExtraHop CEO. Rob Greer was announced as CEO on 2025-01-14; no artifact describing a transition in either direction was found, and a not-found is not a proof, so no characterization is offered. That is the sourced answer to the ExtraHop CEO question. On ExtraHop layoffs, the layoff tracker's ExtraHop page states verbatim "No layoff data found for this company." (observed 2026-08-12); anonymous accounts exist, are single-source, and are not repeated as fact.

Branding and ownership drift across the vendor set

No ranking page discloses ownership or branding changes among the vendors in its own list. The consequence: a shortlist built from stale lists will contact vendors under names, and in one case a product SKU, that no longer route correctly.

Ownership and product-name status for drift-affected vendors, verified 2026-08-12; the Muninn and guardsix row is deliberately marked unresolved.

Licensing continuity and other substitution triggers

Verify the licensing unit will not change under you: the highest-signal complaint in ExtraHop's peer reviews is precisely a move to asset-based licensing. Verify decryption requirements, analyst placement currency, and vendor continuity as a set. Two verified negatives complete the picture. First, a July 2026 cyber funding and M&A brief tracked 47 transactions and $1.56 billion in disclosed funding with no NDR vendor present: a full month of sector M&A with no NDR deal is a citable stability signal. Second, the NIST National Vulnerability Database returns zero results for both "ExtraHop" and "RevealX" keyword searches as of 2026-08-12, so there is no CVE-driven substitution trigger in this window; a database state on a date, not a security rating.

How Vectra AI closes the gaps

The gaps this page documents are method gaps: lists without inclusion rules, capabilities without labels, ratings without sample sizes, and vendors whose ownership changed under the lists that recommend them. Vectra AI's answer to the category is to publish method. The one citable fact here is analyst placement: Vectra AI is named a Leader in the 2026 Gartner Magic Quadrant for NDR, confirmed by its own announcement. Everything else is a labeled claim, exactly as this page has treated all ten vendors.

The vendor's own framing: "Vectra AI protects modern AI enterprises from modern AI-powered attacks." (brand documentation, self-reported). Its stated approach rests on three pillars, "Observability, Signal, and Action": observe the hybrid network as one attack surface, apply AI to separate attacker behavior from noise, and act on prioritized signal rather than alert volume. Mapped against this page's findings, that methodology mirrors what defensible vendor selection requires: a transparent rule for what gets attention, labeled evidence behind every claim, published licensing terms, and verified status over marketing recall. Vectra AI is also not a market-fact source anywhere on this page; its capability statements received the same "vendor states" treatment as everyone else's, and its declining mindshare figure was published next to ExtraHop's. That is the standard worth holding any shortlisted vendor to.

If RevealX is the incumbent you are scoring against, start with how Vectra AI compares to ExtraHop.

Conclusion

A shortlist is only as defensible as the rule that built it and the date it was checked. This page's rule is published: Forrester Wave NAV Q4 2025 evaluation, confirmed 2026 Magic Quadrant cross-checks, product substitutability, and corporate status verified 2026-08-12. Whichever ExtraHop alternative you pursue, or if you conclude no ExtraHop alternatives fit and renew instead, do the two checks nobody's list does for you: confirm what the license is counted in, and confirm who owns the vendor and what the product is called today. Both change more often than feature sets do.
