SASE

Secure Access Service Edge

In plain language

A service that bundles network and security tools in the cloud so staff are protected wherever they work.

The metaphor

Like a security checkpoint that follows each employee wherever they go, in place of one built only at the office door.

Going deeper

How it works

  • Security checks run in the provider's cloud and not on a box in your office.
  • It combines a web filter, a cloud app filter and secure remote access.
  • It fits teams that work mostly from home or on the road.
  • Most small offices still do well with a managed firewall and a VPN.
In practice
  • A remote team of six uses it in place of an office firewall.
  • A firm with staff in three cities sets one policy for everyone.
  • A larger firm adds it when it retires its head-office network.

A question owners ask

Does a five-person office need SASE?

Rarely. Start with a managed firewall, device protection and MFA, and revisit it if your team goes fully remote.
