Cloudflare users experienced increased performance, security, and cost-effectiveness, leading to improved loyalty and revenue despite difficult ROI calculations.
Sentiment score
7.6
Cloudflare WAF offers essential protection with cost-effective features, supporting various platforms and enhancing website visibility and uptime.
Sentiment score
7.8
F5 Advanced WAF provides high ROI with scalable security, efficient onboarding, regulatory compliance, and strong data protection.
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.
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.
My experience with the pricing or licensing of Cloudflare Web Application Firewall is that many features can be accessed for free, so the pricing is definitely reasonable.
Subscription models offer clearer ROI due to a more competitive pricing scheme.
 

Customer Service

Sentiment score
7.0
Cloudflare's customer service is quick, but technical support feedback is mixed, with improvement needed in responsiveness and detailed assistance.
Sentiment score
6.3
Cloudflare Web Application Firewall's support is praised for responsiveness and helpfulness, despite challenges with contact and Indian support.
Sentiment score
7.1
F5 Advanced WAF support is professional, helpful, but needs quicker responses; higher SLAs offer faster service and better experience.
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.
I would rate the technical support with Cloudflare as excellent every time I've had to contact them.
The technical support of Cloudflare Web Application Firewall rates between five and seven at maximum.
If there is a bug, the support is usually understanding and resolves issues.
I have interacted with F5's support, and while I have no major complaints, they could improve.
 

Scalability Issues

Sentiment score
8.1
Users praise Cloudflare for seamless scalability, effective traffic management, easy upgrades, and robust global infrastructure without disruptions.
Sentiment score
7.7
Cloudflare Web Application Firewall excels in scalability and ease of use, supporting large user bases efficiently with minimal management.
Sentiment score
7.6
F5 Advanced WAF excels in scalability and adaptability, supporting diverse applications, ideal for medium to large enterprises.
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.
The scalability of Cloudflare Web Application Firewall rates between 8 to 9, as it depends upon the use cases and what exactly the client needs.

Sentiment score
7.6
Cloudflare is highly rated for stability and uptime, with few past issues, especially on higher-tier plans.
Sentiment score
8.1
Cloudflare Web Application Firewall is praised for its reliable performance, minimal downtime, and effective security features across industries.
Sentiment score
8.5
F5 Advanced WAF is praised for stability and reliability, scoring highly in sectors like banking and telecom.
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.
The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10.
 

Room For Improvement

Enhancements needed in Cloudflare: analytics, CDN latency, API integration, user support, DNS, pricing, documentation, server coverage, WAF, and cache.
Cloudflare's Web Application Firewall requires ModSecurity upgrades, improved logging, integration, accuracy, more controls, and better documentation.
F5 Advanced WAF needs easier interfaces, better integration, enhanced support, and improved features for user-friendliness and efficiency.
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.
The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client.
The product can improve by having more multitenancy capability, which is currently not available.
I think they're doing a good job with DNS and as support for any domains that I create or that my clients create, it's mandatory for me to ensure they have Cloudflare as their DNS provider.
They need to improve their support because getting a response for basic requests took around 48 hours, which is too long.
Deployment training for F5 Advanced WAF is lacking and restricts growth by being inaccessible and costly for partners.
 

Setup Cost

Cloudflare offers scalable pricing, from free to enterprise plans, providing significant value especially for mid-sized companies.
Cloudflare's WAF offers competitive pricing from $20 to $10,000, seen as cost-effective but could improve transparency.
F5 Advanced WAF is costly but valued for its advanced features, comprehensive protection, and flexibility in high-stakes environments.
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.
Subscription models have competitive pricing, while perpetual licenses involve an upfront higher cost.
The price is affordable and satisfactory.
 

Valuable Features

Cloudflare enhances performance and security with CDN caching, DDoS protection, and an easy-to-use dashboard, benefiting many users.
Cloudflare Web Application Firewall provides scalable DDoS protection, configurable rules, advanced features, and comprehensive support with minimal false positives.
F5 Advanced WAF offers comprehensive protection with integration, customization, and features like network intelligence, DDoS prevention, and behavior 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 custom rules and the geo-redundant geographical rule feature, which allows me to implement geographical rules for customers, add significant value.
The best features of Cloudflare Web Application Firewall are multiple, including the WAF, rate limiter, and bot attack protection.
Cloudflare Web Application Firewall's advanced reporting and analytics tools add a layer that we're able to visualize and see before it actually hits the local firewall.
The perpetual license, despite an initial higher cost, lacks transparency regarding support expiration.
It contains the logic of both negative and positive security combined.

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.
SachidDoshi - PeerSpot reviewer
Offers a huge signature repository and is superiorly effective in mitigating DDoS attacks
The solution's learning curve can still be further reduced, which presently stands at two or three months. The product has a custom rule set that users can modify and manifest as needed. The vendor can probably shorten the learning curve using cutting-edge technologies like AI. The solution provider can also work around the web applications and identify the toolset that needs to be implemented to deploy the solution in less time. The vendor has launched a SASE product that can function with Cloudflare Web Application Firewall, but many improvements are needed in terms of features, such as the web filtering feature, and CASB has not yet been added.
Ahmed Moamen - PeerSpot reviewer
Protects applications with versatile authentication features
F5 offers a versatile solution that can be integrated with APM in cases where integration with an external IDB is needed. It is useful for authentication backup if the on-prem directory service is unavailable. Additionally, its WAF functionality is valuable for protecting applications from attacks. It is a versatile and strong solution that's easy to understand and deploy.
