Room For Improvement

Cloudflare WAF needs feature enhancements, better usability, improved support, advanced DDoS protection, and solutions for latency and alerts.

Dean Barisic

CTO at PlayNirvana

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.

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.
