We engineer cloud-native IAM solutions with passwordless authentication, FIDO2 security,
and cryptographic signatures for regulated environments. NIST SP 800-63 compliant
architectures using cutting-edge technology and modern security practices.
We provide expert consultancy and advisory services to help organizations design, implement, and maintain NIST-compliant Identity and Access Management systems. Specialized expertise in modern authentication strategies including passwordless authentication, FIDO2 security keys, and architecting cloud-native IAM solutions for regulated environments.
We engineer Identity and Access Management solutions that protect digital identities through strong identity proofing, authentication, granular authorization controls, cryptographic implementations, and cloud-native architectures on AWS. Full compliance with NIST SP 800-63 standards using modern security practices.
Proximasus has 4+ years of specialized experience implementing NIST-compliant IAM systems for security-critical and regulated environments, with deployed solutions handling 100K+ daily authentications.
We deliver specialized technical capabilities in NIST-compliant Identity and Access Management systems with proven commercial expertise across all assurance levels.
Enterprise Identity and Access Management systems designed and implemented in accordance with NIST SP 800-63 guidelines, including identity proofing, authentication, lifecycle management, federation and risk-based access controls conforming to IAL, AAL, and FAL requirements.
Implementation of federation protocols including OpenID Connect, OAuth 2.0, and SAML to achieve specific Federation Assurance Levels (FAL) and Authentication Assurance Levels (AAL). Expertise in multi-factor authentication, token management, and assertion protocols for regulated environments.
Identity proofing solutions designed to meet Identity Assurance Level (IAL) requirements from IAL1 through IAL3. Implementation of identity verification, evidence validation, and biometric matching processes in accordance with NIST guidelines for Digital Identity.
Implementation of modern phishing-resistant authentication using FIDO2 security keys, passkeys (WebAuthn), and platform authenticators (Touch ID, Face ID, Windows Hello). We deploy passwordless solutions that achieve AAL3 compliance while improving user experience through biometric authentication and hardware security keys.
Advanced cryptographic implementations including digital signatures, Advanced Electronic Signatures (AdES), and Qualified Electronic Signatures (QES) conforming to eIDAS regulations. Expertise in PKI infrastructure, certificate lifecycle management, cryptographic key management, and signature validation for legally binding electronic documents.
Cloud-native security architectures on AWS including IAM policy design, Cognito user pools, API Gateway protection, and Secrets Manager integration. We implement OAuth 2.0 for APIs, JWT validation, rate limiting, WAF rules, and serverless authentication patterns for scalable, secure cloud applications.
Full-stack development of web applications, mobile applications, desktop applications, backend services, and APIs with integrated authentication and authorization. We implement OAuth 2.0, OpenID Connect, secure session management, and token-based access controls using modern frameworks, CI/CD pipelines, Infrastructure as Code, and AI-assisted development tools for rapid, secure delivery.
Native application development for Android, iOS, and desktop platforms with secure authentication integration. We implement applications that support OAuth/OIDC flows, passwordless authentication with passkeys and FIDO2, native biometric integration (Touch ID, Face ID, Windows Hello), secure token storage, and offline-capable architectures.
Risk-based authentication strategies, assurance level determination, and compliance mapping for NIST guidelines and industry regulations. Experience implementing Identity and Access Management solutions for healthcare, financial services, and government sectors requiring high assurance levels.
Proximasus has helped with delivering NIST-compliant IAM solutions for healthcare organizations in the United Kingdom. Our implementations handle sensitive patient data while conforming to IAL2+ and AAL2+ assurance requirements and strict regulatory compliance frameworks. Including AWS cloud deployments and qualified electronic signatures for patient consent workflows.
We help deploy software solutions in mission-critical environments where compliance to NIST standards is essential. Our deployed solutions handle 100K+ daily authentications, implementing passwordless authentication with FIDO2 security keys and passkeys, risk-based authentication strategies, multi-factor authentication at various AAL levels, and federation protocols meeting FAL requirements for cross-organizational access.
We architect identity proofing workflows conforming to IAL standards, implement authentication infrastructure meeting specific AAL requirements, and design federation systems achieving required FAL levels. Our work spans the full spectrum from FIDO2 authenticators and cryptographic signing to cloud-native API security on AWS, in sectors where NIST conformance is both a business requirement and a regulatory necessity.
We follow a structured five-phase approach to deliver secure software solutions that meet NIST compliance requirements while addressing your specific operational needs.
We analyze your current systems, security requirements, and regulatory obligations. We conduct risk assessments to determine appropriate assurance levels.
We help design software architecture for you that is conforming to required NIST levels.
We implement solutions using modern development tools including AI-assisted coding, automated testing frameworks, and cloud-native infrastructure. Our tech stack includes AWS services, modern CI/CD pipelines, Infrastructure as Code, and security-first development practices with real-time vulnerability scanning and automated compliance checks.
We help you deploy your software solution to your environments, configure integrations with your applications, and conduct security testing.
We provide ongoing maintenance, security updates, and technical support. We monitor system performance, continuously improve your software solution, and ensure it remains compliant with industry best standards.
