Advanced protection has secured critical web workloads and provides clear traffic visibility

From a security perspective, there remains a security loophole, as some browsers in the market can bypass the Turnstile solution, which requires approximately 40 seconds to do so. From a performance perspective, this is acceptable. We also tried Google reCAPTCHA, and that can also be bypassed. From a security perspective, I would say neither solution is completely secured. Regarding uptime, we have faced a couple of incidents due to Cloudflare in recent years, so I cannot say we receive 100% uptime for our region. We sometimes face challenges, including downtime and other issues. As a result, we are not receiving 100% uptime from Cloudflare's solution. Since most of our customers are in this region, we need alternatives. We need something more competitive than Cloudflare. Unfortunately, in Bangladesh, Cloudflare has three points of presence already, and we cannot find any other solution provider in Bangladesh as an alternative, which presents another challenge. Competitor solutions have more attack signatures, which ensure better security compared to Cloudflare's predefined configurations. Customers do not have options to modify any configuration parameters in Cloudflare, whereas other competitor solutions, such as F5 Distributed Cloud, allow customers to tune configurations according to their requirements. Cloudflare could improve in this area. Additionally, regarding visibility, Cloudflare has static visibility, but they could adopt dynamic graph features for their customers.

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.

Quotes from Members

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

Pros

"Cloudflare is very straightforward."

"Cloudflare allows us to self-host services such as Rocket.Chat and Node-RED, in high-availability mode, thanks to round robin DNS which allows us to share one hostname between our two locations."

"Cloudflare is easier to manage than the solutions provided by these vendors, and the user experience is much more straightforward and appeals to a lot of developers."

"The most valuable feature of the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present."

"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."

"The initial setup is extremely easy but will require access to your Domain Name Servers."

"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."

"The overall performance of this solution is what makes it one of the best solutions on the market."

More Cloudflare pros

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

"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."

"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."

"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."

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

"It is a scalable solution."

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

"The GUI is very use-friendly, you can configure it through CLI or GUI so they give you an option to choose, and it's a good solution in terms of the appliance itself because it's very light compared to other brands that offer DDoS solutions."

More A10 Thunder TPS pros

"We use it to protect our users and their data."

"The product's initial setup phase was really easy."

"It allows me to see all the traffic on my network."

"The most valuable feature is the cloud DDoS scrubbing capability."

"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."

"We have researched them all, and it's a good solution all around."

"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us, and this is important."

More Fortinet FortiDDoS pros

Cons

"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."

"Flexible SSL is nothing more than an illusion of security that you're presenting to your visitors."

"Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called abc.com and a subdomain called a.abc.com, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization."

"Access to the solution's dashboards is not intended for a service company. You are practically blind, and to validate a problem, you must view the customer's screen."

"I would like to not need a separate server for non-www redirection under the CNAME setup option."

"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."

"Support response time could be improved."

"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."

More Cloudflare cons

"The solution needs improvement in terms of fail-open."

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

"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 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."

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

"If there's one aspect of A10 that needs improvement it would be the training."

"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."

More A10 Thunder TPS cons

"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."

"The solution can be a little more user-friendly and it can be more affordable."

"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."

"I find that there have been issues in the past year with the solution hanging. It freezes often."

"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."

"The web interface could be much better."

"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."

"I would like to see analytics, big data."

More Fortinet FortiDDoS cons

Pricing and Cost Advice

"The price is reasonable."

"The solution is expensive when compared to other products but offers unlimited bandwidth."

"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."

"So far I use free tier and happy with it. You can subscribe to business package if needed."

"Cloudflare's pricing is not much higher and is good for middle-level organizations."

"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."

"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."

More Cloudflare 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."

"Pricing is very reasonable."

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

"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 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 was much higher with Arbor (APS) for the same type of solution."

"The product’s pricing needs improvement."

"The solution is reasonably priced."

"It's quite pricey."
