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.

For workforce protection, Cisco describes secure access for humans, things, and agents with one consistent policy model. Cisco offers a cloud-native security service edge (SSE) that includes digital experience monitoring. Cisco offers a single-vendor SASE that unifies networking and security for a global workforce. Cisco offers identity security for the workforce that helps see across the entire identity ecosystem. Cisco offers multicloud NAC with zero trust, which uses intel from across the stack to enforce policy, manage endpoints, and deliver trusted access.

For threat intelligence and response, Cisco describes detecting, investigating, and responding faster with unified intelligence and operations. Cisco says this gives a team continuous visibility across users, systems, and AI agents in a single platform. Cisco describes unifying the data fabric, analytics, tooling and AI to automate the mundane, clarify the complex, and proactively mitigate risk.

Cisco also addresses agentic AI. Cisco describes safeguarding the agentic workforce against malicious attacks and data leakage. Cisco says it integrates identity, access, and behavioral controls to govern an agentic AI workforce and reduce risk. At RSAC 2026, Jeetu Patel, Cisco's President and Chief Product Officer, challenged the industry to fundamentally reimagine security.
