PQC Migration for Telcos

How confident can you be in your encryption if you can't see all of it?

Large telco networks run thousands of cryptographic processes across infrastructure, cloud services, legacy equipment, IoT and edge devices. Without a complete inventory of where and how encryption is deployed, you're operating blind to risk - vulnerable to weak algorithms, non-compliant configurations, and quantum threats.

Arqit Encryption Intelligence uncovers cryptographic blind spots, identifies quantum-vulnerable systems, and delivers a prioritised roadmap for remediation and post-quantum migration - aligned with NCSC guidance and regulatory timelines through 2030.

 

The Problem: Encryption Blind Spots

Encryption blind spots create risk

  • Weak or deprecated algorithms expose sensitive data to classical and quantum threats

  • Quantum-vulnerable cryptography leaves networks open to harvest now, decrypt later (HNDL) attacks

  • Thousands of cryptographic processes across multi-vendor infrastructure, cloud, legacy systems, IoT and edge devices

Operating without cryptographic visibility

  • Without full visibility, you cannot identify where encryption is deployed or which algorithms are in use
  • Multi-vendor environments and legacy systems hide cryptographic vulnerabilities
  • Migration planning is slow, risky, and expensive without a complete inventory

Regulatory Pressure

  • UK and European regulators require post-quantum cryptography migration planning by 2026, with priority system migration by 2030

  • Without cryptographic visibility, migration is slow, expensive, and exposes telcos to compliance risk and data loss

  • Non-compliant configurations fail regulatory standards and audit requirements

Solution: Encryption Intelligence

Encryption probes gather data from across the infrastructure, analyse it in place, and populate the multi-tenant centralised Encryption Intelligence platform.

Telcos gain immediate visibility into:

Risk Discovery & Assessment

  • Complete cryptographic inventory across infrastructure, cloud, legacy equipment, IoT and edge devices.
  • Identification of weak or deprecated algorithms
  • Detection of quantum-vulnerable cryptography
  • Visibility into which countries encrypted traffic traverses for compliance assurance
  • Continuous monitoring that flags newly introduced risks as networks evolve

Migration Planning & Execution

  • Prioritised risk register with practical remediation actions tailored to your environment
  • Phased roadmap toward quantum-safe encryption aligned with network investment cycles
  • Clear migration planning that identifies dependencies and system priorities
  • Avoids emergency remediation and rushed, costly upgrades
  • Expert consultancy supporting every phase from discovery through implementation

Compliance & Trust

  • Automated evidence generation for audits and regulatory reporting
  • Clear documentation of cryptographic posture meeting NCSC, NIST and DORA requirements
  • Ongoing compliance assurance as UK, US and EU post-quantum mandates take effect through 2030
  • Stronger customer trust through demonstrable security leadership and transparency
