Access built on identity, not location

The perimeter is gone. Users work from anywhere, apps live in the cloud and the old model of trusting everything inside the network no longer reflects reality. Zero Trust and SSE replace implicit trust with continuous verification, and Secure Agility operates it for you.

Infrastructure & Security

Modern cloud environments succeed only when infrastructure is reliable, and security is built in. Our Infrastructure & Security services provide the foundation organisations need to operate confidently in Azure and AWS - combining operational excellence, governance, and security into a single, integrated capability. We help customers move from ad hoc cloud usage to stable, well-governed, and trusted platforms for critical business workloads.

WHAT IS SSE & ZERO TRUST?

Trust nothing. Verify everything.

SSE and Zero Trust are related but distinct concepts that together form the foundation of modern secure access. Here's what they mean in practice.

What is Zero Trust?

 

Zero Trust is a security model based on one principle: never trust, always verify. Rather than assuming everything inside your network is safe, Zero Trust requires every user, device and application to continuously prove they should have access, regardless of where they're connecting from. It replaces perimeter-based security with identity-based access controls that follow users wherever they work.

What is SSE (Security Service Edge)?

 

Security Service Edge (SSE) is the security layer of a SASE architecture, delivered from the cloud. It combines Zero Trust Network Access (ZTNA), Cloud Access Security Broker (CASB), Secure Web Gateway (SWG) and Firewall-as-a-Service into a single, cloud-delivered platform. SSE enforces consistent security policy for users accessing applications, regardless of whether those apps are on-premise, in Azure, or SaaS.

What is ZTNA, and how does it replace VPN?

 

Zero Trust Network Access (ZTNA) provides secure access to specific applications based on verified identity and device posture, without exposing the whole network. Unlike VPN, which grants broad network access once authenticated, ZTNA enforces least-privilege access at the application level. Users get access to what they need and nothing more. It's the practical mechanism that makes Zero Trust real for remote and hybrid workforces.

WHAT'S INCLUDED

Managed SSE capabilities across your environment

SA's Managed SSE & Zero Trust service covers the full stack of cloud-delivered security, from access control to threat inspection to compliance visibility.

Zero Trust Network Access (ZTNA)

Identity and device-verified access to internal and cloud applications, replacing legacy VPN with least-privilege, application-level controls.

 → Replace VPN with application-specific access
 → Device posture checking before access is granted
 → Consistent policy for remote, hybrid and office users
 → Continuous session monitoring and re-verification

Cloud Access Security Broker (CASB)

Identity and device-verified access to internal and cloud applications, replacing legacy VPN with least-privilege, application-level controls.

→ Shadow IT discovery and risk scoring
→ Data loss prevention for SaaS environments
→ Sanctioned app policy enforcement
→ User activity monitoring across cloud apps

Secure Web Gateway (SWG)

Inline inspection of web traffic to block malicious content, enforce acceptable use policies and prevent data exfiltration via web channels.

→ URL filtering and category-based policy
→ SSL/TLS inspection for encrypted threats
→ Malware and phishing protection inline
→ Consistent enforcement for all users, everywhere

SD-WAN Security Integration

Security-integrated SD-WAN connecting branch offices, data centres and cloud with centralised policy management and consistent threat inspection at every edge.

→ Unified policy across branch and cloud edges
→ Application-aware traffic steering with security
→ Integration with Palo Alto, Fortinet and Netskope
→ Centralised visibility across all sites

PLATFORMS WE OPERATE

Vendor-agnostic. Platform-proven.

SA operates across the leading SSE and SASE platforms, recommending the right fit for your environment rather than locking you to a single vendor.

SSE/SASE 

Netskope

Cloud-native SSE platform combining ZTNA, CASB, SWG and threat protection. SA holds Netskope Certified Cloud Security Architect accreditation.

SASE/NGFW

Palo Alto Networks

Prisma Access for cloud-delivered SASE and Prisma SD-WAN for secure branch connectivity. SA is a certified Palo Alto Networks partner.

SASE/NGFW

Fortinet

FortiSASE and FortiGate SD-WAN delivering integrated security and connectivity, particularly suited to distributed environments with on-premise infrastructure

HOW IT WORKS

From assessment to continuous enforcement.

Zero Trust is a journey, not a switch. SA delivers it in structured phases so each step builds on the last without disrupting the business.
