Frontegg is a comprehensive Customer Identity and Access Management (CIAM) platform built for the unique needs of SaaS companies. It eliminates the complexity of authentication, authorization, and user access by giving engineering teams a fast and reliable way to deploy advanced identity features, while also enabling non-technical teams to manage identity without constant developer involvement.
For developers, Frontegg provides a low-code integration experience that gets identity up and running in days rather than months. Its SDKs and APIs support popular frameworks and languages, including React, Node.js, and Python, making it easy to embed features like single sign-on (SSO), multi-factor authentication (MFA), passwordless login, and role-based access control (RBAC). Developers can also handle complex SaaS requirements such as multi-tenancy, hierarchical user structures, entitlements, and subscription management with ready-to-use capabilities, avoiding the need to build these features from scratch.
Once integrated, Frontegg gives non-technical stakeholders control through a secure, intuitive admin portal. Product teams can manage feature entitlements and experiment with configurations. Infosec teams can enforce compliance policies, manage MFA requirements, and monitor security dashboards. Customer Success can fulfill requests like adding users or connecting an SSO provider instantly, without waiting on engineering. This distribution of ownership reduces bottlenecks and accelerates how fast companies can respond to their customers.
Security is at the core of Frontegg. The platform stays aligned with the latest identity standards such as OAuth2, SAML, and OpenID Connect. It provides built-in audit logs, real-time monitoring, and policy enforcement to help organizations meet compliance requirements. By removing the burden of ongoing identity maintenance from developers, Frontegg ensures applications remain secure without slowing down innovation.
