Greenhill Stops Cyberattacks from Enterprise to Office 365 SaaS with Vectra

Challenge

Greenhill was grappling with a lack of visibility into its network, making it tough to distinguish which threats were significant and required attention. Moreover, the company was facing issues with alert fatigue due to an overwhelming volume of security logs, and was particularly concerned about the rising incidents of credential abuse and account takeovers in SaaS platforms like Microsoft Office 365.

Solution

Greenhill deployed the Vectra AI Cognito platform, an AI-driven solution that provided real-time, automated detection of cyberattack behaviors. In addition to managing security on their network and data centre, Cognito Detect was also deployed for Microsoft Office 365 to proactively identify and respond to hidden cyberattackers and prevent data breaches.

Customer benefits

Vectra AI's solution gave Greenhill complete visibility across its entire network, reducing the event workload by filtering through security logs and giving priority to the most critical threats. This allowed more focused time on investigations and proactive threat hunting instead of chasing logs. Additionally, the artificial intelligence-based algorithms developed by Vectra learned to distinguish between normal behavior and malicious activity, saving valuable time and effort for the company's security staff.

“Attackers today evade firewalls, IDS and other legacy security systems and spread inside the network looking for assets to steal.”

“Vectra gives us a head start in the network and CrowdStrike speeds across the finish line at the endpoint.”
