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.
Abdalla Kenawy - PeerSpot reviewer
Provides great insights about requests, helping secure our infrastructure
I am working on AWS Web Services to manage infrastructure as a platform. I use services like KMS, EBS, CloudFront, S3, and EC2. I also work on WAF version two AWS WAF has provided great insights about requests, helping secure our infrastructure. It contributes by continuing to get the latest…
Shashank N - PeerSpot reviewer
Provides good stability, but the agent-based approach could be more convenient
The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF. Additionally, the agent-based approach presents challenges with managing agents across versions and dependencies on specific application platforms like Apache or NGINX, leading to compatibility issues and complexity in integration. This agent-based system proved particularly difficult to manage.

Quotes from Members

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

Pros

"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"What I like best about Cloudflare is that my company can use it to trace and manage applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare also sends you a link to check your equipment and deployment and track it through peering, so it's a valuable tool."
"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."
"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"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."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"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."
"AWS WAF is something that someone from a cloud background or cloud security background leverages. If they want to natively use a solution in the cloud, AWS WAF comes in handy. It's very useful for that, and the way we can fine-tune the WAF rules is also nice."
"AWS WAF is a stable solution. The performance of the solution is very good."
"The most valuable feature is the addition of managed tools that help us create customizable rules. In case we want to block a particular request, we can make use of those rules."
"We do not have to maintain the solution."
"The product’s availability, ease of configuration, and documentation are valuable."
"The customizable features are good."
"We can host any DB or application on the solution."
"They filter a lot of attacks out."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
"Fastly (Signal Sciences) integrates and tags the intermittent traffic based on patterns. It generates signals and provides them in a dashboard where we can view them and decide whether to allow or deny traffic. It's a more advanced and easy-to-navigate dashboard."
"Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate."
"The product's most valuable feature is its ability to set up the rules easily."
 

Cons

"The documentation could improve for Cloudflare DNS."
"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."
"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."
"Support response time could be improved."
"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."
"Latencies are always a problem."
"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."
"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."
"This solution could be improved if the configuration steps were more specific to WAF, compared to other cloud services."
"For now, there is no feature to protect against attack of the bad bots"
"It's a bit difficult to apply the right rules for the right security."
"AWS WAF's signature sets have room for improvement due to false positives."
"I would like to see it more tightly integrated with other AWS services."
"We should be able to do proper whitelisting."
"The solution could be more reliable."
"The technical support does not respond to bugs in the coding of the product."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
"The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF."
"The UI is not very intuitive and could be better."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
 

Pricing and Cost Advice

"The solution is expensive when compared to other products but offers unlimited bandwidth."
"The price is reasonable."
"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."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"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."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."
"We don't have any issues with the price."
"It's cheap."
"For Kubernetes microservices, AWS is more expensive compared to OCI. AWS costs approximately 70 cents per hour, while OCI is 50% cheaper."
"AWS WAF has reasonable pricing."
"We are kind of doing a POC comparison to see what works best. Pricing-wise, AWS is one of the most attractive ones. It is fairly cheap, and we like the pricing part. We're trying to see what makes more sense operation-wise, license-wise, and pricing-wise."
"For our infrastructure, we probably pay around $16,000 per month for AWS WAF. Because alternative WAF solutions provide even more features, I think the AWS WAF is a bit pricey"
"The pricing is good and manageable."
"It has a variable pricing scheme."
"The price of AWS WAF is expensive if you do not know how to manage your software up or down. I price of the solution is average amongst the other competitors but it would be better if it was less expensive."
"The pricing is 50% less than Akamai."
"Signal Sciences is pretty cheap compared to other solutions."
"The product has an affordable cost."
