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
6.1
Cloudflare's support is praised for responsiveness and effectiveness, though some Indian users face communication challenges and prefer local help.
Sentiment score
6.1
Citrix support is responsive and knowledgeable, though some users report delays and prefer direct access to experienced engineers.
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.
The technical support of Cloudflare Web Application Firewall rates between five and seven at maximum.
 

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
8.1
Cloudflare Web Application Firewall is praised for its scalability, flexibility, automation, and superior advantages compared to open-source solutions.
Sentiment score
7.8
NetScaler is praised for high scalability and flexibility, despite some challenges with licensing complexity and multi-tenancy support.
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.
 

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
8.4
Cloudflare Web Application Firewall is highly stable and reliable, ensuring uninterrupted, effective protection and user satisfaction.
Sentiment score
7.6
NetScaler is highly rated for stability and performance, with some recommending regular maintenance for optimal reliability.
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

Cloudflare requires improvements in analytics, CDN speed, API, technical support, DNS management, documentation, pricing clarity, and international and reseller support.
Cloudflare WAF must update features, improve documentation and support, reduce false negatives, and enhance usability, integrations, and visibility.
NetScaler needs improvements in usability, stability, security integration, and support while enhancing documentation, pricing transparency, and deployment processes.
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.
They need to improve their support because getting a response for basic requests took around 48 hours, which is too long.
 

Setup Cost

Cloudflare offers cost-effective, scalable plans with no setup fees, starting from free for small businesses to enterprise-level solutions.
Enterprise users find Cloudflare's Web Application Firewall competitively priced, reasonable, and transparent despite starting fees and optional features.
NetScaler pricing is high but offers strong features; cost-saving options include alternatives or negotiating multi-year subscriptions.
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.
Cloudflare WAF offers API configurability, comprehensive features, robust security, scalability, with strong integration and technical support.
NetScaler provides flexible deployment, security enhancements, and integration with Citrix for efficient application delivery and robust traffic management.
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.

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.
DEMİRHAN ÇAVUŞOĞLU - PeerSpot reviewer
A tool for centralized management including inventory and sales tracking
Citrix ADM has the ability to implement policies to tighten security. For instance, you can restrict access to your network from outsiders or lack necessary security measures such as antivirus programs. Additionally, there's the Delivery Controller, which allows for comprehensive monitoring and management tasks such as remote restarts, maintenance, and registration. Another essential component is the Director, which provides detailed insights into sessions, including identifying session failures, connection issues, user lockouts, etc. It presents a list of problems to address, enabling you to click on them and resolve them efficiently.
