Advanced security reporting has protected high-traffic betting platforms from constant attacks

I don't see room for improvement to Cloudflare Web Application Firewall. One thing I don't know much about because we have a dedicated IT team for that, and I'm not involved with Cloudflare much anymore. But if I were to compare them to F5, I would like to see more features that F5 offers. F5 has an option to bring the whole infrastructure, the whole WAF and all their packages, Bot Management, and everything else on your infrastructure. You need to install certain services from their side, and then you can choose if you would like requests to hit your servers immediately or if requests need to be proxied through F5 backbone. That would be a nice addition because we have 90% of the traffic as legit traffic coming from whitelisted servers. If it comes from whitelisted servers, I don't need to go every request through the backbone; I could easily just IP whitelist everything. Then I could maybe have Bot Management on my infrastructure that drastically reduces the price of Cloudflare. I would like to see Push CDN more improved in the next release of Cloudflare Web Application Firewall. And maybe something similar to Pushpin that Fastly has, which is an option where you can push messages that then can be scaled globally over the network. From our perspective, if we have a listener that listens for stock updates, I would just need to have one processor that pushes those updates to the Cloudflare API, and then Cloudflare would broadcast that message to all listeners. Cloudflare will check the order of the message, and if you, as a customer, are not connected or have some kind of network issue, when you reconnect, you will receive the latest state and missing updates.

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.

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.

Quotes from Members

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

Pros

"The Cloudflare Web Application Firewall's most valuable feature is its ease of configuration."

"Cloudflare WAF provides protection through rules and functionalities like Cloudflare's SDRAP."

More Cloudflare Web Application Firewall pros

"We run it with no downtime, because it has good support."

"Since implementing Barracuda, I sleep smoothly knowing I have protection."

"You don't need help from Barracuda to help with the deployment. The deployment is easy."

"What I like most about Barracuda Web Application Firewall is its availability. I also like that it's an easy-to-use solution."

"The most valuable features of Barracuda Web Application Firewall include advanced bot protection, DDoS protection, and addressing the top ten vulnerabilities."

"The updating and signature features are my primary use case for the solution. These features are beneficial to my organization."

"The solution ensures layer seven is secure from attacks."

More Barracuda Web Application Firewall pros

"Tech support is super-quick to respond, and always on target with answers specific to the current issue."

"Advanced traffic rules, including stick tables and ACLs, which allow me to shape traffic while it's load balanced."

"Stability is number one."

"The support for all major Linux distros makes running and testing a breeze."

"With centralized SSL termination and automated renewals now in place, that time requirement has dropped to nearly zero hours, translating to dozens of hours saved per year."

"It is a crucial tool in ensuring smooth service provision without any interruptions."

"We achieved 100% money savings and fewer employees with very little maintenance required."

"We definitely saw fewer employees needed and money saved; we achieved 100% money savings and fewer employees with very little maintenance required."

More HAProxy pros

Cons

"The blocked logs are difficult to read at times."

"Support can be challenging at times."

"Cloudflare Web Application Firewall should improve visibility for a customer."

"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."

"The platform's control features related to real-time authentication and response time need improvement."

"The ModSecurity core rules need to be updated."

"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."

"The dashboard could be more user-friendly."

More Cloudflare Web Application Firewall cons

"I would like to see better controlling of the traffic."

"An area for improvement in Barracuda Web Application Firewall is attack identification. Other banks identified attacks and tracked logs that the solution wasn't able to identify because of its ready-made rules pre-deployed by the vendor. My organization raised this issue with the technical support team. Another area to improve in Barracuda Web Application Firewall is its service desk. The team resorted to stonewalling because they couldn't accept that a feature was missing in the solution, and it was only after a lot of drilling down that the service desk team accepted that, and would be adding that feature in the future. My organization had to submit a report to the Reserve Bank of India with information on the logs identified and the attacks that happened, and that there was a failure on the part of the Barracuda Web Application Firewall. The Reserve Bank of India conducts a tri-monthly cyber risk audit in all Indian banks. Even smaller banks identified and caught attacks that my organization wasn't able to do, so I was looking into other solutions that competitor banks could be using because Barracuda Web Application Firewall failed to identify some of the attacks."

"Barracuda Web Application Firewall’s scalability needs improvement."

"They should improve their features, so they easily compare to the competition."

"I faced an issue when Barracuda decided not to support Azure Stack Hub anymore, which was a significant issue as we had many customers using it on that platform."

"Barracuda Web Application Firewall's load balancing feature could be improved."

"It is not stable nor mature."

"The policy updates could be improved."

More Barracuda Web Application Firewall cons

"HAProxy could improve by making the dashboards easier to use, and better reports and administration tickets."

"Documentation could be improved."

"The logging functionality could use improvement, as it is a little cryptic."

"Sometimes it's challenging to get through the log, and you need a log to understand what is going on. It isn't easy to map the logging with the documentation, and every time I read the log, I have to pull out the documentation to understand what I'm reading."

"I would like to evaluate load-balancing algorithms other than round robin and SSL offloading. Also, it would be helpful if I could logically divide the HAProxy load-balancing into multiple entities so that I would install one HA Proxy LB application which could be used for different Web servers for different applications. I am not sure if these features are available."

"There are three main areas to improve: 1) Make remote management more modern by adding API. 2) Propose a general HA solution for HAProxy (no I'm using keepalived for this). 3) Thread option should be a bit more stable."

"There is no standardized document available. So, any individual has to work from scratch to work it out. If some standard deployment details are available, it would be helpful for people while deploying it. There should be more documentation on the standard deployment."

