Top 10: Zero Trust Companies

Modern businesses face threats everywhere, not just outside their network. Zero Trust assumes breaches happen and verifies every user and device, inside or out, before granting access. 

This ‘never trust, always verify’ approach limits damage if a breach occurs. 

With remote work and cloud services, traditional network perimeters are gone. Zero Trust adapts, ensuring only authorised access to sensitive data and applications. It minimises risks from compromised accounts and insider threats, offering a more robust defense in today's complex, interconnected digital landscape. 

Here we take a look at some of the leading companies driving Zero Trust security across organisations worldwide.

CrowdStrike approaches Zero Trust from the angle of endpoint and workload security, ensuring that devices and identities are continuously verified and trustworthy before and during access.
