Exam PSE-Strata-Pro-24 Topic 2 Question 21 Discussion

SASE (Secure Access Service Edge) is a cloud-based solution that combines networking and security capabilities to address modern enterprise needs. However, there are scenarios where an on-premises solution is more appropriate.
A: High growth phase with existing and planned mergers, and with acquisitions being integrated.
This scenario typically favors a SASE solution since it provides flexible, scalable, and centralized security that is ideal for integrating newly acquired businesses.
B: Most employees and applications in close physical proximity in a geographic region.
This scenario supports the choice of an on-premises solution. When employees and applications are concentrated in a single geographic region, traditional on-premises firewalls and centralized security appliances provide cost-effective and efficient protection without the need for distributed, cloud-based infrastructure.
C: Hybrid work and cloud adoption at various locations that have different requirements per site.
This scenario aligns with a SASE solution. Hybrid work and varying site requirements are better addressed by SASE's ability to provide consistent security policies regardless of location.
D: The need to enable business to securely expand its geographical footprint.
Expanding into new geographic areas benefits from the scalability and flexibility of a SASE solution, which can deliver consistent security globally without requiring physical appliances at each location.
Key Takeaways:
* On-premises solutions are ideal for geographically concentrated networks with minimal cloud adoption.
* SASE is better suited for hybrid work, cloud adoption, and distributed networks.
