Commentary
Twenty-Two Seconds: What M-Trends 2026 Says About Attacker Speed and Defender Reality
Mandiant's M-Trends 2026 report, grounded in over 500,000 hours of incident investigations, contains several findings that should recalibrate how security teams think about detection windows, initial access economics, and the real mechanics of ransomware recovery denial. The headline statistic — 22 seconds from initial access to secondary threat group handoff — isn't the most important one.
The Agentic Attack Surface: Your AI Assistant Is the New Endpoint
Enterprise AI assistants now hold privileged access to code repositories, cloud credentials, internal APIs, and production systems. Security teams are not monitoring them. This is a structural blind spot with material consequences — and it's arriving faster than most organisations realise.
The AI Patch Wave Is Already Here -- and Defenders Are Already Behind
The NCSC warned in May that AI-accelerated vulnerability discovery would create a forced correction of technical debt. One month later, Anthropic's Project Glasswing has already found over 10,000 critical vulnerabilities in open source. The bottleneck is no longer finding bugs. It's fixing them.
The Data That Nation-States Actually Want Is Sitting in Your Document Management System
Law firms and professional services firms are among the most intelligence-rich targets in the UK economy. Understanding why clarifies the threat -- and why perimeter security alone is the wrong response.
Why Ransomware Groups Don't Die When You Arrest Their Leaders
The ransomware-as-a-service model has created a resilient criminal infrastructure that survives law enforcement actions, FBI seizures, and individual prosecutions. Understanding why is the first step to defending against it.
Nation-State Threats: What Business Leaders Get Wrong and Why It Matters
Most executives conflate nation-state cyber activity with the ransomware threat they're more familiar with. They are different in purpose, method, and the defences required. Getting this wrong shapes your entire risk posture.
