How we respond
Revoke active sessions, reset credentials, remove malicious inbox and forwarding rules, review connected apps and OAuth grants, then check sign-in and audit logs to establish what was accessed and for how long.
Account Compromise
Business Email and Microsoft 365 Compromise Help
Invoices redirected, strange logins, staff receiving mail you never sent — business email compromise is quiet, expensive and fixable. We lock the attacker out and find out what they touched.
Do this right now
- Do not act on any payment or bank-detail change request until it is verified by phone.
- Reset passwords for affected mailboxes from a clean device.
- Preserve the suspicious emails — do not delete them.
- Call us to review sign-in logs and mailbox rules.
Hardening Microsoft 365
Most compromises we see would have been stopped by a handful of settings.
- Multi-factor authentication enforced for every user
- Legacy authentication blocked
- Mail-forwarding to external addresses restricted
- Conditional access and alerting on suspicious sign-ins
- Admin accounts separated from daily-use accounts
Ongoing protection
We can take over day-to-day Microsoft 365 and endpoint management so someone is watching the alerts, not just reacting after a customer calls about a fake invoice.

Answers
Frequently Asked Questions
How do I know if our business email was hacked?
Common signs are unexpected password resets, contacts receiving mail you never sent, missing messages, sudden invoice or bank-detail change requests, and sign-ins from unfamiliar locations in your Microsoft 365 logs.
Do you support Microsoft 365 and Google Workspace?
Yes. We handle compromise response and hardening for both, though most Northeast Houston small businesses we work with run Microsoft 365.
Is this something we have to report?
It can be, depending on your industry, contracts and what data was exposed. We document the incident clearly so you and your legal or insurance advisor can make that call.
