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.
