Featured Reviews

VC
Senior Software Engineer at Charter Communications
Secure API access for enterprises has improved and provides dynamic authentication for users
The best features Auth0 offers are its scalability and it is a better way of authenticating a user compared to just a tokenized version of authentication where the token is static and does not offer dynamic authentication compared to how Auth0 offers it. While working in a dynamic environment where there are many enterprises involved in the service, you need a tool that can authenticate them on the go, which is why I like it. Auth0 has positively impacted my organization. Previously we used the tokenized version of authentication. The work was simple, but when you push this code to deployment and enterprises are involved, it makes much more sense to authenticate them through Auth0 so that you can just get a login for yourself when you are authenticated, which helps to dynamically scale depending on the product and its viability. The specific outcomes since I started using Auth0 include time-saving, more security, and scalability, which are the three things I would emphasize.

Integration capabilities simplify authentication and migration challenges need addressing
The integration capabilities of Fortinet FortiAuthenticator are very interesting, as it can be integrated with third-party devices easily and is straightforward to configure. The integration with FortiToken is outstanding, adding a layer of security for authentication. In addition, it can be used by integrating with zero trust single access, enhancing overall security measures.
