Independent. Vendor-neutral. Grounded in practice.
Edward Mayberry
Principal Security & Compliance Advisor
Brownsville Advisory LLC
Brownsville Advisory is an independent security and compliance advisory practice focused on helping organizations build the InfoSec maturity they need to compete — in regulated markets, federal contracting vehicles, and trust-dependent industries.
Our work spans four integrated domains: Security, Compliance, Privacy, and Trust. We do not sell products, represent vendors, or prescribe single-platform solutions. Our value is independent analysis, clear communication, and a practical path forward that fits the organization making the decision.
The organizations we work with are navigating real obstacles: a defense contract that requires CMMC Level 2 assessment, a compliance gap that is blocking a procurement, a security incident that revealed architectural debt, or a regulatory requirement that no one inside the organization fully understands yet.
We help them move from uncertainty to clarity — and from clarity to action. That means understanding the regulatory requirement precisely, scoping what actually applies, and producing advisory output that serves both the technical team doing the work and the leadership making the investment decision.
"Security work is not defined solely by paid engagements. High standards applied consistently — even outside formal scope — build trust, credibility, and long-term reputation capital."
Responsible disclosure, when performed ethically and constructively, strengthens the ecosystem without exploiting it. Every engagement — formal or otherwise — is an opportunity to demonstrate that security and integrity are not in conflict.
