Customer Service

Sentiment score

Sentiment score
7.2
Cloudflare's support is praised for responsiveness, though non-paying users and regions without local offices face challenges.
The technical support was quick and accepted my requests.
The technical support team is very effective in resolving issues.
Although the team is good, they are not fast, and they lack the skills to manage dynamic attackers.
The technical support for Arbor DDoS is great, though sometimes it can be stalling.
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.
We'd like a dedicated account manager.
 

Scalability Issues

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
7.4
Arbor DDoS excels in scalable, efficient cloud and hardware-based mitigation for enterprises, though pricing and upgrades may challenge.
Sentiment score
8.2
Cloudflare efficiently handles increased traffic and growth, offering scalability, robust network performance, and seamless expansion for enterprises.
Without accessible documentation, setting up can be time-consuming.
This would enhance the knowledge about scalability options available for Arbor DDoS, making it more accessible and useful for users.
I find Arbor DDoS to be very scalable.
I rate its scalability a ten out of ten because I had no issues with it.
I rate the scalability a ten out of ten.
It is a SaaS tool, but the fact that they have workloads deployed across the world proves that it is a highly scalable tool.
 

Stability Issues

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
8.3
Arbor DDoS is praised for stability, occasional minor bugs, and consistent long-term performance despite configuration challenges.
Sentiment score
7.7
Cloudflare is generally stable and reliable, but occasional issues with downtime, speed, and DDoS protection are reported.
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

A10 Thunder TPS needs better training, smoother upgrades, improved documentation, and enhanced synchronization, with concerns over UI and virtual training.
Arbor DDoS needs improved mitigation, scalability, integration, pricing, and AI for better traffic handling and competitive advantage.
Cloudflare needs analytics, threat insights, improved support, user-friendly dashboards, and simplified pricing, with consistent caching and security features.
We had to find workarounds for issues like A10 blocking necessary traffic, sometimes leading to decreased security.
I would like to see an option to decrypt the traffic with Arbor DDoS, as some clients are interested in this, particularly for application layer attacks on port 443.
Enhancing the handshakes between Arbor DDoS and third-party solutions is essential for obtaining better and real-time data that supports any organization’s support team effectively.
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.
In future releases, one thing that would be great is if Cloudflare could provide basic WAF rules and security recommendations based on website scanning.
 

Setup Cost

Enterprise buyers find A10 Thunder TPS pricing mixed, highlighting both value and expense, with multiyear deals as beneficial.
Arbor DDoS pricing is high but justified, ideal for large enterprises requiring advanced features, yet costly for small businesses.
Cloudflare offers flexible pricing with plans for small businesses to enterprises, balancing cost with comprehensive features and protection.
The global price list is not accessible, making it difficult to work.
For some customers, the cost is expensive, but for enterprises looking to protect their services, it is affordable.
That's where Cloudflare shines for smaller businesses – it's ten times cheaper than Akamai.
I find it to be cheap.
It's cost-effective, but I think they should have a custom pricing model for enterprise customers based on the features you use.
 

Valuable Features

A10 Thunder TPS excels in traffic filtering, DDoS mitigation, load balancing, and offers programmable automated defense with RESTful API.
Arbor DDoS offers advanced features like automated mitigation, AI-based anomaly detection, and flexible integration to enhance security.
Cloudflare offers caching, DDoS protection, and CDN services, enhancing website speed and security with intuitive interface and global reach.
The vendor indicated that Thunder would not be supported, but I was able to add Thunder to the central console management.
The platform offers quick mitigation of attacks because Arbor DDoS uses BGP Flowspec, enabling very quick mitigation.
The most valuable feature was the ability to detect attacks within two seconds and gain visibility of all the traffic.
The feature I find most valuable is the packet capture, which beautifully shows the communication between the client and the server, identifying potential malicious activity.
Our scenario consisted of two web servers in different allocations to control access demands, and the load balancer did the job as expected, bringing security and stability to access points.
For me, the valuable feature is DDoS protection.
The most valuable features of the solution are performance and security.

A highly stable solution that can be used for load balancing
We contacted the solution's technical support to maintain and exchange the power supply. A few versions ago, we had some CPU and memory problems. We just started the appliance, and it was already on 70% of CPU usage. We first contacted our reseller in Brazil and then escalated the issue to A10 Thunder TPS support. The reseller in Brazil was a little slow, but the A10 Thunder TPS support was fast.

Rapid attack detection and traffic visibility improve security management
The solution was intended for the big clients of Telefonica to clean their internet pipe. We deployed the service to clean the pipe. In some clients' data centers, we implemented a solution that detects and mitigates attacks using Arbor DDoS, our data center solution For me, the most valuable…

It's easy to set up because you point the DNS to it, and it's working in under 15 minutes
Cloudflare is highly scalable. Cloudflare is a system with a web portal that the end users like me see. It's a console where we can adjust the DNS, caching, and security features all in that console. Cloudflare owns thousands of servers across the world that cache the data. It's a powerful solution. When clients sign up for Cloudflare, they're getting this monster content delivery network, security, and a web application firewall in one. It's all rolled into one, and it's massive. Unless you have your website hosted on a massive hosting provider, there's no way that you can deliver the amount of data that Cloudflare can provide to the end users. If you have static content, there's no way that you can ever match what Cloudflare can do. Obviously, there are competitors to Cloudflare that do the same, but I'm saying other types of solutions. Let's say you go with F5. Great, that's on-prem. That's in your colo. You can't deliver as much data to the internet as you can with a CDN. You don't have to spend $20,000 on a net scaler, F5, or whatever Cisco's selling now. You don't have to buy that. You pay them $50 a month or $150 a month. It's totally worth it because even in five years, you'll never get the performance value, not just the actual ROI. You have to consider how much throughput you can get with Cloudflare.
