Cryptographic Risk Management

Cryptographic risk is the exposure an organisation faces from weak, deprecated, or misconfigured cryptography across its entire digital estate — from TLS certificates on public-facing servers to SSH keys, code-signing certs, and internal PKI. Most organisations don't know where their cryptography is, what algorithms it uses, or when it expires.

What is cryptographic risk?

Cryptographic risk management encompasses three dimensions:

• Algorithmic risk — RSA-1024, 3DES, SHA-1 and other deprecated algorithms that can be broken by classical or quantum computers.
• Operational risk — expired certificates, weak key lengths, self-signed certs on production systems, and unmanaged SSH keys.
• Quantum risk — Shor's algorithm breaks RSA and ECC once a sufficiently large quantum computer arrives. Organisations need to assess their quantum readiness before that day.

Crypto agility and cryptographic governance

Crypto agility is the ability to rapidly swap cryptographic algorithms and keys across your infrastructure without breaking systems. Cryptographic governance is the framework that ensures every cryptographic asset is inventoried, assessed, and replaced before it becomes a liability. QROS provides the inventory and visibility needed to achieve both.

How QROS manages cryptographic risk

QROS scans every public-facing host — open ports, TLS certificates, SSH banners, web technologies — and maps the cryptographic posture of your entire internet exposure. For each host, QROS reports:

• Every TLS certificate (issuer, expiry, key type, key length, CN/SAN domains)
• SSH server key fingerprints and algorithms
• Web technology stack and its cryptographic dependencies
• CVEs by version (from the NVD) with CVSS scores and remediation advice
• A composite risk score (0–100) blending algorithm, key-length and quantum exposure

QROS then generates a cryptographic inventory and a prioritised quantum-readiness roadmap so you can migrate to post-quantum cryptography (PQC) before your adversaries can break your keys.

Cryptographic lifecycle management

Cryptographic lifecycle management is the end-to-end process of discovering, assessing, deploying, monitoring, and retiring cryptographic assets. QROS automates the discovery and assessment phases — continuously scanning your public surface. This is the foundation of NIS2 and DORA compliance.

Cryptographic risk and compliance

NIS2, DORA and the EU Cyber Resilience Act increasingly require organisations to demonstrate cryptographic governance — knowing what crypto you have, whether it's safe, and when to replace it. QROS provides the evidence base for cryptographic compliance with these frameworks.
