Sentiment score
7.0
A10 Thunder TPS support is praised for timely responses, effective resolutions, proactive fixes, and handling complex issues efficiently.
Sentiment score
7.1
Imperva DDoS offers professional customer service with some delays; enterprise support is effective, technical support sometimes needs escalation.
This would help us address issues promptly, especially during unforeseen events like DDoS attacks.
Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model.
You can get a support engineer with the best qualifications.
The technical support was quick and accepted my requests.
 

Scalability Issues

Sentiment score
8.2
Cloudflare efficiently handles increased traffic and growth, offering scalability, robust network performance, and seamless expansion for enterprises.
Sentiment score
6.9
A10 Thunder TPS provides scalable, flexible defenses for global data centers, supporting large traffic volumes for medium-sized enterprises.
Sentiment score
7.9
Imperva DDoS offers highly scalable, adaptable solutions with seamless expansion, efficiently handling large attacks, though scaling costs may be high.
It is a SaaS tool, but the fact that they have workloads deployed across the world proves that it is a highly scalable tool.
The tool offers very good performance, even during high-traffic periods.
I rate the solution’s scalability an eight out of ten.
Without accessible documentation, setting up can be time-consuming.
 

Stability Issues

Sentiment score
7.7
Cloudflare is generally stable and reliable, but occasional issues with downtime, speed, and DDoS protection are reported.
Sentiment score
8.2
The A10 Thunder TPS offers consistent stability, high availability, and positive user feedback, with reliability enhancements and successful maintenance.
Sentiment score
7.7
Imperva DDoS is highly reliable with consistent uptime, minor issues, and positive user sentiment regarding its stability.
For DDoS protection, I would not recommend Cloudflare.
I rate the solution’s stability an eight out of ten.
The service is very stable with no impacts during high-traffic periods.
 

Room For Improvement

Cloudflare needs analytics, threat insights, improved support, user-friendly dashboards, and simplified pricing, with consistent caching and security features.
A10 Thunder TPS needs better training, smoother upgrades, improved documentation, and enhanced synchronization, with concerns over UI and virtual training.
Imperva DDoS requires improvements in customer support, pricing, interface design, security features, latency management, and enhanced documentation.
There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features.
Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor.
It doesn't work if you want to look up the hostname from an IPA address.
We had to find workarounds for issues like A10 blocking necessary traffic, sometimes leading to decreased security.
 

Setup Cost

Cloudflare offers flexible pricing with plans for small businesses to enterprises, balancing cost with comprehensive features and protection.
Enterprise buyers find A10 Thunder TPS pricing mixed, highlighting both value and expense, with multiyear deals as beneficial.
Imperva DDoS offers competitive pricing with flexible options, but can be costly compared to Cloudflare or Akamai.
That's where Cloudflare shines for smaller businesses – it's ten times cheaper than Akamai.
I find it to be cheap.
I think they should consider reevaluating the pricing for support, as it can be quite high.
The global price list is not accessible, making it difficult to work.
 

Valuable Features

Cloudflare offers caching, DDoS protection, and CDN services, enhancing website speed and security with intuitive interface and global reach.
A10 Thunder TPS excels in traffic filtering, DDoS mitigation, load balancing, and offers programmable automated defense with RESTful API.
Imperva DDoS provides robust, easy-to-use protection against attacks with advanced security measures and real-time traffic analysis.
The most valuable features of the solution are performance and security.
Techniques like minification and image compression reduce the size of assets, leading to better performance and faster user load times.
The solution has been able to compare it to the market, and I think the product has taken great strides in automating quite a bit of things, and they use a lot of AI.
The vendor indicated that Thunder would not be supported, but I was able to add Thunder to the central console management.

Carlos Alam Hernandez Baruch - PeerSpot reviewer
Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.
RonaldoDE Melo - PeerSpot reviewer
Useful for protecting and supporting users against attacks
One problem for me with A10 Thunder TPS is that the box comes from another country in Brazil. In the tool, there is no one key to block it. For example, in F5 Networks, we have a key. If you try to buy another box from Huawei or from F5 and try to enable them in A10 Thunder TPS, you need a key to do 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.
DerrickAkankwasa - PeerSpot reviewer
Provide DDoS protection and better security at effective rate
It is expanding its number of data centers for scrubbing traffic. Currently, there is only one POP for cleaning in South Africa. They might add another POP in North Africa, possibly in Nigeria or Egypt. Latency concerns customers, especially in regions like East and West Africa, where traffic has to travel to South Africa before returning. Increasing the number of POPs across the continent would help address these latency issues and improve overall service. While the platform is already quite strong, there’s always room for improvement, especially in keeping up with emerging trends and new types of attacks. Enhancing security capabilities could be beneficial. Integrating more advanced AI features could significantly improve its effectiveness and help customers leverage these tools more effectively. It would be great to see more focus on AI integration to handle and analyze data more efficiently.
