Apps, Networks, And Legacy Systems In The Quantum Crosshairs: A CISO's POV
F5, Wednesday, August 6th, 2025
As we've covered in the first blog posts in this series, quantum computing capable of breaking today's standard encryption-so-called "Q-Day"-remains a question of when, not if.
The timeline is uncertain, but the implications are immediate, especially due to "harvest now, decrypt later" risks: Adversaries can collect encrypted data today and decrypt it once quantum technologies are viable.
Many organizations must protect sensitive data well beyond conventional risk-planning windows. While new post-quantum cryptographic standards have been ratified and some application delivery controllers (ADCs) and content delivery networks (CDNs) now offer hybrid protections, the challenge is urgent: Accumulated technical debt across legacy systems will soon demand attention, and pressure from regulators and stakeholders is rising.
