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.

Multi-factor security has improved device protection but still needs broader application coverage
Fortinet FortiAuthenticator could be improved in its cost structure. Although it is not expensive, other solutions offer more value for less money. Cisco Duo provides better value in this regard and connects to web applications much more easily, scaling effectively in that sense. While I have never used Cisco Duo to secure other devices in IoT environments, I know Cisco Duo is capable of doing so, whereas Fortinet FortiAuthenticator cannot. Additionally, Cisco Duo is also cheaper. These are the main reasons why we switched away from Fortinet FortiAuthenticator, as it was very limited compared to other solutions available. Fortinet FortiAuthenticator was primarily missing the ability to scale to web applications.

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 the communication based on PKI certificates."
"The public key infrastructure certificates issued by the PKI servers helped me set up good client-server authentic communications."
"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."
"We use multi-factor authentication for enhancing security."
"The product's on-premise version doesn't have recurring costs."
"The most important feature is the security capability because it provides a substantial amount of security for admin-related activities."
"Features the addition and removal of access as needed for the VPN."
"We switched to FortiAuthenticator because it integrates with our Fortinet products."
"The solution is easy to learn and makes it easy for our users to add FortiToken, and it's very easy to integrate if you have other Fortinet devices."
"It is used for SSO, single sign-on, and as a captive portal."
"This is a very important product if a company wants to use a VPN."
 

Cons

"From an automation perspective, PKI is a bit of a debatable topic and can be improved as time demands."

"A lot of configurations are available only from CLI."
"The customization capability of Fortinet FortiAuthenticator is not very flexible."
"Fortinet FortiAuthenticator's initial setup process could be easier."
"Lacks a simplified two-factor authentication process."
"I would like to see more integration and inclusion of features for ransomware protection directly within the FortiAuthenticator without requiring additional devices."
"One of our clients has faced a lot of issues with FortiAuthenticator. For example, one of the devices restarted by itself, and the database was corrupted."
"I would like to see more security features in reference to identity login or identity identification."
"Improvements in the product could start from the dashboard, overall customization, and configuration."
 

Pricing and Cost Advice

"This solution won't cost much, as this would be free with the licensing from Microsoft."
"I would rate it seven for the price."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"It costs more to license the high-availability option."
"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 platform provides a user-based pricing model rather than a subscription pricing model."
"The pricing is fair."
"The product could be more competitively priced."
"The platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"We pay for licensing on a yearly basis."
