Axiom Sovereign delivers enterprise-grade AI governance, vCISO services, and privacy compliance to mid-market professional services firms that have historically been priced out of this level of expertise.
Axiom Sovereign was founded on a simple conviction: that mid-market professional services organizations deserve the same quality of security and privacy leadership that large enterprises access through Big 4 consulting relationships — without the six-figure engagement minimums, the rotating associate teams, and the advisory-only delivery that leaves implementation entirely to the client.
The firm was established by Cory Missimore in Severna Park, Maryland, after 17 years of building and leading information security, AI governance, and privacy programs at some of the most complex organizations in the United States — the Department of Homeland Security, the Department of Veterans Affairs, the Department of Defense, the Department of Education, and the Department of Health and Human Services. That experience, combined with enterprise technology leadership at Avanade (the Microsoft-Accenture joint venture), Baker Tilly, Bloomberg BNA, NRECA, and the American Institutes for Research, forms the practitioner foundation of Axiom Sovereign's service delivery.
The firm's name reflects its purpose. An axiom is a self-evident truth — a foundation that does not require justification. Sovereignty is the authority to govern your own affairs. Together, they define what Axiom Sovereign believes every organization should have with respect to its technology: the foundational capability to understand, control, and make deliberate decisions about the technology it depends on.
To enable mid-market professional services organizations to exercise genuine sovereignty over their technology decisions — understanding the risks they accept, governing the AI tools their staff use, protecting the sensitive data entrusted to them by clients, and meeting their regulatory obligations with confidence — without requiring Big 4 budgets or full-time security leadership to do so.
A professional services sector where security and privacy are not privileges of the enterprise, where CPA firms protecting client tax data operate with the same governance rigor as the financial institutions they serve, where law firms managing privileged communications have AI governance programs as robust as their conflict-of-interest protocols, and where mid-market organizations compete for government and enterprise contracts based on merit — not the absence of a security program.
We build and operate programs. We don't hand clients a list of recommendations and leave. Every engagement produces a functioning system, not a report about what a system should look like.
Every engagement is delivered by Cory Missimore directly — not delegated to junior staff. When you hire Axiom Sovereign, the person with 17 years of GRC experience is the person doing the work.
We evaluate every technology recommendation against sovereignty criteria: who controls it, what obligations they have, and what the organization would need to do if that vendor were restricted or failed.
We tell clients what they need to hear, not what is easiest to say. If an organization's security posture is critically inadequate, that assessment is delivered clearly. Optimism that leaves clients exposed is not a service.
Every statistic and claim we make is sourced to verifiable research. We do not use estimated or fabricated data to make our case. The risks are real enough without embellishment.
Federal-government and Big 4 quality GRC leadership, accessible to organizations that have historically been priced out of it. This is not a cost-optimization story — it is an access story.
Mid-market professional services organizations with client confidentiality obligations and no dedicated security leadership. Specifically: CPA and accounting firms (10 to 200 staff), law firms (10 to 100 attorneys), medical groups and healthcare practices, management consultancies, and NGOs managing sensitive international programs.
Federal government subcontract work through prime contractors including Leidos, Booz Allen Hamilton, SAIC, and CACI. Axiom Sovereign maintains SAM.gov registration and is positioned for subcontract engagements requiring NIST SP 800-171, CMMC, and federal privacy compliance expertise.
United States nationally, with particular density in the Mid-Atlantic region (Maryland, Virginia, DC). International engagements in the European Union (GDPR compliance), Latin America, Africa, and Central Asia through NGO and development program clients.
Cory Missimore is the founder and principal advisor of Axiom Sovereign. He holds CISSP, CISM, CDPSE, CIPP certifications and brings 17 years of GRC experience spanning federal consulting, Big 4 advisory, and enterprise technology leadership.
At Booz Allen Hamilton, he supported information security and risk management programs for the Department of Homeland Security, Department of Veterans Affairs, Department of Defense, Department of Education, and Department of Health and Human Services. At Baker Tilly, he led GRC engagements for mid-market and enterprise clients in financial services, healthcare, and government contracting. At Avanade (the Microsoft-Accenture joint venture), he led enterprise security architecture and compliance programs across large-scale Microsoft technology implementations.
He has also held GRC leadership roles at NRECA (the national trade association for electric cooperatives), Bloomberg BNA (a legal and regulatory information provider), and the American Institutes for Research (a social science research organization). This breadth of experience across sectors, regulatory frameworks, and organizational scales is the practitioner foundation that Axiom Sovereign clients access directly in every engagement.
"The organizations I've worked with throughout my career — federal agencies managing critical infrastructure, financial institutions navigating complex regulation, healthcare organizations protecting patient data — all had one thing in common: dedicated security leadership. The mid-market firms that serve their clients every day deserve the same. That's what Axiom Sovereign exists to provide."
— Cory Missimore, Founder
The concept of technology sovereignty — the strategic ability to understand and control your technology dependencies — emerged as a geopolitical and regulatory framework in Europe in the early 2020s, driven by concerns about foreign technology in critical infrastructure. Axiom Sovereign applies this framework at the organizational level: every organization, regardless of size, should understand who controls the technology it depends on, what obligations that controller has to other governments, and what would happen to its operations and data if that vendor were restricted or failed.
This thesis has proven especially relevant in the AI era. The rapid adoption of AI tools by professional services firms has created a new category of technology dependency risk — data flowing through foreign-controlled or poorly governed AI systems, professional confidentiality obligations violated by staff using unapproved tools, and regulatory exposure accumulating faster than governance programs can respond. Technology sovereignty provides the framework for addressing these risks systematically, rather than reactively.
The best introduction to what Axiom Sovereign delivers is the Technology Sovereignty Risk Assessment — a scored self-assessment that produces a baseline across AI vendor risk, regulatory exposure, and cybersecurity maturity in under 30 minutes. It is the same assessment delivered to every new engagement client.
