For CISOs

Compliance you can cryptographically prove.

You've solved encryption and access controls. But when the DPBI asks to prove consent, a database flag isn't enough. Vishwaas AI gives you cryptographic consent proof and defence-in-depth security — built for the regulator on day one.

Vishwaas AI consent ledger — an append-only, SHA-256 hash-chained list of consent events with verifiable integrity — Append-only consent ledger — every event SHA-256 hash-chained, integrity independently verifiable.

Isolation layers, fail-safe

RSA signing-key bits (HSM-held)

Consent rows a DBA can edit

RFC trusted-timestamp standard

What we ship by default.

AWS KMS HSM Integration

Consent signing keys never leave hardware. RSA-2048 keys held inside an AWS KMS HSM with per-tenant boundary.

DB-Level Append-Only Enforcement

Schema-level triggers refuse UPDATE / DELETE on consent_records. Even your DBA can't backdate a row.

SHA-256 Hash Chain

Every consent event chained — any tampering breaks the chain at the offending position and every position after.

RFC 3161 Trusted Timestamping

Third-party timestamps bind consent events to calendar time. Closes the "you could have backdated this" challenge.

Defense-in-depth tenant isolation

JWT scope + Prisma middleware + PostgreSQL Row-Level Security + Redis DB segregation — four layers, any one safely fails.

VAPT-hardened OTP flow

Redis atomic INCR counter, timing-safe comparison, IP + email rate limits. v2.7 P4B remediation applied.

When the security review lands

From threat model to signed evidence — in one session.

A board audit, a customer security questionnaire and a DPBI inquiry all ask the same thing: show me the control actually works. Vishwaas AI answers from the same dashboard your team operates.

Show the architecture

Walk the four-layer tenant isolation — JWT scope, Prisma middleware, PostgreSQL Row-Level Security, Redis segregation — any one of which fails safe.

Prove the keys never leave hardware

RSA-2048 signing keys live inside an AWS KMS HSM and never leave the boundary — demonstrate it live, don't just assert it in a datasheet.

Break the chain on purpose

Attempt an UPDATE on a consent record and watch the schema-level trigger refuse it — append-only enforcement even your DBA can't override.

Hand over verifiable evidence

Export a signed integrity report — hash-chain position, key fingerprint, RFC 3161 timestamp — that the auditor verifies without trusting Vishwaas AI.

Proof you can show an auditor

Security posture, evidenced in real time.

Every DPDP control is surfaced as a live signal — fiduciary readiness, append-only enforcement, breach posture and cross-border exposure — so a security review reads from the same dashboard your team operates.

▹Fiduciary readiness and field-mapping coverage at a glance
▹Breach posture tracked against the §8(6) 72-hour clock
▹Cross-border transfer exposure flagged per processor

Vishwaas AI Compliance Posture screen showing governance and evidence signals across the tenant — Compliance Posture — governance & evidence signals across the tenant.

Bring our cryptography to your security review.

We'll walk your team through the threat model, the four-layer isolation architecture, and the consent hash-chain verifier — live, on real data.
