Beyond the Protocol: Applying API Engineering Practices to MCP Servers
Cisco DevNet applies API engineering practices, such as versioning, linting, changelogs, documentation, to MCP servers with a new format: MCP Description.
A Different Road to Quantum Safety: The PPK – IPsec Series, Part 5
A second road to quantum safety: a Postquantum Preshared Key mixes an out-of-band secret into the IKE key schedule that never travels the wire, so even a classical handshake resists "harvest now, decrypt later," on gear not supporting ML-KEM.
Watch a Hybrid Post-Quantum Handshake on the Wire – IPsec Series, Part 4
We build a real hybrid IKEv2 tunnel in two Docker containers, capture the packets, and run classical versus hybrid side by side, seeing the extra round trip, ML-KEM fragmentation, and that going quantum-safe costs almost nothing.
ML-KEM vs Diffie-Hellman: The Showdown – IPsec Series, Part 3
We put Diffie-Hellman and ML-KEM side by side on size, latency, compute, and security, and land on the smartest move: a hybrid key exchange that runs both and combines their secrets, so an attacker would have to break both at once.
Harvest Now, Decrypt Later: The Threat to Key Exchange – IPsec Series, Part 2
We zoom in on key exchange and its urgent "harvest now, decrypt later" threat, where attackers record encrypted traffic today to decrypt once quantum hardware matures. Then we meet the two contenders: classical Diffie-Hellman and post-quantum ML-KEM.
Beyond CMDB Sync: Cisco Catalyst Center for ITSM Workflows
Discover how Cisco Catalyst Center 3.2.1 enhances ServiceNow CMDB integration with Granular Stack Switch Synchronization. Improve asset visibility, streamline ITSM workflows, and automate lifecycle management today.
Is Your VPN Ready for the Quantum Era? – IPsec Series, Part 1
Quantum computers will break today's crypto. We introduce the two pillars of a secure handshake, key exchange and auth, and how each faces a different quantum threat: "harvest now, decrypt later" versus the slower risk to long-lived trust anchors.
Share Your Experience: Where the Human Voice Thrives in the Age of AI
DevNet’s Share Your Experience (SYE) initiative uses your insights to drive product improvements. Through Design Thinking at Cisco Live, we turn feedback into action. Join us in building a better developer experience, one interaction at a time.
DevNet Sandbox: Building the Future of Developer Experiences
Starting August 1st, the Cisco DevNet Sandbox will go offline for a complete rebuild. We're creating a modern experience focused on AI, automation, and programmability. Stay tuned for our next-gen platform for the developer community.
