Advanced security reporting has protected high-traffic betting platforms from constant attacks
I don't see room for improvement to Cloudflare Web Application Firewall. One thing I don't know much about because we have a dedicated IT team for that, and I'm not involved with Cloudflare much anymore. But if I were to compare them to F5, I would like to see more features that F5 offers. F5 has an option to bring the whole infrastructure, the whole WAF and all their packages, Bot Management, and everything else on your infrastructure. You need to install certain services from their side, and then you can choose if you would like requests to hit your servers immediately or if requests need to be proxied through F5 backbone. That would be a nice addition because we have 90% of the traffic as legit traffic coming from whitelisted servers. If it comes from whitelisted servers, I don't need to go every request through the backbone; I could easily just IP whitelist everything. Then I could maybe have Bot Management on my infrastructure that drastically reduces the price of Cloudflare. I would like to see Push CDN more improved in the next release of Cloudflare Web Application Firewall. And maybe something similar to Pushpin that Fastly has, which is an option where you can push messages that then can be scaled globally over the network. From our perspective, if we have a listener that listens for stock updates, I would just need to have one processor that pushes those updates to the Cloudflare API, and then Cloudflare would broadcast that message to all listeners. Cloudflare will check the order of the message, and if you, as a customer, are not connected or have some kind of network issue, when you reconnect, you will receive the latest state and missing updates.

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.

Helps us to monitor attacks to our sites and prevents a lot of them
Set up Wallarm as a reverse proxy. Do not replace your web server. Use Wallarm first in monitoring mode, then learn from Wallarm which type of request is false positive and which type of request is not. This process takes a couple of weeks for very highly-loaded web applications (few millions of unique visitors in one month). Then you can turn Wallarm into blocking mode and everything will be fine. Do not forget to build a monitoring system, the wave, and API for it. Before we started using Wallarm, I already knew Ivan (CEO) and Stepan (COO) from a couple of years before. Ivan had his own security company and Stepan was working on a Russian security magazine called Xakep. They told us that they wanted to create a new WAF and already had a working version of it. They asked me to test it. We did tests, and it was really good. After few month after testing, we signed an agreement. Our choice was made not because we knew these guys for a long time, but because the product was really cool and we were glad to start using it as one of the first on the market!

Quotes from Members

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

Pros

"Technical support has a very fast response time and they are helpful."
"The most valuable part of the solution for us overall is exactly that it is a Software-as-a-Service product."
"This solution does a good job of preventing web application attacks, SQL injections, and cross-site scripting attacks."
"It is a SaaS solution unlike much of the competition."
"This is a good product; it's reliable and scales well."
"Very glad the WAF rulesets works out of box, and requires very little tuning or maintenance."
"The security features are valuable. The particular feature we use is called OWASP."
"The solution protects our application, which runs on the HTTP protocol, from DDoS attacks."
"F5 technical support is really good; it is better than A10."
"The initial setup is very straightforward."
"The best feature F5 Silverline Managed Services offers is 24/7 SOC co-management, which has drastically helped us during major DDoS attempts or web scraping incidents by handling the triage and mitigation entirely and reducing our MTTR from many hours to a couple of hours or minutes."
"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."
"F5 Silverline Managed Services has a very positive impact on my organization."
"F5 Silverline takes fewer resources to operate."
"The most valuable features are the configuration and configuring the process."
"Most vendors fulfill the requirements for standard DDoS protection, but F5 Silverline Managed Services has a better understanding of defending web applications like HTTP and can mitigate more bot activity than any other vendor."
"Vulnerability scanner and WAF are valuable features."
"They are the only solution that fits our success criteria and business objectives: WAF must have a low (<5%) false negative rate and be ready to protect from all well-known web attacks."
"The most powerful feature is the ability to first learn what type of query to make to your web application when it is attacked and what type of query creates a false positive to your app."
"Helps us to monitor situation in regards to attacks to our sites and prevents a lot of them."
"With active threat detection, we are no longer over-swamped with tons of useless events."
"Perimeter control and active vulnerability scanner are the most valuable features."
 

Cons

"Their documentation could be better. They don't have documentation that explains everything well."
"The blocked logs are difficult to read at times."
"A key challenge arises when dealing with numerous integrations with HVAC systems. Depending on the specifics, there might be some configuration mismatches, which necessitate specific support."
"It would be ideal if the solution offered better log integration and more integration with different platforms."
"Cloudflare Web Application Firewall should include port forwarding features."
"The learning curve was steep initially."
"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."
"The solution's learning curve can still be further reduced"
"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."
"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."
"One negative aspect is that the product is expensive."
"We'd like more AI to be used. Right now, they don't use it enough."
"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."
"The price is high in comparison to other products."
"F5 Silverline Managed Services could be improved with more intuitive dashboards, a self-service option for respondents, localized support, and better pricing since I think it is high."
"There is room for improvement in the stability of the solution."
"Technical support is 6 or 7 out of 10. Sometimes we have had trouble with communication and understanding."
"There were several stability issues during the first pilot."
"The biggest problem for us was the stability and speed using the first version of Wallarm. Now, it is fine."
"It needs more customization in PDF reports."
"Wallarm uses a learning mechanism to detect attacks and to avoid false positives. If Wallarm blocks some illegitimate request, then you can go to the management console and mark this request as false positive, but sometimes this does not work properly."
 

Pricing and Cost Advice

"The annual licensing fee is $10,000 USD."
"The solution's pricing option needs to be more transparent for enterprise clients."
"What's my experience with pricing, setup cost, and licensing? I believe the pricing is not the best, but it's reasonable and acceptable. We also use the McAfee system in parallel. In terms of pricing, its okay - not great, but not bad either. It falls in the middle, which is acceptable. In terms of support licensing, last time, we were searching for a solution, and we considered products from resellers rather than directly from the cloud provider. However, the pricing we encountered was exceptionally high. As a result, we are inclined to select support from the reseller."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"The solution is expensive."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"It is not too pricey."
"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 is reasonable."
"​Pricing must be cheaper than the competition and the licensing must be good.​"
