Your Trusted Partner in Cybersecurity Leadership
OneAccordConsulting delivers executive cybersecurity leadership for organizations that need answers today — not a roadmap to someday.
THE PROBLEM WE SOLVE
Most organizations don't have a cybersecurity leadership problem. They have a translation problem.
Security teams speak in vulnerabilities and frameworks. Boards speak in risk and revenue. Regulators speak in findings and deadlines. And somewhere in between, critical decisions stall — or worse, get made without the right context.
That gap is where breaches happen. Where audit findings pile up. Where competitive advantage disappears into remediation backlogs.We close that gap.
WHAT WE DOFractional CISO & Executive Leadership
Step into the security leadership role your organization needs — without the 18-month search or the seven-figure package. We serve as acting CISO, strategic advisor, or executive partner to CEOs, boards, and audit committees.
Governance, Risk & Compliance Advisory
Deep expertise across OCC, FDIC, FFIEC, NYDFS 500, PCI DSS 4.0, HIPAA, SOX, and SOC 2. We build GRC programs that satisfy regulators and actually reduce risk — not just check boxes.
Security Program Transformation
Operating model redesign. Control rationalization. SOC maturity. Cloud security architecture. We turn sprawling, reactive security programs into focused, measurable capabilities.
Board & Executive Enablement
Cyber risk education, tabletop exercises, and crisis simulations designed for the people who have to make the call — not the people who write the runbooks.
M&A & Transaction Advisory
Cyber due diligence for acquisitions, integration risk assessments, and post-merger security roadmaps. We quantify the risk before it becomes your problem.
Executive Cybersecurity Leadership
Immediate guidance for navigating complex regulatory environments.
HOW WE'RE DIFFERENT
We've built proprietary tools that let us move faster than traditional advisory. Our AI-powered assessment capabilities turn architecture documentation into executive-ready risk analysis in minutes — not weeks. That means we show up to the first conversation with insight, not intake forms.
But tools don't replace judgment. They accelerate it. The real difference is 30 years of knowing what matters, what doesn't, and how to get the right people aligned around the right decisions.
Our team
