AIS

Automated Indicator Sharing

In plain language

A free US government service that shares details of new cyber threats between organisations in real time.

The metaphor

Like a neighbourhood phone tree: when one house spots a burglar, everyone on the list hears within minutes.

How it works

  • Shares clues such as bad web addresses and file fingerprints.
  • Uses a standard format that security tools can read automatically.
  • Members both submit and receive.
  • Tools and providers often use feeds like it behind the scenes.
In practice
  • A tool blocks a web address after it appears on a shared list.
  • A provider imports threat feeds into its products.
  • A company joins to receive alerts.

A question owners ask

Does my business need to join?

Rarely directly. Security tools and providers often use such feeds for you.
