Endpoint Security Listings

The listings indexed on this site represent endpoint security service providers, solution vendors, and consulting firms operating within the United States. Entries are organized to support procurement research, vendor qualification, and competitive benchmarking across the endpoint protection sector. The Directory Purpose and Scope explains the criteria governing which categories of providers qualify for inclusion and how coverage boundaries are defined.

Geographic distribution

Provider listings span all 50 states, with concentration patterns reflecting the geographic distribution of the US cybersecurity industry. The highest density of listed providers operates out of California, Virginia, Texas, Maryland, and New York — reflecting the proximity to major federal contracting hubs, technology corridors, and financial sector concentrations in those states.

Virginia and Maryland listings skew heavily toward providers holding federal authorizations, including FedRAMP-authorized endpoint detection and response platforms and firms engaged under Continuous Diagnostics and Mitigation (CDM) program task orders administered by the Cybersecurity and Infrastructure Security Agency (CISA). California listings are more heavily weighted toward commercial enterprise vendors and managed detection and response (MDR) providers serving technology-sector clients.

Providers operating nationally with no fixed regional headquarters are listed under a national scope designation. Listings do not exclude smaller regional or state-specific firms — a provider serving a single metropolitan market is listed with its geographic scope noted in the entry. Coverage across less-populated states is thinner by market reality, not by editorial exclusion policy.

How to read an entry

Each listing entry is structured to allow direct comparison across providers without requiring the reader to leave the directory. Entries follow a standardized field set:

1. Provider name — Legal business name or registered trade name under which the provider operates.
2. Service category — Classification drawn from the endpoint security taxonomy used across this site (e.g., endpoint detection and response, mobile device management, vulnerability assessment, managed endpoint security).
3. Geographic scope — Whether the provider operates nationally, regionally, or within a named state or metro area.
4. Compliance frameworks supported — Named standards and frameworks the provider's solutions or services are documented to address, such as NIST SP 800-53, CMMC Level 2 or Level 3, HIPAA Security Rule, or CIS Controls v8.
5. Federal authorization status — Whether the provider holds a FedRAMP authorization (Authorized, In Process, or Ready), as listed in the FedRAMP Marketplace maintained by GSA.
6. Certifications held — Staff or organizational certifications relevant to endpoint security practice, including CISSP, CEH, CompTIA Security+, or vendor-specific credentials.
7. Contact and profile link — Direct link to the full provider profile or external site.

Entries do not include subjective ratings, editorial endorsements, or ranked ordering. The How to Use This Endpoint Security Resource page describes how to filter and cross-reference entries for specific procurement or research purposes.

What listings include and exclude

Included:

• Providers offering endpoint detection and response (EDR), extended detection and response (XDR), endpoint protection platforms (EPP), mobile device management (MDM), and unified endpoint management (UEM) as primary or significant secondary service lines.
• Managed security service providers (MSSPs) whose endpoint security practice accounts for a documented portion of their service portfolio.
• Consulting and professional services firms specializing in endpoint hardening, CIS Benchmark implementation, or endpoint compliance gap assessments against named frameworks such as NIST Cybersecurity Framework 2.0 or CMMC.
• Independent security assessors (C3PAOs) accredited by the Cyber AB where endpoint security assessment is within scope.

Excluded:

• General IT service providers whose endpoint security offerings are incidental to broader IT support contracts and not independently described.
• Resellers and distributors who do not provide services, integration, or implementation support beyond product fulfillment.
• Providers operating exclusively outside the United States without a documented US service presence.
• Individual freelancers or sole practitioners not operating under a registered business entity.

The distinction between an EPP and an EDR listing matters for procurement decisions. EPP solutions focus on prevention through signature-based detection, application control, and policy enforcement — as defined under NIST SP 800-83. EDR platforms add behavioral telemetry, threat hunting capability, and incident response tooling. Entries are classified according to the provider's own documented service descriptions, cross-referenced against publicly available product documentation where ambiguity exists.

Verification status

Listings on this directory carry one of three verification designations that reflect the level of editorial review applied to the entry:

• Claimed and verified — The provider has confirmed its listing details directly, and at least one independently verifiable credential (FedRAMP Marketplace status, state business registration, or named certification body) has been cross-checked against a public registry.
• Claimed, unverified — The provider has submitted or claimed the listing, but independent credential verification has not been completed against a named public registry.
• Directory-indexed — The entry was populated from publicly available sources (federal procurement databases, CISA vendor advisories, GSA schedules) and has not been claimed or directly confirmed by the provider.

Verification does not constitute endorsement, security clearance, or certification. Regulatory compliance claims within listings — such as FedRAMP authorization level or CMMC C3PAO accreditation — are sourced from the FedRAMP Marketplace (marketplace.fedramp.gov) and the Cyber AB Marketplace (cyberab.org), both of which are publicly accessible registries. Listings citing CISA-recognized capabilities reference the CISA Known Exploited Vulnerabilities catalog and CDM program documentation as applicable.

The full listings index is accessible through the Endpoint Security Listings landing, which supports filtering by state, service category, and compliance framework.
