Overview
The Barracuda CloudGen WAF detects all inbound web traffic and blocks SQL injections, cross-site scripting, malware uploads, volumetric & application DDoS, or any other attacks against your web applications. It also inspects the HTTP responses from the configured back-end servers for data loss prevention (DLP). The integrated access control engine enables administrators to create granular access control policies for Authentication, Authorization & Accounting (AAA), which gives organizations strong authentication and user control. The onboard L4/L7 load balancing capabilities enable organizations to quickly add back-end servers to scale deployments as they grow. Its application acceleration capabilities, including SSL offloading, caching, compression, and connection pooling, ensure faster application delivery of web application content. The Barracuda CloudGen WAF also supports autoscaling and bootstrapping.
NOTE: Only AMIs with version 10.x or higher version support the Elastic Network Adapters (ENA).

Cloud WAF has protected critical web apps and APIs and delivers fast bot and DDoS defense
What is our primary use case?
My main use case for Barracuda WAF-as-a-Service is protecting web applications running on HTTP and HTTPS sockets from OWASP Top 10 attacks, malicious bots, account takeover attempts, and L3 to L7 DDoS attacks.
Barracuda WAF-as-a-Service is a cloud-delivered web application firewall designed to protect web applications and APIs from threats such as OWASP Top 10 attacks, malicious bots, account takeover attempts, and L3 to L7 DDoS attacks. It is positioned as a fast to deploy and manage WAF service with pre-built templates, centralized policy control, API protection, and automation support through REST APIs. Barracuda WAF-as-a-Service is a cloud WAF that helps protect websites and APIs quickly without the overhead of deploying and managing traditional web appliances.
What is most valuable?
Barracuda WAF-as-a-Service offers several best features including a cloud-delivered WAF for web apps and APIs, fast setup via deployment wizard and templates, protection against OWASP Top 10 and zero-day style web threats, API security for REST, JSON, and GraphQL APIs including discovery and exposure of shadow APIs, bot protection, unmetered L3 and L7 DDoS protection, automation support, and compliance visibility and reporting.
I find API security, web app and API security, and bot protection to be the most valuable day-to-day features of Barracuda WAF-as-a-Service. Using Barracuda is very easy and fast due to the fast deployment wizard, allowing deployment based on wizards or templates. Onboarding applications is very easy with a turnaround time of only one or two days. API security covers all API types, starting with REST, JSON, and GraphQL APIs. Bot protection includes malicious learning backend for malicious bots, credential stuffing, brute force, and account takeover defense.
Barracuda WAF-as-a-Service has impacted my organization positively with fast deployment and simple onboarding. One of the strongest points is the speed of deployment, which features a three-step deployment wizard, pre-built templates, and quick onboarding, making it suitable for teams that want protection fast without complex infrastructure setup. For example, if a business wants to protect a customer portal or public website quickly, Barracuda can be onboarded in a minute using pre-defined templates instead of spending days tuning an appliance.
Another strength is strong API and application protection. Barracuda WAF-as-a-Service protects both traditional web applications and modern APIs, including REST, JSON, and GraphQL, and it supports API discovery to identify exposed shadow and zombie APIs. Bot and account takeover protection is included along with DDoS protection which adds application level DDoS that protects L3 to L7 type of DDoS threats like HTTP flood. There is a good balance of simplicity and control.
I notice faster time to detection because since the onboarding uses a wizard and template, the organization can reduce deployment effort by 30 to 50% faster deployment effort for standard web app onboarding. There is lower operational overhead since the solution is delivered as a service, allowing customers to avoid appliance lifecycle management and benefit from automated updates and managed service characteristics. From an ROI and impact perspective, there is a 20 to 35% reduction in day-to-day administrative effort. Additionally, there is reduced business impact from downtime because built-in L3 to L7 DDoS protection and application layer security can reduce outage risk and service disruption for customer-facing applications.
What needs improvement?
Regarding improvements for Barracuda WAF-as-a-Service, the UI and user experience can feel dated. While the interface is functional and centralized, some third-party reviews indicate that the UI can feel outdated, and enhancements are required to provide an executive look that can be aligned with modern and intuitive next-generation competitors.
The licensing and cost structure perspective may need clear planning. Barracuda service is customizable but external references note that licensing and cost planning can become complex.
Advanced analytics and executive reporting could be better. The platform provides visibility and compliance reporting but organizations looking for a very polished executive dashboard, deep attack visualization, or broader cloud-native security context may find it more focused on WAF operation.
Barracuda WAF-as-a-Service is best suited for app and API protection and is not a full CNAPP platform. It is strong for application layer protection but is not positioned as a full CNAPP covering posture management. Modernizing the UI further, simplifying packaging and licensing clarity, enhancing the executive reporting and risk dashboard, and expanding broader cloud-native integration would be beneficial improvements.
For how long have I used the solution?
I have been using Barracuda WAF-as-a-Service for almost eight years.
What do I think about the stability of the solution?
I do not see any latency with Barracuda WAF-as-a-Service. It is a software as a service, so the provider maintains all the infrastructure and it is very scalable, so I do not see any challenge.
