¶ Overview
Secure Access Service Edge (SASE) revolutionizes the approach to network security by seamlessly integrating Zero Trust principles with cloud-native architecture. This solution brief outlines how SASE provides secure Zero Trust access to private resources hosted in public clouds, including Azure, AWS, and Google Cloud, ensuring robust protection against cyber threats while optimizing performance and scalability. We also provide instructions on how to activate Zero Trust Private Access to Public Clouds with Exium.

Optimized Performance:
- Cloud-native architecture and SD-WAN capabilities enhance network performance, reducing latency and ensuring that users experience seamless and responsive access to private cloud resources.
Scalability and Flexibility:
- SASE's cloud-native design allows for dynamic scalability, accommodating changing workloads and operational needs, ensuring that the solution grows with the organization.
Simplified Management:
- SASE consolidates security and networking functions into a unified platform, simplifying management and reducing the complexity associated with securing access to private resources in public clouds.
Cost Efficiency:
- By leveraging cloud-native principles, organizations can optimize costs associated with infrastructure, maintenance, and scalability, ensuring a cost-effective solution for securing access to public cloud resources.
¶ Activating Zero Trust Access to Public Clouds
Exium provides two options for securing your private resources in the public clouds. In both cases, you will need to deploy a cyber gateway in a VM. Once you have created the VM, you can follow the instructions below based on the type of deployment you selected.
- For Zero-Trust Secure Private Access (SPA) only deployment use case, follow the instructions for single-interface CGW deployment.
- For Firewall replacement (or overlay) including Zero-Trust Secure Private Access (SPA) use case, follow the instructions for Multi interface CGW deployment.
Note: If your goal is to also secure the inside-out access when your private resources in the public cloud initiate connections to other Internet destinations, you will need to deploy a Multi-interface cyber gateway.
The picture above shows deployment architecture for the Dual LAN/ WAN (Multi-interface) deployment in Azure, AWS, Google or other clouds. The deployment architecture is similar for the single-interface deployment with the difference that for the case of single-interface, you will create a VM with a single interface and deploy the cyber gateway using the single-interface instructions provided above.
