About Cisco

Cisco sells security products that protect users, devices, apps, and data. Cisco describes the offering as an open, network-native platform built to handle today's threats and enable the agentic enterprise at scale.

Cisco says its security applies policy, inspection, and enforcement at every connection. Cisco also describes unified data for earlier detection and faster response, powered by AI-driven context.

For cloud protection, Cisco describes securing modern cloud and AI apps at runtime with segmentation that keeps up with change, vulnerability shielding to close the patching gap, and protection for AI workloads. Cisco Encrypted Visibility Engine (EVE) is used to find malicious flows in encrypted traffic and to decrypt without sacrificing performance. Cisco says it stops zero days using Snort ML and Talos Threat Intelligence. Cisco offers distributed, optimized enforcement with unified management across a hybrid enterprise, and the same enforcement is described for data center, cloud, campus, and IoT environments.

Cisco describes a security architecture designed to defend modern, AI-scale data centers. Cisco says the architecture closes exploit gaps, segments everywhere, and self-qualifies updates and changes.
