CORTHEM detects decision drift: machine actions allowed under past policy would be governed differently under current policy. It verifies decisions across time, classifies drift across four axes, and produces signed, audit-grade evidence bound to a tamper-evident verification chain, evidence any party can verify independently, offline. And it verifies not only the decision, but the reasoning chain behind it.
Founding Member release · Enterprise briefings available · Deploys inside customer environments. Never SaaS.
Agentic systems are already triggering workflows, modifying records, calling APIs, and routing decisions inside enterprise environments. Most organizations still rely on logs, reviews, and reconstruction after the fact.
Continuous Governance Verification Infrastructure is the layer enterprises need when agentic systems are already operating and the ability to prove policy-governed behavior is no longer optional.
Not a platform. Not a dashboard. Not another compliance surface.
Infrastructure: embedded, load-bearing, and built to hold under scrutiny.
Observability confirms activity. It does not verify that machine action remained within policy at the moment it occurred, under the policy that was actually in force.
Audit tools reconstruct history after the fact. That is not the same as maintaining a verified, decision-linked evidence chain across time as systems act.
Compliance frameworks define requirements. They do not produce proof that machine action remained governed as it happened, across workflows, records, and downstream systems.
Not a snapshot. Not a quarterly review. CORTHEM maintains continuous verification state across agentic activity, so proof remains live as systems act. Severity-routed alerts fire the moment drift crosses policy thresholds, not in the next review cycle.
Every governed action produces a decision-linked record: what was requested, what policy applied, what outcome occurred, and why. Every record is signed and chain-linked. Altering a single byte anywhere breaks verification, and evidence verifies offline, without access to CORTHEM or to your systems.
When leadership, counsel, auditors, or regulators ask for proof, you have signed, independently verifiable governance artifacts, not partial observations reassembled after exposure.
Oversight for agentic systems is forming now. CORTHEM helps enterprises establish proof before external demands arrive.
CORTHEM classifies every drift event across four deterministic axes: auditable, reproducible, and structured for procurement-grade defensibility.
What changed: policy (rule modification), context (input state changed), outcome (decision flipped), or compliance (regulatory mapping shift).
Critical for ALLOW→BLOCK on production-impacting actions. Material for any decision flip. Advisory for constraint parameter changes.
Which rule fired differently. Which input attribute changed. Or both. Rule-level diff and attribute-level diff, every time.
Drift accumulation over time, per partner, per policy bundle, per rule, per actor class. Direction matters as much as magnitude.
Every CORTHEM API response and every console view surfaces all four axes. Decision drift requires a runtime authority architecture to be meaningful, and CORTHEM is the only product purpose-built to verify it across time. The same four axes classify detection drift on the reasoning layer.
Behind every machine action is a reasoning chain: the goal, instructions, and retrieval provenance that produced it. That chain can carry contamination no detector of its day could see: prompt injection, retrieval poisoning, instructions that were never yours. A frozen log preserves the contamination forever. A fire-once enforcement layer never looks again.
CORTHEM captures the reasoning chain, cryptographically binds it to its authority event and policy version snapshot (trace binding) and replays it against later, improved detection policy. When today's detectors surface what yesterday's could not, that is detection drift: decision drift applied to the reasoning layer. Every finding is classified across the four axes, severity-routed, and appended to the verification chain as signed evidence.
The novel step is temporal: replay of bound reasoning against detection capability that did not exist when the decision was made. Shipped, demonstrated end to end, and the subject of a pending patent application.
Can tell you something happened.
None of these prove that agentic execution remained governed continuously: under the policy actually in force at the moment of action, with the context that actually existed, and with evidence retained per decision before downstream systems acted on it. Activity surfacing is not governance proof. Process maturity is not governance proof.
Can help reconstruct history.
Can define intent, document process maturity, satisfy SOC 2 / ISO scoping.
Can govern users, models, or access domains.
"We reviewed it later" is not a governance position.
CORTHEM continuously verifies whether agentic activity remained within policy, preserves decision-linked evidence, and produces governance artifacts enterprises can retain, review, and defend.
It does not wait for review cycles to assemble proof.
It does not reconstruct governance from fragmented logs.
It verifies as systems act and preserves the evidence trail as they do.
CORTHEM evidence is emitted as a signed artifact (an Ed25519 envelope over canonically serialized evidence). A standalone verifier checks the signature and the chain linkage with no database access and no running service. If a single byte has changed, verification fails. That is what audit-grade means here: proof that does not require trusting the vendor, or the customer. Reasoning traces are bound the same way, to their authority event and policy version snapshot inside the verification chain, so reasoning evidence verifies offline exactly like decision evidence.
Retention with integrity: records prune only behind a signed checkpoint, so the surviving chain stays verifiable end to end.
✗ Not a retrospective audit log
✔ Continuous verification across time
✗ Not an observability dashboard
✔ Decision-linked evidence tied to policy
✗ Not a compliance checklist tool
✔ Governance infrastructure built for defensibility
✗ Not model governance or IAM
✔ The verification layer those systems do not provide
Intercepts machine-initiated execution and enforces authority before downstream systems act.
Continuously replays decisions and reasoning chains, classifies decision drift and detection drift, and produces signed, audit-grade evidence bound to a tamper-evident verification chain.
Together they form a closed-loop control and evidence architecture: runtime enforcement paired with continuous verification, hash-chained from execution through to evidence.
CORTHEM stands on its own. It remains valuable in any environment where agentic systems operate, regardless of whether enforcement is native, external, partial, or absent. CORTHEM deploys inside customer environments: never SaaS, never hosted, never reaching into systems it does not own.
As agentic systems begin acting across workflows, records, APIs, and downstream enterprise systems, the governance burden changes. It is no longer enough to define policy, monitor activity, or reconstruct incidents later.
Enterprises need the ability to prove that machine action remained governed continuously, under current policy, across time.
