MYTHOS is an adversarial certification framework that tests a governance layer against six distinct attack families and emits hash-linked proof of each result. The output is not a marketing assertion — it is an evidence chain a third party can verify without trusting the party that produced it [VC-C].
The design problem it addresses is that assurance decays. A system validated at deployment is not a system validated today: vendors update models the customer does not control, input distributions shift, calibration drifts — and an adversary who can induce overconfidence can push unsafe decisions past a trust threshold without tripping an anomaly alert. Point-in-time validation cannot detect any of that. Continuous adversarial certification can [VC-C].
Request the certification briefing§ 1 · THE MECHANISMHow Certification Produces Verifiable Evidence
Each certification run exercises the governed deployment against the six attack families and records every result into a hash-linked chain: each entry binds to its predecessor, so no result can be silently removed, reordered, or altered after the fact. Verification requires only the chain and the published interface — not access to MYTHOS internals, and not trust in VectorCertain [VC-C].
The certification surface itself is stability-sealed: MYTHOS ships as a sealed 20-name published interface, verified across subsequent engineering sprints by exact frozen-set equality — no name added, removed, or re-spelled — so downstream consumers can depend on the surface without version drift [VC-C].
| Property | Typical attestation | MYTHOS certification |
|---|---|---|
| Basis | Vendor statement | Executed adversarial tests, six families |
| Evidence form | Document or badge | Hash-linked chain, entry-by-entry |
| Tamper resistance | Trust the author | Any removal or edit breaks the chain |
| Verifier requirements | — | Chain + sealed 20-name interface only |
| Freshness | Point-in-time | Continuous; each run appends |
| Third-party scenarios | Rare | Standing invitation to evaluators |
§ 2 · THE DIRECTIONWhy Regulation Is Moving Toward Continuous Evidence
The NIST AI RMF's MEASURE function frames risk measurement as an ongoing activity rather than a launch-day event [2][3], and the EU AI Act's Article 15 requires accuracy, robustness, and cybersecurity to hold across a high-risk system's lifecycle — not merely at placement on the market [6]. Both point the same direction: assurance as a continuously produced artifact. MYTHOS produces that artifact as a system output, mapped against the adversarial technique landscape that MITRE ATLAS catalogs for AI systems [4].
The invitation to evaluators is standing and deliberate: submit your own attack scenarios for live independent validation. Certification that only its author can run is not certification [VC-C].
§ 3 · IN THE STACKWhat MYTHOS Certifies
Within the portfolio, MYTHOS certifies the governance layer itself: the HCF2-SG trust thresholds and the MRM-CFS execution gates as deployed through SecureAgent ACA Tier C. Its evidence chains also feed the ZGTID consortium as governance telemetry — certified posture, aggregated privacy-preservingly across institutions [VC-C].
The certification boundary is stated as plainly as the capability: MYTHOS certifies the governance layer's resistance at the time of the run, against the families exercised. It does not certify the underlying model's accuracy, does not predict resistance to attack classes outside its six families, and is not an endorsement by MITRE, NIST, or any standards body — those bodies' frameworks are the map its results are plotted against, not the authority issuing them [VC-C].
§ 4 · QUESTIONSFrequently Asked Questions
What does MYTHOS actually certify?
MYTHOS certifies that a specific AI governance deployment resisted six distinct families of adversarial attack at a specific time, and it emits the evidence as a hash-linked chain. It does not certify the underlying AI model’s accuracy, and it is not an endorsement by any standards body — it is executable, re-runnable, third-party-verifiable proof of governance-layer resistance.
Why does hash-linking matter for certification?
Because it removes the need to trust the certifier. Each result entry cryptographically binds to its predecessor, so deleting an inconvenient failure, reordering runs, or editing a result breaks the chain visibly. A verifier needs only the chain and the sealed 20-name interface — not MYTHOS internals and not VectorCertain’s cooperation.
Can external evaluators run their own attacks?
Yes — the invitation is standing. Evaluators and standards bodies can submit their own attack scenarios for live independent validation against a governed deployment. Certification that only its author can execute is attestation wearing a costume; the framework is built for hostile verification.
