Management console adds value and technical support delivers timely solutions
I had issues with the user interface because, when putting settings up, the system asked me for strange things like virtual local networks that I didn't create. For example, I set an NTP server, and after some clicks, a message appeared stating 'setup is incorrect'. It asked for a VLAN even though no VLANs were created. We had to find workarounds for issues like A10 blocking necessary traffic, sometimes leading to decreased security, because it was the simplest way to deal with them. This was a real issue. A more flexible policy for demo licenses would also be helpful.

Effective network and DDoS protection with suitable pricing
I use Corero for network DDoS protection projects. It is particularly effective in providing protection against network DDoS attacks I find Corero to be good, especially in a wide area. It does not have application filtering or application DDoS prevention, but for network DDoS projects, it is…

Quotes from Members

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

Pros

"The GUI is very use-friendly. You can configure it through CLI or GUI, they give you an option to choose. It's a good solution in terms of the appliance itself. It's very light compared to other brands that offer DDoS solutions."
"Based on previous equipment that we had, it's amazing that this device can do what it can do in a 1U form factor. The devices that we have right now have never gone over capacity and we've actually mitigated some pretty large attacks."
"The solution's support is one of the coolest things about the product. I"
"We can keep track of all the customer's requirements. We can forecast our trails and we can forecast our overall financial things."
"The primary benefit that we see from their systems is that their filtering technology has the ability to detect and drop the malicious traffic from the legitimate traffic with a high success rate. That, in combination with the very small effort needed to manage their systems, are the two most important benefits to us."
"They give us the ability to configure many features for DDoS. There are many items that we can use."
"Thunder TPS has automated mitigation and fully managed support in case the device cannot handle the attack. They have engineers available to respond."
"It is a scalable solution."
"The DDoS protection features are valuable."
"The most valuable feature of Corero is its ability to handle smaller attacks in terms of the amount of volume and time. You can handle almost 100 perfect of the attacks locally."
"The most important aspect, in general, is that the price is suitable for most clients."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"This is a hybrid solution."
"It is an agnostic and transparent inline platform, which means that the maximum visibility of the symmetric and asymmetric traffic is available, even allowing bidirectional detection of the attack."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
 

Cons

"I had issues with the user interface because, when putting settings up, the system asked me for strange things like virtual local networks that I didn't create."
"Its documentation could be better."
"If there's one aspect of A10 that needs improvement it would be the training. All of their training is done online, at least in what we've been exposed to. I would like to have a classroom environment for training... It would give [people] a chance to provision it."
"The problem here is when you buy another box from A10, they want to put Thunder TPS to run, and it works okay, after which we cannot block it for another solution to be used, which is a problem for me where improvements are needed."
"The solution needs improvement in terms of fail-open."
"We currently do not use the solution's machine-learning-powered Zero-day Automated Protection because of an issue with it... We also use the aGalaxy platform, which is a management platform for the TPS devices. The issue is that some TPS features were added at the TPS level but weren't carried over to aGalaxy, and we manage all of our devices through aGalaxy. So we can't actually use some of the new features that are available on the TPS because that functionality doesn't exist in aGalaxy. That is one of my biggest complaints."
"The solution is a little expensive."
"I would like for them to develop an advanced reporting feature."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"The product must provide more Layer 7 capabilities."
"The approach taken by Corero is to partner with other organizations in order to address volumetric attacks that cannot be handled by the hardware installed in the infrastructure. Corero does not have a solution for these attacks, so they are looking for partners to help them manage them. This approach is supplemented by local hardware, but the main focus is on the partnerships. It would be beneficial to have a more complete solution."
"Lacks international presence."
"Juniper is known in our country, but it is not very popular. There is also not enough information about Corero. Our enterprise and financial sectors don't know about this solution. They need to provide more information and do more marketing for this solution in our country."
"It could use support in Spanish."
 

Pricing and Cost Advice

"We had a customer who was down for six hours and the loss of revenue for him was three times the price he was paying for us per year. The customer just said, "I don't care about paying you because on only one attack I saved money. It's three times better than losing money.""
"The tool is expensive. If one is low price and ten is expensive, I rate the tool's price as a ten."
"Pricing is very reasonable."
"We did a price survey, and compared to other solutions, A10 Thunder TPS wasn't cheap."
"We may need to pay fifty percent more if we purchase other solutions. For the payments made to A10 Thunder TPS, we have received three-year support."
"The financials are always a challenge with this type of technology. That's not really a product-functionality thing but it's the area where we push A10 the most."
"Pricing was much higher with Arbor (APS) for the same type of solution."
"Its price is normal."
"The price of Corero is affordable."
