Effectively defends against threats like cross-site scripting (XSS), SQL injection, and others

It does bring value. For example, consider a BFSI customer. Their application is critical and represents their brand. Without a WAF, an attack could take their application down, harming their reputation. It leads to hampering the customer's workflow. With an Imperva WAF, they protect against attacks like DDoS or SQL injection, ensuring their application remains available and customers are happy. That's the main benefit for both the customer and the organization. The impact depends on the customer's use case. If their business primarily operates online, a CDN is beneficial for traffic optimization. Moreover, the integration options depend on the specific use case of our customers. Generally, integration capabilities are good with SIEM (Security Information and Event Management) parts.

The integrated application protection has helped secure our critical web applications

Valuable features of Radware Alteon include global server load balancing, SSL offloading, Layer 7 load balancing, automation and traffic scaling, real-time analytics, and reporting. Alteon's integrated application protection has helped us. As a state government agency, we face increasing threats and need to secure our critical web applications. Our finance websites are the primary targets for DDoS, SQL injections, and other sophisticated attacks. Traditional security is insufficient to defend against the volume and complexity of the attacks. We need protection against attacks on the application and infrastructure layers and DDoS attacks. Alteon offers visibility and actionable insights into each security event. Radware has free training available on their website. I've completed a few training courses and found them very helpful for me in my daily work. The basic course covering the UI takes a week, and it was easy to understand. When we're troubleshooting a scenario, we can check the Alteon knowledge base articles. The combination of training and the knowledge base shortens the learning curve.

Quotes from Members

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

Pros

"The tool's profiling feature maps all the web application directories and related components on the profile directory. It has improved the security of my client's website applications."

"Imperva Web Application Firewall is a highly stable solution and is very mature."

"The solution can be configured in just a couple of minutes."

"The solution can scale."

"One good thing about Imperva Web Application Firewall is it can be on the cloud and also it can be on-premise."

"Learning mode and custom policies are helpful features."

"Very scalable and very stable firewall for web applications, with a good interface in its cloud version. Mitigation is its most valuable feature. The technical support for this product is also good."

"It mitigates all of the availabilities of risks around web applications."

More Imperva Web Application Firewall pros

"his solution allows me to secure applications, by blocking suspicious traffic based on the signature that has been enabled for that particular application."

"Security is one of the most valuable features that I like. It is easy to use and easy to configure."

"The link load balancing is a great feature."

"The round-robin distribution of the load is quite useful."

"Alteon helps us troubleshoot issues. It provides us statistics on application, server, and load balancer response that we can use to identify problems or latency."

"The UI is user-friendly."

"With Alteon, the load-balancing options are practically unlimited. We haven't had any issues with offloading, decryption, putting in cookies, or any other load-balancing features. We can check URLs, etc., on the back end for load balancing instead of running a TCP check. We're also doing some certificate stuff on there. Alteon covers all of the standard load-balancing techniques, and we employ most of them daily."

"SSL offloading feature is one of the most important features. Traffic distribution is also done very well by Radware."

More Radware Alteon pros

Cons

"The signature updates could be faster. Sometimes we have to upload signatures to the Imperva portal for checking and analysis before we can use them."

"They recently separated the WAF and the DAM management gateways in order for each of these to be managed from different areas, so I believe it now requires additional investments for what was previously a single complete solution."

"Imperva Web Application Firewall is very expensive."

"It would be nice to have more security control over mobile applications so I would suggest adding more mobile security features. It would also be beneficial to see improvements in regards to interface bandwidth performance, CPU time, and RAM size. Learning capability of the device is quite weak."

"I would like to improve the tool's turnaround time in terms of support."

"The tool's UI is complicated. It would be best to have a more accessible UI dashboard to make the job easier."

"The product's customization capabilities are a bit problematic, requiring support cases for backend modifications."

"The only disadvantage of Imperva is that it is a pretty costly solution."

More Imperva Web Application Firewall cons

"I would like to see the loading documentation improved."

"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."

"They keep integrating new features that sometimes break our production, but we use clustered systems, so we can test those software releases."

"The solution lacks HA configuration."

"The solution could be more robust."

"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."

"There are certain features I would like to see in the next release."

"Recently our team was talking about the things you can customize in Alteon and the level of programming that doing so demands. I would like to see more information on how to customize the programming and troubleshoot."

More Radware Alteon cons

Pricing and Cost Advice

"The solution's pricing is an issue."

"There are some licenses that you have to buy to use some features. Its price could be better. Price is always important because, at the end of the day, customers have a budget. If you can meet the budget, you can sell, and if you don't, you cannot sell."

"Imperva’s pricing is a bit higher in the market since it offers a full-blown WAF."

"Everybody complains about the price of this solution."

"We sell three-year licenses for Imperva Web Application Firewall to our customers. The price is a little expensive."

"Make sure you understand the way that Imperva charges. It's very affordable. However, I would like to see a package with the Virtual Patching included. You get to do patching separately."

"It is very costly, but the return on investment is very high. Its cost was around $70,000, and we got it back in just six months."

"The cost of this solution depends on the platform."

More Imperva Web Application Firewall pricing and cost advice

"The Radware team we work with always gives us the best price. As a university, our budget is limited. We need something that is the best solution but with a low or economical pricing. We are getting a better price than competitors. The shift from Barracuda to Alteon was primarily due to cost efficiency. It is very economical, and the price fits our business needs."

"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 pricing seems reasonable to me for what the solution provides. It is within the parameters of this type of solution."

"The price conforms to what the tool provides. It is not an inexpensive tool and not all companies can afford an ADC solution such as Alteon. However, it justifies its price with the options it offers."

"Radware Alteon is less expensive than many of the other competitors."

"The cost of Radware Alteon is mid-ranged."

"It is the best in the industry. It was better than the competition, and that is what made us go ahead with them."

"I'm content with Alteon's pricing."

Questions from the Community

Which is the best DDoS protection solution for a big ISP for monitoring and mitigating?

My recommendation is Imperva.

Is Citrix ADC (formerly Netscaler) the best ADC to use and if not why?

For ADC, any ADC can do a good job. But in case if you want to add WAF functionality to the same ADC hardware you have to look for other ADC's like F5, Imperva, Radware, Fortinet, etc.

DDoS solutions: Any other solutions to consider aside from Radware DDoS Protection Service and F5 Silverline DDoS Protection?

You can have a look to Imperva Cloud WAF, the anti-DDoS mitigation is under 1s and works very well. I observed a lot of DDoS attacks that were well managed (even not seen by the customer) by Imperv...

What do you like most about Radware Alteon?

It saves us a lot of work in terms of management since it has tasks already defined automatically. That enables us to better administer our services. It is very dynamic and easy to administer.

What is your experience regarding pricing and costs for Radware Alteon?

We have a three-year contract with Radware. It is beneficial to have a longer-term contract because you can obtain more discounts. It seems to be a much cheaper alternative. We use their Gel Elasti...

What needs improvement with Radware Alteon?

It is a fairly complete service and it is difficult for me to think of what can be improved. A feature that I would like to see included in the next version might be better analysis when working wi...

We can also make changes to services that are already running, as I mentioned before, the graphical interface is very intuitive and you can almost always make the most common changes quickly. Radware has been characterized by being extremely robust. This gives us the confidence to offer our users a continuous service.”

A director of consulting says, “The most valuable features are the load-balancing and reverse proxy. Global-load balancing as well is valuable. I also find it to be stable. To date, we have not had any issues with it.”
