Impact // IAM Modernization

⚠ Challenge: Fragmented identity systems across platforms

Legacy MFA scattered, no SSO consolidation, passwordless policies absent.

✓ Solution: Unified zero-trust identity platform

Okta Workflows + Azure Entra ID + CATO SASE + passwordless policies.

Result: 100+ apps under SSO, 40% reduction in help desk tickets, passwordless adoption.

Impact // Automation

⚠ Challenge: Manual vulnerability tracking

Weekly reports built manually, no standardized SLAs.

✓ Solution: Custom Python automation framework

API-driven tracking with SQLite, CVE enrichment, automated KPI reports.

Result: 40% faster remediation, 50 hours/year saved, data-driven decisions.

Impact // Security Platform Modernization

⚠ Challenge: Aging security stack with manual phishing triage

Legacy XDR platform, no automated email threat response.

✓ Solution: Led platform transitions and automation upgrades

Microsoft Defender → SentinelOne XDR with SIEM integration. Added Abnormal AI for phishing automation.

Result: Reduced threat detection/remediation times, automated phishing response workflows.
