Every AI agent is an identity — authenticating to applications, moving laterally, accessing sensitive data around the clock, often with no human watching. And not every AI risk arrives as an agent; some of it is an application your user installed last week, running with the same permissions they have. As AI adoption accelerates, non-human identities are now the fastest-growing access risk most enterprises aren’t tracking. Don’t let the fastest-growing identity category be your biggest blind spot.
Risk we ingest
Portnox integrates with best-in-class AI platforms — CrowdStrike, SentinelOne, Microsoft Defender — and converts their intelligence into immediate, policy-driven access enforcement. Every risk signal becomes an enforcement action. No manual review. No delay.
RISK WE SEE OURSELVES
AI agents don’t get a free pass just because they’re not human. Portnox enrolls every agent with strong, policy-bound credentials and ties each AI identity to a defined access policy that your employees live under. The moment behavior goes anomalous, access is gone.
And risk doesn’t only arrive as an agent. Portnox’s own endpoint intelligence surfaces the unapproved AI applications already installed on your users’ devices.
AI-Powered Integrations
Portnox brings AI-driven insights to every access decision, powered by real-time threat intelligence—enforcing zero trust across all identities.
Falcon Platform · Zero Trust Assessment
Portnox reads CrowdStrike’s AI-generated device risk score (0–100) via API — evaluated across 120+ endpoint signals including OS posture, sensor health, threat detections, and behavioral patterns. Devices that drop below your threshold are instantly blocked or quarantined. No analyst required.
Singularity Platform · Purple AI
When SentinelOne’s autonomous AI flags a device — detected threat, anomalous behavior, or failed compliance — Portnox enforces immediately. Block, quarantine, VLAN re-segment, or revoke access. The signal fires; we act.
Defender · Risk Rating
Portnox reads Microsoft Defender’s device Risk Rating via API and enforces access policy accordingly. Defender flags the risk; Portnox acts on it — blocking or quarantining devices that fall outside your defined threshold.
Shadow AI Control
Not every AI risk authenticates like an agent. Some of it is an assistant an employee installed last Tuesday — reaching local files, remote resources, and enterprise data with the same permissions as the logged-in user, entirely outside your policy. It’s the same posture data already covering drive encryption, open ports, and administrator privileges.
Portnox inventories AI applications installed on Windows and macOS endpoints — ChatGPT, Microsoft Copilot, Claude, Google Gemini, Perplexity, DeepSeek, Cursor, Codex, and Ollama, alongside dozens of other AI assistants, coding agents, local models, and image-generation tools, with coverage expanding as new ones emerge.
Define which AI applications are permitted and which are prohibited — then assign an AI Risk Level to anything that falls outside the list. An assistant your security team has cleared is not the same as one nobody has reviewed, and the policy shouldn’t treat them alike.
What’s installed scores the device. AI Risk Level feeds device risk assessment like any other posture condition — then policy acts. Remove the application, restrict the device to specific resources, or block it from the network. You choose the action per policy.
Detection is only worth having if you can act on it proportionately. Blocking a laptop because someone installed an assistant is a policy no security team will ever turn on. Remediation removes the offending application and leaves the employee working — which is why AI Risk Level and Remediation ship on the same agent, in the same release.

Hard deny — device or agent refused network access entirely
Isolate to a restricted segment with no access to production resources
Access revoked — network and application access cut off.

How It Works
The enforcement loop, explained: from risk signal to policy enforcement — entirely automated, auditable, and operating at machine speed.
CrowdStrike, SentinelOne, or Defender flags anomalous behavior or elevated device risk — or the Portnox agent surfaces an unapproved AI application on the endpoint.
The policy engine receives the risk signal and evaluates it against your defined access policies in real time.
Remediate, restrict, quarantine, or block — the action is defined by your policy, not chosen by the product.
AI Identity Security
AI agents, assistants, and automation workflows are non-human identities that need the same access controls as your employees — and the same enforcement the moment they step out of line. Portnox controls unapproved AI applications the moment they land on a device, and restricts access the moment an AI identity already operating in your environment turns risky. Two problems, one policy engine.
Core Mechanism
AI agents operate on your network just like employees — authenticating to applications, making lateral moves, accessing sensitive resources around the clock. Portnox enforces zero trust policies for every identity, not just every person. Every AI identity is enrolled with scoped access that can be cut off in one move — across every layer simultaneously.
If CrowdStrike detects an agent acting anomalously, Portnox blocks its access to the network and every application — instantly. A network-level kill switch for any identity, human or not. No manual step required. We pull the plug.
Every AI identity gets access to exactly what it needs — nothing more. Strong credentials tie each AI identity to a defined, scoped access policy.
Access granted at certificate issuance is enforced throughout the session. Posture changes trigger automatic, action.
The same zero trust principles that govern your users and devices now govern your AI agents — same enforcement, same visibility, same audit trail.
At Scale
Portnox secures every identity — human and non-human — across networks, applications, and infrastructure. More than one million devices managed worldwide. 40 million authentication sessions secured. Over one million unauthorized access attempts blocked every day.
Compliance Coverage
Visibility and control over access events for AI-driven identities — tracking who connected, when, from where, and under which policy, with enforcement informed by endpoint intelligence.
Whether you’re a CISO making the business case or a network engineer deploying in the field, Portnox’s AI capabilities deliver at every level.
