AI agents are already running inside your organization. They are accessing files, calling APIs, and executing multi-step workflows with no human reviewing each action. Most governance programs were not designed for this. They were built around policies for human users, controls for known data channels, and audits that happen after the fact. None of those structures were designed to govern systems that act at machine speed across every environment where data lives.

Published by the Open Worldwide Application Security Project (OWASP) in 2025, the OWASP Top 10 for Agentic Applications 2026 identifies security risks that organizations need to consider when implementing agentic artificial intelligence (AI) systems. The guide focuses on how threat actors can exploit agentic systems in new ways and on the associated risk mitigation strategies.

Each requires MCP observability that legacy DLP cannot provide.

“Just let the LLM write the SQL.” It sounds powerful. A user types a question in plain English, the model generates a query, the system runs it against the database, and the answer comes back. No SQL knowledge required. No BI tools. No waiting for the data team. It works beautifully in demos. And it is a serious engineering mistake in production. Direct SQL generation from LLMs combines two things that should never be combined: untrusted code generation and privileged execution.

GPT-5.5-Cyber is here. What it means for defenders operating at the frontier. OpenAI’s May 7 release of GPT-5.5 and the limited preview of GPT-5.5-Cyber put frontier AI in verified defenders’ hands. As a member of the Trusted Access for Cyber program, Sophos is using these models to sharpen what we already operate: an agentic SOC that resolves more than half of cases without a human, and an endpoint architecture purpose-built to stop AI-generated zero-days.

Ransomware: AI changes the writer. It doesn't change the math. Why most endpoint protection still treats ransomware as just another piece of malware, and what changes when you watch the data instead of the attacker. In 2013, CryptoLocker introduced the modern ransomware playbook. It also introduced something most of the industry has still not come to terms with: remote encryption.

For about thirty years, security has rested on the assumption that the measures guarding your systems do not have opinions. A firewall does not care how politely you ask it to open a port. An SQL filter does not weigh the context of a query before deciding whether to pass it through. An authentication check does not get distracted or talked round. You either present the right credential or you do not, and the answer is the same every time you ask.
