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.

Reliable protection and smooth setup enhance company security
Currently, I have two firewalls, with one located in Sorocaba, model 90D, and the other in São Paulo, model 30D. They are connected by VPN. I use the firewalls for VPN and final protection for my company, and my equipment is maintained by an internet company called Multiprox The equipment works…

Quotes from Members

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

Pros

"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."
"The solution's support is one of the coolest things about the product. I"
"Due to the availability and power of these devices, we've been able to ramp off our upstream cloud-scrubbing provider and handle all attacks on our own."
"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."
"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."
"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."
"They give us the ability to configure many features for DDoS. There are many items that we can use."
"We use it to protect our users and their data."
"The product's initial setup phase was really easy."
"Compared to other DDoS mitigation solutions with similar deployment, FortiDDoS does not require a 24x7 NOC and has lower TCO."
"I find this product the best on-premises (in-line) DDoS mitigation solution that suits my current and future requirements."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"The solution is very user-friendly and very easy to use."
"Packet inspection has been effective for mitigating DDoS attacks."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us, and this is important."
 

Cons

"We currently do not use the solution's machine-learning-powered Zero-day Automated Protection because of an issue with 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."
"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."
"We have had some issues with implementation. So, it is the only area that needs improvement."
"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."
"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."
"I would like for them to develop an advanced reporting feature."
"If there's one aspect of A10 that needs improvement it would be the training."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"Earlier versions of firmware had bugs that limit my options."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"All those thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"The product’s pricing needs improvement."
"The initial setup is complex. It is always complex."
"The web interface could be much better."
 

Pricing and Cost Advice

"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 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.""
"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."
"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."
"It's quite pricey."
"The product’s pricing needs improvement."
"The solution is reasonably priced."
