Executive SummaryUpdated on Dec 5, 2024

A10 Thunder TPS and Nexusguard DDoS Protection are competing products in the DDoS mitigation category. While A10 Thunder TPS excels in ease of deployment and customer support, Nexusguard is favored for its advanced features, appealing to those in need of a comprehensive solution despite potential higher costs.

Features: A10 Thunder TPS integrates robustly with existing systems and provides advanced threat intelligence, focusing on high-capacity traffic management with rapid attack mitigation. In contrast, Nexusguard leverages a global threat detection network and emphasizes ease of scalability with cloud-based protection, ensuring seamless and flexible solutions. Nexusguard's adaptable cloud infrastructure distinguishes it from A10’s hardware-based offerings.

Room for Improvement: A10 Thunder TPS could enhance its cloud capabilities for users preferring non-hardware solutions. More intuitive user interfaces and automation features can streamline its deployment process. Additionally, expanding integration with third-party tools might enhance its flexibility. Nexusguard could work on reducing initial setup costs and improving transparency around service performance metrics. Enhancing customizability for diverse threat environments and increasing on-premise options might attract a broader user base.

Ease of Deployment and Customer Service: Nexusguard offers straightforward cloud-based deployment, which allows for rapid implementation and easy scalability, backed by strong customer service. A10 Thunder TPS, though comprehensive, often involves intricate on-premise installations that require more technical management. However, A10 is recognized for its responsive customer support and technical expertise.

Pricing and ROI: A10 Thunder TPS provides a competitive pricing model with significant long-term ROI due to its hardware investment and lower ongoing costs. Nexusguard, with potentially higher initial expenses for its cloud-based solutions, offers long-term ROI rooted in service flexibility and reduced need for hardware updates. This creates a notable difference where A10 is more cost-effective for organizations leaning towards hardware investments, whereas Nexusguard's upfront cost is counterbalanced by its scalable and adaptable service model.

Information Technology Security Engineer at a tech services company with 11-50 employees

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.

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."

"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."

"The solution's support is one of the coolest things about the product. I"

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

"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."

"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."

"Thunder TPS has automated mitigation and fully managed support in case the device cannot handle the attack. They have engineers available to respond."

More A10 Thunder TPS pros

"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."

"The support team was helpful."

"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 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."

Cons

"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."

"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 is a little expensive."

"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."

"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."

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

More A10 Thunder TPS cons

"The solution must provide features for the post-processing of the traffic type and the traffic quality."

"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."

"The mitigation scope of Origin Protection is not fully efficient as there could be delays in activating the countermeasures."

"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."

"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."

Pricing and Cost Advice

"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.""

"Pricing is very reasonable."

"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 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."

"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."
