Room For Improvement

Cloudflare needs analytics, threat insights, improved support, user-friendly dashboards, and simplified pricing, with consistent caching and security features.
F5 BIG-IP LTM is expensive, complex, lacks pay-as-you-grow, with room for improving support, integrations, and user-friendliness.
Fortinet FortiWeb needs enhancements in throughput, cloud presence, integration, and user-friendly features to improve competitiveness and scalability.
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.
The cloud-based security service of Fortinet FortiWeb could be enhanced to match the level of providers like Cloudflare.
 

Setup Cost

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.
The product is costly.
Fortinet FortiWeb is cost-effective compared to solutions like F5.
 

Valuable Features

Cloudflare offers caching, DDoS protection, and CDN services, enhancing website speed and security with intuitive interface and global reach.
F5 BIG-IP LTM enhances application performance with load balancing, iRules, SSL offloading, and customizable, intuitive interface for complex environments.
Fortinet FortiWeb offers advanced security features with seamless integration, intuitive interface, and enhanced threat detection using AI and machine learning.
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.
One of the most beneficial features of F5 BIG-IP Local Traffic Manager (LTM) is its ability to identify compromised traffic and its capabilities in authentication.
The machine learning-based threat detection is significant, as it uses a learning method that eases the configuration burden, making it very useful.

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.

Identifying compromised traffic and securing data has been a significant advantage
One of the most beneficial features of F5 BIG-IP Local Traffic Manager (LTM) ( /products/f5-big-ip-local-traffic-manager-ltm-reviews ) is its ability to identify compromised traffic and its capabilities in authentication. Additionally, the security aspect of it provides a significant advantage as it helps us secure our data, which is a major investment and benefit for us. Before using this system, we had difficulties in storing our data and managing the traffic that comes in and out.
Kacem CHAMMALI - PeerSpot reviewer
Even if an attacker detects the IP address, they can't connect directly to the server due to FortiWeb
The xFF, or X-Forwarded-For feature, IP reputation, and protected hostname. We can block access using the IP address, so no one can connect to our web server or website using the real IP. They need to use the FQDN instead. Even if an attacker detects the IP address, they can't connect directly to the server due to FortiWeb and the option to protect the hostname. All traffic passes through FortiWeb. Machine learning capabilities in FortiWeb: I don't use machine learning all the time. In the initial phase of FortiWeb deployment, we use the learning process to detect the traffic passing through FortiGate to our website.
