The Identity Resilience Platform

Agentic readiness
starts with
identity resilience

Trusted by the world’s largest enterprises and government agencies for more than a decade, we understand the complexities of identity-first security & crisis management like no one else.

Speak with an expert Reduce AI Identity Attack Risk

150+ million identites protected

We protect the most complex Active Directory environments, Global 2000 companies, and government agencies from cyberattacks, data breaches, and operational errors.

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

Every user, workload, and agent depends on identity providers like Active Directory, Entra ID, and Okta. As your business bets more on agents, it bets more on your identity fabric.

If identity fails, so do the agents—and every person and process they support.

Reduce Identity Attack Risk in the AI Age

In the hands of attackers, agents move fast, create new attack paths, and exploit hidden identity debt at machine speed. How can you unlock the productivity benefits of agentic AI—while preventing rogue agents from instigating a cyber disaster?

Semperis helps you protect your identity fabric before, during, and after a cyberattack.

Pre-attack:
Shrink your identity
attack surface

– Deploy continuous monitoring + constantly updated indicators
– Find and fix vulnerabilities in human and non-human identities
– Uncover and remediate Tier 0 attack paths
– Modernize the identity environment

During the attack:
Stop identity attackers in their tracks

– Deploy pattern-based attack detection and response
– Control who—or what—can command your agents
– Spot rogue behavior and block misbehaving agents
– Uncover and remediate attacks that evade traditional monitoring
– Identify and secure non-human and machine identities

Post-Attack:
Recover identity to
a trusted state

– Apply expert cyber-first identity forensics and incident response (IFIR)
– Use purpose-built forensics tools to return the identity system to a trusted
– Deploy unmatched enterprise cyber crisis management to reduce downtime and mitigate risk

Is your identity fabric ready for agentic AI?

Recognized for our battle-tested identity resilience expertise, Semperis helps organizations prevent, detect, respond to, and recover from agentic and conventional identity attacks.

If identity
isn’t secure,
nothing is

Humans AND agents rely on IdPs for authentication and authorization

A compromised IdP gives attackers the keys to the kingdom, including control of agents

Hybrid, cross-cloud IdP resilience is complex

Active Directory remains the identity source of truth in most organizations

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.
