Sebastian Micu - PeerSpot reviewer
Auth0 | Ciam Consultant at Intragen
Platform has strengthened user security, improved sign-on journeys, and supported future growth
Regarding areas for improvement, Auth0 Platform is a premium product, and its pricing reflects its enterprise-grade capabilities. While the cost can sometimes make smaller businesses hesitate, the return on investment usually outweighs the initial price tag when the platform is architected and implemented correctly. The comprehensive feature set, top-tier security, and reduced development time justify the investment for organizations prioritizing scalability. On the technical side, I would like to see Auth0 introduce more no-code branding options for Universal Login. Currently, achieving a highly specific, bespoke login experience often requires utilizing Liquid page templates or the newly released Advanced Customizations for Universal Login. While these are incredibly powerful tools, they do require some technical expertise to execute flawlessly. Having more robust, out-of-the-box customization options would be a great enhancement in the future.

Facilitates improvement through feedback collection, quizzes, and event data generation
Gluu has a mobile app catering to field workers. Normal workers use the web app, a complete cloud-based solution. They log in on any device and access the system. Gluu filters and displays relevant information based on the user's role in the processes. Users can set it up to view as a viewer, worker, manager, or controller of the area. The front end offers different views but provides an easy dashboard for employees. On the dashboard, users can configure it to show tasks, related work instructions, and connected processes. It's very user-friendly, allowing end-users to understand their tasks and processes without needing in-depth knowledge.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable feature is that it is simple to integrate, irrespective of your codebase."
"What attracted me to Auth0 Platform is how simple and easy it is to implement with my applications."
"The most important feature for me was the ease of use, as it needed to be easy to integrate into my platform."
"There have been many improvements in our cloud technology since we are using Auth0 Platform, and it reduces our development time while providing many features to integrate and utilize so that everything is available in one place and we can develop our application faster, which minimizes our time and maximizes utilization."
"It is easily connected and easy to put our app in single sign-on."
"I feel it has been a very prudent investment, as I get everything I want and more from it for what I invest, and currently I feel that Auth0 Platform is very affordable."
"It's a very powerful platform. It has the ability to do the usual stuff, according to modern protocols, like OIDC and OAuth 2. But the real benefit of using the platform comes from its flexibility to enhance it with rules and, now, with what they call authentication pipelines. That is the most significant feature, as it allows you to customize everything regarding the authentication and authorization process."
"It has improved our organization by providing login authentication for a mobile app."
"Most of the features are related to banking within this particular IT industry. Security and the market are also important features."
"Gluu has a mobile app catering to field workers. Normal workers use the web app, a complete cloud-based solution. They log in on any device and access the system."
 

Cons

"There is a possibility to improve the machine-to-machine authentication flow. This part of Auth0 is not really well documented, and we could really gain some additional knowledge on that."
"I find it surprising that there is no access to a standard user profile."
"I think they can do a better job in explaining what you're supposed to do next in order to correctly follow an idiomatic approach to using the solution beyond simply passing a JWT token to a server and having the server check then signature to validate the token."
"The product could use a more flexible administration structure"
"Auth0 Platform is not as flexible compared to ForgeRock or IBM Security Access Manager."
"There could be easy integration with IoT devices for the product."
"In my previous experience a couple of months ago, I checked and the permissions assigned to the user were not working, but then I had to update it by going to its company and then providing the particular permissions."
"The tool's price should be improved."
"The tool integrates AI into the process modeling aspect. I believe this addition will significantly enhance usability. Additionally, it might be beneficial to have the capability to import content from other tools into this platform. Our platform follows its business process modeling notation standard, which differs from BPM. It uses a simpler notation, making it easier. The ability to import content from other tools could accommodate users accustomed to different standards."
"I would like to see features around federation, authentication, authorization, and AI APIs with a ChatGPT interface."
 

Pricing and Cost Advice

"It is a relatively inexpensive product in the industry."
"The tool is cheaper compared to competing solutions. Those alternatives tended to be more expensive. Consequently, Okta purchased it because it was considerably cheaper. The solution even offered some free services while still providing excellent functionality."
"There are different price levels: B2B, B2C, and enterprise. The basic plan is about $1,500 per month."
"Pricing of Auth0 is a pain point. Their pricing model is very confusing, at least for an enterprise. I don't like their pricing model. I think it's too aggressive. It's not very cheap for a service that only does authentication."
"I am pretty happy with the pricing model of Auth0. It is very clear for me. Considering our scale, the features that we are using, and additional features that we bought, we still find it great. If you split the costs for the whole year and calculate the number of people you needed to hire, it always comes out to be much lesser than what we would have spent on building our own solution."
"The tool is cheaper compared to typical German products. I rate the product’s pricing a four out of ten."
"The price is reasonable."
