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

"Cloudflare has many features."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"Cloudflare makes it easier for me to handle and set up DNS for multiple users and multiple clients, and basically go in and access their account, make the changes they need, and it's a one-stop shop."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"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 tool is user-friendly."
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"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."
"The product is easy to use."
"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."
"I am impressed with the product's multiple features like security."
"The solution operates smoothly at its baseline level, and we do not encounter any issues at that level."
"The product has a good mechanism to analyze trends and trigger events."
"It is integrated with AWS. So, it gives you a good first step."
"The stability of the solution is very good."
"F5 technical support is really good."
"The most valuable feature of F5 Silverline Managed Services is it becomes similar to a distributed architecture."
"The most important feature is that they have seven firewall protection, to protect our web servers."
"F5 Silverline offers load balancing, flexibility, and reliability."
"The product’s UI is easy to understand."
"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 of F5 Silverline Managed Services is its cloud-native functionality and the high level of protection it provides."
 

Cons

"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"Cloudflare's console should be made more user-friendly."
"There might be helpful if there was some web application firewall feature."
"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."
"The product is expensive."
"There is an area for improvement regarding health checks. AWS Shield does not come with its own health check functionality."
"Perhaps the time required to detect anomalies can be reduced."
"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."
"AWS Shield has limited coverage as it only protects against common and high-volume network and transport layer attacks, such as SYN floods."
"AWS Shield Standard requires improvement, particularly regarding its dashboard since it currently provides limited coverage against comprehensive DDoS attacks."
"F5 Silverline Managed Services can improve by adding features that Palo Alto has."
"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."
"Automating processes could enhance F5 Silverline Managed Services."
"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."
"The navigation is difficult to use."
"There is room for improvement in the stability of the solution."
"The price is high in comparison to other products."
"The price of F5 Silverline Managed Services could be better."
 

Pricing and Cost Advice

"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."
"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."
"We are using the free version."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"A free version of the solution is available."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their 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."
"That is one of the great features. I was able to access the majority of the features and services for free."
"We pay $3000 per month for the solution."
"The tool's pricing is good."
"The cost depends on traffic each month, so on average, it costs us between US$200 and US$300 per month."
"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 tool is cheap."
"The product’s pricing is reasonable."
"The price of F5 Silverline Managed Services could be reduced."
"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."
"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."
