Zscaler Internet Access - Cloud-Native Security Service Edge (SSE)
AI-powered protection for every user, device, and application - wherever work happens.
---
Overview
Enterprise security built around firewalls and perimeter defenses is no longer fit for purpose. As workloads move to the cloud and users connect from everywhere, the attack surface expands faster than legacy tools can handle. Breaches are rising despite billions spent on traditional infrastructure.
Zscaler Internet Access (ZIA) takes a fundamentally different approach. As the world's most deployed Security Service Edge (SSE) platform, ZIA replaces aging network security hardware with a cloud-native, zero trust architecture that inspects every connection, secures every user, and protects every application - without compromising performance.
As an authorised Zscaler partner, TechPower helps UK and European enterprises design, procure, and deploy ZIA as part of a broader zero trust security transformation.

Why Legacy Architectures Are Failing
Traditional firewall-centric security was built for a world where users sat inside a network perimeter. That world no longer exists.
- Cloud and SaaS adoption has dissolved the network edge
- Remote and hybrid workforces connect from outside corporate infrastructure
- Encrypted traffic (TLS/SSL) hides threats that firewalls cannot inspect at scale
- Sophisticated attackers use techniques that bypass signature-based defences
The result is a growing gap between the security tools you have invested in and the protection your organisation actually needs. ZIA closes that gap.

Use Cases
Secure Hybrid and Remote Workforces
Give employees, contractors, and third parties fast, secure access to web and SaaS applications from any location or device - without backhauling traffic through a central data centre.
Replace Branch and Edge Firewalls
Eliminate the cost and complexity of managing hardware at every site. ZIA delivers local internet breakouts with centralised policy control, reducing infrastructure overhead across distributed environments.
Protect Against Ransomware and Advanced Threats
Minimise your attack surface, stop initial compromise, prevent lateral movement, and block data exfiltration - all through a single cloud-native platform.
Enforce Compliance and Data Sovereignty
Apply localised data policies that meet regulatory requirements without sacrificing performance. Ideal for organisations operating across multiple jurisdictions.
Integrate with Your Existing Security Stack
ZIA integrates with leading SIEM, SOAR, and XDR platforms using full MITRE ATT&CK mapping and forensic-grade logging, so your SOC team gets the context needed to detect and respond faster.
