## About

Greymantle Risk Advisory LLC is a boutique information security and systems engineering advisory firm founded by Shane Blaufuss, CISSP. With 25+ years of hands-on experience across banking, defense, satellite systems, fintech, e-commerce, and agricultural R&D, Greymantle brings practitioner depth to engagements most firms approach with templates.

We work with growth-stage companies, SMBs in regulated industries, technical leaders who need security and systems guidance grounded in how their organization actually operates, and individuals with complex, high-stakes problems that warrant serious expertise.

Services: Security architecture and threat modeling. DevSecOps and cloud security posture (AWS, GCP, Azure). Compliance readiness across PCI-DSS, SOC 2, ISO 27001, and NIST CSF. Fractional CISO and vCISO engagements for organizations that need a real security program without full-time headcount. Retainer and fixed scope/fee services available.

Background: Shane has held senior security and systems engineering roles at First National Bank of Omaha (CERT/incident response, FBI-involved investigations), Northrop Grumman/AFWA (classified DoD weather intelligence), Raytheon (NASA/NOAA satellite telemetry), PaymentSpring/Nelnet (PCI-DSS Level 1 from scratch), The Buckle (five consecutive SOC 2 + SOX cycles, 60% reduction in audit prep time), and Corteva Agriscience (25+ AWS accounts, cloud posture from below 85% to 93%).

Every environment teaches you something different. That breadth is what the advice is built on.
