Identity is the control plane
in the age of agentic AI.

Agents move fast, create new attack paths, and expose hidden identity debt.

Every user, workload, and agent depends on identity providers like Active Directory, Entra ID, and Okta.

When identity fails, business stops.

Rapid AI adoption is reshaping identity risk

  • AI search exposes hidden identity debt in permissions
  • Agents can go rogue: Detection and containment must be immediate
  • Agent-to-agent interactions introduce new escalation paths
  • Agent command authority is becoming the new attack surface
  • Mission-critical operations depend on agent uptime, requiring resilient identity systems

In a world where ransomware can shut down hospitals and pipelines, wiring unguarded AI into Active Directory, Entra ID, or Okta isn’t innovation—it’s the fastest route from ‘productivity booster’ to full-scale business outage.

If identity
isn’t secure,
nothing is

Over 80% of all breaches involve credential abuse
Humans AND agents rely on IdPs for authentication and authorization
Systemic weakness make AD a soft target
A compromised IdP gives attackers the keys to the kingdom, including control of agents
​Cloud identity stores extend from AD
Hybrid, cross-cloud IdP resilience is complex
Zero trust model assumes AD integrity
Active Directory remains the identity source of truth in most organizations

Identity-first security for hybrid identity environments

Semperis delivers end-to-end security and resilience across the identity fabric, spanning all major IdPs and supported by a global identity forensics and incident response (IFIR) team.

TOP 5 FASTEST-GROWING CYBERSECURITY COMPANIES​

“Cybersecurity programs, big and small, are on the front lines of a new war that has virtually no boundaries and no rules of engagement. If you think about hospitals that can’t access their systems to save a life, or cities that get held hostage, we have a responsibility to help organizations take back control. That’s what drives us.” – Mickey Bresman | Semperis CEO
