Secure networking

Defense starts with the network

Fuse security into the network. Stop and contain threats faster.

The new mandates for securing the AI era

Threats have evolved. Your network defense should, too.

Slow defense is no defense

Attackers traverse the network at accelerated rates. Manual response can't keep up. Inspect traffic dynamically and patch in seconds to neutralize threats before they compromise the network.

Every entity is an identity

Agents, IoT devices, and workloads now outnumber humans on the network—each one a potential entry point. Perimeter thinking leaves blind spots. Identify every entity in real time.

Quantum threats are here

Quantum threats compromise network encryption. Yesterday's defenses won't hold. Quantum-safe foundations are key to ensure data harvested today stays secure tomorrow.

Cisco secure networking: Advanced security at every layer

Fuel AI innovation, simplify operations, and future-proof your business by securing every connection point—from the data center to campus, branch, and remote environments.

Protect every flow

Secure every packet across the network with trusted infrastructure and the ability to deploy Live Protect with compensating controls at runtime.

Verify every entity

Scale intelligent identity for every device and agent on your network, enabling a dynamic zero-trust posture across campus, branch, and data center.

Prepare for the post-quantum era

Integrate advanced post-quantum encryption into Cisco networking solutions to secure sensitive data flows and ensure absolute integrity against next-generation threats.

Govern with one policy

Define policy centrally in Cisco Cloud Control and ensure consistency at every point in your network.

Build defense against AI-enabled threats

Frontier AI is accelerating innovation for defenders and adversaries alike. The question is who gets ahead of it—and how fast. See how Cisco is rising to meet the challenge.
