The Challenge#

• Microsoft 365 has 200+ security settings across 8 admin portals
• Average data breach costs $4.45M and takes 277 days to identify
• Compliance violations can result in 4% annual revenue fines (GDPR)
• 95% of breaches are caused by misconfiguration, not technology gaps
• DIY security leaves audit gaps and unprotected attack vectors
• Your team lacks time and expertise for proper implementation

Our Solution#

• Enterprise-grade security deployed in 14-21 days, not months
• Audit-ready compliance mapped to 6+ frameworks (HIPAA, ISO, GDPR)
• 500+ successful deployments with zero client breaches
• 100+ page documentation package with configuration proof
• 30-day support transition to ensure team readiness
• ROI-positive: Prevention costs less than breach recovery
