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.
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.
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.
