Why Security Teams are Replacing IDS and IPS with NDR

With the increasing complexity of the network and the growing sophistication of attacks, organizations are reassessing their security strategy. It is becoming more difficult to distinguish attacker behavior and prevent serious breaches, data theft, and ransomware using standard network security tools. Intrusion detection systems (IDS), intrusion prevention systems (IPS), and the convergence of the two, known as intrusion detection and prevention system (IDPS), have been considered vital in uncovering and preventing unwanted and/or malicious activities in the network. Still, many breaches are unabated, highlighting how organizations need to address the protection of internal assets better and improve their ability to detect atypical threats born in the network and stop nefarious lateral movement.

IDPS offers in-line protection that enables security professionals to identify and block potential threats, intrusions and attacks on an organization’s networks, applications or systems, automatically. IDPS uses various techniques to detect and block known attacks with high confidence, significantly assisting IT operations teams where patching cannot be executed in the same time scale as threat actors are operating.

But today, even when combined with other tools like XDR, EDR, SIEM, and firewalls — organizations using IDPS can’t easily discern unknown active threats and stop sophisticated attacks already inside. IDPS systems suffer from many downsides that make them inefficient in stopping modern cyberattacks and improving response and investigation workflows.
