Cloud Security Directory: Purpose and Scope
The Cloud Security Authority directory catalogs professional service providers, consultancies, managed security service firms, and tooling vendors operating within the cloud security sector across the United States. This page defines the geographic boundaries of the directory, explains how the listing structure is organized, documents the qualification criteria applied to each entry, and describes the editorial process by which listings are added, updated, and removed.
Geographic coverage
The directory covers cloud security service providers operating within the United States at the national, regional, and state levels. Entries are classified by the geographic scope of the services they deliver — distinguishing between firms offering nationally distributed services, those concentrating on specific regions such as the Northeast or Pacific Coast, and those whose delivery model is entirely remote and jurisdiction-agnostic by nature of cloud-native service delivery.
Federal regulatory context shapes this coverage in concrete ways. Providers serving U.S. federal agencies must meet authorization requirements under the Federal Risk and Authorization Management Program (FedRAMP), administered by the General Services Administration. Firms handling protected health information are subject to the HIPAA Security Rule at 45 CFR Part 164, enforced by the HHS Office for Civil Rights. Organizations processing payment card data operate under PCI DSS v4.0 requirements issued by the PCI Security Standards Council. Each of these regulatory regimes influences which service competencies are material to an entry's classification within the directory.
International providers are included only when they maintain a documented U.S.-based service delivery operation, hold relevant U.S. compliance certifications, and can demonstrate direct engagement with American regulatory environments. Providers operating exclusively under EU frameworks such as GDPR (EUR-Lex, Regulation 2016/679) without a U.S. service footprint fall outside the current scope of this directory.
How to use this resource
The directory is structured to serve three distinct user types: procurement professionals conducting vendor evaluations, security researchers mapping the service landscape, and industry analysts assessing market segments. Each entry in the Cloud Security Listings presents standardized information fields — service category, delivery model, applicable compliance frameworks, and verified credentials — enabling direct comparison across providers without navigating individual vendor marketing materials.
Listings are organized by primary service category. The five active categories are:
- Managed Cloud Security Services (MCSS) — continuous monitoring, threat detection, and incident response delivered as an ongoing managed service
- Cloud Security Architecture and Consulting — project-based advisory covering control design, shared responsibility model alignment, and zero-trust architecture
- Cloud Compliance and Audit Services — assessment and attestation work tied to named frameworks including NIST SP 800-53 Rev. 5, FedRAMP, and CMMC 2.0
- Cloud Identity and Access Management (IAM) Specialists — focused providers whose primary service line is identity governance, privileged access management, and federation in cloud environments
- Cloud Security Tooling and Platform Vendors — commercial software and SaaS products providing cloud-native security capabilities such as CSPM, CWPP, or CASB functions
Filtering by compliance framework is available through the How to Use This Cloud Security Resource guidance page, which documents the exact filter logic and category definitions in detail.
Standards for inclusion
Inclusion in this directory requires that a listed entity meet a defined threshold across four criteria. Partial satisfaction of these criteria results in a provisional listing designation until outstanding documentation is received and verified.
Criterion 1 — Service Legitimacy. The entity must operate as a legally registered business within a U.S. jurisdiction, with a verifiable business registration or tax identification number. Sole proprietors offering cloud security services qualify under the same criteria as incorporated entities.
Criterion 2 — Demonstrated Domain Competency. At least one of the following credential categories must be documented: (a) staff holding certifications recognized by ISACA (CISM, CRISC), (ISC)² (CCSP, CISSP), or the Cloud Security Alliance CCSK/CCZT programs; (b) the organization itself holds a current FedRAMP authorization or a SOC 2 Type II attestation issued within the prior 24 months; or (c) the entity is a registered CSA STAR participant at Level 1 or above via the CSA Cloud Controls Matrix registry.
Criterion 3 — Active Service Delivery. The provider must demonstrate active client engagement within the cloud security domain. Entities that have ceased active service delivery, are in administrative dissolution, or operate solely as referral intermediaries without direct service delivery capability are excluded.
Criterion 4 — No Disqualifying Regulatory Action. Entities subject to unresolved enforcement actions from the FTC, HHS Office for Civil Rights, or equivalent state-level regulators that are directly related to information security failures are ineligible until the enforcement action is formally resolved.
Managed security service providers and consulting firms are evaluated under the same framework — the distinction between service types affects category assignment, not inclusion eligibility.
How the directory is maintained
Directory records are reviewed on a 12-month cycle. Each review cycle initiates an outreach process to listed entities requesting confirmation of active status, updated credential documentation, and correction of any changed service scope or contact information. Entries that do not respond within 60 days of the initial outreach contact are flagged as unverified and marked accordingly in the listing display.
New listing requests are processed through the submission form accessible from the contact page. Submitted entries undergo the four-criterion evaluation described above before publication. The review period from submission to publication decision is typically 30 business days, contingent on documentation completeness at submission.
Removal from the directory follows one of three trigger conditions: voluntary withdrawal by the listed entity; confirmed business closure identified through public business registration records; or discovery of a disqualifying regulatory action as defined under Criterion 4. Removals are logged and the reason category (voluntary, closure, or disqualification) is retained in an internal record, though the specific grounds for disqualification-based removals are not published publicly.
The directory does not accept paid placement or sponsored positioning. Listing order within each category is determined by alphabetical sort on entity name, ensuring no commercial relationship influences display prominence. This editorial independence policy aligns with the reference authority standards maintained across the parent network, of which nationalcyberauthority.com serves as the foundational cybersecurity reference domain.
