Senior Network Security Consultant at a tech vendor with 10,001+ employees
Manages network threats and supports application control with ease
The best advantage of F5 Silverline Managed Services is that it is easy to use. The admin guide they provide is easy to understand and allows for implementation within a few days. The traffic manager and the monitoring tool are valuable as well. The monitoring tab displays GET and POST requests in a readable format, making it accessible even to non-tech-savvy individuals. It offers effective reports and monitoring capabilities.
HameedAhmed - PeerSpot reviewer
Joint Director at PAA
Security threats have been reduced through seamless deployment and strong integration with other tools
I have used Fortinet FortiWeb's integration features. We have easily integrated all of the applications with the product. Most of the applications we are using are in-house built. My technical team is looking after the best features. I have not used it extensively for maybe two and a half years. I have been involved in the installation, but I am not actually using the product. I work with it from time to time but not extensively. I would assess Fortinet FortiWeb's adaptive machine learning and artificial intelligence as having new patches installed regarding artificial intelligence, but when we bought it, I think the learning feature was there. Now they have installed artificial intelligence features through patches. We have a complete portfolio of Fortinet in our organization, including FortiMail, Fortinet FortiWeb, and FortiGate, along with multi-factor authentication. All of the products are from Fortinet. Fortinet tools integrate with each other and work in conjunction. I think Fortinet FortiWeb has helped us meet regulatory compliance because we are not a regulatory organization, but our sister organization is regulatory. We have regulatory compliance with the International Civil Aviation Authority, whose audit teams have checked our data center and these security products, and they are satisfied with us. The question about leveraging Fortinet FortiWeb's automated policy management does not pertain to my domain because I am not so technical, but I am in a management role now. My engineer is more technical than me. I would rate this product an eight point five out of ten.
