Useful for protecting and supporting users against attacks
One problem for me with A10 Thunder TPS is that the box comes from another country in Brazil. In the tool, there is no one key to block it. For example, in F5 Networks, we have a key. If you try to buy another box from Huawei or from F5 and try to enable them in A10 Thunder TPS, you need a key to do 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.

A solution requiring straightforward maintenance while remaining cost-effective compared to its competitors in the market
I am not in a position to speak about the areas where the solution needed improvement because I resigned during the implementation phase. At that time, the implementation was ongoing, and everything seemed to be going well. Using the solution, our team managed to transfer a couple of routers through a few areas. However, I believe the migration is still ongoing. Nonetheless, the first phase of the implementation was successful before my departure. There was a certain level of performance degradation in the solution, which I don't know if it can be tuned. This is because I was working for a short period on the solution. In my experience, it is an area that can be improved while also considering the stability and scalability aspects of the solution. If one wants to scale up, then one needs to change their plan. However, the thing is, one can always go for the larger scale based on one's anticipation of future traffic.

Quotes from Members

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

Pros

"I had a rather positive experience with A10 Networks Support Service."
"We selected the solution because of its programmable automated defense using RESTful API. We didn't want to connect to the box. We wanted to be able to do some automation. We wanted to have our own portal because we wanted to connect our customers to our own UI using the A10 API. It has been good and exactly what we need."
"The solution is easy to use and implement in terms of operations."
"The solution's support is one of the coolest things about the product. I"
"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."
"The product's initial setup phase is very simple."
"They give us the ability to configure many features for DDoS. There are many items that we can use."
"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."
"Based on the support received for implementation, I rate the solution's technical support a nine out of ten."
"Filters can be customized depending on the characteristics of the attack traffic. This feature has made it easier for Nexusguard's SOC team to further isolate any specific attack that can't be blocked by pre-configured mitigation."
"The support team was helpful."
"The managed service allows us to confidently rely on Nexusguard’s professional team to take relevant actions as and when required to make sure DDoS attacks are successfully mitigated, ensuring 100% uptime of our service."
"Cloud Diversion is another good feature packaged with the whole solution. When attack traffic is detected, Cloud Diversion triggers to automatically route our prefix to Nexusguard’s scrubbing center, ensuring that all attack traffic is dropped in the shortest time possible."
 

Cons

"They have a cloud scrubbing feature that redirects the traffic if the on-prem appliance can't accommodate a large amount of traffic but it's not available where we are."
"The solution needs improvement in terms of fail-open."
"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."
"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 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."
"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."
"The solution is a little expensive."
"The solution must provide features for the post-processing of the traffic type and the traffic quality."
"The mitigation scope of Origin Protection is not fully efficient as there could be delays in activating the countermeasures."
"There was a certain level of performance degradation in the solution, which I don't know if it can be tuned...In my experience, it is an area that can be improved while also considering the stability and scalability aspects of the solution."
"One thing that we would like to improve from them is to provide more training to SOC team for them to have a deep understanding of the solution so that they would always be ready to answer anything without the need to escalate queries to senior personnel."
"One of the features that should be added to the next release is report generation. Currently, reports can be downloaded every month and are only available at the beginning of each month. It would be nice to generate the reports based on specific dates that we prefer and not have to wait until the next month for the current month’s report."
 

Pricing and Cost Advice

"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."
"Pricing is very reasonable."
"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."
"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."
"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.""
"On a scale of one to ten, where one represents a cheap option, and ten represents an expensive option, I would rate the solution a seven in terms of cost."
