Cyber | Zero Trust Network Access
ZTNA
Zero Trust Network Access (ZTNA) is a modern security model built on a simple but powerful idea: trust no one by default—not even users or devices inside your network. Instead, access is granted only after verifying identity, device health, and contextual risk.
With NCL, ZTNA becomes a reality. It enforces dynamic, policy-based access controls that ensure users can only reach the resources they need, when they need them—and nothing more. It’s security that’s smart, adaptive, and built for the way we work today.

Why do businesses need Zero Trust Network Architecture (ZTNA)?
In today’s digital-first world, businesses need a smarter, more secure way to connect users to applications—wherever they are.
ZTNA delivers just that. By replacing outdated perimeter-based security with a modern, identity-driven approach, ZTNA ensures that only the right users, on trusted devices, can access specific resources—nothing more. It empowers organisations to support remote and hybrid workforces securely, reduce their attack surface, and gain real-time visibility into user activity. With ZTNA, businesses can simplify IT operations, strengthen compliance, and stay ahead of evolving cyber threats—all while delivering a seamless user experience.

Solution: AppGate SDP – Zero Trust Network Access
Secure access, simplified: AppGate SDP enables zero trust security without complexity.
AppGate SDP is a ZTNA solution that replaces outdated perimeter defences with adaptive, encrypted access based on identity, context, and device posture — not IP addresses or firewalls. It’s scalable, cloud-native, and built for today’s dynamic IT landscapes.
How AppGate SDP Works
AppGate SDP dynamically creates a one-to-one encrypted connection between verified users and approved resources. Every session is authenticated, authorised, and logged. Here’s how it enforces Zero Trust in practice:
● Policy Decision Engine: Evaluates user identity, device posture, and context in real time.
● Single Packet Authorisation (SPA): Keeps services hidden until authenticated.
● Micro-Segmentation: Limits lateral movement by isolating access to specific resources.
● Unified Policies: Apply consistent access rules across cloud, on-prem, and hybrid environments.
● API Automation: Integrates seamlessly into existing security and ITSM ecosystems.
Core Components of AppGate SDP – Zero Trust Network Access
| Component | Role |
|---|---|
| Client (Initiating Host) | Installed on user devices. Authenticates identity and device posture before connecting. |
| Controller (Policy Decision Point) | Central brain of the system. Authenticates users/devices and issues access policies based on identity and context. |
| Gateway (Policy Enforcement Point) | Applies policies in real time and only permits traffic from authenticated users. Deployed across on-premise or cloud as needed. |
| AppGate Portal | The AppGate portal provides a lightweight secure, Zero Trust access to network resources through a web browser. |
AppGate SDP offers greater flexibility, stronger on-prem support, and true Zero Trust foundations for organisations who need more than a SaaS access broker.
