    Preemptive Exposure Management Is the Goal. Autonomous Attack Validation Is How You Get There.

    March 4, 2026
    Reacting to cyberattacks has never been a winning strategy. Most organizations know this, yet many still find themselves responding after the fact, investigating incidents, explaining impact, and rebuilding trust with leadership. What’s changed is a growing recognition that risk must be reduced before attackers act, not measured after the damage is done. That’s the promise…
