Executive SummaryUpdated on Jan 1, 2025

Fortinet FortiWeb and F5 Silverline Managed Services compete in the web application firewall (WAF) and security services category. Fortinet FortiWeb seems to have the upper hand due to its comprehensive features and cost-effective pricing, making it more adaptable for complex security needs, while F5 Silverline offers robust but costly services.

Features: Fortinet FortiWeb offers extensive features like application control, web filtering, and virtual patching. It also includes zero-day protection, antivirus, and integrated security with its broader Fortinet suite. F5 Silverline Managed Services focuses on application delivery and security management, offering robust support, though it lacks advanced load balancing and security fabric integration found in FortiWeb.

Room for Improvement: Fortinet FortiWeb could enhance its update processes, improve its GUI, and expand support for newer technologies. Additionally, it would benefit from better threat detection and more detailed reporting. F5 Silverline Managed Services needs to expand feature depth, improve AI integration, and offer more flexible pricing. An increase in global PoPs would also enhance its service availability.

Ease of Deployment and Customer Service: Fortinet FortiWeb provides flexible deployment across on-premises, hybrid, and cloud environments, though some users find its interface complex. Its technical support is generally strong, with occasional delays. F5 Silverline supports various deployment models, praised for its easy setup and high-quality customer support, albeit at a higher cost.

Pricing and ROI: Fortinet FortiWeb is competitively priced and considered cost-effective, offering a good ROI, especially for integrated security needs. In contrast, F5 Silverline Managed Services tends to be more expensive, with pricing linked to application and bandwidth usage, offering extensive capabilities but at a premium price point. User perceptions of ROI are mixed, influenced by these costs and performance factors.

Owner at Tech Exchange

It's easy to set up because you point the DNS to it, and it's working in under 15 minutes

Cloudflare is highly scalable. Cloudflare is a system with a web portal that the end users like me see. It's a console where we can adjust the DNS, caching, and security features all in that console. Cloudflare owns thousands of servers across the world that cache the data. It's a powerful solution. When clients sign up for Cloudflare, they're getting this monster content delivery network, security, and a web application firewall in one. It's all rolled into one, and it's massive. Unless you have your website hosted on a massive hosting provider, there's no way that you can deliver the amount of data that Cloudflare can provide to the end users. If you have static content, there's no way that you can ever match what Cloudflare can do. Obviously, there are competitors to Cloudflare that do the same, but I'm saying other types of solutions. Let's say you go with F5. Great, that's on-prem. That's in your colo. You can't deliver as much data to the internet as you can with a CDN. You don't have to spend $20,000 on a net scaler, F5, or whatever Cisco's selling now. You don't have to buy that. You pay them $50 a month or $150 a month. It's totally worth it because even in five years, you'll never get the performance value, not just the actual ROI. You have to consider how much throughput you can get with Cloudflare.

Mitigates more bot activity when defending web applications than any other vendor but comes at a price

F5 Silverline Managed Services is expensive. You do get world-class quality of mitigation, but I think it is still pricey. You can find similar services, potentially of slightly lower quality, from other vendors like Cloudflare or Akamai for about half the price. When you compare what you get for the money you spend at Cloudflare or Akamai, you do get less protection but you are not dishing out too much for it. On the other hand, at F5 Silverline Managed Services, you do get better protection but, but you are paying double for it. We have had mixed feedback from our clients about this. Most of them would rather pay less for a bit of a lower-quality defense than overshoot their budget. The most common piece of feedback we receive is that the difference in protection levels is not reflected in the price.

Even if an attacker detects the IP address, they can't connect directly to the server due to FortiWeb

The xFF, or X-Forwarded-For feature, IP reputation, and protected hostname. We can block access using the IP address, so no one can connect to our web server or website using the real IP. They need to use the FQDN instead. Even if an attacker detects the IP address, they can't connect directly to the server due to FortiWeb and the option to protect the hostname. All traffic passes through FortiWeb. Machine learning capabilities in FortiWeb: I don't use machine learning all the time. In the initial phase of FortiWeb deployment, we use the learning process to detect the traffic passing through FortiGate to our website.

Quotes from Members

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

Pros

"The simplicity of the overall dashboard makes it a great product for a user like me who has less understanding of the internet than a developer or other more technical people. It gives me peace of mind. I also love the easy customization of the Page Rules."

"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."

"The solution automatically detects and responds to certain types of traffic based on geolocation."

"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."

"Centralized, full-featured DNS."

"The most valuable feature is its usability."

"Its most significant benefit to date is the speed with which it refreshes DNS records on the internet once you change it. If you are changing a website or registering a new record, it is very quick."

"There are key things that are used for our enterprise customers, such as Lambda and DNS."

More Cloudflare pros

"The most valuable features are the configuration and configuring the process."

"F5 technical support is really good."

"The stability of the solution is very good."

"It's a good front end for public infrastructure"

"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."

"The most valuable feature is flexibility."

