One feature that works really well is the SSL VPN. It's very easy to set up and you can go very granular with it. You can define what user groups get what kind of access and the management overhead is very low.
NetScaler enhances security with SSL offloading and offers features like load balancing and SSL VPN for efficient management. It provides high availability and performance while supporting scalability. However, documentation and support are limited, and the pricing is opaque. Configuration is complex, and security improvements are necessary. Frequent firmware upgrades disrupt stability. Despite these challenges, NetScaler is a comprehensive solution for enterprises.
