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.
Saurav Kumar - PeerSpot reviewer
Offers protection to users from external threats
NGINX App Protect secures our company's application, and it has helped me a lot, considering that we have critical infrastructure in India where we see how lots of attacks come onto our organization's servers. The tool offers protection against multiple threats present in India's IT ecosystem. The tool helps our company to make our payments secure, meaning it has the ability to provide a secure payment environment in India. Speaking about the improvements in our company's application performance since implementing NGINX App Protect, the gRPC support for the solution is very low. My company is not getting any proper documentation on how to deploy gRPC over NGINX App Protect. I recommend the product to those who plan to use it. People can use the product as their company's base server, WAF, or for its proxy manager, depending on the business requirements. My company follows PCI DSS compliance because we operate in a payment-related industry. Right now, my company follows all the standards, so we comply with all the requirements and policies. I rate the tool an eight out of ten.

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

"From what I've seen so far, there are no negatives to report as of yet"
"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."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"I rate its stability a ten out of ten."
"The most valuable feature is its usability."
"It is a fast and secure DNS."
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"The solution provides good load balancing and protection against DDoS attacks."
"WAF is useful to track mitigation, inclusion, prevention, and the parametric firewall."
"It's very easy to deploy."
"We were looking for a product that is capable of complete automation and a container based solution. It's working."
"The most valuable feature of NGINX App Protect is its open source."
"The stability of the product is very impressive since it handles 60,000 to 70,000 requests or transactions per second."
"The most valuable feature of NGINX App Protect is its flexibility."
"The tool's most valuable feature is the OWASP certification. Additionally, the tool's ability to enforce strong passwords and OTP within minutes is impressive. With its analytics and recommendations, it is a very good solution."
"NGINX App Protect's best features are auto-learning, which creates a profile of applications that are deployed, bot protection, and force protection, which lets you configure your brute force policy and alert for and prevent brute force attacks."
"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."
"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."
 

Cons

"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."
"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"Latencies are always a problem."
"We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."
"Integration involving API with other products could be more user-friendly."
"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."
"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."
"DNS Management."
"It doesn't have more advanced features like no false-positive security, which you can configure in Advanced WAF."
"The product's user interface is an area with shortcomings as it can be quite confusing for users, making it an area where improvements are required."
"It's challenging if you need to go for a high throughput."
"Setting policies and parameters through the UI should be more automated because the process is manual, where we can only edit one rule at a time."
"The configuration needs to be more flexible because it is difficult to do things that are outside of the ordinary."
"The product's price is high, making it an area of concern where improvements are required. The tool's licensing model is also not good."
"The dashboard could provide a more comprehensive view of the status of the connections."
"It would be better if it were easier to implement and if there was more information from F5 regarding hardware requirements and specifications to deploy the service, to avoid disruptions after implementation."
"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."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
 

Pricing and Cost Advice

"The tool is a premium product, so it is very expensive."
"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 solution is expensive when compared to other products but offers unlimited bandwidth."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"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."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"The price of the solution is expensive."
"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."
"The licensing fees for this solution are pretty expensive for what it does, but there is no alternative."
"The price of NGINX App Protect is approximately $3,000 annually. All of our licenses are observed by a managed service partner."
"NGINX is not expensive."
"NGINX App Protect is expensive."
"There are no additional fees."
"Our licensing costs are about $40,000 a year."
"The price of NGINX App Protect is not much different from the products that fall under the leader category of Gartner Magic Quadrant."
"Really understand the licensing model, because we underestimated that."
"Signal Sciences is pretty cheap compared to other solutions."
"The pricing is 50% less than Akamai."
"The product has an affordable cost."
