Room For Improvement

KerioControl requires improvements in VPN, user interface, support, security, performance, and customization features for large networks.
SonicWall needs upgraded reporting, intuitive UI, robust NSM, better EDR/XDR, marketing, and firmware fixes to compete effectively.
This would help end-user customers understand the impact when those firmwares are pushed into the live environment.
Head of IT and Information Security at GLEEDS USA INC
The issues I have experienced are not hardware-related but firmware-related, as Gen 7 has new hardware, while the firmware contains some issues that could be resolved but may take considerable time.

Support has resolved concerns promptly and security tools have strengthened intrusion prevention and access control
The service we received from SonicWall NSSP and their distributors has been excellent. Every time I have had a concern, they have resolved it in a single call. The interface of SonicWall NSSP console is user-friendly with comprehensive features. The web filtering and access control policy are top priorities for me. It is very effective because it prevents any indecent behaviors in the network or from outside the network. Half of the task is completed by the intelligence based on the behavior. Installation was easy because our infrastructure has minimal requirements. For expanded infrastructure, support from a SonicWall NSSP technical team may be required. We have implemented it on our own.
