Featured Reviews

Samir Paul - PeerSpot reviewer
Security Practitioner at a tech vendor with 10,001+ employees
Cloud WAF has protected critical web apps and APIs and delivers fast bot and DDoS defense
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 While the interface is functional and centralized, some third-party reviews indicate that the UI can feel outdated, and enhancements are required to provide an executive look that can be aligned with modern and intuitive next-generation competitors.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.
Mohan Janarthanan - PeerSpot reviewer
Associate Vice President at Novac Technology Solutions
Cloud applications have gained stronger protection and real-time defense against web attacks
What really stands out for me in terms of advantages of F5 Silverline Managed Services is that in a single cloud platform, I can protect my web applications against attacks. I can also use my load balancer in F5 because they are providing and acting as a load balancer too, and they will support the volumetric and DDoS attacks and malicious attacks. Regarding the real-time threat intelligence feature, I do use this aspect in F5 Silverline Managed Services. It blocks malicious IPs or bad IPs for my server, protecting against my applications. For example, if someone is a bad actor trying to access via a malicious IP, I can block it because the threat intelligence has the capability to block the malicious IP. The adaptable and flexible security impacts threat response time positively. It is effective because it blocks my malicious traffic. Whenever I face issues related to that application, it automatically routes my traffic to act as a proxy and routes my traffic to their scrubbing center, especially in case of any volumetric attack.
