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.

The solution enables seamless security management and fosters a learning environment
Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions. For the solution stopping us for e-learning, I appreciate the concept yet need more resources or courses in Mexico, preferably in Spanish. Certifications are easy, however, I require more real-world environments and instructors.

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 allows us to self-host services such as Rocket.Chat and Node-RED, in high-availability mode, thanks to round robin DNS which allows us to share one hostname between our two locations."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"Even when there is a high load on our servers, Cloudflare is able to cache the data and serve it to users, ensuring they can still access the website."
"The most valuable feature is the web application firewall."
"The most valuable feature is its usability."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"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 overall experience with Cloudflare is positive, with a rating of eight out of ten."
"Cloudflare is simple to use."
"I'm very satisfied with the environment and the dashboard."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"It is a stable solution."
"This solution is easy to understand and easy to configure."
"Cloudflare DDoS mitigates DDoS attacks."
"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."
"Clover is the best product globally."
"The most valuable features are the configuration and configuring the process."
"The best advantage of F5 Silverline Managed Services is that it is easy to use."
"F5 technical support is really good."
"The most valuable feature of F5 Silverline Managed Services is it becomes similar to a distributed architecture."
"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 of F5 Silverline Managed Services is the benchmark performance."
"The stability of the solution is very good."
"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."
 

Cons

"In the last two years, there has been a certain amount of downtime when using the VDM."
"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."
"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 doesn't have a reverse lookup. We can only do a DNS lookup to get the IP address from the hostname. It doesn't work if you want to look up the hostname from an IPA address."
"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"The product needs to improve its automation."
"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."
"DNS Management."
"There are premium tier live service and lower tier live service, so we opted for the lower tier. But there is no medium tier where we pay a little extra and get a bit more service. So if that can be improved."
"Our subscription plan for the solution has a limitation of bot signatures."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The response time for support must be reduced."
"Cloudflare DDoS has poor technical support."
"Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions."
"They don't have a person to provide support for customers using the solution under their free plan."
"For the topic of improvement, providing some training material is one of my suggestions."
"The navigation is difficult to use."
"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."
"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."
"I just hope the price can be cheaper."
"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."
"Automating processes could enhance F5 Silverline Managed Services."
"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."
 

Pricing and Cost Advice

"We don't have any issues with the price."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"The product's pricing is cheap."
"There are no additional costs beyond the standard licensing fees."
"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."
"I give the price a five out of ten."
"The price is reasonable."
"We are using the free tier of the solution."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The solution is not that expensive."
"The prices are slightly expensive."
"My company has to make yearly payments towards the licensing costs attached to the solution. There are no hidden charges apart from the licensing costs of the solution."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The pricing of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."
"Cloudflare Zero Trust Platform's pricing is good."
"The solution's pricing lacks transparency."
"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."
"The product’s pricing is reasonable."
