## Security Services Edge (SSE)

The security services edge (SSE) is an emerging cybersecurity concept Gartner introduced in its [2021 Roadmap for SASE Convergence](https://start.paloaltonetworks.com/gartner-report-roadmap-for-sase-convergence.html) report. According to Gartner, SSE is a collection of integrated, cloud-centric security capabilities that facilitates safe access to websites, software-as-a-service (SaaS) applications and private applications. Specifically, SSE-related security capabilities include:

* [Zero Trust Network Access](https://www.paloaltonetworks.com/sase/ztna?ts=markdown) (ZTNA)
* [Cloud secure web gateway](https://www.paloaltonetworks.com/sase/secure-web-gateway?ts=markdown) (SWG)
* [Cloud access security broker](https://www.paloaltonetworks.com/sase/next-gen-casb?ts=markdown) (CASB)
* [Firewall-as-a-service](https://www.paloaltonetworks.com/cyberpedia/what-is-firewall-as-a-service?ts=markdown) (FWaaS)

## Why SSE is Important?

A comprehensive SSE solution provides organizations with the full set of security technologies they need to provide employees, trusted partners and contractors secure remote access to applications, data, tools and other corporate resources, and monitor and track behavior once users access the network. As the hybrid workforce expands, securing those remote and mobile users, and the data and apps they access remain protected.

## What is the Difference between SASE and SSE?

SSE provides the security service elements of a comprehensive SASE (pronounced "sassy") strategy. In particular, SSE delivers access control, threat protection, data security, security monitoring and acceptable use control functionality into a single cloud-delivered solution. SSE combined with SD-WAN forms a comprehensive SASE platform, providing monitoring and policy enforcement with integrated network controls and application APIs augmented by endpoint-based controls.

[SASE](https://www.paloaltonetworks.com/cyberpedia/what-is-sase?ts=markdown) is a cybersecurity concept Gartner coined in 2019. SASE is the convergence of software-defined wide area networking or [SD-WAN](https://www.paloaltonetworks.com/cyberpedia/what-is-sd-wan?ts=markdown), and network security services like CASB, FWaaS and ZTNA into a single, cloud-delivered service model.

According to Gartner, "SASE capabilities are delivered as a service based upon the identity of the entity, real-time context, enterprise security/compliance policies and continuous assessment of risk/trust throughout the sessions. Identities of entities can be associated with people, groups of people (branch offices), devices, applications, services, IoT systems or edge computing locations."

With the common framework a [SASE](https://start.paloaltonetworks.com/sase-4-dummies.html) architecture provides, organizations can simplify management, get consistent visibility and maximize protections for users, devices, applications and data, no matter their location.

## SSE Core Capabilities

A SSE solution requires these four fundamental security capabilities.

### Zero Trust Network Access (ZTNA)

[Zero Trust Network Access](https://www.paloaltonetworks.com/cyberpedia/what-is-zero-trust-network-access-ztna?ts=markdown) (ZTNA) is a category of technologies that provides [secure remote access](https://www.paloaltonetworks.com/cyberpedia/secure-remote-access-understand-how-to-protect-remote-employees?ts=markdown) to applications and services based on defined access control policies. Unlike [virtual private networks](https://www.paloaltonetworks.com/cyberpedia/what-is-a-vpn?ts=markdown) (VPNs), which grant complete access to a LAN, ZTNA solutions default to deny, providing only the access to services the user has been explicitly granted.

When looking at the full capability set that comprises a comprehensive SSE strategy, [ZTNA](https://www.paloaltonetworks.com/blog/2021/06/why-hackers-like-your-remote-access/?ts=markdown) provides a multi-layered, remote-access, security approach that provides redundant layers of inspection and enforcement, specifically:

* Centralized Visibility and Control: Know who's accessing your data, where it's stored, and level of sensitivity -- and log network traffic where you can.
* Identity-Based Authentication: ZTNA technologies provide users with precise least-privileged access based on fully customizable authentication methods. Even after access has been granted, network security professionals can monitor user behaviors for malicious activity and signs of credential theft, malware and data loss.
* Uniform Security Policies: Enforce security policies on all corporate-owned and third-party applications regardless of where the data resides.
* Granular, Role-Based Access: Only give a user access to the data they absolutely need for their job. Restrict access based on the type of device and location used to connect.
* Post-Connect Threat Monitoring: If an attacker is still able to access the organizational network, ZTNA capabilities are still working and can detect an attacker based on their network activity.

![SSE uses ZTNA capabilities to provide users secure remote access to network resources and monitor network behavior.](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/sse/sse-01.png)

### Secure Web Gateway (SWG)

A [secure web gateway (SWG)](https://www.paloaltonetworks.com/cyberpedia/what-is-secure-web-gateway?ts=markdown) protects users from web-based threats in addition to applying and enforcing corporate acceptable use policies. Instead of connecting directly to a website, a user accesses the SWG, which is then responsible for connecting the user to the desired website and performing functions such as URL filtering, web visibility, malicious content inspection, web access controls and other security measures.

