Alex Trauzzi, a developer and software architect, is using FusionAuth's Enterprise plan to meet the authentication needs of dealcloser, a transaction management hub for legal professionals. The company was originally using Auth0 but needed a solution that better fit their enterprise needs and could handle unique situations such as users needing to connect without internet access. An "air gapped" server, with no network interfaces connected to outside networks, presented a challenge for SaaS auth solutions like Auth0. However, FusionAuth's capabilities allowed dealcloser to seamlessly migrate their user database and quickly enable additional authentication features like SAML and Single Sign-on in seconds, rather than months of coding. The company is now able to leverage existing standards such as OpenID Connect without significant development effort.
