Interview question · Network Security & Protocols

What are SASE and SSE, what does each component enforce, and what do you trust when your security stack moves to a vendor's cloud edge?

SASE is the firewall, proxy and access gateway moved into a provider's network so they sit in front of users wherever they are. The interview is about what each piece inspects, and what you hand the provider in exchange.

What if · the follow-ups in this answer

The answer works through 4 follow-ups like an interviewer would

A company with mostly remote staff is replacing its data-centre proxies and VPN with an SSE service. The legal team asks what the provider will see, and IT asks what breaks.

  1. What will the provider see?
  2. What will break?
  3. How do private internal apps stay reachable without the VPN?
  4. What design points do you put in the rollout plan?

Each rung has a nudge, a model answer, the principle that carries over and the weak answer to avoid. Premium opens every answer and ladder.
