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.

Automated threat detection has reduced staffing needs but dashboard design still needs improvement
Link11 offers high-performing platform capabilities and automated responses. The system operates on its own cloud infrastructure without requiring my input. The automated responses have helped my team and my workflow by reacting to threats in real time and helping mitigate attacks within moments instead of relying on manual alerts and manual response processes. Link11 has positively impacted my organization by helping analyze all incoming traffic continuously, functioning like an employee operating in the background. This background analysis has affected my organization's security and efficiency in that I do not have to worry about it. It operates on the back end automatically, taking care of things that I do not have to worry about or think about, but I know it is working.
