A security framework that requires continuous verification of every user, device, and request attempting to access resources, regardless of whether the request originates from inside or outside the network perimeter.

In our reference library
Zero Trust replaces the traditional castle-and-moat security model where everything inside the corporate network was trusted by default. Under Zero Trust, no entity is trusted implicitly — every access request must authenticate, authorize, and encrypt before granting access, with the same scrutiny applied to internal traffic as external traffic. The framework is built on three core principles: verify explicitly (authenticate and authorize based on all available data points), use least-privilege access (limit user access to only what is needed), and assume breach (segment access, enforce end-to-end encryption, and continuously monitor for anomalies). Zero Trust architecture became the security standard for remote and hybrid work environments where there is no clear network perimeter.
Why Zero Trust matters when choosing software
Zero Trust can affect software selection differently depending on the workflow, team size, and category. Use the definition above as the starting point, then check how the concept appears in the products you are evaluating. In practical terms, look for the controls, limits, integrations, reporting, or operating assumptions that are directly related to Zero Trust. A useful comparison should explain what the concept means, where it matters, and what evidence a buyer can verify before committing.
How to evaluate it in a real product
Start with the workflow that depends most on Zero Trust. Identify the requirement, ask the vendor for the relevant documentation or configuration details, and test the requirement with realistic sample data where possible. Then compare the result against alternatives rather than treating a marketing label as proof. Related concepts in this category include Encryption, SIEM.
