Put an unexpected sign-in in context.
Review suspicious Microsoft 365 sign-in activity alongside the mailbox changes your team is investigating.
An unfamiliar location can be a useful lead. It can also come from a VPN, mobile connection or travel. Your engineers need enough context to ask the right questions before deciding whether an account has been compromised.
Office 365 suspicious login alerts: what needs review?
Office 365 and Microsoft 365 are both terms engineers use when looking into account access. Check the account, connection and surrounding activity rather than treating the wording of an alert as a verdict.
Start with the user and the connection
Vigil Alerts brings user, IP address and location context into the review process. Use those details to check activity with the account owner and decide which events need closer attention.
Look beyond a single event
A sign-in becomes more useful to an investigation when it can be considered alongside related changes. Review inbox rules, forwarding and delegation activity affecting the same account.
Pause notifications during a known investigation
Engineers can snooze a user’s alert notifications for a period while events continue to be collected and recorded. This supports an ongoing review without losing the activity that may matter later.
Does Vigil Alerts block a sign-in?
No. The platform monitors and alerts. Your team remains responsible for any account protection or recovery action using its established tools and procedures.
