Question 1

What is SASE and why does it matter?

Accepted Answer

SASE (Secure Access Service Edge) is an architectural framework that converges wide-area networking (WAN) and network security functions into a single cloud-native platform. It matters because traditional architectures — built around a central data centre perimeter — cannot keep pace with cloud-first and remote-working environments. SASE moves security to the cloud edge, closer to where users and applications actually are.

Question 2

How is SASE different from a traditional VPN?

Accepted Answer

A VPN backhauled traffic to a central point before routing it to the internet or applications — creating latency and a bottleneck. SASE applies security policies at the cloud edge closest to the user, meaning traffic goes directly to cloud applications without backhauling. It also enforces Zero Trust policies continuously, rather than granting broad network access once a VPN tunnel is established.

Question 3

Is SASE suitable for SMEs or only enterprise?

Accepted Answer

SASE is highly relevant for SMEs with distributed workforces, cloud-first strategies or multiple office locations. It eliminates the need to buy and manage separate firewall appliances, VPN concentrators, web proxies and MPLS circuits — replacing them with a single subscription service. This can actually reduce total cost of ownership for SMEs compared to assembling point solutions.

Question 4

How does SASE relate to Zero Trust?

Accepted Answer

Zero Trust is the security philosophy — never trust implicitly, always verify. SASE is the architectural framework that operationalises Zero Trust at scale across the network. ZTNA (Zero Trust Network Access) is one of the components within a SASE platform, ensuring that access to any application is identity-verified and context-aware, rather than based on network location.

Question 5

How long does a SASE deployment take?

Accepted Answer

A phased SASE deployment typically takes 4 to 12 weeks depending on the number of sites, users and the complexity of existing network and security policies. We begin with a discovery and design phase, then migrate services in stages — typically starting with secure web gateway and ZTNA before transitioning SD-WAN and retiring legacy MPLS circuits.
