Post-quantum cryptography (PQC) solutions

PQC readiness is the ability to protect applications, APIs, and sensitive data against quantum-enabled attacks while meeting emerging cryptographic mandates. The urgency is two-fold: adversaries are actively executing harvest now, decrypt later (HNDL) attacks against long-lived data today, while non-negotiable transition timelines—such as NSA CNSA 2.0 milestones—are already locking in. Because cryptographic migration across enterprise infrastructure takes years, organizations can’t afford to wait for audit deadlines or ecosystem enforcement before taking action.

For security and platform teams, true PQC readiness means discovering where encryption terminates, enforcing ratified NIST standards, and establishing crypto-agile controls across hybrid, multicloud, and legacy architectures. The F5 Application Delivery and Security Platform (ADSP) operationalizes this transition at the perimeter, centralizing TLS termination, visibility, and cryptographic policy enforcement with full-proxy control—without requiring backend code refactoring or disrupting application uptime.

Crypto-agility is the ability to rapidly adopt, update, and roll back cryptographic algorithms without application changes or service disruption. It is essential for PQC because standards are still evolving and no single post-quantum algorithm will be permanent. SecOps teams must support hybrid cryptography (classical + PQC), test client compatibility, and respond quickly as guidance from bodies like the U.S. National Institute of Standards and Technology (NIST) evolve. F5 delivers crypto-agility allowing teams to deploy PQC safely today and adapt continuously as the standards and threat landscape change.

Yes—PQC can be implemented without modifying legacy applications or constrained Internet of Things (IoT) and Operational Technology (OT) endpoints. The key is enforcing quantum-safe cryptography at the infrastructure layer where encryption terminates. With F5 Application Delivery and Security Platform (ADSP), PQC is applied at the application delivery and security tier, enabling legacy apps, APIs, and IoT and OT devices to benefit from quantum-safe encryption even if they cannot be upgraded. Hybrid cipher support ensures backward compatibility, while centralized policy allows SecOps teams to control exposure, manage risk, and incrementally expand PQC coverage across mixed environments without breaking production traffic.

A hybrid implementation strategy combines classical encryption with post-quantum algorithms during the transition period. This approach preserves compatibility with existing clients while introducing quantum-safe protection where supported. For SecOps teams, hybrid deployment enables controlled testing, telemetry-driven expansion, and automatic fallback to prevent outages or performance regressions. F5 supports hybrid PQC at scale through per-application TLS policies, VIP-level enforcement, and centralized observability—allowing organizations to migrate incrementally, reduce risk, and maintain service continuity while progressing toward full PQC readiness.

Organizations in the financial services and healthcare industries should prioritize PQC migration based on data longevity, regulatory exposure, and breach impact. Long-lived data—such as financial records, PII, PHI, and transaction histories—is especially vulnerable to harvest now, decrypt later attacks. SecOps teams should first protect external-facing apps, APIs, VPNs, and east-west traffic carrying sensitive data. F5 ADSP enables these industries to enforce quantum-safe encryption consistently across hybrid environments, meet compliance obligations, and reduce long-term risk without disruptive architecture changes or operational downtime.
