Overview
- Stop dangerous AI agent actions before they execute with runtime protection that blocks the harmful step in real time rather than alerting after the fact
- See every move your AI agents make across endpoints, containers, and cloud through one live session timeline that correlates OS activity, network and API calls, and model reasoning
- Achieve full auditability of autonomous agent behavior with session auditing that traces what each agent did after authentication and under its authorized intent
- Eliminate blind spots in your infrastructure by automatically discovering AI agents wherever they run, including coding agents and production cloud agents
- Deploy runtime agent security in minutes with a single lightweight sensor that runs inside the agent's own process, requiring no gateways, proxies, or code changes
- Complete a full agent risk assessment in three hours or less to quantify exposure before attackers exploit your agentic deployments
- Extend protection across your existing agent ecosystem with vendor-neutral guardrails that work with Claude and other agent frameworks
- Defend against agentjacking, ghostjacking, and other agentic kill chains uncovered by original threat research from the team that built Cisco's AI Defense
- Govern unpredictable agent behavior with real-time blocking and a live kill switch that actually stops a rogue agent mid-action
- Protect tens of millions of end-users across enterprise environments by governing what agents do after they are authenticated, the behavioral layer identity, posture, and prompt guardrails cannot see

❓ Frequently Asked Questions
Tenet Security is a security platform built for the agentic era, designed to protect enterprises as they deploy autonomous AI agents. Rather than only detecting attacks after they happen, Tenet focuses on preventing them at runtime, before they execute.
Agentjacking is an attack class discovered and named by Tenet's Threat Labs team, where an AI coding agent is hijacked into running attacker-controlled code, triggered by something as simple as a fake bug report, without malware or a traditional exploit, and often invisible to existing security controls.
GhostJacking is a related attack technique presented by Tenet at DEFCON, showing how AI agents can be taken over using requests that even get blocked by a firewall, exploiting tools already deployed across roughly half of the Fortune 500.
Tenet establishes control at the runtime layer, monitoring and governing agent behavior across endpoints, containers, and cloud so that even unpredictable agent actions behave predictably, and unauthorized actions can be stopped before they execute.
Yes. Tenet Security is part of the Claude Partner Network, extending agent discovery, session auditing, and runtime protection across the Claude ecosystem.
Tenet emerged from stealth in mid-2026 with $6 million in seed funding led by The Westly Group (an early SentinelOne investor) and MizMaa Ventures. The company is advised by former CISOs from Robinhood and BNY, among other enterprise security leaders.
Yes. Tenet was named a finalist in the 2026 Top InfoSec Innovator Awards in two categories, won the 2026 Fortress Cybersecurity Award for Agentic AI Security Platform, and appears in the Cloud Security Alliance's Agentic AI Security Market Map across Governance, Observability, and Vendor-Neutral Guardrails.
Tenet doesn't currently offer self-serve signup based on public information, you can request an Agent Risk Assessment or book a demo directly through their site.
