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.

Reliable protection and smooth setup enhance company security
Currently, I have two firewalls, with one located in Sorocaba, model 90D, and the other in São Paulo, model 30D. They are connected by VPN. I use the firewalls for VPN and final protection for my company, and my equipment is maintained by an internet company called Multiprox The equipment works…

Quotes from Members

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

Pros

"This is a good product that you can rely on."
"If you are looking for web security and don't have any solution, just try it."
"My advice to others is this is a very reliable solution."
"F5 Silverline offers load balancing, flexibility, and reliability."
"F5 technical support is really good; it is better than A10."
"The most valuable feature of F5 Silverline Managed Services is the benchmark performance."
"The most important feature is that they have seven firewall protection, to protect our web servers."
"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."
"The protection resources and the support are valuable features of the solution."
"The pricing of this solution is better than that of Cisco and other software on the market, which are very expensive."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us, and this is important."
"Compared to other DDoS mitigation solutions with similar deployment, FortiDDoS does not require a 24x7 NOC and has lower TCO."
"It is a user-friendly product in terms of monitoring and updating policies."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"The product's initial setup phase was really easy."
"I find the interface easy to use."
 

Cons

"I just hope the price can be cheaper."
"The product could be improved on the global load and the integration with other solutions like Cisco and Dell EMC."
"One negative aspect is that the product is expensive."
"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. They should introduce more PoPs. The current number of PoPs that they have is around 10 or 12, which is still relatively less as compared to 2,400 plus PoPs that Akamai offers. The user latency or the number of hops a user needs before reaching the actual web application is less in Akamai because it has its internal fabric to route the traffic. They need to spin up more data to increase its traffic handling capability. They can also include the bot detection capability, though it is a pretty advanced functionality. If they could include DataDome like functionality, that is, bot prediction, then F5 Silverline Web Application Firewall will be top-notch in the market."
"We'd like more AI to be used. Right now, they don't use it enough."
"We need to have support for cloud protection, which is not offered by this solution."
"I think the management portal and the visual dashboard of F5 Silverline Managed Services could use an update."
"The product could be improved on the global load and the integration with the other solution like Cisco and Dell. As a representor of the operation, we prefer to have one platform which can accommodate all type of integration. We are also looking for more improvements in the security policy configuration."
"Alerts and reporting features must be improved."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The product’s pricing needs improvement."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"Technical support isn't too good with Fortinet. They could be more responsive and helpful overall."
"The web interface could be much better."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"The solution can be a little more user-friendly and it can be more affordable."
 

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."
"The product’s pricing needs improvement."
"The solution is reasonably priced."
"It's quite pricey."
