Security Service Edge (SSE) are security solutions that aim to protect endpoints, users, and data that lie on the “edge” of a network – essentially any device that operates outside of a centralized data center. These devices, and their associated information and data, are often the most at risk from malware, security breaches, and data loss, making implementing SSE for enterprises a smart solution to prevent risk.
The solutions on this list often compromise of a range of security technologies and features, such as Cloud-Access Security Broker (CASB), Firewall-as-a-Service (FWaaS), Zero-Trust Network Access (ZTNA), and Secure Web Gateway (SWG). DLP is also often included. SSE aims to secure access to applications and servers, provide secure internet access, and secure remote access to private applications.
With the unprecedented rise in employees working from home, and more and more devices being connected to work servers, protecting your data when it rests and travels outside of your company’s centralized data center is crucial. Read on for a list of leading figures in edge security solutions to find a product that suits your business needs.
What Are Edge Security Solutions?
Secure service edge solutions (SSE solutions) fall under the category of edge security. Edge security solutions are essentially security tools that protect data that sits on the “edge” of your network–i.e., the furthest away possible from your data center while still being in your network. These devices or edges sit outside of the centralized data center and are transported outside of it also. In reality, these edges can take on various forms, from a remote worker’s laptop that only sees use outside of an office or computers and devices used in flagship offices and stores (such as the smart till for a store that’s part of a wider company).
It’s clear that the edge isn’t strictly definable, and is flexible and porous. While this is great for ease of use and practicality reasons, the edge is often a wealth of attack vectors for threat actors, meaning appropriate use and security must be adhered to to avoid breaches and attacks.

How Does SSE Work?
SSE solutions are effectively a subset of Secure Access Service Edge, which is a conglomerate of cloud-based security tools and SD-WAN capabilities, which is delivered to all users in a network no matter how close to the edge of the network they may be. SSE is SASE without the SD-WAN capabilities, meaning it is a combined solution with CASB, FWaaS, SWG, and ZTNA features. These individual tools can act independently and independently of each other to offer pervasive and adaptive cloud security.
Secure Web Gateway (SWG): A SWG acts as a barrier that prevents unauthorized traffic from accessing a network and only allows users to access secure, pre-approved websites.
Zero-Trust Network Access (ZTNA): This is a framework that determines how users log-in and when they need to manually login. It is there to restrict access and ensure applications are removed from public view, as well as enforce identity-based authentication.
Firewall-as-a-service (FWaaS): Essentially, a cloud or software-based firewall that is managed by a third party to offer robust yet flexible protection.
Cloud-Access Security Broker (CASB): A CASB protects the connection between users and their devices to cloud applications. Acting as a security checkpoint between users and cloud service providers, a CASB will secure data, information, and systems through predetermined security policies, malware prevention, and strong encryption capabilities.
