Proof graph
One evidence model for code, dependencies, releases, deployments, customers, and approvals.
Core System
Evidence organized around decisions, not findings.
Efeeo connects release history, SBOMs, build attestations, code review provenance, deployment context, exceptions, and approvals into a proof graph that product security teams can query when the stakes are high.
Posture management tells you where you stand today. Efeeo maintains the record of what you shipped, what evidence supported it, and who owned the call.
Deterministic evaluation
Same evidence, same result. Conclusions come from cited facts and policy logic.
Human + AI provenance
See where agents authored, reviewed, tested, approved, or lacked independent review.
Independently verifiable
Tamper-evident records that customers, auditors, and regulators can verify without trusting Efeeo or your build infrastructure.
Decision method
Product-security decision patterns proven on Customer Zero and applied to your releases and PSIRT response. The reusable corpus grows with every signed disposition.
FIRST's PSIRT Services Framework requires a stakeholders-to-products/versions matrix under every service it defines. Efeeo maintains that matrix as tamper-evident, queryable evidence.
Release Assurance
Release assurance is where product security governance becomes real.
Every release is a bundle of decisions: what changed, who or what authored it, who reviewed it, what evidence exists, what exceptions were accepted, and who owns the risk. When the authors are increasingly agents, the judgment calls do not get fewer. They get faster, and they need better ground to stand on.
Independent review
Detect AI-authored changes that lack human review or security-qualified approval.
Release evidence
Bind provenance, SBOM, scans, exceptions, and approvals to the product/version record.
Exposure answers
Know which products, versions, and deployments are affected when a vulnerability lands.
Advisory-Day Runbook
A response path for the first 72 hours.
Efeeo helps teams move from advisory to supported disposition without improvising from tickets, stale SBOMs, or scattered release notes.
Match advisory to products and versions
Evaluate components, dependency paths, build provenance, and deployed release history.
Name facts, assumptions, and unknowns
Separate evidence-backed conclusions from areas requiring owner judgment or additional collection.
Draft the customer packet
Assemble advisory language, notification scope, citations, and reporting-clock status.
Route disposition for sign-off
Preserve named accountability before customers, regulators, or executives are updated.
How to start
Start with the Baseline.
The Baseline is a fixed-scope engagement: backfill your release evidence, verify it against the proof graph, replay a real advisory (Miasma or Shai-Hulud) against your own history, and validate the response path with your named owners.
Release Assurance Baseline
Backfill, verify, replay, validate. Map release evidence, AI provenance, review coverage, policy decisions, and accountable owners into the proof graph.
Managed Release Assurance
Efeeo operates the evidence graph and advisory-day mechanics as a service: intake, evaluation, packet drafting, and clock tracking, with every disposition routed to your named owners.
