Background for this topic.
Zero Trust is a strategic approach to cybersecurity that assumes no implicit trust is granted to access systems and data. Instead, trust must continually be verified, regardless of whether the access request originates from inside or outside of an organization's network.
In the context of information security, Zero Trust requires strict identity verification for every individual and device attempting to access resources on a private network. Policies are enforced through rigorous authentication procedures, micro-segmentation of network segments, and least privilege access controls, meaning users and devices are given the minimum access necessary to perform their functions. This model operates under the principle of "never trust, always verify," ensuring that security does not rely on static defenses but on adaptive and continuously validated trust levels.

Akamai Says Startup LayerX's Browser Telemetry Will Strengthen Access DecisionsAkamai said its proposed $205 million acquisition of LayerX will add enterprise browser security and AI usage controls to its zero trust portfolio as enterprises grapple with generative AI data exposure, autonomous AI agents and growing demand for browser-level visibility.
Guidance Warns Autonomous Systems Expand Enterprise ExposureFederal and Five Eyes cyber agencies warn that agentic AI systems - capable of autonomous action across enterprise environments - are introducing identity, visibility and control risks that could outpace existing defenses without continuous monitoring, zero trust enforcement and human oversight.
Zero Trust Is 'Essential' - But Who Pays for It?New guidance from the U.S. Cybersecurity and Infrastructure Security Agency on adapting zero trust security principles for operational technology is fine as far as it goes, but is pretty high-level and ignores or fudges a couple of key questions, say executives and experts.
A new CISA‑led guide explains how zero‑trust security can be applied to operational technology, balancing cyber defence with safety and system availability
Every security program is betting on the same assumption: once a system is connected, the problem is solved. Open a ticket, stand up a gateway, push the data through. Done
Stolen credentials remain a top breach vector, often leading to unchecked privilege escalation. Specops explains how identity-first Zero Trust limits access, enforces device trust, and blocks lateral movement. [...]
Victims don't need to match the cyber espionage group's technical sophistication, experts say. But patching and some form of zero trust are now non-negotiable.
