The challenge

Legacy SEG missed executive impersonation and payroll-diversion attacks.
Wire-transfer team was spending 6+ hours a day triaging false positives.
SOC had no cross-signal visibility between email, identity, and endpoint.

The solution

Deployed NUOecurity Guardian AI in inline mode across all 8 M365 tenants.
Enabled auto-remediation for BEC, credential phishing, and lookalike domains.
Integrated with existing Splunk SIEM via native XDR fabric connector.

The results

Zero successful wire fraud incidents over the following 12 months.
SOC triage load down 78% — freed 3 FTE for proactive threat hunting.
Board reporting time cut from 2 weeks to same-day with executive dashboards.

"NUOecurity gave us bank-grade email defense without a single missed business day. Guardian AI now catches BEC attempts our old gateway silently let through."
