ROI

Sentiment score
5.8
Barracuda Web Application Firewall provides positive ROI, enhanced security, reduced manual efforts, and peace of mind against attacks.
Sentiment score
7.2
HAProxy boosts efficiency by reducing costs and staff needs, offering speed, reliability, and enhanced scalability for traffic management.
My development team is working on the latest language tools or applications, so until then, this web application firewall is essential in my network to protect my existing online assets or software.
Director Information Technology at College of Physicians & Surgeons Pakistan
We have seen a return on investment as the manual work for monitoring attacks and generating reports is reduced significantly, saving money.
Senior Security Systems Engineer at a tech services company with 11-50 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%.
Head of DevOps at TripFactory
I estimate seeing a return on investment with HAProxy, as it significantly reduced staff requirements and enhanced scaling capabilities, particularly when transitioning from NGINX, which faced issues.
Principal Engineer Manager at a manufacturing company with 501-1,000 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

Barracuda Web Application Firewall needs UI updates, better integration, enhanced features, and improved support for multi-cloud environments.
Users recommend improved HAProxy documentation, management tools, dynamic configuration, cloud integration, APIs, and enhanced load-balancing and clustering capabilities.
Reducing false positives must be a priority.
Director Information Technology at College of Physicians & Surgeons Pakistan
The issues with false positives affect client transactions, leading to complaints about blocked transactions.
Technical Lead at cmsit services
Tenable provides more comprehensive dark web scanning capabilities, which Barracuda could improve upon.
Cyber Security Consultant at Axle iT
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

Barracuda Web Application Firewall offers competitive pricing for enterprises, though potentially pricey for smaller businesses; negotiation can assist.
Enterprise buyers find HAProxy cost-effective, with free open-source options and a pricier Enterprise Edition offering enhanced features.
I requested a quote from Barracuda's UK team, which was half the price I was quoted in Pakistan.
Director Information Technology at College of Physicians & Surgeons Pakistan
The pricing for Barracuda is quite high compared to other OEMs.
Technical Lead at cmsit services
They are competitive when compared to other vendors including F5 and Imperva, who tend to have higher prices.
Senior Security Systems Engineer at a tech services company with 11-50 employees
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.

The most valuable feature of Barracuda Web Application Firewall is managing bot traffic.

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

Shahzad Abid - PeerSpot reviewer
Director Information Technology at College of Physicians & Surgeons Pakistan
Has protected our legacy applications effectively but has required constant manual filtering due to false positives
I assess the effectiveness of the machine learning-driven threat detection in Barracuda Web Application Firewall as sometimes behaving abnormally, often showing me false positive attacks, so I have to fix these attacks from time to time. From a stability point of view, I would definitely rate Barracuda Web Application Firewall a seven out of ten. There is definitely some room for improvement; nothing is perfect in the world. I am not satisfied with the technical support from Barracuda. I am somewhat disappointed with the technical support that I have received so far. Whenever I generate a ticket for my problem, it goes to the Indian support team, and they all the time start with the most junior team member, consuming all my precious time. At the end, I have to close that ticket without any satisfactory solution. I have complained that they should shift my support to any other region because I don't need Indian support; they are simply pathetic and not up to mark. To improve Barracuda Web Application Firewall, customers should be given ongoing training opportunities regarding the product and its features. I am not familiar with many features that are available, only using those which are necessary for my applications. I believe Barracuda must provide clearer product information or training sessions to make it more user-friendly, as sometimes its interface can be rigid and lacking in helpful resources or user tutorials about its features. For it to get closer to a ten, I think advanced reporting is missing because, as I mentioned earlier, there are many false positive events being recorded. Often, when I analyze these attacks, they turn out to be genuine customers or users interacting with my product, but Barracuda tags them as attackers. Reducing false positives must be a priority.
Shrinivas Devarkonda - PeerSpot reviewer

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.
