Review summaries and opinions

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

ROI

Sentiment score
6.5
Cloudflare enhanced speed, security, and data protection, providing significant ROI and improved operations and client satisfaction for businesses.
Sentiment score
6.4
Tenable Cloud Security is praised for cost-effectiveness, yielding positive ROI and satisfactory financial benefits despite limited specific metrics.
WordPress security can be tricky, and that's where Cloudflare can be absolutely helpful for small businesses.
For the small project I was working on, using the basic tier provided a huge improvement at zero cost.
 

Customer Service

Sentiment score
7.0
Cloudflare's customer service is efficient for paying users, but responses can vary in speed and effectiveness for others.
Sentiment score
3.9
Tenable Cloud Security support receives mixed reviews, praised for responsiveness but criticized for delays and inconsistency in assistance.
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.
The key factor is the language in which the support is offered, which, in this case, is in Thai.
 

Scalability Issues

Sentiment score
8.1
Cloudflare is praised for seamless scalability, managing enterprise-level traffic efficiently and earning high customer satisfaction during peak events.
Sentiment score
6.4
Tenable Cloud Security is praised for its scalability and adaptability, although complex multi-cloud asset management requires improvements.
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.
 

Stability Issues

Sentiment score
7.6
Cloudflare is widely regarded as stable and reliable, with improvements noted in uptime and performance on higher plans.
Sentiment score
7.7
Tenable Cloud Security is stable with high user ratings, though some suggest minor improvements despite no major outages.
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 requires improvements in analytics, CDN speed, API, technical support, DNS management, documentation, pricing clarity, and international and reseller support.
Tenable Cloud Security needs faster operations, improved support, detailed reporting, AI integration, and easier multi-cloud implementation.
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.
Cloudflare should add more documentation and pricing to the cloud version.
The only complaint I hear in the market is from resellers that Tenable management team in Brazil doesn't play fair with the channel and resellers.
 

Setup Cost

Cloudflare offers cost-effective, scalable plans with no setup fees, starting from free for small businesses to enterprise-level solutions.
Users find Tenable Cloud Security's subscription model reasonably priced and well-suited for enterprises, offering good value compared to competitors.
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.
 

Valuable Features

Cloudflare enhances security, speed, and SEO with easy-to-use features like CDN, SSL, DDoS protection, and centralized management.
Tenable Cloud Security offers comprehensive vulnerability detection, deep cloud analysis, IAM features, and multi-cloud integration into a single dashboard.
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.
Perhaps the best functionalities are related to promoting a deeper analysis of the environment where applications are running in terms of creating a double armor of security to block threats that may come in the cloud with Tenable Cloud Security.
The best features Tenable Cloud Security offers in my experience are automatic scanning, frequent scanning, and automatic finding, which I find valuable.

Featured Reviews

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.
Antonio Scola - PeerSpot reviewer
Offers reliable security support and encourages a safe migration to cloud environments while there is room for better reseller collaboration
I really don't know to tell the truth because we sell many solutions and don't sell exclusively Tenable, so I'm not in a condition to give a precise definition of what could be improved. My perception is this: when customer A needs Tenable Cloud Security, we introduce and demonstrate it. They POC, they appreciate it. The solution serves in such use cases ABC. I am very pragmatic and straightforward - as long as they use or want the solution, I am interested. If they don't, my question is what are the main objections? They may discuss pricing, or they may say they thought the solution had certain technical capabilities that they could not find.
