Dns architect at a outsourcing company with 5,001-10,000 employees
Robust protection has secured global web assets and keeps critical applications available
F5 Silverline Managed Services can be improved in areas with complex onboarding processes and slow deployment settings. Tuning of policy requires significant technical expertise, and there is a lack of knowledge in the F5 world where one needs to go through a steep learning curve in understanding what and how the policy should be configured for effectively protecting an application. These processes need to be streamlined.Knowing the limitations of F5 Silverline Managed Services, F5 has come out with a new product called F5 distributed cloud WAF platform, which has a better API integrated with security modules. It also offers advanced auto discovery, swagger, and open API validation, which is much better than Silverline.

Load balancing and secure access have supported complex migrations and automation at scale
NetScaler has positively impacted my organization because I work for a system integrator and deploy it for customers. Many customers are really happy with NetScaler, except for the pricing, as Citrix has changed a lot of their pricing in the last two or three years when they transitioned to Cloud Software Group. However, despite that, I know customers are really satisfied with the technical capabilities that NetScaler provides. While I do not have specific outcomes or metrics from my customers, I think using Core Logic has made it much easier for the big municipality I mentioned to implement NetScaler as a total solution, thus speeding up their automation. There are likely many benefits, but I lack benchmarks or timing figures to quantify that.
