Financial Services Leader

The Challenge

A major financial institution with 50,000+ M365 users needed to strengthen their security posture before a regulatory audit. Their existing Microsoft Secure Score of 62/100 wasn't sufficient, and manual assessments were taking 120+ hours with incomplete coverage.

What We Found

  • 47 critical misconfigurations Microsoft Secure Score missed
  • 12 users with email forwarding rules to external addresses
  • 34 admin accounts without MFA enabled
  • Legacy authentication enabled for 2,400+ users

The Solution

Using our AI Correlation Engine, we identified attack paths that combined seemingly low-risk settings into critical vulnerabilities. Our prioritized remediation roadmap helped their security team focus on the highest-impact fixes first.

Patient Data Platform

The Challenge

A healthcare technology company processing PHI for 200+ hospitals needed to achieve HIPAA compliance and pass a SOC 2 Type II audit. Their existing security tools only covered Azure, leaving their M365 environment with significant blind spots.

What We Found

  • 23 SharePoint sites with unrestricted external access containing patient data
  • No DLP policies configured for PHI protection
  • Guest users with persistent access to sensitive Teams channels
  • Incomplete audit logging for compliance requirements

The Solution

Our HIPAA compliance mapping identified all gaps against the Security Rule. We provided evidence collection for their auditors and copy-paste PowerShell scripts for rapid remediation. The attack path analysis revealed how an external guest could potentially access PHI through chained misconfigurations.

"We were able to pass our SOC2 audit in half the time. The compliance mapping and evidence collection features are incredibly well thought out. They identified 23 SharePoint sites with unrestricted external access we didn't know existed."

Healthcare System

Regional Hospital Network

The Challenge

A 12-hospital healthcare network with 25,000 employees needed comprehensive visibility into their M365 security posture. Previous assessments were manual, time-consuming, and only covered a fraction of their environment. They needed a solution that could scale across their entire organization.

What We Found

  • 847 accounts without MFA—including 34 admin accounts
  • 156 mailboxes with suspicious forwarding rules
  • 67 Teams with external access to sensitive channels
  • Attack paths showing how external guests could escalate privileges

The Solution

Our attack path visualization revealed multi-hop exploit chains that traditional tools couldn't detect. The platform assessed their 25,000-user tenant in under 45 minutes, providing immediate visibility into critical gaps. Weekly automated scans now track their security posture over time.
