Cryptographic Discovery & Exposure Mapping

Cryptographic discovery is the process of finding every cryptographic asset across your public internet surface — TLS certificates, SSH keys, web technologies and their associated CVEs. You can't protect what you can't see, and most organisations have significant blind spots in their cryptographic exposure.

What is cryptographic exposure mapping?

Cryptographic exposure mapping (or cryptographic risk mapping) is the practice of scanning your entire public surface and building a complete inventory of:

• TLS certificates — every HTTPS endpoint, its certificate (issuer, algorithm, key length, expiry, CN/SAN domains)
• SSH keys — every SSH server, its key fingerprint and algorithm
• Web technologies — every web stack (WordPress, Magento, Next.js, nginx, Apache) and its cryptographic dependencies
• CVEs — every known vulnerability mapped to the specific version running on each host

QROS Explore — a Shodan alternative for cryptographic discovery

QROS Explore is a public internet exposure search engine — like Shodan or Censys, but with a quantum-readiness angle that the others don't offer. For every indexed host, QROS shows:

• Open ports and services (SSH, HTTP, TLS, FTP, DNS, RDP, Modbus, MQTT)
• TLS certificate details (algorithm, key length, issuer, expiry, domains)
• CVEs by software version (from the NVD) with CVSS scores
• Quantum risk score (Shor's/Grover's vulnerability per algorithm)
• Geolocation and organisation

You can search by country, port, service, product or CVE — no login required.

Certificate discovery and PKI inventory

Certificate discovery is the automated process of finding every TLS certificate in your infrastructure — including shadow IT, forgotten servers, and third-party hosting. QROS connects to every open port and attempts a TLS handshake, indexing the certificate returned (issuer, algorithm, key length, CN/SAN domains, expiry). This creates a complete PKI inventory — your public key infrastructure, mapped and searchable.

Cryptographic dependency mapping

Every web technology has cryptographic dependencies — the TLS library it uses, the certificate algorithms it supports, the key exchange protocols it negotiates. QROS identifies the web technology stack on each host and maps these cryptographic dependencies, so you know exactly which components need updating when a vulnerability is disclosed.

Why cryptographic discovery matters

Attackers scan your public surface constantly. They know your cryptographic exposure before you do. QROS Explore gives you the same visibility — so you can find and fix weak cryptography before adversaries exploit it. Build your cryptographic inventory with QROS and achieve NIS2/DORA compliance.
