Post-Quantum
Cryptography Consultancy

Quantum computers will break RSA and ECC. The timeline is debated — the outcome is not. Nocturne Systems helps industries migrate their cryptographic infrastructure to post-quantum standards before the window closes.

"Harvest now, decrypt later" attacks are already happening. The time to migrate is now.

Who Needs This

Every industry with data worth protecting.

Financial Institutions

Banks, NBFCs, and payment processors handling sensitive transactions need cryptographic infrastructure that will survive quantum attacks — which classical RSA and ECC will not.

Healthcare & Insurance

Patient records and claims data carry lifelong sensitivity. Harvest-now-decrypt-later attacks mean data encrypted today can be cracked by quantum computers in 10 years. PQC closes that window.

Government & Regulatory

Compliance with emerging NIST PQC standards (FIPS 203/204/205) and pre-emptive hardening for national security-adjacent systems.

Enterprise Comms & PKI

Certificate authorities, VPN infrastructure, and API authentication layers are the first targets. We migrate your PKI to hybrid classical/post-quantum before the attackers arrive.