"The most valuable feature of F5 Silverline Managed Services is the benchmark performance."

"The product’s UI is easy to understand."

More F5 Silverline Managed Services pros

"The customers are very happy with this solution because of two things. First, the IPS integration with a web application is very tightly done on Fortinet. Second, the ease of use is there. The management interface or the GUI interface is very easy to use, configure, and manage. These are the two main valuable features. It supports integration with other Fortinet products. It also integrates very well with the firewall and sandboxing technology. They already have enough integration with different technologies. They have got a complete tech intelligence view of the whole product."

"It is cost-effective compared to other solutions."

"It's stable and works efficiently against OWASP Top 10 attacks."

"The initial setup is pretty straightforward."

"You have the ability to control everything from one single dashboard."

"The GUI makes it easy to scale in terms of learning and utilization."

"Fortinet is a great SD-WAN player when it comes to security capabilities."

"Both the internal firewall management and the cloud can be managed by a single console."

More Fortinet FortiWeb pros

Cons

"An integrated SSO feature would be useful for Cloudflare DNS."

"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."

"There are some issues with the CDN services."

"The solution could be more user-friendly."

"We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."

"There should be a specific price list for enterprise-level customers."

"We are a product integrator and reseller, and we would like to have a better partner relationship, similar to a channel sales relationship. Sometimes we are on our own or get diverted by Cloudflare because they have direct sales, which competes with us and makes it difficult to build a relationship with this company since we want to be an MSP or a managed service provider for the solution."

"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."

More Cloudflare cons

"Sometimes tech support can be slow. They take more time assigning engineers to complex issues, however, they resolve the issues by joining me to fix them."

"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."

"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."

"F5 Silverline Managed Services can improve by reducing the price."

"There is room for improvement in the stability of the solution."

"F5 Silverline Managed Services can improve by adding features that Palo Alto has."

"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."

"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."

More F5 Silverline Managed Services cons

"The Layer 7 DDoS attacks need improvement, it could be better."

"The product's scalability could be better."

"We use Kubernetes, so I would like to have a plugin to configure FortiWeb Cloud automatically using Kubernetes Ingress. That would reduce the complexity of setting up an Ingress object in Kubernetes. Some competing solutions help you configure Ingress and Kubernetes automatically."

"Their documentation is fairly complete, but it's sometimes a little bit difficult to search for exactly what you're looking for to resolve an issue. There have been times when we've gone to try to search for areas that we needed to get information on, and it has not always been extremely clear exactly how a particular thing needs to be set up."

"Centralized configuration using FortiManager – like what exists for NGFW FortiGate appliances - would improve the configuration."

"For advanced users, it would be really useful to have access and the ability to manipulate packets. If we can access and manipulate the contents of packets, even encrypted packets... that would be powerful. Since we're looking at packets arriving at our network, we would have the private key to access those packets and their information."

"I would like to see more improvements with respect to threat intelligence."

"The integration with other products should be improved."

More Fortinet FortiWeb cons

Pricing and Cost Advice

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."

"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."

"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."

"We are using the free tier of the solution."

"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."

"Cloudflare's pricing is not much higher and is good for middle-level organizations."

"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."

"A free version of the solution is available."

More Cloudflare pricing and cost advice

"The product’s pricing is reasonable."

"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 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."

"It is an expensive suite and it is an expensive solution, but it is a manageable one for an enterprise."

"The price is competitive."

"So far, I have been pretty pleased with the way it's priced and licensed. The way it's done makes it easy, especially for an organization like us, so I've been pleased with the way it's priced and licensed right now."

"When I use any other firewall, I have to take a license. It could be a perpetual license or subscription-based. In both cases, we have to pay some amount in advance, whereas in the case of FortiWeb, when using it as a service, I am paying half a dollar only for the domain name, and then I am paying based on the traffic or the number of requests."

"Its subscription prices are cheaper, and it is not very expensive. From a price perspective, Fortinet is a very well-known security vendor. Subscriptions are very simple. They have a couple of licenses on an appliance, and that's it. The cost is not that big. One license is 40K, which they give with all the products. Another one includes the subscriptions for threat prevention, IPS, sandboxing, etc, which is more than enough."

"The price of Fortinet FortiWeb is reasonable. This is one of the key factors of why we use this solution."

"There are no licensing costs."

"Cheaper than others."

Reviews from real users

“Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare
comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and
an SSL certificate automatically protects your website. If you have a connection between your
website and your host, the server, Cloudflare, and the host, you don't necessarily need a
certificate.” Spencer M., Owner at Tech Exchange

“What I like best about Cloudflare is that my company can use it to trace and manage
applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare
also sends you a link to check your equipment and deployment and track it through peering,
so it's a valuable tool.” Daniel P., Network Engineer at Ufinet

“The most valuable feature of Cloudflare is the GUI. You are able to control the solution very
well through the interface. There is a lot of functionality that is embedded in the service.” PeerSpot user, Competence Center Manager at a tech services company
