Cybersecurity Listings

The listings compiled on this directory surface cybersecurity firms, practitioners, and service categories operating across the United States, organized by geographic footprint, specialization, and regulatory alignment. Each entry reflects publicly available information drawn from state registrations, federal contractor databases, and professional certification bodies. Understanding how these entries are structured — and what they do and do not represent — is essential before drawing operational or procurement conclusions from any record shown. For broader context on why a structured cybersecurity directory serves a compliance-adjacent function, see Cybersecurity Directory Purpose and Scope.

Geographic Distribution

Cybersecurity practice in the United States does not distribute evenly. Concentration follows federal contracting corridors, state regulatory density, and the presence of research universities with active CISA-recognized academic programs. The densest clusters appear in the National Capital Region (Virginia, Maryland, and the District of Columbia), California's Bay Area, and the Texas metropolitan corridor anchoring Austin, Dallas, and San Antonio.

State-level regulatory divergence shapes which providers operate in which markets. California's CPPA (California Privacy Protection Agency) and New York's NYDFS Cybersecurity Regulation (23 NYCRR Part 500) impose distinct audit and incident-reporting obligations that favor locally credentialed or regionally experienced firms. Florida's Digital Bill of Rights, effective July 2023, added a 14th state-level consumer data framework with enforcement teeth, pushing compliance-focused providers into that market.

Federal footprint matters separately from state footprint. Firms holding a FedRAMP authorization or a DoD CMMC (Cybersecurity Maturity Model Certification) Level 2 or Level 3 assessment may operate across all 50 states under those federal frameworks regardless of individual state licensing requirements, because federal contractor eligibility derives from federal agency approval, not state licensure.

Listings are tagged by primary operational state, secondary states where documented service delivery exists, and a federal-scope flag for firms with active FedRAMP or CMMC status.

How to Read an Entry

Each directory entry follows a fixed schema. The fields below appear in the order rendered:

1. Entity name — Legal registered name as filed with the applicable state's secretary of state or equivalent business registration authority.
2. Primary state — State of principal place of business.
3. Specialization tags — Up to 5 subject-matter tags drawn from the NICE Cybersecurity Workforce Framework (NIST SP 800-181 Rev 1), which defines 52 work roles across 7 categories.
4. Certification markers — Notation of firm-level certifications (FedRAMP, CMMC, SOC 2 Type II attestation) or practitioner-level credentials (CISSP, CISA, CEH) held by named principals on public record.
5. Regulatory alignment — Flags indicating documented practice alignment with NIST CSF 2.0, HIPAA Security Rule (45 CFR Part 164), PCI DSS v4.0, or NYDFS 23 NYCRR 500.
6. Source basis — The named public document or database from which the entry data was drawn (e.g., SAM.gov contractor record, state corporation database, CISA partner listing).
7. Last confirmed date — The calendar quarter in which entry data was last cross-checked against its source.

A firm appearing without a certification marker is not uncertified — it means no certification was located in the indexed public sources at the time of the last confirmation check. Absence of a flag is an indexing boundary, not a quality judgment. For guidance on applying these fields to a specific research task, consult How to Use This Cybersecurity Resource.

What Listings Include and Exclude

Included:

• Commercial cybersecurity firms with a US principal place of business documented in a state business registry
• Solo practitioners holding at minimum one ANSI/ISO-accredited certification (CISSP issued by ISC2, CISA issued by ISACA, or equivalent) and operating under a registered business entity
• Managed Security Service Providers (MSSPs) with a publicly documented SOC 2 Type II report or equivalent third-party attestation
• Academic and nonprofit entities with CISA-designated status as a National Center of Academic Excellence in Cyber Defense (CAE-CD)

Excluded:

• Firms operating exclusively outside the United States, even if they hold US subsidiary registrations without documented US-based delivery operations
• Individuals offering cybersecurity services without a registered business entity, regardless of credential level
• Firms under active federal debarment as listed in SAM.gov's exclusions database
• Vendors whose primary product is hardware (firewalls, HSMs, endpoint devices) without a documented managed service or professional service line

The inclusion boundary is conservative by design. A firm meeting partial criteria appears in a "pending review" queue rather than in the primary index. This two-tier model — active listings versus pending — is consistent with the classification approach described in Cybersecurity Topic Context.

Verification Status

No entry in this directory carries a warranty of current accuracy. Cybersecurity firm status changes rapidly: certifications lapse, firms dissolve, mergers alter legal names, and CMMC assessments expire on a 3-year cycle per 32 CFR Part 170, the DoD rule codifying CMMC program requirements.

Verification operates on a rolling quarterly schedule. Entries flagged as "Q-verified" have had their source documents cross-checked within the preceding 90 days. Entries showing only an annual confirmation date may reflect data up to 12 months old.

Three primary authoritative databases anchor verification:

1. SAM.gov — For federal contractor registrations, cage codes, and active/inactive status
2. CISA partner and CAE registries — For academic and nonprofit designations
3. State secretary of state databases — For legal entity standing in the entity's primary state

Practitioner credential verification relies on the public verification portals maintained by ISC2 (for CISSP), ISACA (for CISA and CISM), and CompTIA (for Security+ and CySA+). Those portals allow credential number lookup against active certification records, providing a direct source check independent of self-reported data.
