Project Manager at a tech vendor with 1-10 employees
Manages SSL load balancing and offload efficiently while providing excellent support
The most valuable feature is the support from the engineering team. They quickly resolved a VLAN issue that other vendors could not. The product allows us to manage multiple networks and VLANs into a single box and add numerous web services and farms efficiently. The SSL management and integration capabilities are also standout features.

Room for improvement with user interface while competitive pricing impresses
It is managed through Infrastructure as Code, so all configurations can be managed in the code itself, which is beneficial. Because it uses rules, it is easy to set up, and we have many different sites where the configurations are straightforward. Though the UI is not very interactive, which is a downside, we can manage many things. The UI is not very intuitive and could be better. However, we manage all the configurations through code, which is easy to maintain. It has extensive anomaly detection capabilities, so the traffic is classified into several categories where thresholds can be defined and customized based on false positives and false negatives. This is advantageous because you do not need to tweak it very often. Once you set it up, an audit once a quarter would suffice. 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.

Quotes from Members

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

Pros

"I like the web GUI. It's very intuitive and easy to use."
"The features that mitigate attacks are very valuable."
"I like the concept of self-service, that I can do everything on my own."
"The integrated application protection provided by Alteon is very good. It really helps to avoid false positives in some cases. It provides important granularity to avoid a situation in which security or cybersecurity scenarios escape us."
"A user-friendly and reasonably priced solution."
"The interface is easy, it's friendly, and has good alerting."
"I find the best features to be the flexibility and ease of use. The configuration is very straightforward."
"The GUI was a valuable feature. It was uncomplicated and easy to use."
"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."
"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."
 

Cons

"It can be improved by combining the web application firewall (WAF) facility."
"I would like the solution to display and help visualize the reference map more easily. I would also like to better understand where queries come from and know which users are consulting the application, along with which app."
"There is room for improvement in reducing the number of false positives I receive. We could benefit from more configuration options to avoid these false positives, which can be overwhelming for a security analyst."
"They keep integrating new features that sometimes break our production, but we use clustered systems, so we can test those software releases."
"The service could be improved by better customer support."
"Alteon's user interface and usability can be improved by providing a more modern and streamlined design and focusing on simplifying workflows in the UI."
"We don't integrate anything with it because most things don't integrate with Radware. If it were F5, we could integrate it. We can integrate F5 with practically anything that integrates with a load balancer, but that's not the case with Alteon."
"The solution lacks HA configuration."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
"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."
 

Pricing and Cost Advice

"The cost of Radware Alteon is mid-ranged."
"The pricing seems reasonable to me for what the solution provides. It is within the parameters of this type of solution."
"Radware LinkProof is neither cheap nor expensive."
"It has a good price point and is more reasonable than other comparable products"
"I'm content with Alteon's pricing."
"Price-wise, the solution is a reasonable one."
"Alteon's price is excellent compared to other solutions. F5 costs around twice as much. We still have about three years left before this hardware reaches the end of its life. We're migrating to the cloud, and phasing some of this out, but it's nice that they've given us a long window to keep their hardware in place."
"It is cost-efficient. That is why we have gone with Alteon. As a product, it is efficient and robust. We have not faced any issues with the device."
"The product has an affordable cost."
"The pricing is 50% less than Akamai."
"Signal Sciences is pretty cheap compared to other solutions."
