Best Zero Trust Software

Twingate is a zero trust network access product that gives users, services and AI agents identity-based access to private resources and lets a company retire its VPN. It deploys in minutes and scales to every resource, with direct-to-resource connectivity and no tunnels or bottlenecks. It is fully cloud-agnostic and designed to be virtually invisible to distributed development teams, and an intuitive admin console and a single customisable policy engine tie it to leading security and identity suites.

Access control is granular. Least privilege is enforced at every resource, database and application, device requirements can be specified precisely, and user activity is auditable with forensic detail. Twingate reaches the office network, cloud VPCs and other private resources remotely. It also includes DNS filtering, which flags, detects and blocks malicious web threats, blocks inappropriate content, blocks ads, trackers and risky domains with an extensive set of rules, and gives rich DNS log data for spotting trends and reducing risk.

Customers stress how fast Twingate goes live. One got set up in about 30 minutes, another says it was faster than any other solution they evaluated, and a DevOps engineer praises the technical documentation and infrastructure-as-code providers that make it easy to automate at any scale. Twingate also has a Kubernetes Operator and privileged access for Kubernetes. Pricing is published: a free Starter plan, Home at $15 a month, Teams at $5 per user per month and Business at $10 per user per month.

Cisco Duo is an identity and access management product built on the claim that security-first identity beats bolting authentication onto an existing directory. Duo's pitch is that attackers are evading traditional multi-factor authentication, single sign-on and identity tools, so it redefined the category around phishing-resistant MFA that needs no extra hardware. Duo can run as a full IAM solution, or broker secure access from the identity sources a company already uses, with consistent security control either way.

For zero trust programmes the useful part is how far the controls reach. The Essentials edition covers phishing-resistant MFA and single sign-on for growing teams, Advantage adds scalable identity security with identity management for every device, and Premier is positioned for organisations with the strictest safety standards, offering complete device trust. Cisco Identity Intelligence sits alongside, showing who is logging in, what is risky and what to do next, so a team can act before a threat becomes a problem. Duo also extends its zero trust approach to the agentic workforce through Agentic IAM.

Duo is aimed at teams that cannot afford friction. One customer reports getting roughly 1,000 employees onboarded and registered in under 30 days using the ready-made training and onboarding material, and Cisco cites a case study crediting Duo with reduced IT helpdesk costs. Cisco Systems was named a 2026 Customers' Choice for Access Management on Gartner Peer Insights, based on reviews submitted for Cisco Duo. Duo publishes per-user pricing, including a free edition for teams of ten or fewer.
