Herb Angle

Owner at Hga consulting

Has helped manage client domains with streamlined access control and threat visibility

I don't know what areas could be improved with Cloudflare WAF; Cloudflare is constantly improving and adding features to their feature set. They're doing a good job, and as far as DNS and support for any domains that I create or my clients create, it's mandatory for me to make sure that they have Cloudflare as their DNS provider. The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service. It doesn't pay to try to host your own website.

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 most valuable feature is its usability."

"What I like best about Cloudflare is that my company can use it to trace and manage applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare also sends you a link to check your equipment and deployment and track it through peering, so it's a valuable tool."

"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."

"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."

"The attacker won't have details since my public IP is anonymous. It offers us good privacy."

"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."

"Generally, I am satisfied with this product."

"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."

More Cloudflare pros

"The most valuable feature of this solution is the simplicity of configuration."

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

"The stability of the solution is good. I don't think we've experienced bugs, crashes, or glitches."

"Even when we were upgrading to a new OS, we didn't have any difficulties with the product. The stability is good."

"The most valuable feature is the automatic content filtering."

"The installation is straightforward."

"This product gives us visibility into what is going on in two servers, including connections and sessions, real-time alerts, very good reporting, and KPIs. It makes managing security of a critical server very easy, with a friendly GUI."

"The most valuable feature is the rule set."

More Barracuda Web Application Firewall pros

"The features I find valuable in this solution are session control which automatically disconnects users that forget to log off, and the ability to write rules to either allow or block certain file requests."

"We were able to use HAProxy for round robin with our databases, or for a centralized TCP connection in one host."

"The technical support has been, in one word, perfect. Every time I call, I’m on the phone with a representative within five minutes who is highly skilled and willing to help, whether in the case of critical issues or simple advice."

"We use it as a load balancer for our application servers."

"The VRRP redundancy is also a mission-critical feature that works seamlessly. I can bring down a server live with minimal downtime because of this."

"I can simplify configurations of many internal services (e.g. Web server configs) by moving some elements (like SSL) to HAProxy. I can also disable additional applications, like Varnish, by moving traffic shaping configurations to HAProxy."

"Performance configuration options with threads, processes, and core stickiness are very valuable."

"The ease of use of the configuration, and great documentation, are the most valuable features for us."

More HAProxy pros

Cons

"It would be beneficial for us if Cloudflare could offer a scrubbing solution. This would involve taking a snapshot of my website and keeping it live during a DDoS attack, ensuring uninterrupted service for our users. DDoS attacks are typically short in duration, and having Cloudflare maintain the site's availability from its secure network would enhance the overall user experience. I would appreciate it if Cloudflare could consider implementing this feature. Many organizations already utilize similar capabilities in their CDN platforms, where a static snapshot of the web page is displayed during DDoS attacks. In terms of features, Cloudflare needs to enhance its resilience and stay more focused on adopting new technologies. For instance, solutions like F5 XC Box, Access Solution, and Distributed Cloud Solution have impressive features, and Cloudflare should strive to match and exceed those capabilities. There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features. Cloudflare should prioritize enhancements in areas such as behavioral DDoS and protection against SQL injection attacks, considering the prevalent trend of public exposure to the internet for business reasons. Overall, Cloudflare needs to invest more in advancing its feature set."

"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."

"The solution could be more user-friendly."

"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."

"Cloudflare could be improved by introducing a mid-tier pricing option."

"The pricing could be improved."

"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."

"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."

More Cloudflare cons

"There's potential for improvement in the platform's CMS integration."

"They could improve their performance, support, and their upgrades. Their updates used to be good. Their improvements were right on the money but nowadays, the updates are minor."

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

"I would suggest that someone implementing this product is knowledgeable in the IT field, and with the network needs. It is complex."

"I would like to see a native multi-cloud cover."

"We encountered a few glitches while implementing API security features into the product."

"The usability of the interface could be improved."

"If you know nothing about networks, then you can't set it up."

More Barracuda Web Application Firewall cons

"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."

"Pricing, monitoring, and reports can be improved."

"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."

"Maybe HAProxy could be more modular."

"I would like to see better search handling, and a user interface, with a complete functional graphical unit"

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

"Dynamic update API. More things should be possible to be configured during runtime."

"We would like to see dynamic ACL and port update support. Our infrastructure relies on randomly allocated ports and this feature would allow us to update without restarting the process."

More HAProxy cons

Pricing and Cost Advice

"The price is reasonable."

"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."

"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."

"The tool is a premium product, so it is very expensive."

"A free version of the solution is available."

"The price of the solution is expensive."

"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."

"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."

More Cloudflare pricing and cost advice

"The pricing is reasonable."

"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."

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

"Cost is a bit on the higher side. Big companies can afford it."

"The price of the solution is a little expensive. There is a license for this solution and it can be purchased every one, two, or five years."

"The product pricing was competitive for the value it offers regarding security features."

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

"They only offer a yearly licensing plan."

More Barracuda Web Application Firewall pricing and cost advice

"We are using HAProxy as an open-source."

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

"Very good value for the money. One of the simplest licensing schemes in this category of products."

"HAProxy is a free open-source solution."

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

"HAProxy is free open-source software."

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

"Test/lab virtual machines can be installed without a licence. They can't be used for performance testing but otherwise behave like production nodes."

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.
