Services / Zero Trust & ZTNA
Never trust by location. Always verify identity.
Traditional perimeter-based security is no longer enough for modern hybrid and cloud-first organisations. Zero Trust treats every request as untrusted until it is verified.
From network access to application access
Access decisions based on who, what and how, not where.
We help organisations move away from implicit network trust towards identity-based, application-specific access. Access decisions are based on user identity, device posture, application context and security policy, not simply network location.
In practice that means Zscaler Private Access for private applications, Zscaler Internet Access for internet and SaaS traffic, and identity providers such as Microsoft Entra ID feeding every decision.
Zero Trust & ZTNA services
Zero Trust Security & Secure Private Access
We design, deploy and manage Zero Trust Network Access (ZTNA) solutions that give users secure, identity-based access to private applications without exposing internal networks.
- Zscaler Private Access (ZPA) architecture, deployment and administration
- Application segmentation, segment groups and server groups
- App Connectors, Service Edges and private application connectivity
- Least-privilege access and posture-based security policies
- Browser-based access and Zscaler Client Connector forwarding policies
- Application access troubleshooting, performance optimisation and policy enforcement
Our Zero Trust principles
Four principles behind every access decision.
Every request is checked against identity, device posture, application context and security policy before access is granted.
Verify explicitly
Authenticate and authorise access using identity, device posture and relevant contextual information.
Enforce least privilege
Grant users access only to the applications and resources required for their roles.
Reduce attack surface
Minimise unnecessary network exposure through application segmentation and secure access controls.
Monitor and optimise
Continuously assess access policies, security events, connectivity and infrastructure performance.
What changes
Perimeter security versus Zero Trust access.
Area
Traditional perimeter
Zero Trust
- Trust model
- Traditional perimeter: Users inside the network perimeter are trusted by default.
- Zero Trust: No user or device is trusted until identity, posture and context are verified.
- Access scope
- Traditional perimeter: VPN places users on the network with broad lateral reach.
- Zero Trust: Users connect only to the specific applications their role requires.
- Exposure
- Traditional perimeter: Inbound listeners and public IPs expose internal services.
- Zero Trust: Applications stay hidden behind outbound-only App Connectors.
- Policy
- Traditional perimeter: Static rules based on IP address and network location.
- Zero Trust: Dynamic policy based on identity attributes, groups and device posture.
