Load balancing has simplified deployments and improves application performance monitoring
I don't think of features that will make Radware Alteon better because it is already better, but to be able to compete also with other competitors, the price is something to consider. It is not actually that expensive, but for their level, there are other load balancers with the same feature, but they have a lower price, so pricing is the only point I can give. In the future, I would like to see some other security features added, such as DDoS, which is Distributed Denial of Service. Currently, it has the Web Application Firewall feature, but in the future, they can also add a DDoS feature or a more in-depth DDoS feature.

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

"It is easy to expand. Our clients are enterprise-size."
"The UI is user-friendly."
"The product offers high availability."
"The command line interface is simple and very user-friendly."
"I like the ADC feature and the global certificate feature."
"Not only was Radware Alteon less expensive but it is more user-friendly in the interface and configuration."
"The GUI was a valuable feature. It was uncomplicated and easy to use."
"I like the web GUI. It's very intuitive and easy to use."
"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."
"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."
"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

"It is not actually that expensive, but for their level, there are other load balancers with the same feature, but they have a lower price, so pricing is the only point I can give."
"The user interface can be improved."
"The solution lacks HA configuration."
"Performance could be improved."
"We recently had a problem with the tables Obsolete ARP which was observed by the support team. It would be good to diagnose and solve this problem with a patch since it is not documented that it will be solved in later updates."
"When we approached customer service and support with configuration-related issues and multiple cases of bugs in the Radware Alteon software, the response was slow, and there was no resolution."
"Radware should work on the vulnerabilities part. There are third-party security solutions that do the security vulnerability assessment (VA). The assessment part needs to be worked on and improved. There should be more solutions. If any issue comes up and if any vulnerability is reported, the Radware team should do an R&D on that and work on that. They should give the solution to the customer."
"We are in the process of updating our version of the solution, so judging what should be improved is difficult. But in some cases, the visualization takes a while, especially for mapping issues."
"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."
"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."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
 

Pricing and Cost Advice

"It is not the priciest and it is not the cheapest. For our solution, it was right in the middle of price performance."
"It is the best in the industry. It was better than the competition, and that is what made us go ahead with them."
"Our government agency opted for Radware Alteon due to its affordability and efficiency. While I can't say precisely how much it costs the organization, the price per device. In India, we always look for affordable products, so I assume Alteon is cost-effective because the government chose it."
"The pricing is better than the competition. It is getting more pricey as the years go on, as more people are migrating to it, and as the technology gets better."
"Its pricing is very good. It is very competitive. Radware Alteon is the leader in the market. At a lesser price, we get a good product and also good support. Other vendors who are providing load balancers charge separately for two items. You have the hardware cost, and you have the support cost, whereas, in the case of Radware, you get both in a single package."
"Price-wise, the solution is a reasonable one."
"Radware Alteon is less expensive than many of the other competitors."
"Radware LinkProof is neither cheap nor expensive."
"The pricing is 50% less than Akamai."
"Signal Sciences is pretty cheap compared to other solutions."
"The product has an affordable cost."
