Whether you’re building a startup app or managing enterprise-scale infrastructure, FusionAuth delivers all the must-have features — from login and SSO to advanced protocols like OAuth2, OIDC, SAML, and WebAuthn — in a self-hostable or cloud-native package.
Designed with developers in mind, FusionAuth integrates seamlessly with any language, framework, or architecture. Every capability is API-first and built for extensibility, so you can tailor authentication workflows without getting locked into rigid, inflexible systems.
FusionAuth supports all the key use cases — user registration, multi-factor authentication (MFA), passwordless login, role-based access control, and more — while helping you stay compliant with GDPR, HIPAA, PCI, and other regulatory standards.

Auth0 takes a modern approach to Identity, providing secure access to any application, for any user. Safeguarding billions of login transactions each month, Auth0 delivers convenience, privacy, and security so customers can focus on innovation. Auth0 is part of Okta, The World’s Identity Company™.
Auth0 lets you quickly integrate authentication and authorization for web, mobile, and legacy applications, with new Fine Grained Authorization (FGA) that goes beyond role-based access control.
Authenticate users across all applications with a customized, secure, and standards-based single login. Universal Login connects users to a central authorization server. Credentials aren’t transferred across sources, which boosts security and protects against phishing and credential stuffing attacks. OAuth 2.0 recommends that only external user agents (like the browser) be used by native applications for authentication flows. Auth0’s Universal Login achieves this while enabling SSO.

BlastShield
BlastShield is a zero-trust, software-defined perimeter solution designed to protect critical IT and OT assets by rendering them invisible and inaccessible to unauthorized users. It establishes an encrypted, peer-to-peer overlay network that cloaks protected devices and data from network scanning or traffic analysis tools, preventing credential theft, reconnaissance, and lateral movement. BlastShield combines phishing-resistant, passwordless multi-factor authentication (including mobile authenticators or FIDO2 keys), microsegmentation, data-in-motion encryption, and policy-based access controls to ensure only explicitly authorized devices and users can connect. It supports deployment across a wide range of network environments, TCP/IP, SCADA, SD-WAN, or even raw Ethernet, and can protect everything from legacy OT/ICS equipment, sensors, PLCs, HMIs, cloud VMs, and virtual infrastructure.
