Trusted by engineering teams at
AI agents introduced a new attack surface. Most teams have no playbook.
Skills are installed with no visibility, execute with full trust, and a malicious or misconfigured skill won't announce itself. Tessl is the control plane for agent skills. Every skill that enters your environment is scanned, scored, and governed, before it touches production.
No Visibility
Teams can't detect threats they can't see. Skills run across dev environments with no record of what's installed, who approved it, or what version is active.
Automated Governance
Encode security standards as skills. Mandate them across the org automatically, apply them at every PR, and improve them with a continuous eval loop.
No Controls
Agents don't sandbox skills. They execute them. Without policy gating, one bad instruction can become a full credential exfiltration.
Secure Consumption
Every skill in the Tessl registry is security-scanned and scored before installation. Gate by source, severity, and version with org-level policy.
No Enforcement
Security standards live in wikis. As agents act autonomously, the gap between policy and what actually runs keeps growing.
Full Visibility
Know what every agent is running, who approved it, and when. Skill inventory, admin audit logs, and analytics surfaced to org administrators.
SECURE CONSUMPTION
Scanned, scored, and ready before installation
A malicious skill doesn't look different from a legitimate one. Every skill in the Tessl registry is automatically audited before it reaches your environment, so you have a verified security signal at installation, not a forensics problem after the fact.
Security badge and automated audit on every registry skill
Private registries for org-scoped skill distribution
Install & publish policy gating by source, severity, and version
VISIBILITY
Always know what your agents are running, and why
You can't govern what you can't see. Tessl surfaces complete skill inventory across your development environment, paired with admin audit logs that track every install, block, and approval decision.
Full skill inventory scoped to Tessl-managed agents
Admin audit logs with actor, timestamp, and policy context
Analytics and reporting for org administrators
SIEM export for security team integration
GOVERNANCE
Security standards that agents actually follow
Define your security policies, coding standards, and safety boundaries once, as a skill, and Tessl enforces them automatically: during development, at code review, and across agentic flows in your org.
Encode security standards into skills agents apply automatically
Tessl-powered code review checks against your policies
Mandated skills pushed automatically, no manual install
Policy-driven PR enforcement with eval feedback loop
Why skills need their own security model
“The agent ecosystem is where open source was fifteen years ago — rapid innovation with very little security infrastructure, but agent skills introduce a new challenge: they shape autonomous behavior through natural language, meaning we need models that understand intent. What we're doing by integrating Snyk directly into the Tessl Registry is establishing those vital trust signals early. We're ensuring the agent ecosystem grows with security built in, not bolted on afterward.”
