In terms of return on investment with Cloudflare, it costs my time to set them up, but basically once they're set up, it's done.

Customer Service

Sentiment score

Cloudflare's customer service is praised for promptness, but technical support feedback varies, especially favoring Enterprise tier users.

Tenable Cloud Security support receives mixed reviews with praised efficiency and availability, but some note delayed and inconsistent assistance.
Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model.
Senior Consultant CDN at a comms service provider with 10,001+ employees
I would rate the technical support with Cloudflare as excellent every time I've had to call them.
Owner at Hga consulting
We use other solutions where support is available through Slack channels and is more interactive, with someone responding within a couple of minutes or seconds.
General Manager at bKash Limited
With Element, if you need a feature, you can discuss it with them, and if implementation is possible, you will have that feature within a month or two, depending on complexity.
Information Security Architect at WSP

7.9
Users praise Cloudflare's scalability, flexibility, and seamless tier transitions for maintaining high performance under increasing traffic and demands.

Tenable Cloud Security excels in scalability, praised for handling assets efficiently, but faces challenges in larger multi-cloud setups.
It is a SaaS tool, but the fact that they have workloads deployed across the world proves that it is a highly scalable tool.
Principal Cyber Prevent and Defense Engineer at a comms service provider with 1,001-5,000 employees
The tool offers very good performance, even during high-traffic periods.

Room For Improvement

Cloudflare needs enhancements in speed, support, reliability, pricing, and documentation, while expanding integration, security, and analytics capabilities.
Tenable Cloud Security needs improved speed, automation, integration, clearer licensing, better support, and AI-powered features for multi-cloud environments.
Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor.
Managed Services Manager at Adapture Technology Group
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.
General Manager at bKash Limited
Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements.
Senior Cloud Solution Architect at Integrated Technology Solution Group (ITSG)
Adding capabilities for the scanner to automatically pick up changes and add assets automatically would be valuable.
Information Security Architect at WSP
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.
Owner at SUNLIT TECHNOLOGIES
 

Setup Cost

Enterprise users find Cloudflare cost-effective, with valuable upgrades and competitive pricing, despite unclear enterprise price lists.
Tenable Cloud Security is favorably received for its fair pricing, offering good value for enterprise cloud security solutions.
I find it to be cheap.
Engineer at SITMEXICO
I rate the product’s pricing a five out of ten, where one is cheap, and ten is expensive.
Senior Solutions Architect at Think Power Solutions
The tool is a premium product, so it is very expensive.
Principal Cyber Prevent and Defense Engineer at a comms service provider with 1,001-5,000 employees
 

Valuable Features

Cloudflare provides caching, DDoS protection, and CDN services with enhanced security features, making it vital for optimized web performance.
Tenable Cloud Security offers comprehensive vulnerability detection, asset management, and integration, enhancing security and compliance with proactive monitoring.
The most valuable features of the solution are performance and security.
Senior Cloud Solution Architect at Integrated Technology Solution Group (ITSG)
Techniques like minification and image compression reduce the size of assets, leading to better performance and faster user load times.
Senior Solutions Architect at Think Power Solutions
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.
Principal Cyber Prevent and Defense Engineer at a comms service provider with 1,001-5,000 employees
The automatic integration capabilities, particularly with DNS, Azure, and AWS, are extremely valuable.
Information Security Architect at WSP
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.
Owner at SUNLIT TECHNOLOGIES
The best features Tenable Cloud Security offers in my experience are automatic scanning, frequent scanning, and automatic finding, which I find valuable.

Featured Reviews

M.A. Faisal - PeerSpot reviewer
General Manager at bKash Limited
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.

Has significantly improved proactive monitoring through automated asset discovery and seamless integration with cloud environments
Making the system smarter would be beneficial. Adding modules for integration with AWS and Azure would be helpful. Adding capabilities for the scanner to automatically pick up changes and add assets automatically would be valuable. When discussing a big company, it is mandatory to have tools that will assist us rather than waiting for manual input to add hosts. Adding assets manually is prone to mistakes. Humans might forget to add an asset or make errors when adding multiple assets. Taking the human element out of the context and making it more streamlined is the future for security. The human should be involved where expertise is needed, such as analysis and decision-making. Currently, with resource constraints, we need tools to collect and aggregate data, eliminate false positives as much as possible, and present relevant information to employees for action.
