Security management has reduced ransomware risk and now protects cloud workloads efficiently
The best features that Barracuda WAF-as-a-Service offers are an intuitive centralized dashboard, allowing us to manage policies, Internet protocol servers, antiviruses, anti-DDoS attacks, and traffic shaping across multiple sites. This feature enables seamless scaling of our environments, especially as we work within Amazon Web Services. Additionally, real-time threat intelligence helps us to detect threats in real-time. Another major feature I love is application control and VPN support, providing granular visibility and protection without needing separate appliances. The centralized dashboard is helping us streamline visibility across our admin panels and provides site-to-site visibility deployed directly to our AWS environment, securing VPC traffic and ensuring the firewall is in place. The real-time threat intelligence is an advanced feature helping us track real-time attacks, such as anti-DDoS attacks, ransomware, or viruses that can compromise system integrity. Through the intuitive centralized dashboard, we can manage policies and set rules, assisting us effectively.

Mutual TLS has secured our web services and now needs broader protocol support
The most valuable feature we have found in Microsoft Azure Application Gateway is mutual TLS. We find mutual TLS valuable because we can verify the client securely by setting up the trust certificate of the client, and also if we do it at the client side as well. This successfully develops mutual trust, ensuring that we know the client who is calling our service is a legitimate client. That is a very nice feature.Microsoft Azure Application Gateway has helped manage our traffic efficiently because we have many web services that we can put behind the same URL, and we can have different URLs with the same Application Gateway with a limited number of listeners. We can do host-based routing as well as URL-based routing or path-based routing. It supports both, so we can have even a single URL supporting many applications, or we can have different URLs for different applications respectively. We have both use cases.

Quotes from Members

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

Pros

"It provides an ease of policy management."
"The most valuable features of the solution are it is plug and play, has automated policies, a simple configuration, and is easy to create rules."
"Barracuda WAF-as-a-Service has positively impacted our organization by reducing cyber threats like ransomware and phishing by ninety-five percent."
"I like its ability to identify known attacks, including DDOS attacks. It's valuable because software must be able to stop known attacks. Application attacks are evolving all the time. When it comes to software-as-a-service, we need to have software that knows about all the latest attacks. It should also protect against major unknown attacks."
"The product's bot protection feature is valuable for our company."
"The solution can be used for threat prevention or as a cloud-to-cloud backup system"
"The most valuable feature is WAF."
"We use the product in front-end and back-end applications to do the load balancing smartly."
"Application Gateway automatically redirects unwanted users and takes care of the security aspect. It also handles the performance side of things, which is why we use it."
"The solution provides great automation and it is easy to upgrade service."
"WAF feature replicates the firewall."
"I find Application Gateway’s WAF module valuable because it helps prevent layer 7 attacks."
"I believe it is up to the mark, as Microsoft security is bulletproof."
"Microsoft has a vast variety of tools, and it blends very well."
 

Cons

"It's a very specific solution that is only requested for a customer's web code or their global IT policy."
"We found it a bit slow when accessing it through the web browser. The URL also exposed the user name and the hashed password. When I log into my Barracuda WAF user portal, I could see the username and the hashed password on the URL itself. So, it is not very secure, and it is important to take that off."
"The stability of the product is an area of concern where improvements are required."
"The solution can improve by bundling Security Operation Center (SOC) with the WAF-as-a-Service, it would provide a lot more value to customers."
"One significant area for improvement in Barracuda WAF-as-a-Service lies in its market positioning and pricing strategy."
"It could be more stable, and support could be better. It would also be better if they offered more features. For example, it lacks security features. Before we used another English solution, and we realized that some of the rules were not set up correctly and passed through the Application Gateway's English controllers. But the problem, in this case, is if you send ten rules, for example, six rules hit some issues. IP address blocking could be better. The rules, for example, don't work properly. If you have one issue, one rule or another rule will not work. This sounds like total madness to me."
"The solution needs improvements in integrating different services and creating a better application balance."
"The solution could improve by increasing the performance when doing updates. For example, if I change the certificate it can take 30 minutes. Other vendors do not have this type of problem."
"Application Gateway’s limitation is that the private and the public endpoint cannot use the same port."
"The working speed of the solution needs improvement."
"I want the solution's support to improve. The tool is also expensive."
"Needs easier integration with the existing SIAM."
"The pricing of the solution is a bit high. The solution should offer different pricing systems."
 

Pricing and Cost Advice

"I rate the product's price a five on a scale of one to ten, where one is low, and ten is high. There are no additional costs to be paid apart from the standard licensing fees attached to the solution."
"It's very difficult for me to give an estimate of the cost. All I know is that we sell the box itself as a service."
"The product is expensive but it offers flexible pricing. It could be affordable."
"The solution is paid monthly. The solution is highly expensive."
"The cost is not an issue."
"The product is not expensive."
"It is an expensive solution. We have an enterprise agreement, it is monthly."
"The solution is fairly priced."
"Microsoft Azure Application Gateway is expensive."
"The solution is cheaper than Imperva. I rate it four to five out of ten."
"The solution is reasonably priced compared to other solutions."
