The world got fast
Prompt injection, over-permissioned tools, silent data egress: risk moved from static documents to live agent decisions across OpenAI, Claude, Google, Copilot, and whatever ships next Tuesday.
Agentic AI security · Trust as a Service
Your AI agents read documents, call APIs, and move money while your teams trust their actions. Lineation gives security and platform teams one line of defense across every model and tool—policy that travels with the workflow, runtime truth on the endpoint, and an incident story your auditors can follow.
Free to start · Self-hosted & air-gapped options · First policy live in under a day.
The story
Agents became chains of thought. Chains became workflows that act on their own. The old perimeter never touched that story. Lineation exists so your organization can see the arc—from intent to action—and intervene before regret ships to production.
Prompt injection, over-permissioned tools, silent data egress: risk moved from static documents to live agent decisions across OpenAI, Claude, Google, Copilot, and whatever ships next Tuesday.
Cloud gateways see part of the truth. Endpoint tools see another. Nobody held a single, agent-native narrative until the incident landed in Slack without context.
One policy plane. Distributed enforcement where work actually happens. Immutable lineage from prompt to tool to data to actor so SecOps moves in minutes, not days.
The platform, in three moves
Lineation organizes agent security into three layers you can adopt in order— starting with visibility and ending with active defense.
"See what your agents are doing."
"Control what your agents can do."
"Stop your agents from being hacked."
Architecture
Decide in one place, prove everywhere else. A single control plane normalizes every provider; a lightweight daemon enforces the same rules where agents actually execute. Default-deny on high-risk actions, with override workflows.
Reasoning audit trail
Standard logs tell you an action occurred. Lineation tells you why. Every significant interaction is captured as a chain you can query, export, and replay in front of an auditor.
Outcomes
Design-partner targets for teams operating multi-provider agents. We obsess over activation: policy live, daemon coverage, and a real incident workflow.
Why Lineation
Most tools secure one layer. Lineation is the coordinated, cross-provider control plane that spans agent runtime, endpoint execution, and the full workflow trace— with audit-ready evidence at the end of it.

Operationalize widely used agentic-AI and security guidance—not replace audits or attestations. See how product capabilities map to industry frameworks; we do not imply endorsement or certification.
Lineation is not endorsed by, certified by, or affiliated with OWASP, NIST, or any standards body. Templates and “mapped to” describe implementation aids and control coverage—not SOC 2 Type II, HIPAA attestation, or EU AI Act conformity by default.
Goal hijack, tool misuse, identity abuse, memory poisoning, and rogue agents—addressed with policy-as-code, machine identity, lineage, detection, and kill-switch.
