You can't govern what you can't see: Detecting shadow AI on your network

AI adoption inside the enterprise didn't ask for permission. It arrived through browser tabs, code editors, and meeting transcription bots, quietly stitching itself into daily workflows long before security teams could write policy around it. The result is a familiar story with a new villain, a sprawling, unmanaged attack surface that lives in your network traffic but nowhere in your asset inventory. We call it shadow AI, and it's the blind spot you didn't plan for or budget for.

The New Face of AI Risk

Cybercrime used to have a ‘"tell." It was the digital equivalent of a villain stroking their cat - clunky grammar, misspelt links and suspicious attachments that screamed ‘phishing’. But the arrival of AI has changed everything. Typos have been replaced by perfect prose. Generic lures have evolved into highly personalized attacks that mimic your internal language and align with your project timelines.

How to Discover, Monitor, and Manage Shadow AI Across the Enterprise

Shadow AI is the fastest-growing unmanaged risk surface in most organizations. Employees are adopting AI tools through browser extensions, free-tier SaaS accounts, personal logins, and embedded platform features without involving IT, security, or procurement. The result is an expanding footprint of AI systems that process corporate data, generate business outputs, and create compliance exposure while remaining invisible to the governance program responsible for managing those risks. ‍

Bringing Claude Enterprise Activity into Cato AI Security

Claude is now a part of many employees’ everyday work. But even as a sanctioned application, it creates a visibility problem for security teams. Sensitive data can move into prompts, files, projects, and conversations, and teams need a practical way to see what happened and whether it violates policy.

Cato CTRL Insights: How One Threat Actor Turned Frontier AI Into an Offensive Platform

A Russian-speaking threat actor known as “Trim” has spent the better part of 2026 systematically dismantling the guardrails on publicly available frontier AI models and rebuilding them as offensive tools. What started in March as a knowledge-sharing post on a Russian cybercrime forum detailing how to break Claude Opus into writing malware, had evolved by June into a fully productized, commercially marketed AI-powered penetration testing platform.

Top 9 AI Penetration Testing Companies for AI/ML/LLMs/MCPs

From inchoate brainstorming sessions in the halls of Dartmouth College to a panoply of funding springs and winters, AI has made its way into the tech stack of not just almost every enterprise but also every household. This, though music to the ears of an AI researcher, rewards a security professional with sweat beads. Even a single AI/ML/LLM or an MCP feature in your product evolves your attack surface, necessitating scouting for the right AI/ML/LLM/MCP penetration testing companies.

Trust Nothing: Tips to Secure AI Tools and Agents

So, you have some AI tools or are thinking about deploying them and want to know a bit about securing them. You are not alone, but there are significant challenges due to the rapidly growing capabilities of AI, and the issues around new types of vulnerabilities we may not be used to thinking of. This is a very challenging area to attempt to secure, but I hope to point you in the right direction and set you up with some resources.

When AI Agents Run Healthcare Workflows, Business Logic Becomes the New Attack Surface

Healthcare has moved well past pilot projects. AI agents now triage support tickets, draft clinical documentation, manage patient engagement, and coordinate care across systems that were never designed to talk to autonomous software. Autonomous systems can now analyze data, make decisions, trigger actions, and coordinate across clinical systems with minimal human oversight.

Identity Security for AI

What's scarier than an engineer with prod access? An agent with the same access that never sleeps, never asks, and runs a thousand sessions while you're at lunch. Last year we solved the problem of visibility in the Identity Chain, the concept is that identities are fragmented and it’s hard to get a view from Identity Providers to Infrastructure. Within a year, two things have changed. First, teams are using LLMs & Tools to perform actions on their behalf - fully delegating work to AI Agents.
