Whether you visit us in the Learn with Cisco booth at Cisco Live 2026 in Las Vegas or watch the action online, here's what you need to know to make the most of your week.

At EANTC 2026, Cisco N9000 switches dominated 12-vendor validation tests, including VXLAN EVPN and secure PTP/MACsec. These results prove Cisco’s open, AI-ready architecture is the industry standard for performance and multivendor integration.

Dark Reading editors reflect on two decades of dramatic change — from perimeter defense to assume-breach strategies — and warn that while AI, cloud, and COVID-19 have transformed the threat landscape, organizations are still failing at fundamental...

Understanding AI BOMs and where they fit into risk management for artificial intelligence.

CVE-2026-42897 stems from a cross-site scripting (XSS) vulnerability and can allow an attacker to compromise Outlook Web Access (OWA) mailboxes.

The now patched vulnerabilities in the rapidly growing AI agent framework allow attackers to steal credentials, escalate privileges, and maintain persistence.

Since the last update, the TeamPCP supply chain campaign produced its loudest stretch since the March Trivy disclosure: an officially confirmed Checkmarx Jenkins plugin compromise and a new self-spreading Mini Shai-Hulud worm across npm and PyPI.

The release of Shai-Hulud source code spells trouble for software developers as researchers worry the self-replicating worm could scale.

We are honored to celebrate these remarkable achievements and the trust our customers place in Cisco as their technology partner.

Security experts have long warned that insecure automatic tank gauge (ATG) systems exposed on the Internet can be tampered with by threat actors.

AI agents capable of discovering and exploiting obscure vulnerabilities are emerging alongside developers producing vast amounts of potentially flawed AI-generated code, forcing defenders to adapt accordingly.