SWGs are an important part of a comprehensive SSE strategy as they provide users secure internet access when they are disconnected from the [business VPN](https://www.paloaltonetworks.com/cyberpedia/what-is-a-business-vpn-understand-its-uses-and-limitations?ts=markdown). In addition, SWGs enable organizations to:

* Block access to inappropriate websites or content based on acceptable use policies
* Enforce their security policies to make internet access safer
* Help protect data against unauthorized transfer

![SSE uses SWG capabilities to provide users secure internet access when they are disconnected from the business VPN.](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/sse/sse-02.png)

### Cloud Access Security Broker (CASB)

[CASBs](https://www.paloaltonetworks.com/cyberpedia/what-is-the-difference-between-a-traditional-casb-and-an-next-generation-casb?ts=markdown) help organizations discover where their data is across multiple software-as-a-service (SaaS) applications and when it's in motion across cloud environments, on-prem data centers or accessed by mobile workers. A CASB also enforces an organization's security, governance and compliance policies allowing authorized users to access and consume cloud resources while enabling organizations to effectively and consistently protect their data across multiple locations. There are two types of CASBs available: traditional CASBs and integrated CASBs.

An effective SSE strategy uses an integrated CASB to help organizations keep pace with the SaaS explosion. An integrated CASB uses an in-line security mechanism to automatically discover and control all SaaS risks with existing SaaS applications and the thousands of emerging ones. It also has an API-based security mechanism to scan SaaS applications for sensitive data, malware and policy violations while maintaining compliance and preventing threats in real time without dependence on third-party tools.

![SSE uses integrated CASB to discover and control all risks with thousands of existing and emerging SaaS applications.](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/sse/sse-03.png)

### Firewall-as-a-Service (FWaaS)

FWaaS enables firewalls to be delivered as part of a company's cloud infrastructure to protect cloud-based data and applications.

An SSE strategy uses FWaaS capabilities to enable organizations to aggregate traffic from multiple sources -- whether from on-site data centers, branch offices, mobile users or cloud infrastructure. It also provides consistent application and security enforcement of policies across all locations and users while giving complete network visibility and control without deploying physical appliances.

![SSE uses FWaaS to aggregate traffic from multiple sources, whether on-premises or in the cloud.](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/sse/sse-04.png)

## SSE Use Cases \& Benefits

### Secure Access

With SSE, utilizing a SWG helps to enforce internet access policy control no matter where users are or what data or apps they are accessing. SWGs are an important part of a comprehensive SSE strategy as they provide users secure internet access when they are disconnected from the [business VPN](https://www.paloaltonetworks.com/cyberpedia/what-is-a-business-vpn-understand-its-uses-and-limitations?ts=markdown). In addition, SWGs enable organizations to:

* Block access to inappropriate websites or content based on acceptable use policies
* Enforce their security policies to make internet access safer
* Help protect data against unauthorized transfer

### Better Security

Protecting users and apps is done through CASBs, through inspection, classification, and quarantining malware before the damage is done. An effective SSE strategy uses an integrated CASB to help organizations keep pace with the SaaS explosion.

### Visibility \& Control

ZTNA 2.0 provides visibility and control over what users are accessing as well as limits exposure by enforcing application-level as opposed to network-level access. ZTNA 2.0 delivers:

* True least-privileged access
* Continuous trust verification
* Continuous security inspection
* Protect all data
* Secure all apps

## SSE Deployment \& Solutions

Organizations can approach the design and deployment of an effective SSE in two ways.

1. Organizations can evaluate separate vendors for each required security technology set and then use internal or third-party resources to knit those capabilities together for a consolidated SSE solution.
   
   While this approach may provide an organization with their favorite capabilities or functionality across the various requirements, it also opens organizations up to a significant integration investment -- both at the time of deployment and long term. This approach also requires substantial management and monitoring to ensure all products and services continue to work together as a unified platform, in addition to managing multiple vendor relationships and their various SLAs.

2. Organizations can evaluate vendors that provide comprehensive security platforms with each of the necessary SSE capabilities -- FWaaS, CASB, SWG, and ZTNA -- already integrated. This approach immediately eliminates the management and integration headaches associated with the multi-vendor approach. It also simplifies troubleshooting and system maintenance needs throughout the system life cycle.

## Security Service Edge (SSE) FAQs

### How does Security Service Edge (SSE) differ from Secure Access Service Edge (SASE)?

Security Service Edge (SSE) is a Secure Access Service Edge (SASE) component. While SASE combines network and security services, SSE focuses specifically on security. SSE includes features like secure web gateways (SWG), cloud access security brokers (CASB), and zero trust network access (ZTNA), but it does not include the network-side components of SASE, such as SD-WAN.

### What are the key components of Security Service Edge (SSE)?

The key components of SSE are Secure Web Gateway (SWG), which protects against web-based threats; Cloud Access Security Broker (CASB), which secures access to cloud services; and Zero Trust Network Access (ZTNA), which ensures secure access to applications based on identity and context.

### Why is Security Service Edge (SSE) important for organizations?

SSE is important for organizations because it provides a comprehensive security framework that protects against threats in a cloud-centric environment. It enables secure access to the internet, SaaS applications, and private applications while reducing complexity and providing consistent security policies across all user locations.

### How does SSE enhance Zero Trust security?

SSE enhances Zero Trust security by verifying user identity, device security, and context before granting access to applications or data. It continuously monitors and re-evaluates trust, ensuring that users only have access privileges and that all network traffic is inspected for malicious activity, regardless of location.

### What should organizations consider when implementing SSE?

When implementing SSE, organizations should consider their existing security infrastructure, the specific security needs of their remote and hybrid workforce, and the compatibility of SSE solutions with their current cloud services. They should also look for solutions offering comprehensive threat protection, scalability, and integration capabilities to ensure a smooth deployment.
