What is Security Service Edge (SSE)?

SSE, or Security Service Edge, is a security solution that provides services to protect and secure an organization's network and data. It protects against cyber threats and attacks and ensures compliance with necessary requirements.

SSE is rapidly being adopted by organizations, realizing that traditional network security systems cannot cope with today's hybrid enterprises.

The main features of SSE include:

  • Zero Trust Network Access (ZTNA): This security model assumes that all network traffic is untrusted and requires authentication and authorization before network access is allowed.
  • Cloud Secure Web Gateway (SWG): This service provides web filtering and content inspection to protect against web-based threats and attacks.
  • Cloud Access Security Broker (CASB): This service provides security for cloud-based applications and data, including monitoring and controlling access to cloud services.
  • Firewall-as-a-Service (FWaaS): This service provides firewall capabilities to protect against network-based threats and attacks.

Security Service Edge vs. SASE: What's the difference?

SSE and SASE (Secure Access Service Edge) are security solutions that protect against cyber threats and attacks. However, SSE focuses primarily on providing security services, while SASE focuses on providing a complete suite of network services with built-in security.

SASE is a more comprehensive solution that combines the functions of a cloud SWG, CASB, FWaaS and software-defined WAN (SD-WAN) into a single, unified solution. It enables organizations to secure and optimize the delivery of applications and services across the enterprise, from the branch office to the cloud.

SASE provides a more complete suite of network services with built-in security for users and applications, and often includes SSE as part of its functionality. It allows organizations to easily manage and monitor security and network infrastructure from a single console.

How Security Service Edge helps security teams

Here are several ways SSE can help network and infrastructure security teams reduce manual tasks and improve their security.

Secure access to cloud services and internet usage

SSE uses SWG for web filtering and content inspection. It helps protect against threats and attacks based on . And it ensures that users can access only the services and websites that are necessary for their work, and blocks access to malicious websites and unwanted content.

It also uses cloud security state management (CSPM) to achieve visibility and control of cloud resources and services and identify misconfigurations and vulnerabilities that attackers can exploit. CSPM can automate the remediation of specific security issues, helping organizations maintain a secure posture in the cloud.

The combination of SWG and CSPM in SSE can provide a comprehensive security solution for cloud services and internet usage. SWG can protect against web-based threats and spam, while CSPM can detect and remediate misconfigurations and vulnerabilities in cloud services and resources. This can help organizations protect themselves from cyber threats and attacks and ensure compliance with regulatory requirements.

Threat detection and mitigation

SSE can detect and mitigate threats by providing advanced threat prevention capabilities including:

  • Cloud firewall: A cloud firewall is a security service deployed in the cloud to protect against network-based threats and attacks. It blocks unauthorized network access and inspects and filters network traffic based on predefined security rules.
  • Cloud sandbox: A cloud sandbox is a service that runs a potentially malicious file in a virtual environment to detect any malicious activity. This allows organizations to detect and prevent malware that may have escaped traditional security measures.
  • Malware : SSE can provide detection capabilities to detect and prevent malware that may have bypassed traditional security measures. This can include signature-based detection, behavior-based detection, and machine learning-based detection.
  • Content-based inspection (CBI): SSE can provide content-based inspection (CBI) capabilities to inspect and filter network traffic based on the content of the traffic. This may include inspecting files, web traffic, and email traffic to detect and prevent malicious activity.

By combining these capabilities, SSE can provide a comprehensive solution for threat detection and mitigation. This can help organizations quickly detect and respond to cyber attacks and take the necessary steps to protect their networks and data.

Securely connect remote workers

SSE can be used to connect and secure remote workers using ZTNA. It can provide remote workers with secure access to the organization's network and data, regardless of location or device type. Here are the key technologies involved:

  • Authentication: ZTNA uses multi-factor authentication (MFA) to ensure that only authorized users can access the network. MFA can involve a combination of something the user knows (such as a password or PIN), something the user has (such as a security token or a smartphone), or scanning part of the user using biometrics (such as a fingerprint fingerprint or facial recognition).
  • Authorization: ZTNA uses role-based access control (RBAC) to ensure that users can access only the resources necessary for their work. For example, in a Kubernetes environment, the Kubernetes RBAC feature can be used to define different levels of access for different groups of users and to grant specific permissions to individual users.
  • Encryption: ZTNA uses to protect data transmitted over the network. This may include encrypting network traffic and encrypting data at rest.

Identify and protect sensitive data

SSE helps identify and protect sensitive data using various data protection technologies, including:

  • Cloud Data Loss Prevention (DLP): Cloud DLP is a service that helps organizations identify and protect sensitive data. It can scan data across cloud services and infrastructure and automatically detect and classify sensitive data. Once sensitive data is detected, DLP can block, quarantine or encrypt it to protect it from unauthorized access or leakage.
  • High-performance TLS/SSL inspection: SSE can provide high performance Transport Layer Security (TLS)/Secure Sockets Layer (SSL) inspection capabilities. Enables inspection of encrypted traffic to detect and prevent data leakage, malware and other security threats.
  • Shadow IT discovery: SSE can provide shadow IT detection capabilities to detect and monitor the use of unauthorized cloud services and applications within an organization. This can help organizations identify and remediate security risks associated with the use of shadow IT.

How to choose the right SSE platform

When evaluating SSE platforms, there are several key factors to consider to ensure the platform is right for the organization's needs, including:

  • Cloud readiness: The platform should provide security services for cloud-based applications and data, including monitoring and controlling access to cloud services. This can help organizations ensure the security and compliance of their cloud environments.
  • Provide converged management and analytics in a single pane of glass: The platform should provide a converged management and analytics solution in a single window. This can help organizations manage and monitor their security and networking infrastructure from a single console.
  • Scalability: The platform should scale to meet the needs of organizations of all sizes, from small businesses to large enterprises. It should be able to integrate with other security solutions such as SIEM to provide a complete security solution.

By considering these key factors, organizations can ensure they choose the right SSE platform to meet their security and compliance needs.
