Problem Statement

Why QuantZen

TLS secures transport. QuantZen secures identity.

JWT Token Theft

Compromised bearer tokens can impersonate users across critical banking sessions.

Replay Attacks

Captured requests can be replayed to trigger unauthorized transactions.

Harvest-Now-Decrypt-Later

Sensitive traffic captured now may be decrypted later by quantum-capable adversaries.

Weak API-Layer Security

Transport security alone leaves identity and request integrity exposed at the API layer.

Section 6

Why Now

The quantum threat is accelerating, and financial data has a long exposure lifecycle.

Quantum Computing Progress

Capability milestones are accelerating faster than enterprise migration cycles.

RSA Risk Timeline

Long-lived key material and archived traffic face growing exposure windows.

RBI Warning Signals

Regulatory expectations are moving toward stronger cryptographic postures.

Stored Financial Data Threat

Captured payment and identity data remains vulnerable for future decryption attempts.

Section 7

Benefits
