Featured Reviews

Serge Wautier - PeerSpot reviewer
Simplified integration with helpful support and decent pricing
Auth0 is used as an identity provider for our new SaaS platform to manage the identity of users Auth0 is cost-effective because it provides all the features we need, and it was very easy to integrate into our platform. The documentation is comprehensive, and their support team is highly helpful.…
Ben Ruset - PeerSpot reviewer
Streamlines access management with top-notch support, and a user-friendly interface, making it a highly effective solution for businesses of all sizes
During my evaluation of various products, one standout feature of OneLogin that impressed me was their mobile app for authentication through push notifications. Unlike traditional methods involving rotating codes, the OneLogin app simplifies the process by sending a push notification asking if the login attempt is legitimate. If confirmed, the login proceeds seamlessly. The primary benefit is its user-friendly interface, making it particularly accessible for non-technical users. One aspect I particularly appreciate is their exceptional customer support whenever I've needed assistance. Their sales team has also been highly responsive and helpful in connecting me with necessary resources, although we haven't faced any major challenges.
Muzi Lubisi - PeerSpot reviewer
Improved user experience with seamless integration and easy installation
The feature that I mostly valued is the ease of installation on different systems, especially on Windows. Additionally, it is very beneficial for deploying single sign-on sessions between different windows on a web browser, provided I am connected to the right identity provider. That seamless integration significantly improves user experience and efficiency.

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 of the product is scalability."
"The most valuable feature is interface application integration, but we haven't fully used it yet. We'll need it in the future for a few potential clients."
"The most important feature for me was the ease of use, as it needed to be easy to integrate into my platform."
"If we had to develop our own and manage it, it would take years of development and maintenance. In those terms, it’s definitely beneficial."
"The most valuable feature is that it is simple to integrate, irrespective of your codebase."
"It has a lot of customization and out-of-the-box features."
"The most important feature for me was the ease of use, as it needed to be easy to integrate into my platform."
"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's super useful to have a single pane of glass when it comes to access management."
"The solution allows the user to search logs based on a specific time."
"Documentation."
"OneLogin is efficient."
"Simplicity is the most valuable part of OneLogin."
"The single sign-on and the fact that we can integrate everything in one place and control from there were valuable features of this solution."
"One aspect I particularly appreciate is their exceptional customer support whenever I've needed assistance."
"The solution's ability to save and manage of all my passwords is great."
"Symantec Siteminder Is both scalable and stable."
"If you look at our organization, and really all financial institutions, we have a lot of legacy apps. So it really helps to get Single Sign-On."
"It has the ability to authenticate and authorize users. It is the main feature for our security."
"The authentication and single sign-on features of Symantec Siteminder are valuable."
"The solution has features that allow you to easily distinguish between protected and unprotected resources."
"That seamless integration significantly improves user experience and efficiency."
"Ease of use is very good, for administrating it. It's very well known."
"I liked the debugging part. There are only two files (trace file and log file) that you need to look into while performing debugging, and the logs give you the exact info on where and what needs to be fixed."
 

Cons

"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."
"There are indeed areas where the product could improve. For instance, Okta offers various application configurations, enabling access management, which the tool could consider implementing."
"The pricing should be lower. A reduction of 20-25% would be great."
"If you’re not a developer, you need to spend time exploring more."
"The price modelling is a bit confusing on the site and can be costly."
"The tool's price should be improved."
"This is a costly solution and the price of it should be reduced."
"The product could use a more flexible administration structure"
"OneLogin offers a Virtual LDAP feature that we utilize, although it differs slightly from traditional LDAP servers."
"To offboard, you have to manually click on this checklist, each of the checkmarks. It would actually be really nice if, for offboarding someone, you just click "offboard" and it automatically runs a script to do that."
"We've been experiencing some pain points since the acquisition. For example, there have been some outages we didn't see previously, which are a big topic with my executive team. You have hundreds of applications relying on this service for login. If the service is unavailable, nobody can log into these applications."
"The uptime has not been great recently, with some outages lasting six, seven, or eight hours."
"More off-hour support."
"In terms of managing the users on a large scale, it would be easier if they had some kind of user management portal."
"OneLogin needs to increase the number of connectors available out of the box to connect to the different endpoints. The number of out-of-box connectors should be increased."
"While I initially used OneLogin's desktop feature to extend SSO, I discontinued it two years ago due to limitations."
"The technical support could be better."
"CA has reporting at the moment. With the reporting, every particular segmented product has a reporting engine. I would like to see centralized reporting for all of them together."
"Siteminder needs to improve its user experience."
"All the problems that we reported actually have never been resolved. We could not capture enough information for CA to be able to debug the problem."
"We are finding some compatibility issues. We're still working with CA on them."
"I'd like to see a rework of the user directory configuration."
"Symantec SiteMinder is not easy to set up and maintain at an infrastructure level."
"Symantec Siteminder needs to have adaptive authentication and multi-factor authentication as integrated features."
 

Pricing and Cost Advice

"It is a relatively inexpensive product in the industry."
"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."
"There are different price levels: B2B, B2C, and enterprise. The basic plan is about $1,500 per month."
"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."
"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."
"We were happy with the price we got when we signed up, but I don't know what will happen when the time comes to renew because it is a different company now. We haven't seen any pricing models or had that discussion yet. My renewal is a year and a half away. It's worth what we're paying for it. There's no way we could provide the level of service for cheaper or try to do the same in-house."
"The pricing and licensing are reasonable. It is much cheaper than other products."
"While I wish OneLogin's pricing was more affordable, their licensing model, which is based on per user, is acceptable."
"Surprisingly expensive given the price of on-premise solutions."
"The price of the licensing is fine."
"OneLogin's pricing, from the perspective of the education sector, seems quite reasonable for the value it delivers."
"The pricing for OneLogin seems to be okay. The pricing and licensing are affordable. If you'd consider OneLogin to be expensive, it's worth it."
"It was cheap in the beginning, and then it became very expensive. We were initially charged $2 per user per month, which was fine, but by the second year, they increased it to $5 per user. That became very expensive for us because we had about 1,500 users. At $2 per user, it comes out to be $3,000 a month, which is $36,000 a year. If we move to $5 per user, it comes out to be $7,500 a month. That made its cost so high. That is why we removed the product because the cost was high."
"CA solutions are generally expensive but for the customer the ROI is big."
"Symantec Siteminder is expensive; they could definitely do better on the price."
"Siteminder is a little costly. You pay for licensing, and they offer packages, so if you have less users, then you have to buy different products at different prices. If you have more of a user base, then the package is different. They also include other features—for example, if you have a database and you're using Siteminder, then it's good to use a Semantic-specific database, but if you are using less, then you have to purchase the database separately. Whereas if you are going for a bigger license, then it comes within the package. It depends on which plan you are using."
"The licensing is fair for this solution."
"I recommend conducting a PoC on every available product before choose one."
"The price is quite comparable to the other enterprise-level solutions in that market."
"The solution's pricing is competitive."
"The pricing is reasonable."