Barracuda WAF-as-a-Service is extremely accurate in detection and reporting, and I find very few false positives. When deploying this solution, you have to take care of a few things very cautiously, especially understanding how the application works and defining the policy carefully. Otherwise, it could bring false positive alert fatigue. Alert fatigue depends on who is implementing the solution. If experienced and expert people with Barracuda implement the solution, you will get less alert fatigue.
What do I think about the scalability of the solution?
Barracuda WAF-as-a-Service can handle increases in traffic or new applications easily since this particular solution is built for that specific purpose.
How are customer service and support?
Barracuda WAF-as-a-Service provides good support and the support team is very cooperative and helpful.
Which solution did I use previously and why did I switch?
I purchased Barracuda WAF-as-a-Service via a partner and not through the AWS Marketplace .
How was the initial setup?
Barracuda WAF-as-a-Service is a cloud-delivered web application firewall designed to protect web applications and APIs from threats such as OWASP Top 10 attacks, malicious bots, account takeover attempts, and L3 to L7 DDoS attacks. It is positioned as a fast to deploy and manage WAF service with pre-built templates, centralized policy control, API protection, and automation support through REST APIs. Barracuda WAF-as-a-Service is a cloud WAF that helps protect websites and APIs quickly without the overhead of deploying and managing traditional web appliances.
What about the implementation team?
I maintain all the governance and security for Barracuda WAF-as-a-Service as per the standard. Each organization has certain compliance requirements that they need to adhere to, and these are already in place with Barracuda. I fully agree with the policy mapping that is shown when designing the WAF policy and it is very much in line with compliance strategy.
What was our ROI?
Since the solution is delivered as a service, customers avoid appliance lifecycle management and benefit from automated updates and managed service characteristics. From an ROI and impact perspective, there is a 20 to 35% reduction in day-to-day administrative effort. Additionally, built-in L3 to L7 DDoS protection and application layer security can reduce outage risk and service disruption for customer-facing applications.
What's my experience with pricing, setup cost, and licensing?
The licensing and cost structure perspective may need clear planning. Barracuda service is customizable but external references note that licensing and cost planning can become complex.
Which other solutions did I evaluate?
If organizations have any public-facing application, they should use WAF-as-a-Service and Barracuda is a good choice, but there are other choices as well. When choosing any solution, you have to check other aspects such as the people aspect, people, process, and technology. These three have to be consolidated. If any organization needs suggestions, they could reach out to me for help in choosing the right solution.
What other advice do I have?
Barracuda WAF-as-a-Service is best suited for app and API protection and is not a full CNAPP platform. It is strong for application layer protection but is not positioned as a full CNAPP covering posture management. Modernizing the UI further, simplifying packaging and licensing clarity, enhancing the executive reporting and risk dashboard, and expanding broader cloud-native integration would be beneficial. I would rate my overall experience with this solution as an eight.
Which deployment model are you using for this solution?
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Enterprise-Level Firewall at a Great Value, with Unmatched Barracuda Support
Impressive Automation and Easy Cloud Integration with Deep Threat Protection
Advanced threat analytics have strengthened compliance efforts but licensing and SIEM need work
What is our primary use case?
I deal with Barracuda WAF-as-a-Service and usually recommend it for private and government companies.
What is most valuable?
The automatic security updates are excellent. These updates help our customers transition smoothly between interface versions. We started with an old Barracuda interface, implemented everything there, and then moved to the new interface, which is very good and helpful.
Barracuda WAF-as-a-Service 's real-time attack detection feature has improved our customers' threat response strategies significantly.
I have found value in the actionable analytics provided. Our customers have seen benefits such as access to a lot of data and the ability to analyze real-time threats through the actionable analytics.
What needs improvement?
I assess the impact of Barracuda WAF-as-a-Service on compliance efforts regarding security events as good in terms of compliance, although there are a few issues. There is one issue regarding local data storage, as they do not have that capability, and we are storing the data in another foreign country, which is against the law. Data is supposed to be within the South African border.
In my opinion, the main direction for improvement should be around the licensing part, as it should not be quite complex. The price of their licensing model is a bit steep. However, for other features such as web application threat detection and data compliance, they are very good, especially for application trafficking and caching. The pricing and SIEM integration sometimes create challenges, and we need to get professional help with those areas.
For the next release, Barracuda WAF-as-a-Service should include advanced APIs and perhaps AI-driven detections. They can improve the integration with SIEM and SOAR .
For how long have I used the solution?
I have been working with Barracuda WAF-as-a-Service for quite a few years.
Which other solutions did I evaluate?
There are competitors to Barracuda WAF-as-a-Service. Depending on a client's requirement, I would recommend it, but there are competitors such as F5 and Cloudflare , and it depends on what the client wants. Sometimes, clients might want a firewall and choose something like Fortinet or Cisco secure firewall.
What other advice do I have?
The price of their licensing model is a bit steep, but for other features such as web application threat detection and data compliance, they are very good, especially for application trafficking and caching. I am happy with it; it is just that the pricing and SIEM integration sometimes create challenges, and we need to get professional help with those areas.
Implementing Barracuda WAF-as-a-Service is quite complex, and you need to have substantial knowledge in this area. I rate Barracuda WAF-as-a-Service an overall score of six.
