ROI

Sentiment score
7.6
F5 Advanced WAF offers ROI by saving time, reducing costs, enhancing security, and ensuring compliance for businesses.
Sentiment score
7.2
HAProxy boosts efficiency by reducing costs and staff needs, offering speed, reliability, and enhanced scalability for traffic management.
Time savings in daily operations come from the automatic learning and signature update reducing the need for constant manual rule management, allowing the security and network teams to spend significantly less time handling false positive application-related escalations.
Cyber Security Consultant at HR Software Solution
Subscription models offer clearer ROI due to a more competitive pricing scheme.
Global Channel Alliances Lead at a tech vendor with 10,001+ employees
The amount of attacks it protects against is immense, more than F5 Advanced WAF itself costs.
Security Solutions Architect at a consultancy with 1-10 employees
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.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
This resulted in a drastic decrease in costs and, at the same time, the accuracy of the hits coming on HAProxy was almost around 100% or 99.99%.

Customer Service

Sentiment score
6.9

Senior Security Systems Engineer at a tech services company with 11-50 employees
I can run it in HA mode or even divide the traffic volume to the number of instances that I have based on their resource sizing.
Security Solutions Architect at a consultancy with 1-10 employees
We manage an automatic load balancing feature where we add HAProxy servers dynamically behind the application load balancer to handle more traffic.
Head of DevOps at TripFactory
HAProxy's scalability is excellent; as our traffic expands, it handles load increases effortlessly.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
For scalability, HAProxy meets my needs, supporting our initial horizontal scaling and then adapting to vertical scaling in a VMware environment.

Stability Issues

Sentiment score
8.4

Sentiment score
8.1
HAProxy offers high stability and reliable performance, enhancing system uptime with minimal downtime and frequent functionality updates.
F5 Advanced WAF has been very reliable and consistent for us; in our on-premise enterprise setup, it has been stable and predictable in day-to-day operations without any unexpected crashes or WAF-related downtime in production.
Cyber Security Consultant at HR Software Solution
F5 Advanced WAF is stable, and there is no doubt it is one of the best WAFs in the market.
Senior Security Systems Engineer at a tech services company with 11-50 employees
F5 Advanced WAF is pretty stable.
Security Solutions Architect at a consultancy with 1-10 employees
This reliability serves as a key reason for our choice, providing us with confidence even when faced with heavy traffic.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
The hot reload feature of HAProxy also really helped us so that we never had to shut it down to reload it.
CEo at CloudPositive
We have reduced a lot of servers, replacing them with one or two HAProxy servers which deliver better performance, accuracy, and an almost 100% success rate with requests.
Head of DevOps at TripFactory
 

Room For Improvement

F5 Advanced WAF needs improvements in pricing, usability, API protection, bot detection, deployment, and advanced integration features.
Users recommend improved HAProxy documentation, management tools, dynamic configuration, cloud integration, APIs, and enhanced load-balancing and clustering capabilities.
Deployment training for F5 Advanced WAF is lacking and restricts growth by being inaccessible and costly for partners.
Global Channel Alliances Lead at a tech vendor with 10,001+ employees
Overall, these are not blockers, merely enhancement opportunities, and once tuned, F5 Advanced WAF is very stable and reliable; improving usability, reporting, and onboarding would make it even more effective for larger environments.
Cyber Security Consultant at HR Software Solution
Another improvement could be refining the bot detection to minimize false positives; it should be able to verify more granularly between legitimate and non-legitimate clients.
Senior Security Systems Engineer at a tech services company with 11-50 employees
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.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
An easier desktop interface to connect to a remote server and make changes on my PC would be beneficial.
DevOps engineer at a tech services company with 1-10 employees
The reloading functionality is effective as it allows soft reloads without interrupting traffic patterns.
Principal Engineer Manager at a manufacturing company with 501-1,000 employees
 

Setup Cost

Enterprise buyers find F5 Advanced WAF's pricing high but justified in banking, with complex licensing and higher setup costs.
Enterprise buyers find HAProxy cost-effective, with free open-source options and a pricier Enterprise Edition offering enhanced features.
Licensing is capacity-driven, so you need careful planning based on traffic volume and use cases, and adding features such as Bot Protection impacts costs; once licensing is clear and sized correctly, there are no surprises.
Cyber Security Consultant at HR Software Solution
Subscription models have competitive pricing, while perpetual licenses involve an upfront higher cost.
Global Channel Alliances Lead at a tech vendor with 10,001+ employees
The price is affordable and satisfactory.
CEO at CyberApp
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.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
Setting up HAProxy didn't cost anything for me.
DevOps engineer at a tech services company with 1-10 employees
The pricing remains competitive compared to other vendors.
Principal Engineer Manager at a manufacturing company with 501-1,000 employees
 

Valuable Features

F5 Advanced WAF offers robust application security with bot protection, DDoS mitigation, and customizable threat detection for improved efficiency.
HAProxy offers high performance load balancing with customization, scalability, and support for diverse environments, enhancing user experience and flexibility.
The Advanced Attack Signature database is very strong and regularly updated, effectively blocking SQL injections, cross-site scripting, command injections, and file inclusion attacks while allowing selective enabling or disabling of signatures to avoid blocking genuine traffic.
Cyber Security Consultant at HR Software Solution
The perpetual license, despite an initial higher cost, lacks transparency regarding support expiration.
Global Channel Alliances Lead at a tech vendor with 10,001+ employees
It contains the logic of both negative and positive security combined.
CEO at CyberApp
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.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
HAProxy positively impacted our organization by exceeding scalability expectations, initially projected at 200k requests but ultimately handling over 15 million transactions per second without any issues.
Principal Engineer Manager at a manufacturing company with 501-1,000 employees
As a production engineer at that time, I definitely wanted to ensure that the system could handle massive connections, especially since we operated an e-commerce platform where we could not lose any customer calls.

Featured Reviews

reviewer2797602 - PeerSpot reviewer
Senior Security Systems Engineer at a tech services company with 11-50 employees
Granular security policies have protected critical applications and ensure safe user and admin access
Improvements could be made regarding the log information from the backend CLI. There are enhancements needed; if a request gets blocked on the TCP layer, there should be traces or data to verify which source generated these requests, including the source and port information for initiation. These data are missing from F5 Advanced WAF. Besides that, another improvement could be refining the bot detection to minimize false positives; it should be able to verify more granularly between legitimate and non-legitimate clients. Overall, I find everything else good. A wish list feature I have is for the Technical Assistance Center (TAC) to respond more promptly. Their response time needs improvement; while they do not take excessive time, it can be enhanced, especially given it is a security product.
Shrinivas Devarkonda - PeerSpot reviewer
Head of DevOps at TripFactory
Handles high traffic efficiently and simplifies complex routing with rule-based logic
I think HAProxy is good as it stands now, but I believe there could be improvements. gRPC has recently been implemented, which is great, along with TLS 1.2 and 1.3 support, and HTTP 2.0 is also available. However, I'm unsure about the benchmark of those HTTP 2.0 requests on HAProxy. If there were any other protocol with better performance than HTTP 2.0, or perhaps mTLS and other similar features, including that in HAProxy would be really great. For improvements, I think that during setup and configuration, the steps provided are neat and clear. Anyone can easily install and configure it. There are many kernel tuning parameters also available, which is great. For specific improvement, in terms of logging, I think printing the full object of the request may help, or if there's a way to reference two requests, it would be beneficial to find a complete session history from a logged-in customer, as it would help analyze customer and user analytics.
