This would help us address issues promptly, especially during unforeseen events like DDoS attacks.

We'd like a dedicated account manager.
Their support team is responsive, and they deliver timely updates, addressing any glitches promptly.

I rate the scalability a ten out of ten.
It is a SaaS tool, but the fact that they have workloads deployed across the world proves that it is a highly scalable tool.
F5 Silverline Managed Services is scalable enough without observed limitations.
The solution is fully scalable, and I would give it a rating of ten on a scale of one to ten for scalability.

Room For Improvement

Cloudflare needs analytics, threat insights, improved support, user-friendly dashboards, and simplified pricing, with consistent caching and security features.
F5 Silverline needs improved pricing, integration, user interfaces, automation, API, and enhanced features like AI and bot detection.
Microsoft Azure Application Gateway requires better pricing, integration, ease of use, documentation, support, and enhanced features for scalability and security.
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.
Introducing preemptive support prompts would reduce the manual effort required for creating policies or blocking specific IPs.
Improvements could include the creation of highly optimized profiles.
There is room for improvement in terms of support, such as assigning agents directly for more straightforward engagement.
 

Setup Cost

Cloudflare offers flexible pricing with plans for small businesses to enterprises, balancing cost with comprehensive features and protection.
Enterprise users view F5 Silverline pricing as competitive but costly, with room for negotiation and flexible licensing options.
Microsoft Azure Application Gateway's cost is mixed, valued for integration but often seen as pricey, averaging a seven rating.
That's where Cloudflare shines for smaller businesses – it's ten times cheaper than Akamai.
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.
On a scale where ten is very expensive, I would rate the pricing as three.
The solution is expensive
Azure solutions are quite expensive.
 

Valuable Features

Cloudflare offers caching, DDoS protection, and CDN services, enhancing website speed and security with intuitive interface and global reach.
F5 Silverline Managed Services provides easy setup, robust security features, excellent scalability, and effective DDoS protection with comprehensive reporting.
Microsoft Azure Application Gateway offers Layer 7 management, WAF security, API-based routing, easy integration, and cost-efficient performance.
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.
It allows for centralized management of certificates, protecting applications from top ten attacks like SQL injection and cross-site scripting.
The monitoring tab displays GET and POST requests in a readable format, making it accessible even to non-tech-savvy individuals.
We are using it for some of the security features for our applications, particularly for securing traffic in transit with SSL.

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.

Mitigates more bot activity when defending web applications than any other vendor but comes at a price
F5 Silverline Managed Services is expensive. You do get world-class quality of mitigation, but I think it is still pricey. You can find similar services, potentially of slightly lower quality, from other vendors like Cloudflare or Akamai for about half the price. When you compare what you get for the money you spend at Cloudflare or Akamai, you do get less protection but you are not dishing out too much for it. On the other hand, at F5 Silverline Managed Services, you do get better protection but, but you are paying double for it. We have had mixed feedback from our clients about this. Most of them would rather pay less for a bit of a lower-quality defense than overshoot their budget. The most common piece of feedback we receive is that the difference in protection levels is not reflected in the price.

Offers time and cost savings with integration, but user interface needs improvement
We are using it for our internal application development. We are testing those features of application gateways. We are integrating it with our solutions, application, Azure Application Gateway Microsoft has a vast variety of tools, and it blends very well. It provides a range of services, so it…
