Enhancing Web Security and Remote Access with SASE
The Challenges
A customer faced challenges with managing remote users in a hybrid work environment, where applications were hosted in the cloud. Their existing setup involved a traditional on-premises proxy, which backhauled all internet traffic to the headquarters (HO), and a traditional VPN for remote resource access. This approach led to inefficiencies, high latency, and complex management.
Our Solution
To address these challenges, we proposed implementing a Secure Access Service Edge (SASE) solution. This modern approach integrates multiple security modules into a cohesive platform, offering scalability, ease of management, and improved performance. Our proposed SASE solution included:
Secure Web Gateway (SWG)
Provides robust protection against online threats and enforces security policies for internet traffic without the need for backhauling.
Network Private Access (NPA)
Ensures secure remote access to internal resources with policies based on user roles, specific ports, and machine posture checks.
Cloud Access Security Broker (CASB)
Offers granular control and visibility over SaaS applications such as OneDrive, and helps prevent sensitive data exposure.
Web Data Loss Prevention (DLP)
Monitors and protects sensitive information from being leaked through web-based interactions.
Implementation
We deployed a unified agent for all users, which redirected traffic to the SASE cloud regardless of their internet connection. This agent supported secure internet access, private network access, and web DLP functionalities. Users connected to the nearest data center of the SASE vendor for efficient internet breakout, while private access was controlled based on user roles and specific resource allocations.
The Results
- Secure Internet Access: Users accessed the internet securely with SSL interception, eliminating the need for traffic backhauling to the HO.
- Enhanced Visibility and Control: The integrated CASB provided deep visibility and control over SaaS applications and cloud resources, consolidating management in a single console.
- Efficient Agent Management: The single agent approach reduced the load on endpoints, streamlining management and improving performance.
- Scalability and Flexibility: The SASE platform allowed for easy addition of new security solutions and policies, ensuring the system could grow and adapt to future needs.
Conclusion
The implementation of the SASE solution transformed the customer’s web security and remote access capabilities. By moving away from traditional proxy and VPN setups, the customer achieved secure, scalable, and manageable access to internet and cloud resources. The unified platform provided enhanced security, operational efficiency, and a single pane of glass for comprehensive oversight and control.
