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

"Thunder TPS has automated mitigation and fully managed support in case the device cannot handle the attack. They have engineers available to respond."
"I had a rather positive experience with A10 Networks Support Service."
"It is a scalable solution."
"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 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 solution has been rock solid for us; we haven't had any issues, we've had numerous attacks, and it's worked perfectly."
"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."
"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."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us, and this is important."
"The product's initial setup phase was really easy."
"We have researched them all, and it's a good solution all around."
"The protection resources and the support are valuable features of the solution."
"Compared to other DDoS mitigation solutions with similar deployment, FortiDDoS does not require a 24x7 NOC and has lower TCO."
"The solution is very user-friendly and very easy to use."
"Among its key features: Detects and mitigates DDoS attacks at L3 to L7; negligible to zero false-positives; Generates and sends reports without the need for an expensive third-party solution."
"The product allows the users to adjust the thresholds."
 

Cons

"The solution is a little expensive."
"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."
"Its documentation could be better."
"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."
"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."
"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."
"We currently do not use the solution's machine-learning-powered Zero-day Automated Protection because of an issue with it."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"I would like to see analytics, big data."
"All those thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"Alerts and reporting features must be improved."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"The solution can be a little more user-friendly and it can be more affordable."
 

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 was much higher with Arbor (APS) for the same type of solution."
"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.""
"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 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 did a price survey, and compared to other solutions, A10 Thunder TPS wasn't cheap."
"The product’s pricing needs improvement."
"It's quite pricey."
"The solution is reasonably priced."
