Featured Reviews

Carlos Alam Hernandez Baruch - PeerSpot reviewer
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.
Nick Wilsdon - PeerSpot reviewer
An easily scalable and stable product that provides exceptional support
The product should provide improved bot detection and management. The product should also provide support for code management. Everybody working in CDN is currently looking for ways to better manage code deployment with various authorization levels and synchronization with our lower environments. Matching up what's happening in CDN with what's happening on the origin regarding testing would always be useful.
ADRIANA SALDARRIAGA TOBON - PeerSpot reviewer
Client experience and cybersecurity have improved with an easy setup
The solution is valuable for client experience, especially in the financial sector. The most important feature is cybersecurity. The pricing is good, but the functionality is the most important aspect for clients. The solution is easy to deploy and requires only one person to set up, making it easy and quick. Overall, the ease of use and the fact that it meets client expectations are major positives.

Quotes from Members

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

Pros

"The web application firewall brought us good security and a view of the accesses/blocks of the entire domain and subdomain that were accessed both by region (country) and IPs."
"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."
"The tool is user-friendly."
"The solution is stable, and the DNS servers are simple to use."
"The most valuable feature is the web application firewall."
"The solution provides good load balancing and protection against DDoS attacks."
"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."
"The most valuable feature is its usability."
"Support is good; the product works as advertised. We have a Slack connection with them. So we can basically ask for help, live, engage, and ring when they respond. Very quickly."
"Its initial setup process is straightforward."
"The product helps our organization to access sites located in different regions quickly."
"The product's initial setup phase is straightforward."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"Rate limiting is a good feature that protects from volumetric attacks."
"Compute@Edge features are valuable to me."
"The drill-down into detailed views of network activity helps to quickly pinpoint locations and causes. All the information is there."
"I really love the Data Explorer. I use it all the time to go in and craft exactly what I need to see. I'm able to then take that story and explain it to the executives. I've done that a couple of times and it is helpful."
"We're also using Kentik to ingest metrics. It's a useful feature, and its response time, whenever we're pulling back the data, is higher than our on-prem solution."
"The most important feature is cybersecurity."
"In terms of the solution’s real-time visibility across our network infrastructure, I have not been able to find any other monitoring or netflow visualization tool that gives me the kind of information I get from Kentik. If I need to take a deep-dive into something that I see, it's really easy for me to do that. Whereas with most other things, I have to use five or six other tools to get that kind of data, with Kentik, I have it all in one place."
"Having the API access allows us to do a great deal of automation around a lot of our reporting and management tools."
"The most valuable feature is being able to pull traffic patterns; to and from destinations. We're able to understand where our traffic is going, our top talkers from an AS set, as well as where our traffic's coming from."
"We're pretty happy with the API functionality. It's web, and it's very simple to set up queries. It has served us well and you don't need to be an expert on the API or the product to set these things up."
 

Cons

"The solution could be more user-friendly."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"It should be easier to collect the logs with companies like Sumo. However, based on my discussions with the salespeople, I understand that's how they make their money. With the enterprise product, they want people doing those kinds of enterprise features to do the logging. They want them to pay a lot of money, and that's where I have an issue with them. That should be a default. You should be able to get the log no matter what. The logging should be universal."
"The analytics, basically the dashboard, doesn't have much to it."
"There might be helpful if there was some web application firewall feature."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"Technical support is lacking."
"The product should provide improved bot detection and management."
"The solution's pricing could be better."
"What I don't like about Fastly is that they charge a heavy price."
"Fastly's customer service area needs improvement."
"Support is not that great."
"It is missing a "staging" platform to deploy a test configuration with all of the real settings, which would allow us to properly test before putting it into production."
"Stronger analytics would be helpful, like showing configurations that haven't served a certain amount of traffic in a while. With many properties, things can get lost track of - duplicates or unused configurations not properly decommissioned."
"I believe they're already working on this, but I would love for them to create better integrations from network flow data to application performance — tracing — so that we could overlay that data more readily. With more companies going hybrid, flow logs and flow data, whether it be VPC or on-prem, matched with application performance and trace data, is pretty important."
"There is room for improvement around the usability of the API. It's a hugely complex task to call it and you need a lot of backing to be able to do it. I should say, as someone who's not in networking, maybe it's easier for people who are in networking, but for me that one part is not very user-friendly."
"Sometimes, the tool has complications, so we must deal with the additional support from the tool's end."
"They're moving more in a direction where they are saying, "Hey, here's information that you may be interested in or may a need," before the question has to explicitly be asked. Continuing to move in that direction would be a good thing."
"In recent months, I've noticed that while the industry is trending towards AI, Kentik has room for improvement in this area."
"We asked for a way, regarding the potential networks that exist, to hook Kentik up with external tools like peering DBs to correlate things together and see what we can do... This is all in the [next] beta now."
"The only downside to Kentik, something that I don't like, is that it's great that it shows you where these anomalies lie, but it's not actionable. Kentik is valuable, don't get me wrong, but if it had an actionable piece to it..."
"I would like to see them explore the area of cost analysis."
 

Pricing and Cost Advice

"The solution is expensive when compared to other products but offers unlimited bandwidth."
"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 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."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The cost primarily depends on the size of the organization."
"The price of the solution is expensive."
"You need to pay a premium price for the tool."
"The pricing has been very competitive."
"In my opinion, Fastly is priced competitively."
"The solution is cheaper than other products in the market."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"Fastly is less expensive than one of its competitors."
"It is an expensive solution."
"The tool is cheaply priced."
"We have an annual contract with Kentik that we renew each year for a set number of licenses. We also have some burstable licenses which we can spin up and spin down, and those are paid as they are used."
