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.

Optimized ecommerce performance and improved access control through image handling and IP filtering

I believe that Fastly should provide guidelines for their WAF blocking rules. It should be public what the rules are that are blocking their contents. I believe Fastly should provide regional IP addresses instead of POP IPs. Fastly should provide features similar to Cloudflare regarding a block list. Additionally, a POP address should be there with a wide range of IP addresses provided, public static IP addresses, so customers can integrate egress IPs. Fastly should provide WebP image processing on the backend instead of on the fly. It would be a very useful feature to avoid unnecessary time for browser to browser and local cookies. I believe that Fastly service has a few gaps. We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers. There should be transparency.

Quotes from Members

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

Pros

"The product's initial setup phase is very simple."

"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."

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

"They give us the ability to configure many features for DDoS. There are many items that we can use."

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

"We can keep track of all the customer's requirements. We can forecast our trails and we can forecast our overall financial things."

More A10 Thunder TPS pros

"Its initial setup process is straightforward."

"Fastly provides CDN, WAF, image optimization, and IP restriction."

"Compute@Edge features are valuable to me."

"The product helps our organization to access sites located in different regions quickly."

"Support is good; the product works as advertised. We have a Slack connection with them. So we can basically ask for help, live, engage, and ring when they respond. Very quickly."

"Fastly combines both the CDN side and the Signal Sciences next-generation WAF, which is closely integrated with the CDN, allowing us to use both products seamlessly."

"Rate limiting is a good feature that protects from volumetric attacks."

"The product's initial setup phase is straightforward."

More Fastly 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 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 would like for them to develop an advanced reporting feature."

"Its documentation could be better."

"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."

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

"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."

More A10 Thunder TPS cons

"Stronger analytics would be helpful, like showing configurations that haven't served a certain amount of traffic in a while. With many properties, things can get lost track of - duplicates or unused configurations not properly decommissioned."

"The solution's pricing could be better."

"The product should provide improved bot detection and management."

"Fastly's customer service area needs improvement."

"It is missing a "staging" platform to deploy a test configuration with all of the real settings, which would allow us to properly test before putting it into production."

"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."

"Support is not that great."

"What I don't like about Fastly is that they charge a heavy price."

Pricing and Cost Advice

"Pricing is very reasonable."

"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."

"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.""

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

"It is an expensive solution."

"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."

"You need to pay a premium price for the tool."

"The pricing has been very competitive."

"The solution is cheaper than other products in the market."

"In my opinion, Fastly is priced competitively."

"Fastly is less expensive than one of its competitors."
