Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.
Ifeanyi Stanly Nwokoro - PeerSpot reviewer
Has ensured ongoing protection against cyber threats and provides timely automated response while requiring improvements in cost structure and performance transparency
Business inherently involves risk, and it's important that services continue to improve. AWS Shield is not an exception. Regarding advanced Shield protection pricing, there should be cost protection for most DDoS events. The pricing model should be based on service usage rather than a flat monthly rate. The advanced technique package, while premium and not available to every user due to cost implications of $3,000 per month, offers valuable features including real-time attack visibility and 24/7 access to the DDoS response team. Integration is paramount, particularly with the Web Application Firewall's rule-based blocking paradigm that helps in balancing routes, especially route 53 and the global accelerator. AWS Shield uses pattern recognition to analyze traffic, and certain attributes are immediately intercepted. The assessment process is profound, and the service maintains consistent availability. From a software perspective, there are improvements needed regarding antivirus and network security. Additional engineering improvement requirements would benefit AWS Shield.

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.

Quotes from Members

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

Pros

"Generally, I am satisfied with this product."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"It's a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"The solution is very good at mitigating threats."
"The solution operates smoothly at its baseline level, and we do not encounter any issues at that level."
"It is integrated with AWS. So, it gives you a good first step."
"I am impressed with the product's multiple features like security."
"It is quite scalable, and we have not faced any issues with its scalability."
"AWS Shield is aligned with the web application firewall (WAF), and they work seamlessly together, primarily working with Elastic Load Balancer, CloudFront, and Route 53 for CDN and DNS services protection."
"The solution's ease of use is the most valuable feature."
"The product has a good mechanism to analyze trends and trigger events."
"I recommend AWS Shield because it has proven helpful in tracking DDoS attacks within both my past and present environments, and without AWS Shield, a business could face potential losses, as this tool helps in identifying and mitigating fake traffic that disrupts applications, ultimately supporting business continuity."
"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 most valuable feature is flexibility."
"It's a good front end for public infrastructure"
"The most important feature is that they have seven firewall protection, to protect our web servers."
"The product’s UI is easy to understand."
"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 straightforward."
"F5 technical support is really good."
 

Cons

"The solution could be more user-friendly."
"Technical support is not well developed. While there are good engineers, Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"The product support needs to be accessible from more places, a wider area of coverage."
"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"They lack a good way to manage DNS as a company, since everything is relegated to single account logins until you get to the higher levels. They have come out with a paid feature to remedy this, but I have not had a chance to fully review it yet to know if it fixes the access problem."
"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."
"Cloudflare's console should be made more user-friendly."
"AWS Shield has limited coverage as it only protects against common and high-volume network and transport layer attacks, such as SYN floods."
"Perhaps the time required to detect anomalies can be reduced. Presently, it takes some time to determine whether a situation is normal or abnormal."
"The product should give users more flexibility to customize their security policies according to their requirements."
"The product needs to improve its logs and reports to make it read better."
"The management of it is a bit hard. If you don't engineer it on the front side, it is hard to go back in and change it. It could be improved in terms of architecture requirements and then ongoing support requirements as a secondary component to it. People tend to set up things like this, and they just expect it to work without the care and feeding that needs to go back into it either from an application team or a network environment team."
"We end up having to pay extra for features that AWS adds that we don't need."
"Perhaps the time required to detect anomalies can be reduced."
"AWS Shield Standard requires improvement, particularly regarding its dashboard since it currently provides limited coverage against comprehensive DDoS attacks."
"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."
"The price of F5 Silverline Managed Services could be better."
"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 is high in comparison to other products."
"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."
"You need to have Linux knowledge in order to use the shell."
"Automating processes could enhance F5 Silverline Managed Services."
"The navigation is difficult to use."
 

Pricing and Cost Advice

"There are no additional costs beyond the standard licensing fees."
"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."
"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 price is reasonable."
"The price of the solution is expensive."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"The tool's pricing is good."
"The tool is cheap."
"The cost depends on traffic each month, so on average, it costs us between US$200 and US$300 per month."
"We pay $3000 per month for the solution."
"It depends on your subscription level and the volume that you're spending with AWS. So, it is very relative to the consumption alignment in your subscription level. It is a well-constructed, scalable pricing option, but it is relative to how much you're spending on AWS. Because the more you spend, typically, the more you get off on services like this. I find it to be comparable to other solutions."
"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."
