Featured Client Success Story
How NetTec Helped a Financial Services Firm Recover from a Microsoft 365 Compromise
A financial services firm engaged NetTec after a compromised Microsoft 365 account was used to send phishing emails and gain access to additional mailboxes.
NetTec immediately contained the incident, removed malicious mailbox rules, secured affected accounts, implemented organization-wide MFA, strengthened identity protections, and deployed additional Microsoft 365 security controls.
Results
✓ Organization-wide MFA implementation
✓ Microsoft Conditional Access deployment
✓ Improved visibility into account activity
✓ Reduced risk of credential-based attacks
✓ Stronger Microsoft 365 security posture
What began as a successful phishing attack became an opportunity to build a significantly stronger cybersecurity foundation.
