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.

Makes it easier and quicker to spin up services when we deploy applications
The most valuable aspect is the ability to customize the types of load-balancing scenarios needed for customized applications. Some of the load balancers on the market today are strictly out-of-hand load balancers for SSL or HTTP. Radware Alteon is most useful for customizing in-house applications based on ports and protocols. Another great feature is integrated application protection. There are many features you can activate. Some of them are add-ons, such as WAF protection, DDoS, rate-limiting, and connections-per-second per application. We also use Radware where we do all the programming.

Quotes from Members

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

Pros

"The solution provides good load balancing and protection against DDoS attacks."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"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."
"The solution offers the flexibility to control configuration rules."
"It is a fast and secure DNS."
"DDoS attacks target unprotected machines. Cloudflare detects and stops these attacks using internal systems. It identifies incoming DDoS attacks, issuing challenges or blocking them immediately."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"Its flexibility is the most valuable because it is a managed service. The good part is that you don't need to set it up. It just needs DNS routing, which is the easiest thing. Our client had Akamai for certain websites because they were using CDN features. They had NetScaler on the internal zone, F5 AWAFs on the data centers, and no WAF at all in the cloud. One of the main activities of the project was to move all these policies into a single WAF so that we could control and use that as a choke point. That exercise itself was very easy because it was a managed service and F5 Silverline Web Application Firewall does that for you. That's the best thing about F5 Silverline Web Application Firewall. It is easy to apply policies on-premises. If you have AWAF on-premises and you want to replicate some policies on F5 Silverline Web Application Firewall, other than the policies that it applies by itself, it is easy because you have a team that supports it. F5 Silverline Web Application Firewall works perfectly fine. It pretty much does everything that an Advanced WAF on-premises should do."
"The initial setup is straightforward."
"The most valuable feature of F5 Silverline Managed Services is its cloud-native functionality and the high level of protection it provides."
"The most valuable feature of F5 Silverline Managed Services is it becomes similar to a distributed architecture."
"F5 Silverline offers load balancing, flexibility, and reliability."
"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."
"We have a lot of businesses that we put behind this solution, and it has really helped us in terms of monitoring the logs and incidents."
"The initial setup is very straightforward."
"Security is one of the most valuable features that I like. It is easy to use and easy to configure."
"The link load balancing is a great feature."
"I find the best features to be the flexibility and ease of use. The configuration is very straightforward."
"The product offers high availability."
"The features that mitigate attacks are very valuable."
"The device blocks threats and allows legitimate users to work correctly."
"The integrated application protection provided by Alteon is very good. It really helps to avoid false positives in some cases. It provides important granularity to avoid a situation in which security or cybersecurity scenarios escape us."
"Radware has been characterized by being extremely robust. This gives us the confidence to offer our users a continuous service."
 

Cons

"The analytics, basically the dashboard, doesn't have much to it."
"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."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"Cloudflare should add more documentation and pricing to the cloud version."
"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."
"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."
"The documentation could improve for Cloudflare DNS."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"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."
"F5 Silverline Managed Services can improve by adding features that Palo Alto has."
"There is room for improvement in the stability of the solution."
"Improvements could include the creation of highly optimized profiles, optimization deployments, and compression profiles for better performance."
"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 need to have support for cloud protection, which is not offered by this solution."
"F5 Silverline Managed Services can improve by reducing the price."
"You need to have Linux knowledge in order to use the shell."
"Radware LinkProof's marketing efforts need improvement to raise awareness about its capabilities and compete effectively in the market."
"I would like to see future enhancements in security, specifically in threat protection."
"We’d like the solution to include more security features in the standard license."
"I would like to see an improved community presence, similar to the one for their main competitor, F5."
"It can be improved by combining the web application firewall (WAF) facility."
"There is room for improvement in reducing the number of false positives I receive. We could benefit from more configuration options to avoid these false positives, which can be overwhelming for a security analyst."
"The solution lacks HA configuration."
"The service could be improved by better customer support."
 

Pricing and Cost Advice

"The cost primarily depends on the size of the organization."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"We are using the free version."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"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."
"I give the price a five out of ten."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"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."
"The product’s pricing is reasonable."
"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 price of F5 Silverline Managed Services could be reduced."
"Our government agency opted for Radware Alteon due to its affordability and efficiency. While I can't say precisely how much it costs the organization, the price per device. In India, we always look for affordable products, so I assume Alteon is cost-effective because the government chose it."
"The pricing is better than the competition. It is getting more pricey as the years go on, as more people are migrating to it, and as the technology gets better."
"The cost of Radware Alteon is mid-ranged."
"We have three-year contract with Radware. It is beneficial to have a longer-term contract because you can obtain more discounts. It seems to be a much cheaper alternative."
"Alteon's price is excellent compared to other solutions. F5 costs around twice as much. We still have about three years left before this hardware reaches the end of its life. We're migrating to the cloud, and phasing some of this out, but it's nice that they've given us a long window to keep their hardware in place."
"It is cost-efficient. That is why we have gone with Alteon. As a product, it is efficient and robust. We have not faced any issues with the device."
"The solution is cost-efficient."
"It is not the priciest and it is not the cheapest. For our solution, it was right in the middle of price performance."
