Featured Reviews

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.

Exceptional resilience and protection well-suited for medium to large businesses
The initial setup process is quite straightforward. Its complexity largely depends on the intricacies of your platform. If your platform spans multiple sites across the globe, requiring configuration of multiple instances and traffic routing, it can become more intricate. From our experience, even in companies with extensive platforms, the configuration process remains relatively simple. Once the instances are spun up and the initial configurations are in place, you can use their console application to set up your site or sites for traffic management. This involves configuring the sites and uploading SSL certificates. Even for those not well-versed in the intricacies of networking layers and rules, the out-of-the-box configurations already provide solid protection.
