Tenet Security

Tenet Security is a security platform built specifically for the new wave of autonomous AI agents. It helps organizations detect and stop agentjacking attacks — where an attacker tricks a trusted AI agent into executing malicious code, accessing sensitive data, or taking unauthorized actions. The platform gives security teams a clear view of every agent running in their environment, including ones they didn't know existed, and constantly monitors for suspicious behavior like prompt injections, privilege escalations, and unexpected code execution.

What makes Tenet Security stand out is its focus on the agent runtime. Instead of just scanning for known vulnerabilities, it watches agents as they act, catching attacks that happen in seconds. The system uses behavioral analysis to spot anomalies — for example, a coding agent that suddenly tries to read internal databases or a customer support agent that starts sending data to an external server. Tenet Security also enforces least-privilege policies automatically, so even if an agent is compromised, the damage is contained. The platform was presented at DEFCON, where researchers demonstrated how they took over agents at over 100 global companies, showing just how real the threat is.

This tool is most useful for security teams at enterprises that deploy AI agents for tasks like code generation, customer support, or internal process automation. It also helps IT administrators who need to manage and audit agent usage across their organization, and AI developers who want to build safer agents from the start. With Tenet Security, you don't have to choose between moving fast with AI and keeping your data safe — you can do both.
