Post-Quantum Ready?
NIST finalized PQC standards in 2024. Is your domain prepared? Vysiro scans your domain's cryptographic setup and identifies what needs to change before quantum computers break classical encryption.
What We Scan
Three critical dimensions of post-quantum readiness
DKIM Signing Readiness (ML-DSA)
Evaluates your DKIM key sizes and signing algorithms against ML-DSA (formerly Dilithium) requirements. Identifies RSA-1024 keys that are most vulnerable to quantum attack and flags upgrade paths.
TLS Key Exchange (ML-KEM)
Analyzes your TLS configuration for ML-KEM (formerly Kyber) key encapsulation readiness. Checks whether your server supports hybrid key exchange and post-quantum cipher suites.
Certificate Algorithm Analysis
Inspects certificate chains for algorithm agility. Identifies certificates using RSA or ECDSA that will need migration paths, and checks for CA support of PQC issuance.
Why It Matters
The quantum threat timeline is shorter than most organizations assume
NIST Finalized Standards
FIPS 203 (ML-KEM), FIPS 204 (ML-DSA), and FIPS 205 (SLH-DSA) were officially published, marking the start of the post-quantum migration era.
Early Adoption Window
Organizations begin hybrid deployments. Browsers and TLS libraries add ML-KEM support. DKIM signers begin testing larger key formats.
Migration Deadlines
NIST recommends deprecating RSA-2048 for new applications. Federal agencies required to support PQC. Harvest-now-decrypt-later attacks become increasingly viable.
Cryptographically Relevant Quantum Computers
Projected timeline for quantum computers capable of breaking RSA-2048 and ECC-256. All classical public-key cryptography at risk.
Harvest Now, Decrypt Later
Adversaries are already collecting encrypted traffic today to decrypt once quantum computers become available. Data with long-term sensitivity - financial records, health data, government communications - is at risk now, not in the future.
Available on Starter+ Plans
PQC readiness assessment is included with all paid Vysiro plans. Free scans include a basic cryptographic overview, while Starter and above receive the full ML-DSA, ML-KEM, and certificate algorithm analysis.
