Zero Trust verifies each access request and limits privileges, reducing lateral movement after compromise through segmentation and continuous authentication.
Search across headline titles and summaries.
Background for this topic.
Zero trust is a security architecture that grants no implicit access based on network location. Each request is evaluated using the user or workload identity, device state, requested resource, and relevant context. Its purpose is to limit the damage from stolen credentials, compromised endpoints, or malicious insiders by enforcing least privilege and restricting lateral movement. Zero trust is a design approach, not a single product or a claim that trust can be eliminated.
Effective controls include phishing-resistant multifactor authentication, strong identity and access lifecycle management, device and workload authorization, application-level segmentation, short-lived credentials, and auditable policy decisions. Policies should limit access to specific resources and actions rather than broad network zones. Poorly maintained identities, service accounts, segmentation rules, or policy exceptions can leave exploitable paths while creating false assurance; the identity and policy infrastructure itself also requires hardening, monitoring, and recovery planning.

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.
