Building intent-based access control without reading minds

Oct 13, 2026 By Nash Borges In Sophos
This article was first published on LinkedIn. In Minority Report, the Department of Precrime promised certainty. Three precognitives saw the future, the system picked the consensus, and police arrested people for murders they hadn't yet committed. The whole machine depended on one buried secret: sometimes the precogs disagreed, and the dissenting vision, the minority report, was quietly deleted. The system held together as long as the precogs agreed, but broke when it removed its own doubt.

Stopping attackers who want your endpoint protection to go dark

Oct 13, 2026 By Sophos In Sophos
EDR Killers let attackers blind endpoint protection before the real attack begins, and Sophos Endpoint stops them with several layers that are on by default. Most people picture a cyberattack as something loud: files encrypting, screens locking, a ransom note. But the attacks that do real damage usually start quietly. Before an attacker steals data or deploys ransomware, they try to make sure nobody is watching. That means dealing with the endpoint protection on the device first.

AI governance needs more than a policy document

Oct 13, 2026 By Bud Ellis In Sophos
AI tools have made it remarkably easy for a company to expose its own data: None of these actions seem malicious, but each one moves sensitive information somewhere the security team cannot see. This new era of "move fast and break things”, a phrase famously coined by Mark Zuckerberg in the early Facebook days, benefits attackers. Company data now flows through more places, more third parties, and more delegated credentials.

Introducing Sophos AI Defense

Oct 13, 2026 By Sophos In Sophos
Sophos AI Defense finds the AI tools employees and applications are using, including the ones security teams never approved, and enforces policy wherever they run. Every AI tool an organization can’t see is a potential gap in confidentiality, integrity, and availability. Delivered through Sophos Fusion, the AI-native cybersecurity defense system, Sophos AI Defense connects controls on the device, across the network, at sign-in, and in the browser into one line of defense, so teams can safely adopt AI faster without adding another disconnected tool to manage.
