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.
Bonieber  Orofeo - PeerSpot reviewer
Application gateway optimizes performance and simplifies cloud transitions
There are a lot of things I appreciate about Microsoft Azure Application Gateway. Microsoft Azure Application Gateway is beneficial for us as it helps in publishing our website, providing us comfort when it comes to the availability of our applications. The autoscaling feature in Microsoft Azure Application Gateway is very obvious, and I have no issues with it; it is well planned and organized. Microsoft Azure Application Gateway impacts our cost savings while maintaining higher performance. The Web Application Firewall (WAF) in Microsoft Azure Application Gateway has been very effective in protecting applications from security threats. Microsoft Azure Application Gateway helps us manage our AI-driven applications by enabling faster transactions, improving our work.
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

"The solution offers the flexibility to control configuration rules."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"It's a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."
"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."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"The most valuable feature is its usability."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"The solution is very good at mitigating threats."
"Application Gateway automatically redirects unwanted users and takes care of the security aspect. It also handles the performance side of things, which is why we use it."
"Using policies to link and manage these URL-based routing configurations is also valuable."
"The security feature in all the layers of the application is the most valuable."
"This is a SaaS product, so it is always up to date."
"The solution is easy to set up."
"I rate Microsoft Azure Application Gateway's scalability a ten out of ten. My company has more than 1000 users who use it daily."
"Microsoft Azure Application Gateway is an easy-to-use solution."
"The production is a valuable feature."
"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."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
"The product's most valuable feature is its ability to set up the rules easily."
"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."
 

Cons

"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."
"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."
"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."
"It should confirm audit findings of the assigned area with auditees to ensure that the audit conclusions are based on an accurate understanding of the issues."
"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"The pricing could be improved."
"There might be helpful if there was some web application firewall feature."
"It could be more stable, and support could be better. It would also be better if they offered more features. For example, it lacks security features. Before we used another English solution, and we realized that some of the rules were not set up correctly and passed through the Application Gateway's English controllers. But the problem, in this case, is if you send ten rules, for example, six rules hit some issues. IP address blocking could be better. The rules, for example, don't work properly. If you have one issue, one rule or another rule will not work. This sounds like total madness to me."
"I want the solution's support to improve. The tool is also expensive."
"Scalability can be an issue."
"The security of the product could be adjusted."
"The tool is a pain to deal with when it comes to the area of configuration."
"The pricing of the solution could be improved. Right now, it's a bit expensive."
"It does not have the flexibility for using public IPs in version 2."
"We faced some downtime while validating CNAME."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
"The UI is not very intuitive and could be better."
"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."
 

Pricing and Cost Advice

"The price of the solution is expensive."
"That is one of the great features. I was able to access the majority of the features and services for free."
"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"We are using the free tier of the solution."
"The cost primarily depends on the size of the organization."
"I rate the pricing seven out of ten because some third-party solutions are even costlier than this."
"The solution is cheaper than Imperva. I rate it four to five out of ten."
"The cost is not an issue."
"We use the tool's basic subscription. Its licensing costs are monthly."
"Every solution comes with a license and cost. Microsoft provides the license and the total cost is for the maintenance every year."
"The product is expensive. I rate the pricing a seven out of ten."
"The price of the solution can be reduced a bit."
"The tool's pricing model is pay-as-you-go."
"Signal Sciences is pretty cheap compared to other solutions."
"The product has an affordable cost."
"The pricing is 50% less than Akamai."