"If nbproc = 2, you will have two processes of HAProxy running. However, the stats of HAProxy will not be aggregated, meaning you don't really know the collective status in a single point of view."

More HAProxy cons

Pricing and Cost Advice

"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."

"The solution's pricing option needs to be more transparent for enterprise clients."

"We pay $210 per month for CloudFlare WAF."

"What's my experience with pricing, setup cost, and licensing? I believe the pricing is not the best, but it's reasonable and acceptable. We also use the McAfee system in parallel. In terms of pricing, its okay - not great, but not bad either. It falls in the middle, which is acceptable. In terms of support licensing, last time, we were searching for a solution, and we considered products from resellers rather than directly from the cloud provider. However, the pricing we encountered was exceptionally high. As a result, we are inclined to select support from the reseller."

"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."

"The annual licensing fee is $10,000 USD."

"The solution is expensive."

"It starts at $20 and can easily go up to $200 monthly"

More Cloudflare Web Application Firewall pricing and cost advice

"For small companies, the price is very expensive because the WAF is an enterprise-level application, not intended for smaller businesses. In my opinion, the price is right for enterprise-level use."

"They have competitive pricing."

"Our licensing fees are paid annually and the cost is between €600 and €800 (approximately $665.00 to $885.00 USD)."

"The pricing is less compared to other web applications."

"Barracuda costs us $8,000 per year. Barracuda costs $20,000 for a full subscription, when you try to protect multi-site infrastructure, in different geographical zones and for different data centers. If you have only one site, Barracuda will be cheaper."

"The price of this solution is okay."

"While I would have to check on the price of the solution, I feel it to be okay and it matches the market price."

"In my opinion, the product is fairly priced."

More Barracuda Web Application Firewall pricing and cost advice

"The licensing fee for the solution is $690 per unit annually."

"When it comes to pricing HAProxy is free."

"The only cost is for the image manager, who is responsible for uploading the image, and that is trivial."

"I think that the pricing is very fair, I would definitely recommend buying the Enterprise license."

"If you don't have expertise then go with the licensed version. Otherwise, open-source is the best solution."

"HAProxy is a free open-source solution."

"HAProxy is free software. There are optional paid products (support/appliances)."

"We use NGINX as well. However, because the health checks are a paid feature, I like to avoid it whenever possible."

Overview

Cloudflare Web Application Firewall's intuitive dashboard enables users to build powerful rules through easy clicks and also provides Terraform integration. Every request to the WAF is inspected against the rule engine and the threat intelligence curated from protecting over 27 Million websites. Suspicious requests can be blocked, challenged or logged as per the needs of the user while legitimate requests are routed to the destination, agnostic of whether it lives on-premise or in the cloud. Analytics and Cloudflare Logs enable visibility into actionable metrics for the user.

Cloudflare

Barracuda Web Application Firewall is a game-changing cloud-connected security solution that enables organizations to safeguard both their applications and their data from an ever-growing array of advanced cyber threats. It offers protection from cyber attacks that target not only data and applications stored on the cloud but also those that are housed on web servers. 43% of the time a breach takes place via a compromised application. Barracuda Web Application Firewall prevents these types of breaches from occurring.

Barracuda Web Application Firewall denies hackers the ability to penetrate your system by using a number of techniques to keep your organization safely insulated. The first method of protection consists of two parts. The first part involves a thorough scanning of all inbound web traffic. This solution monitors everything that comes into the system. It employs IP reputation intelligence, which filters all incoming data. If the source of the data has a bad reputation, it is blocked by the firewall. Administrators now have a way of locking out many common threats that could otherwise compromise sensitive networks. These scans can also allow administrators to protect their systems from within as DLP (Data Loss Prevention) protocols. If any sensitive data attempts to leave, administrators will automatically be alerted and the data will be blocked from exiting.

Barracuda Web Application Firewall can also be set up to apply the AAA (Authentication, Authorization & Accounting) framework to an organization’s network. If an intruder manages to get past the authentication stage, the authorization protocols kick in. After the authorization stage comes accounting, which works by tracking and logging users’ activities so that administrators will be in a position to prevent long-term damage from being done. This three-step process can be implemented without requiring administrators to make changes to their applications.

Key Features

Some of Barracuda Web Application Firewall’s key features include:

The ability to employ adaptive profiling. Administrators will have an easier time enforcing security policies once this feature is enabled. It takes data from safe sources and builds profiles that can be used to create whitelisting protocols that prevent unsafe actions from occurring on the system.
The ability to assess threats in real time. Barracuda Web Application Firewall uses machine learning to detect new threats and attacks as they emerge.
The ability to manage the Barracuda Web Application Firewall system from a single interface. Administrators can manage their Barracuda Web Application Firewall configurations from one centralized location.

Reviews from Real Users

Barracuda Web Application Firewall stands out among its competitors for a number of reasons. One of the main ones is the robustness of the solution. Users are given access to a vast variety of security features in a single product.

PeerSpot user Muhammed S., a Presales Solutions Architect at Hilal Computers, notes this when he writes, "The solution offers multiple security features. There are machine learning features and great URL encryption. It also offers multi-protocol support against DDoS attacks."

Other reviewers note that Barracuda Web Application Firewall is user-friendly, easy to set up, stable, and reliable.

Reviews from Real Users

“Having the right load balancing solution – which is what HAProxy is – and protection in place gives organizations peace of mind.” - Nathanel S., Platform Architect at SES

“I use HAProxy for individuals who can not buy low balancers. I built NFV in a box and send individuals a pathway into an HAProxy VM. The setup was not difficult; it usually takes a day to complete for a VPC. When it comes to pricing, HAProxy is free.” - Nasir O., Network & Cloud Architect at Koala Compute Inc.
