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.

CISOs Discussed Governance, Security Operations and Cyber RiskFrom boardroom persuasion to AI-powered SOCs, ISMG's Cyber Resilience Summit Dallas gave senior security and risk leaders a playbook for the age of inevitable disruption, with sessions spanning zero trust, human risk reduction, threat preemption and governance as a foundation of resilience.
Zscaler CEO Jay Chaudhry Says New AI Frontier Models Have Yet to Boost RevenueZscaler reported strong renewal growth and rising demand for zero trust security amid AI-driven threats, but slowing new customer acquisition, sales leadership turnover and cautious expectations for Red Canary integration weighed on investor confidence.
Startup Symmetry Systems Maps Relationships Across AI, SaaS and Cloud AssetsZscaler plans to acquire San Francisco-based Symmetry Systems to unify visibility across AI models, identities, applications and datasets, helping enterprises track AI lineage, govern agentic identities and enforce granular zero trust controls across cloud and SaaS environments.
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.
Also: RSAC Speakers Warn AI Is Outpacing Security, DoD's Zero Trust Reality CheckIn this week's panel, four ISMG editors discussed growing cyber risks in healthcare following recent vendor breaches, key takeaways from RSAC Conference and whether the Pentagon's zero trust push is delivering real security benefits or just checking off boxes.
Analysts Warn Compliance Goals May Outpace Real Security OutcomesThe Pentagon's zero trust overhaul aims to unify cyber defenses, but with a small percentage of target activities reportedly complete, persistent gaps in identity, data and governance are raising doubts about whether the 2027 deadline will deliver real security gains.

Zscaler's Jay Chaudhry on Infrastructure, Agents and OversightZscaler CEO Jay Chaudhry explains why distributed infrastructure and zero trust models will shape AI security, the agent risks mirroring human threats and why strong oversight and identity validation remain essential for mission-critical applications.
CS4CA USA Summit Speaker Daryl Haegley on Zero Trust and OT VisibilityCritical infrastructure operators face constant cyber probing from state adversaries targeting energy, water and industrial systems. A U.S. Air Force cyber resiliency leader explains why zero trust, IT-OT separation and stronger anomaly detection are essential to defend mission-critical operations.
New NSA Guidance Demands Continuous Access Checks, Implementation OverhaulThe National Security Agency's new zero trust guidance instructs agencies to move beyond login-based security by continuously assessing user behavior and app-layer activity in real time, aiming to close gaps that allow post-authentication abuse and elevate federal defenses against modern threats.
Why Human-Centric Zero Trust Models Fail in a World of Autonomous AI AgentsZero trust was built for humans, not autonomous AI agents. As organizations adopt agentic AI at scale, human-centric security assumptions break down - creating a paradox between utility and least privilege that traditional zero trust models cannot resolve.
Cyber Leaders Address AI Threats, Compliance Resilience, Zero TrustFrom AI‑driven fraud schemes to tightening regulations and identity threats, ISMG's New York Fraud Prevention and Financial Cybersecurity Summits brought together CISOs, investigators and risk leaders to share practical strategies for strengthening defenses and building true resilience.
Recent Cybersecurity Conferences Highlight Resilience and Shoring Up Critical Infrastructure SystemsLearn how recent cybersecurity conferences focused on resilience and shoring up critical infrastructure systems spotlight the need for virtual segmentation, OT visibility and zero trust adoption.
CS4CA Summit Highlights How IT, OT Teams Can Come Together to Implement Zero TrustThe first step in securing OT networks is gaining full visibility into all assets, then segmenting them based on workflows rather than physical locations. Today, AI can reduce much of that workload. But IT and OT teams will need to meet in the middle - on the process boundary, not the network diagram.
In Today's Reality, Zero Trust Principles Matter, Verification Is an ImperativeThis month, a judge made history by throwing out an $8.7 million lawsuit after discovering something that had never before appeared in her courtroom: deepfake testimony. But these new legal lessons are already a reality in business: the need for trust, verification and authentic communication.
