In more detail

Watching for the signs of a takeover

SaaS Alerts learns what normal looks like for each person — where they sign in from, which devices they use and how much data they usually access. It then watches for activity that doesn’t fit, such as a login from abroad minutes after one in Coventry, a new rule forwarding email outside the business, or thousands of files downloaded at once.

When something serious happens it can respond automatically — ending the session or locking the account — while alerting us to investigate and get the user safely back to work.

What it means for your business

Real-world examples

What this looks like in practice

Everyday situations businesses like yours face — and how this protection helps.

The Impossible Journey

A user signs in from Coventry at 9am and from overseas ten minutes later. The second session is ended automatically and we reset the password

The Hidden Forwarding Rule

An attacker with a stolen password sets up a rule copying every email to an outside address. The rule is flagged and removed before invoices can be intercepted

The Mass Download

Hundreds of files are suddenly downloaded from SharePoint late on a Friday night. The activity is stopped while we check whether it’s legitimate
