Quantum-Safe Networking on Your Existing Cisco Infrastructure

How a federal agency used Phio TX-EM to secure their network using highly resilient and adaptable quantum security

A federal agency needed to secure its network against quantum threats fast, without new hardware or budget. See how they rolled out post-quantum cryptography site by site, deploying in as little as 60 minutes per site with zero downtime for algorithm changes, as part of a phased approach that continues alongside their Cisco SD-WAN upgrade.

What’s inside

• Why the agency chose to enable PQC on existing Cisco hardware
• How Phio TX-EM adds PQC to infrastructure already in place, with no rip-and-replace
• Why the agency chose a phased, site-by-site rollout instead of a single cutover, with remaining sites continuing as part of a Cisco SD-WAN upgrade
• What the agency’s network team needed to learn, and what it didn’t

FAQ

Is post-quantum cryptography available today for Cisco networks? Yes. Phio TX is available now and works with the Cisco infrastructure you already have.How long does deployment take? A full deployment took as little as one hour per site.

Do you need to update your whole network at once? No. The agency rolled out site by site rather than in a single cutover, with additional sites continuing as part of a Cisco SD-WAN upgrade already underway.

Can you adapt your cryptography as algorithms and threats evolve? Yes. Phio TX is built for crypto-agility, so you can change algorithms as standards and threats evolve without disrupting your network.

How does this help with EO 14412 compliance? Deploying on existing hardware eased the burden of compliance by providing the agency with an expedited means for audit-ready crypto-agility.

What is Phio TX-EM? Phio TX-EM is a cryptographic management software platform that resides in a container that runs within the Cisco router’s device boundary and delivers strong symmetric keys out of band, separate from the data plane. It is FIPS 140-3 and FIPS 203 validated.
