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

"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 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."
"This is a cost effective and flexible solution."
"The feature I value the most is the one-time passwords because it helps to authenticate users so you know the timing of their usage."
"The most valuable feature I find in FortiAuthenticator is web filtering."
"The initial setup is so easy and there is no problem in the implementation."
"Features the addition and removal of access as needed for the VPN."
"Fulfilled our requirement at a good price."
"In terms of benefits, the tool provides both cost savings and efficiency, but efficiency is more important for our customers."
"The biggest advantages of Fortinet FortiAuthenticator are that it's easy to deploy, easy to manage, and the GUI is a very strong interface."
