Security Service Edge (SSE)
Cloud-delivered security stack — SWG, CASB and FWaaS — enforced at the edge without touching the WAN layer. Provides TLS inspection, URL filtering, SaaS discovery and data-loss prevention for organizations that already have networking solved but need a modern security perimeter.
Overview
If you already have SD-WAN or a functional WAN and need the security half of SASE without rebuilding your network, Security Service Edge (SSE) delivers cloud-delivered security — FWaaS, SWG, CASB, ZTNA, and DLP — as a standalone service that works with your existing WAN infrastructure. Traffic from your sites, branches, and remote users reaches the nearest SSE PoP over your existing WAN or direct internet, gets inspected by the same security stack used in full SASE deployments, and reaches its destination clean.
Clevertek scopes every engagement to your environment — capacity, sites, compliance and support model — so you get a tailored plan rather than a fixed SKU. Pricing is quote-only, and our solutions architects will work through your requirements before any proposal.
Our approach
We deploy SSE for enterprises that already have a working WAN and need integrated cloud security without replacing their existing SD-WAN or routing architecture. We configure traffic steering from your existing edge devices to the nearest SSE PoP — through GRE/IPsec tunnels or direct cloud on-ramps — and define security policies that cover web filtering, CASB, ZTNA, FWaaS, and DLP from a single cloud-delivered platform. Your existing network infrastructure stays in place; the security layer is added above it.
Why work with us
Works with your existing WAN
No need to replace SD-WAN, routers, or MPLS. SSE sits above your existing network — traffic steered to SSE PoPs through simple GRE/IPsec tunnels.
Cloud-delivered security stack
FWaaS, SWG, CASB, ZTNA, and DLP delivered from globally distributed PoPs — no hardware appliances at branches, no central proxy reconfiguration.
ZTNA for application-specific access
Applications invisible to the network — users connect to specific applications through ZTNA, not to the network segment. Per-session, identity-verified, just-in-time.
CASB for SaaS governance
Shadow IT discovery, sanctioned app governance, data classification, and DLP for SaaS applications — all from the SSE platform without separate proxies.
Identity-driven policy framework
Policies based on user identity, group membership, device posture, and application — not source IP. Integrated with Azure AD, Okta, Google Workspace.
Global PoP network for low latency
50+ PoPs globally with local internet breakout — traffic reaches the nearest PoP for security inspection without long-haul backhauling.
Key benefits
What this solution delivers for your business.
Add cloud security without WAN redesign
SSE adds full security stack to your existing network. No re-engineering of the WAN, no replacement of edge devices, no migration window for network changes.
Consistent security for all users
Same policies for headquarters, branches, and remote workers — enforced from the cloud, not from per-location appliances.
Eliminate branch security appliances
Firewall, proxy, CASB, and DLP functions delivered from the SSE cloud — no appliances to deploy, patch, or refresh at branch locations.
Zero Trust for all application access
Every access request verified by identity, device posture, and context — not trusted based on network location. Internal and external users subject to the same verification.
Reduced security operations overhead
Single policy console for all security functions. Threat intelligence, policy updates, and signature deployments managed centrally — not per-appliance.

Where it helps
Real-world scenarios where this solution delivers measurable outcomes.
SD-WAN security add-on
Your SD-WAN deployment handles routing; SSE adds cloud-delivered security — SWG, CASB, ZTNA, FWaaS — without touching the SD-WAN configuration.
M&A security standardisation
Bring acquired companies onto a common security framework without redesigning their WAN. Deploy SSE with ZTNA policies and CASB for SaaS governance within days.
Remote-first workforce
Remote users connect to corporate applications through ZTNA and access the web through cloud SWG — no VPN clients, no hairpinning, consistent security regardless of connection method.
Questions buyers actually ask
How is SSE different from SASE?
SASE = SD-WAN + SSE. SSE is the security half — FWaaS, SWG, CASB, ZTNA, DLP — delivered from the cloud. You use SSE when you already have SD-WAN or a working WAN and only need the cloud security layer.
Do I need an appliance at each site?
For branch sites, traffic steering can be configured on existing SD-WAN edge devices or routers. Remote users connect through a lightweight client or clientless ZTNA browser access.
Is there latency added by cloud inspection?
SSE PoPs are globally distributed — typically 50+ locations. Added latency from security inspection is under 10ms when the nearest PoP handles the traffic.
Can I deploy SSE for some users and not others?
Yes. Deployment can be phased — start with remote users or a specific region, expand globally as the policy framework matures.
