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

Quotes from Members

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

Pros

"The response time to an attack is instant. We've used some outsourced solutions in the past, out in the cloud, that weren't so quick. But it's all within our control now. We control how fast it mitigates."

"We were convinced that within a year, we'd definitely earn back the investment, both in the A10 equipment, as well as developing the end-to-end solution, including the integration with our administration systems."

"Availability is absolutely critical to our business; we get attacked two and three times a day at times, and although the attacks happen every day, they're not a big deal anymore because the mitigation takes care of it."

"The solution has reduced the amount of manual intervention required during an attack. We have the inline solution and when it comes to the customers that we have on it, it has saved us some troubleshooting time."

"I had a rather positive experience with A10 Networks Support Service."

"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."

"The most valuable feature of A10 Thunder TPS is load balancing."

"The solution is easy to use and implement in terms of operations."

More A10 Thunder TPS pros

"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."

"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."

"This is a hybrid solution."

"I like the fact that the product provides a hybrid solution."

"The most important aspect, in general, is that the price is suitable for most clients."

"The DDoS protection features are valuable."

"It is a good solution, its vendor support is the most valuable, and it is simple and works well if you have Juniper MX routers."

"It is a very efficient and robust appliance."

More Corero pros

Cons

"It is very difficult to implement. It should be made a bit easier to implement. There is also a lack of resources on the internet. They need to develop more resources."

"The solution is a little expensive."

"We currently do not use the solution's machine-learning-powered Zero-day Automated Protection because of an issue with it."

"The solution needs improvement in terms of fail-open."

"The last issue we had to contact them about was just a question of a false-positive. The A10 system wasn't supposed to decide what is a false-positive. So if we send it good traffic, it's supposed to just pass that good traffic through. But we opened this last ticket because the A10 did block some of the good traffic. Their support had to tweak it a little bit, but it wasn't anything that took a long time."

"Its documentation could be better."

"The upgrade process for the boxes is not efficient. We have to go through the A10 aGalaxy where we have issues, like timeouts. They told me it was fixed in the latest version, but I tried to do it on the Portal and it is not working all the time."

"I rate Thunder TPS seven out of 10 for scalability."

More A10 Thunder TPS cons

"The product must provide more Layer 7 capabilities."

"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."

"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."

"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."

"Lacks international presence."

"I'd like to see an increase in Corero's international team. Our clients are generally companies with an international presence and Corero is not represented in all the countries where our clients have presence."

"It could use support in Spanish."

"Juniper is known in our country, but it is not very popular."

Pricing and Cost Advice

"Pricing is very reasonable."

"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 tool is expensive. If one is low price and ten is expensive, I rate the tool's price as a ten."

"We did a price survey, and compared to other solutions, A10 Thunder TPS wasn't cheap."

"Pricing was much higher with Arbor (APS) for the same type of solution."

"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."

"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 price of Corero is affordable."

"Its price is normal."
