Zero Trust is a security model that assumes no user, device or network flow should be considered trustworthy by default — even if it comes from the internal network — in contrast to the historical trusted perimeter model (firewall + VPN).
In a Zero Trust architecture, every access to a resource is verified on each request based on identity (authenticated user, MFA), context (compliant device, geolocation, risk score) and least privilege (the user has access only to what they strictly need).
The model is operationalised through ZTNA solutions (Cloudflare Zero Trust, Zscaler, Tailscale, Twingate), which gradually replace traditional VPNs in hybrid environments.
