Zero trust

What is zero trust?

Zero trust is a security framework based on the principle of “never trust, always verify.” Unlike traditional models that assume everything inside a network is safe, zero trust treats every user, device, and application as potentially untrusted — even inside a secured network, requiring continuous verification before granting access to resources.

How zero trust works

Zero trust uses strict identity and access controls combined with continuous monitoring. Key components include:

• Strong authentication: Multifactor authentication (MFA) to verify user identity.

• Least privilege access: Users only get the minimum permissions needed for their role.

• Micro-segmentation: Breaking networks into smaller zones to limit lateral movement.

• Continuous monitoring: Ongoing validation of user behavior and device health.

Rather than relying on a secured perimeter, zero trust assumes threats can exist anywhere, inside or outside the network.

Why zero trust is important

As organizations adopt cloud services and remote work, the traditional network perimeter no longer exists. Zero trust helps:

• Reduce breach risk: By limiting access and verifying every request.

• Protect sensitive data: Even if attackers compromise one account, they can’t move freely.

• Support compliance: Meets modern security standards for data protection.

Zero trust is now considered a best practice for modern cybersecurity strategies.
