Granting AI agents excessive permissions opens new vulnerabilities; modern protection requires proactive governance to prevent machine behavior from drifting.

In the world of cybersecurity, the concept of "Zero Trust" has long served as the first line of defense for protecting data and systems. But with the emergence of AI agents as a third type of actor—combining the speed of machines with human-like autonomy and unpredictable behavior—traditional protection models face an unprecedented challenge, requiring a shift from mere "Zero Trust" to "agent-trust governance".

Field indicators reveal a security gap resulting from the rapid adoption of these technologies:

  • Only 3% of organizations: Have automated tools to govern AI systems and monitor their behavior during live operation.
  • 4.5 times as many security incidents: Companies that grant AI agents excessive permissions without strict oversight experience this level of increase.
  • 70% of organizations: Grant AI systems greater access and usage permissions than they grant a human employee in the same role!

The Required Shift: From «Zero Trust» to «Agent Trust»

To address these risks, modern cybersecurity requires adopting a unified identity layer that treats humans, machines, and agents as first-class actors, with permissions determined dynamically through three core pillars:

  1. Continuous enforcement instead of explicit verification: Real-time monitoring of an agent’s behavior during execution rather than relying solely on identity checks at login.
  2. Constraining collective autonomy instead of granting least privilege: Controlling the boundaries of interaction between AI agents to prevent sequential autonomous decisions.
  3. Assuming goal drift instead of assuming only a breach: Guarding against changes in an agent’s behavior or its taking unexpected paths to reach an outcome.

Strategic takeaway: «Modern protection cannot rely solely on traditional Zero Trust; it requires firm, proactive governance of the third actor.»
