Secure Access Service Edge In Action

How to Implement SASE in Organizations

Ever wondered if turning “Secure Access Service Edge” into your organizational mantra is as complex as its name sounds?

Steps to Implementation:

  1. Assessment Phase: First, identify the current network and security infrastructure in place. What do you have? What do you need?
  2. Select the Right Vendor: Don’t just pick any vendor; choose one that aligns with your company’s needs and has robust SASE offerings.
  3. Phased Deployment: Instead of a massive overhaul, consider a step-by-step approach. It’s like learning to swim; you don’t dive into the deep end right away!
  4. Employee Training: A tool is only as good as its user. Ensure everyone knows how to utilize SASE effectively.
  5. Continuous Monitoring: Keep an eagle eye on traffic, threats, and performance metrics.
Step Description
Assessment Phase Identify current network and security infrastructure, assessing needs and requirements.
Vendor Selection Choose a vendor that aligns with the organization’s needs and offers robust SASE solutions.
Phased Deployment Implement SASE gradually, avoiding a massive overhaul, and ensuring a smooth transition.
Employee Training Ensure all team members are proficient in utilizing SASE effectively for optimal results.
Continuous Monitoring Keep a vigilant eye on network traffic, threats, and performance metrics for ongoing success.

Considerations and Best Practices:

Integration with Existing Tools: Ensure the SASE solution can play nicely with your current tools. Additionally, Scalability is Key: Think about the future. As your organization grows, your SASE solution should grow with it. Moreover, Focus on User Experience: A slow, clunky system will find no fans among your team. Therefore, ensure your SASE solution is user-friendly.
