1Kosmos, a leader in identity proofing and passwordless authentication, announced on September 4, 2025, its designation as a Full-Service Credential Service Provider (CSP) under the General Services Administration’s (GSA) newly established Special Item Number (SIN 541519CSP). Partnering with Carahsoft Technology Corp., this milestone validates 1Kosmos as a trusted vendor for secure, NIST-aligned digital identity services, enabling federal agencies to modernize identity infrastructure efficiently.
Designation: 1Kosmos named Full-Service CSP under GSA SIN 541519CSP, announced September 4, 2025.
Partnership: Secured with Carahsoft Technology Corp., expanding access via multiple procurement vehicles.
Capabilities: End-to-end enrollment, identity verification, authentication, and credential lifecycle management.
Compliance: Meets NIST SP 800-63, Kantara Trust Status, and FedRAMP High Authorization standards.
Market Impact: Addresses sixfold growth in federal credential spending, from $6M to $36M in recent years.
Leadership Quote: “This designation reinforces 1Kosmos as a proven, high-assurance credential service provider,” said CEO Hemen Vimadalal.
The GSA introduced SIN 541519CSP in May 2024 to streamline procurement of digital credentialing services, identifying pre-vetted vendors compliant with NIST SP 800-63 Digital Identity Guidelines. Qualifying vendors must be listed on the Kantara Trust Status List, demonstrate adherence to NIST’s Identity and Authenticator (I&A) requirements, and hold at least a FedRAMP Moderate Authorization to Operate (ATO). 1Kosmos exceeds these with its FedRAMP High-authorized cloud platform, ensuring secure identity proofing and lifecycle management at scale.
1Kosmos delivers:
End-to-End Identity Solutions: Enrollment, identity verification, authentication, and credential lifecycle management.
Privacy-by-Design: A reusable identity wallet protects user PII, complying with GDPR, CCPA, and BIPA.
Phishing-Resistant Authentication: Certified to NIST 800-63-3, FIDO2, and ISO/IEC 30107-1/3 for liveness detection.
Scalability: Performs millions of daily authentications for government and private sector clients globally.
Hemen Vimadalal, CEO of 1Kosmos, stated, “As agencies modernize their identity infrastructure, 1Kosmos offers faster procurement, lower integration risk, and a FedRAMP High-authorized cloud platform built for secure identity proofing and lifecycle management at scale.” Tyler Nelson, Sales Manager at Carahsoft, added, “This accomplishment highlights 1Kosmos’s dedication to providing advanced cybersecurity solutions for government agencies.”
The GSA reports federal spending on credential services surged from $6 million to $36 million in recent years, with the Department of Veterans Affairs alone accounting for $18.83 million in FY2023 awards. This reflects growing demand for secure digital identity solutions amid rising identity fraud. 1Kosmos’ inclusion in SIN 541519CSP, following its FedRAMP High Authorization in June 2025 and a $194.5 million Login.gov BPA with Carahsoft in October 2024, positions it as a leader in federal digital identity services.
Available through Carahsoft’s procurement vehicles (GSA Schedule No. 47QSWA18D008F, SEWP V, ITES-SW2, NASPO ValuePoint, OMNIA Partners, E&I Contract), 1Kosmos’ solutions enhance accessibility for federal, state, and local agencies.
Headquartered in Iselin, New Jersey, 1Kosmos unifies identity proofing and passwordless multi-factor authentication, preventing identity impersonation and fraud while ensuring user privacy. Backed by Forgepoint Capital and Gula Tech Adventures, it serves major banks, telecoms, healthcare, and government agencies, conducting millions of daily authentications.
