Room For Improvement

Auth0 needs improved flexibility, documentation, UI, and integration while addressing pricing, MFA, error handling, and deployment challenges.
Fortinet FortiAuthenticator struggles with integration, complex setup, limited customization, high pricing, and needs better support and documentation.
The only area for improvement is that Auth0 Platform cannot handle requests for developing APIs for legacy systems, such as mainframe models, where ForgeRock and IBM Security Verify Access can be utilized.
Senior Manager And Vice President at a tech vendor with 10,001+ employees
We must subscribe to a major plan to access most of their features. While this works well for larger companies, for small companies or those conducting POCs, this affects our budget allocation for other initiatives.
Lead Engineer at a tech vendor with 11-50 employees
By default, the user profile does not contain the name, first name, or address, which I would expect.
CTO at Lambda-X Ophthalmics
For example, authentication for wireless users expires after 24 hours, requiring re-authentication daily.
Head of computer systems at Indian Institute of Space Science & Technology(IIST)
For example, Cisco Duo is on the cloud, so we cannot compete with that part if a user requires a cloud-based two-factor authentication solution.
Presales Consultant
I recommend Fortinet make its images migratable between environments.
Senior Network and Security Engineer at Symbol Technologies PLC
 

Setup Cost

Auth0 Platform offers cost-effective pricing with mixed reviews on transparency, particularly for enterprises needing additional features and support.
Fortinet FortiAuthenticator is cost-effective, offers scalable licensing, and is favored over competitors for budget-conscious enterprises.
A downside I remember mentioning is that pricing can be high at scale, though that is not a product issue; it relates more to the nature of large enterprise solutions.
Partner Account manager at a wholesaler/distributor with 51-200 employees
Considering the amount of features I use, such as multi-factor authentication, it is affordable and comparatively less for the features it is giving compared to other existing platforms.
Associate Software Engineer at a computer software company with 201-500 employees
The cost of the solution itself was cost-effective enough that I didn't even need to compare it with EntraID.
CTO at Lambda-X Ophthalmics
Fortinet FortiAuthenticator is not overly expensive compared to other Fortinet subscriptions.
Senior Network and Security Engineer at Symbol Technologies PLC

Featured Reviews

Partner Account manager at a wholesaler/distributor with 51-200 employees
Identity workflows have transformed how we secure logins and manage user access daily
There are different elements to the best features Auth0 Platform offers, and I have touched on them, particularly the ability to help applications authenticate and authorize their users and manage their identities. A big point is identity federation, allowing connections across multiple identity providers, enabling users to log in using existing accounts due to databases and enterprise identity systems. A strong security feature is provided, particularly with their MFA, multi-factor authentication, which includes bot detection and brute-force protection, along with breached password detection, which is really good as an added extra. Auth0 Platform has positively impacted our organization, particularly in terms of usability. While we are not selling it directly, I find the platform easy to use for authenticating different users. Our own services team handles the implementation, so I cannot comment on the ease of that process. However, whenever we have had contracts and bids to roll out services, it has been really easy. We have seen improved security due to the implementation of Auth0 Platform. User management, such as creating and deleting users, is all about enhancing the user experience, which is massive. We assist with password resets and account linking. The time to implement is shorter, and we maintain a consistent user experience with a secure login flow, benefiting from a faster implementation due to the universal login, providing a hosted login page customizable by developers.

Supports secure remote authentication and provides comprehensive user activity tracking
The most important feature is the security capability because it provides a substantial amount of security for admin-related activities. Fortinet FortiAuthenticator can be used from anywhere in the world, and the authenticator services function globally. This global accessibility is one of the critical advantages, particularly since admin features are critical and security is a real concern. With Fortinet FortiAuthenticator, secure usage of firewall services and related functions is achieved. A complete log of all users who access the authenticator setup is maintained. Monthly logs are reviewed to check for any unnoticed activities. Each authenticated user's complete activity history is recorded. This logging capability allows for providing access to more admin users while ensuring security is not compromised and all users can be monitored.
