Continuous Security Validation in a World of Agentic AI | A Brand Spotlight at RSAC Conference 2026 with Matt Stewart and Alex Grohmann of Impetum

The security industry has spent years debating which tools to buy. Impetum is asking a different question: are the tools you already have actually working? Founded by incident responders who saw the same failures across hundreds of breaches, Impetum built the Persistent Purple Team platform to simulate advanced threat actors inside customer environments on a continuous monthly basis -- not as a one-time engagement, but as an ongoing relationship built around real data, custom TTPs, and a measurable Threat Resilience Score.

Matt Stewart and Alex Grohmann spoke with Sean Martin and Marco Ciappelli at RSAC Conference 2026 about what they are hearing on the show floor: agentic AI is accelerating the speed of compromise and exposing vulnerabilities in legacy systems that have been dormant for decades. Against that backdrop, the value of knowing -- not assuming -- that your detection and response capabilities hold up becomes critical. The platform builds that knowledge through live-fire exercises using an organization's own data, validating patch management, XDR, SIEM tuning, and post-compromise detection in a way no annual pen test can.

The conversation also touched on the structural talent problem agentic AI is creating inside SOCs. As AI fills the level one analyst role, the pipeline for developing level two analysts and incident responders is narrowing. Impetum sees persistent purple teaming as the training ground that closes that gap -- giving existing teams the repeated, realistic practice they need to respond with confidence when an actual breach begins.

Impetum targets mid-size organizations that have the right security tools but lack the budget, bandwidth, and access to industry events to keep those tools continuously validated against evolving attack paths. For those teams, the platform delivers something an annual report cannot: a documented, ongoing record of what works, what does not, and where the program is heading.
