Create your vault. Start signing evidence today.

The system of record for engineering truth — cryptographically signed, deterministic audit evidence, generated automatically.

Connect your source control and one signal source. Define your service zones — one per service you want Déjà to watch. Déjà attributes your next incident to the causal change using deterministic AST analysis and eight weighted scoring factors (W1–W8), then issues an Ed25519-signed receipt — written to an immutable, append-only ledger and scoped to whichever framework your vault is mapped to. Built for Heads of Risk, CISOs, and audit-firm technologists at firms operating under SOC 2 Type II, ISO 27001, NYDFS Part 500, DORA, or SR 11-7 — verifiable offline by firms such as KPMG, Deloitte, EY, PwC, BDO, Grant Thornton, or any independent firm. No trace IDs, no LLM, no probabilistic guessing, no configuration wizard that outlives the trial.

First signed receipt typically within an hour of integration setup
Connect source control, connect one signal source, trigger a test signal. The vault produces its first cryptographically signed Attribution Receipt — with a Live Verifier experience for auditors via dsr-verifier-cli. Independent Ed25519 signature verification, offline, on your audit firm's machine. No Déjà account required to verify. No source code access required. The Zero-Trust principle: receipts are independently verifiable; no implicit trust required between Déjà, the customer, or the audit firm.
Scoped to your compliance footprint
Map your vault to SOC 2 Type II, ISO 27001, NYDFS Part 500, DORA, SR 11-7, or any combination. Receipts issue framework-agnostic; engagement scope projects them onto the framework your audit firm requires. One substrate, every framework.
No credit card, no contract
Trial vaults are fully featured. Convert when you're ready — we'll upgrade your vault to production, bound to your legal entity. Until then, nothing to unwind. Auditor seats are unlimited at every tier — including trial.

What you stop doing

Based on Déjà's conversations with regulated-firm engineering teams, audit prep can consume multiple FTE-weeks per cycle reconstructing evidence — searching Slack for incident context, screenshotting Jira tickets, copying deployment logs into spreadsheets. Déjà eliminates the category. Zero-click compliance · background webhook interception on every pull_request.merged event · no manual screenshotting.

About trial receipts
Trial receipts are cryptographically distinct from production receipts. They're functionally identical — same attribution, same delivery, same DSR/1.0 verification — but signed with a trial key and clearly watermarked. Not valid as audit evidence. Production receipts are signed when you convert. What's the difference? →
