About
Pentera is an automated security validation platform that continuously simulates real-world cyberattacks across an organization's network and infrastructure to identify, prioritize, and validate security gaps before adversaries can exploit them. Unlike traditional penetration testing — which is manual, periodic, and expensive — Pentera's platform runs continuously and autonomously, emulating the tactics, techniques, and procedures (TTPs) of real threat actors to produce a prioritized remediation roadmap that security teams can act on immediately. The platform covers network, endpoints, Active Directory, cloud, and web application attack surfaces.
