Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
6.5
Cloudflare users experienced increased performance, security, and cost-effectiveness, leading to improved loyalty and revenue despite difficult ROI calculations.
Sentiment score
6.6
F5 Silverline Managed Services offers effective cybersecurity solutions, with variable ROI perceptions and appreciation for time and cost savings.
Sentiment score
7.0
HAProxy offers cost-effective traffic management, enhanced efficiency, and high ROI through streamlined processes and reduced manual intervention.
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.
Operational efficiency has improved; we no longer have staff consistently monitoring backend servers during deployment or scaling events, as HAProxy's health checks and hitless reloads allow us to push changes with minimal manual intervention.
 

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
6.1
F5 Silverline's customer support is responsive but varies; users praise personalization but note challenges with escalations and response times.
Sentiment score
6.6
HAProxy's customer service is swift and effective, but open-source support lacks the comprehensiveness of enterprise alternatives.
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.
I would rate the technical support with Cloudflare as excellent every time I've had to call them.
Their support team is responsive, and they deliver timely updates, addressing any glitches promptly.
They resolve the issues by joining me to fix them.
Since we are utilizing the open-source edition, community forums, mailing lists, and GitHub have been invaluable, with typically someone having encountered the same problems we faced.
 

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
7.8
F5 Silverline offers scalable managed services, efficiently handling enterprise demands with flexible expansion and seamless capacity management.
Sentiment score
7.8
HAProxy is praised for its scalability, efficiency, and flexibility, handling thousands of connections and supporting mid-sized deployments seamlessly.
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.
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.
HAProxy's scalability is excellent; as our traffic expands, it handles load increases effortlessly.
 

Stability Issues

Sentiment score
7.6
Cloudflare is highly rated for stability and uptime, with few past issues, especially on higher-tier plans.
Sentiment score
7.3
F5 Silverline delivers stable performance with strong monitoring, minimal downtime, effective support, and high stability ratings despite occasional issues.
Sentiment score
8.2
HAProxy is highly stable, reliably managing heavy traffic with minimal downtime, efficient support, and consistent functionality improvements.
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.
They offer regular updates, and overall, I would rate the stability of the solution as nine out of ten.
This reliability serves as a key reason for our choice, providing us with confidence even when faced with heavy traffic.
 

Room For Improvement

Enhancements needed in Cloudflare: analytics, CDN latency, API integration, user support, DNS, pricing, documentation, server coverage, WAF, and cache.
F5 Silverline needs improved pricing, integration, user interfaces, automation, API, and enhanced features like AI and bot detection.
HAProxy needs better GUI, dynamic configuration, user-friendly logging, REST API, cloud integration, security, and community features.
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.
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.
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.
The configuration syntax is powerful yet can become overwhelming for newcomers; a more beginner-friendly interface or a native GUI without relying on third-party tools would ease the onboarding process.
An easier desktop interface to connect to a remote server and make changes on my PC would be beneficial.
 

Setup Cost

Cloudflare offers scalable pricing, from free to enterprise plans, providing significant value especially for mid-sized companies.
Enterprise users view F5 Silverline pricing as competitive but costly, with room for negotiation and flexible licensing options.
HAProxy is cost-effective, praised for simple licensing, robust features, and valued by enterprises despite requiring expertise for setup.
That's where Cloudflare shines for smaller businesses – it's ten times cheaper than Akamai.
I find it to be cheap.
The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive.
On a scale where ten is very expensive, I would rate the pricing as three.
The solution is expensive
Since we use the open-source edition, there are no licensing fees, with the main cost being the infrastructure running on EC2 instances in AWS, which helps maintain low expenses.
Setting up HAProxy didn't cost anything for me.
 

Valuable Features

Cloudflare enhances performance and security with CDN caching, DDoS protection, and an easy-to-use dashboard, benefiting many users.
F5 Silverline Managed Services provides easy setup, robust security features, excellent scalability, and effective DDoS protection with comprehensive reporting.
HAProxy is praised for its excellent load balancing, reliability, customization, scalability, advanced traffic rules, and open-source integration.
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.
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.
By moving all SSL termination to the load balancer, I now manage certificates in a single place, and I can also utilize Let's Encrypt with HAProxy's built-in ACME support, making renewal automatic.
The best features HAProxy offers for my setup are easy configuration, as I don't need to set up many things; I just installed it and write configurations based on my needs.

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.
DejanBlagojevic - PeerSpot reviewer
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.
Mehdi El Filahi - PeerSpot reviewer
Useful for for small and quick load-balancing tasks
What I like best about the product is its simplicity and speed. When you need to set up a load balancer quickly, HAProxy offers options like sticky sessions and round-robin. It's also fast to configure, including adding SSL for security. While it may have fewer options than other solutions like F5, HAProxy gets the job done for basic load-balancing tasks. The reliability features of HAProxy were particularly useful in a scenario where I needed to test load balancing between two Tomcats. Since these domains were inaccessible, I set up a third Docker with HAProxy, which had access to the Tomcat domains. I then configured HAProxy to handle the load balancing. This setup allowed the client to interact with HAProxy. The solution's integration with other elements is easy.
