Meet the team.

The people on this page are the people on the call. Steadfast was founded on a simple thesis: security posture should carry diligence and accelerate exits, not just survive them. Trust is a revenue asset, and we build it like one.

Justin Graham

Cofounder and vCISO

Justin is a cofounder of Steadfast Partners and the architect of its vCISO services. He has spent two decades in healthcare and federal security, served on the HITRUST external assessor council and speaks regularly on how health tech companies pass the reviews their customers run.

Having sat on the assessor side of the table, he prepares clients for how reviewers actually test. Executives get risk in plain terms, with a dated plan and a cost.

Certifications. CCSFP, CHQP, ISO 27001 Lead Auditor. BBA in Computer Information Systems, Texas State University.

Marc Sabelli

Cofounder

Marc is a cofounder of Steadfast Partners and leads partners, business development and operations. He began as one of the original SOX auditors at PwC and has spent two decades since in cybersecurity advisory and sales leadership, including eight years focused on security and compliance for growing companies.

His rule is keep it simple and do the right thing. Clients get a reliable advisor who translates security into business decisions and keeps the audit, the platform and the detection partner working as one program.

Background. MBA, Cleveland State University. BS in Accounting, Ohio University.

Two hubs, clients national: Justin covers Texas and the central US from Austin, Marc covers the West from Southern California.
