Cloud applications have gained stronger protection and real-time defense against web attacks
What really stands out for me in terms of advantages of F5 Silverline Managed Services is that in a single cloud platform, I can protect my web applications against attacks. I can also use my load balancer in F5 because they are providing and acting as a load balancer too, and they will support the volumetric and DDoS attacks and malicious attacks. Regarding the real-time threat intelligence feature, I do use this aspect in F5 Silverline Managed Services. It blocks malicious IPs or bad IPs for my server, protecting against my applications. For example, if someone is a bad actor trying to access via a malicious IP, I can block it because the threat intelligence has the capability to block the malicious IP. The adaptable and flexible security impacts threat response time positively. It is effective because it blocks my malicious traffic. Whenever I face issues related to that application, it automatically routes my traffic to act as a proxy and routes my traffic to their scrubbing center, especially in case of any volumetric attack.

Advanced threat protection has reduced financial risk and improves application security visibility
The issue I have with Fortinet FortiAppSec Cloud is that the real-time analysis is not robust; I am unable to see all the logs of everything that happened, including what is passive. It only logs when there are suspicious activities, which means if something is not considered suspicious by Fortinet, I will not see the full picture. That is a disadvantage because it will not log unless it identifies an IOC or attacks, meaning I cannot see traffic information in a way that helps build more intelligence. The biggest issue I have with Fortinet FortiAppSec Cloud is that the logging is not as extensive as I would prefer. For instance, if there was an issue two days ago and Fortinet FortiAppSec Cloud did not mark it as a concern, I will not see any information about that, making it challenging to explain to customers if their request did not reach us. It hampers visibility from an API perspective. They need to enhance monitoring and logging to be more extensive and capture even passive activities. The AI integration in Fortinet FortiAppSec Cloud is still new. The generative models are good, but there is much work left to improve. It is not as intelligent as it could be; thus, enhancements around the AI co-assistant would be beneficial. Additionally, logging and monitoring need improvement as I can capture traffic and investigate offline on my Fortinet firewall, including full traffic view, but Fortinet FortiAppSec Cloud currently focuses only on security concerns, which does not give the complete picture.

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 features are the configuration and configuring the process."
"The 30% efficiency improvement has definitely resulted in increased revenue for us, and with our website performing much better, I am able to achieve faster cycle times in terms of lead to conversion."
"F5 technical support is really good; it is better than A10."
"The initial setup is very straightforward."
"The product’s UI is easy to understand."
"The most important feature is that they have seven firewall protection, to protect our web servers."
"F5 Silverline Managed Services has a very positive impact on my organization."
"The stability of the solution is very good."
"We have seen a reduction in incidents and a good return on investment from Fortinet FortiAppSec Cloud, with our return on investment around 60%."
"My favorite Fortinet device is the FortiGate next-gen firewall itself; it is a complete suite with intrusion prevention, intrusion detection, anti-malware, anti-DDoS, and SD-WAN functionalities."
 

Cons

"In terms of the scalability, this part is always so confusing because they are checking for packet count. Also, after an attack, they said that the throughput must be from gigabits but then I check my bandwidth and it is already done in gigabits. So it is a little bit confusing."
"The price of F5 Silverline Managed Services could be better, they are not very flexible."
"F5 Silverline Web Application Firewall, being a new product in the market or comparatively related to a new product, currently supports less number of PoPs."
"We'd like more AI to be used. Right now, they don't use it enough."
"We have complaints about the reliability of this solution."
"One thing that was a hassle for us regarding F5 Silverline Managed Services was the deployment of this particular software."
"There is a lot of room for improvement with their tech support. I am not sure F5 Silverline Managed Services can be classified as having tech support."
"We are doing a lot of automation, so I find the APIs are not very easy to use. So the current automation is not that good for F5 at the moment."
"Real-time traffic analysis has posed an issue for us because we did not see logs for legitimate traffic."
"The issue I have with Fortinet FortiAppSec Cloud is that the real-time analysis is not robust; I am unable to see all the logs of everything that happened, including what is passive."
 

Pricing and Cost Advice

"The product’s pricing is reasonable."
"The price of F5 Silverline Managed Services could be reduced."
"F5 Silverline Web Application Firewall works based on your bandwidth. They look at the clean bandwidth and do the pricing. 20% of a total pipe would be a clean bandwidth. The list price or a non-negotiated price for F5 Silverline Web Application Firewall would be around $2,200 per application per year for everything that you need. When you get into an enterprise kind of a setup, they negotiate this to the last bit. I would easily take 20% on that, which would be the cost, but it should cover all your Advance WAF features, bot protection, tech campaign, etc. It is built as a package and gives you most of the capability. You don't get the mobile SDK, which is an additional license. Mobile SDK is required only if you're buying or if you have a mobile application, and you are going to instrument F5 or Imperva into your mobile appliance. This anyways would be an additional module. It doesn't come within the WAF, but it is a WAF feature."
"The price of F5 Silverline Managed Services could be better, they are not very flexible. The price of the solution is based on the requirements of the enterprise."
