Indra Maulana - PeerSpot reviewer
Business Solution and Development Manager at PT ADPS
Tailored to the lifecycle management needs of banks
The customer finds value in adopting a platform from Jira, particularly for the ease it brings to their processes, both for on-premises operations and batch processing. Their objective is to create a new customized server specifically designed for generating certificates. This server is intended for the generation of certificates, emphasizing that it is not meant for free domain replacement. The platform of choice for this purpose is Digital One, a product that offers full customization and aligns well with the customer's preference for tailored solutions. The process of certificate issuance from Microsoft's AB involves renewal or replacement every five years. However, an issue arises in that this particular certificate requires renewal annually instead of the standard five-year cycle. The challenge is attributed to personnel changes, where an administrator responsible for the process resigns within the five-year period. To address this, we seek an automated solution that operates seamlessly with a single sign-on approach, eliminating the need for user IDs or passwords. The automation involves approval and subsequent deployment without complexities. Being a partner of DigiSet, we rely on the implementer for support in service deployment, installation, and resolution of any issues that may arise.

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.

Quotes from Members

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

Pros

"I emphasize the importance of automation in Wi-Fi management, particularly in tasks such as certificate renewal. The requirement extends to the ability to generate new certificates from a local server within the data center. There is a need to establish a new server for local certificate issuance and highlights the desire for automation in the deployment process. The emphasis lies in leveraging automated solutions to streamline these operations effectively."
"The public key infrastructure certificates issued by the PKI servers helped me set up good client-server authentic communications."
"The most valuable feature is the communication based on PKI certificates."
"The most valuable feature of the solution is RADIUS service and the social network integration feature."
"The most valuable feature is the OTP on the mobile phone."
"The ease of use is really nice. Using Authenticator, I've been able to actually work better on my authentication due to the fact that I have a single fabric to authenticate control from my firewall and on my access points. Authentication takes place from this area."
"It integrates very tightly with the rest of the Fortinet ecosystem."
"Enables easy integration, allowing for 2FA with our VPN."
"I prefer the passing tool that sent an active directory console to a Fortinet FortiAuthenticator, then Fortinet FortiAuthenticator does not pass the locks."
"The most valuable feature is the flexibility in using the SMS messages."
"FortiAuthenticator is really good software that integrates very well with Fortinet products."

"From an automation perspective, PKI is a bit of a debatable topic and can be improved as time demands."
"Up to now, I would not recommend FortiAuthenticator to others yet as I have ongoing transitions and evaluations."
"It does the job I paid for, but the graphical interface could be improved."
"A lot of configurations are available only from CLI."
"Lacks a simplified two-factor authentication process."
"Initially, we deployed Fortinet FortiAuthenticator on VMware and faced challenges when migrating to an OpenStack environment, which required reconfiguration. I recommend Fortinet make its images migratable between environments."
"FortiAuthenticator should integrate with other applications."
"The GUI is on the older side but I'm sure that it will be upgraded soon. It works, but it looks a little dated."
"I don't have any issues with this solution, but it may need a better, more user-friendly interface or better design of the platform."
 

Pricing and Cost Advice

"I would rate it seven for the price."
"This solution won't cost much, as this would be free with the licensing from Microsoft."
"I would rate the pricing a four out of ten, where one is cheap, and ten is expensive. It is not that costly. It is cheap, easy to manage, easy to install, and easy to configure."
"The cost of the license could be less expensive. The license is paid on a yearly basis."
"You can pay as you go with them. You purchase a base license and add to it as needed."
"I would start off with a VM including the base license and scale according to the number of users you need to authenticate."
"The platform provides a user-based pricing model rather than a subscription pricing model."
"I rate its pricing a three to five out of ten."
"On a scale of one to ten, where one is a high price and ten is a low price, I rate the pricing a seven."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
