One good output doesn't make a system reliable. Certigen models acceptable execution paths and verifies live agent runs against them — across every step, tool call, and decision.
In published research across 100+ scenarios and seven domains, 62% of agent runs exhibited safety failures invisible to single-step tests. Tool-involved interactions produced 46% more failures than non-tool interactions — because the risk lives in how tools are chained across steps, not how any single tool is called. A guardrail can check each invocation. It cannot check the sequence.
Every existing tool answers a point-level question. None of them answer the one that matters in production.
That question cannot be answered by combining existing tools. A guardrail checks each tool call in isolation — but agents that pass every individual check still fail across the sequence. Tool-involved interactions produce 46% more safety failures. The risk lives in paths, not points.
Trajectories aren't logs — they're typed, structured objects with a schema that can be queried and verified. Certigen checks the entire sequence of decisions and state transitions against your contracts. Express temporal constraints no single-step tool can: "A must happen before B, regardless of what happens in between."
A guardrail blocks one action. A behavioral contract specifies valid sequences — which steps must precede others, which transitions are forbidden, when human escalation is required. Contracts reason over paths, not snapshots. Versioned, composable, and enforced across agent boundaries.
Contracts verify individual runs. Invariants verify properties across your entire fleet — statistical guarantees like "no more than 2% of trajectories should trigger manual override." When an invariant breaks, Certigen identifies which trajectories shifted the distribution, not just that a number moved.
Verification isn't binary. Every result includes multi-dimensional risk assessment — operational, content, societal, and legal — plus the full proof trace showing what was checked, which dimensions passed, which failed, and the exact step where the trajectory diverged.
Define acceptable behavior as formal contracts, validate agent runs against them, and verify conformance in production.
Define acceptable behavioral sequences for your agents — not rules about individual actions, but constraints across entire execution paths. Certigen's contracts express temporal constraints over agent trajectories — which steps must precede others, which transitions are forbidden, when human escalation is required.
Replay agent runs against your behavioral contracts. Certigen checks every trajectory for contract conformance.
Continuously verify live agent runs against contracts. Flag violations, block unsafe actions, and maintain a complete audit trail.
Where compliance is mandatory, not optional.
An agent handling patient intake queries a records system, retrieves PHI, and passes it to a scheduling tool — without verifying that the requester is authorized to access that patient's data. Each tool call succeeds. The trajectory violates HIPAA. Certigen catches the sequence.
A loan processing agent pulls a credit report, generates a risk score, and issues a pre-approval — but skips the required adverse action notice for a borderline applicant. Every step is technically correct. The sequence violates Reg B. Certigen catches the sequence.
Agent A retrieves sensitive data. Agent B summarizes it. Agent C emails the summary externally. No single agent violated a rule. The three-agent trajectory leaked confidential information. Certigen verifies behavior across agent boundaries.
Give platform teams a single verification layer for agent behavior across the organization. Maintain standards without slowing down product teams.
Certigen's verification framework is grounded in peer-reviewed research across 100+ safety-critical scenarios spanning healthcare, finance, science, education, and more — validated against independent domain expert judgment.
State-of-the-art LLMs exhibited safety risks in 62% of thousands of simulated agent runs. Not because individual outputs were bad — because the sequences of actions violated behavioral constraints that single-step tests can't express.
Dynamic multi-turn trajectory analysis surfaced up to 3× more safety failures than static single-turn benchmarks. Static test datasets become obsolete because models memorize them. Multi-turn interaction sequences can't be memorized.
Agents in tool-involved interactions under adversarial conditions produced 46% more safety failures than non-tool interactions. The risk isn't in any single tool call — it's in how tools are chained. Guardrails check invocations. Certigen checks sequences.
Even well-intentioned users with vague or underspecified instructions can trigger unsafe agent trajectories through the accumulation of individually reasonable steps. Verification isn't just about catching adversaries — it's about catching the sequences where good intentions still produce bad outcomes.
No new runtime. No vendor lock-in. Certigen integrates at the agent layer — any LLM, any framework, any tool.
