DigiCompliance · Zero-touch privacy infrastructure

Privacy infrastructure that closes its own loops,
and signs its own proof.

Sanad sits between your systems and your regulators. Inbound webhooks accept Consent Manager events, outbound webhooks instruct vendors to erase, and a public attestation API lets them cryptographically prove it happened. Every event lands in one Ed25519-signed, hash-chained ledger — verifiable by an auditor with no login and no trust in our servers.

Built for the engineer who has to integrate it, not just the officer who has to read it.

API-first, not portal-first

Integrate once, stop babysitting it

Deletion instructions go out over signed webhooks. Proof comes back over a public Erasure Attestation API — no dashboard login, no manual upload, authenticated with a scoped attestor key your vendors control.

Cryptographic non-repudiation

Every event, signed and chained

Ed25519 signatures rooted in TPM 2.0. A per-tenant SHA-256 hash chain. CERT-In incident submissions gated by OTP-verified Maker-Checker authorization. Nothing in the ledger can be edited, backdated, or repudiated after the fact.

Zero-touch enforcement

Controls that hold without a human

RBI-grade retention locks make early deletion structurally impossible. Consent expiry runs on a cron, not a reminder email. The moment a vendor attests erasure, the chain updates itself.

How the closed loop actually closes

One consent withdrawal, four cryptographic steps, zero manual follow-up.

Step 1
Withdrawal— A data principal withdraws consent inside Sanad or your own app.
Step 2
Signed webhook out— Sanad notifies every downstream vendor holding that data — HMAC-signed delivery, SSRF-hardened, automatic retry.
Step 3
Vendor attests— The vendor's system calls Sanad's public attestation endpoint with proof of deletion, authenticated by its own attestor key — never your tenant credentials.
Step 4
Immutable proof— Sanad signs the attestation with Ed25519, chains it into the tenant's ledger, and returns a public verify URL any auditor can check independently.
