Building secure, scalable networks with Grandstream GWN7800 Pro

Posted by Daniel Noworatzky on Jan 28, 2026 11:29:53 AM

January 28 marks Data Privacy Day, an international effort to raise awareness and promote best practices around privacy and data protection. While these conversations often focus on policies, compliance frameworks, and software controls, data privacy also depends on something more fundamental: how traffic moves through the network itself. That’s where the access layer plays a critical role. With the launch of its newest Pro Series layer 2 switches, Grandstream is giving small and mid-sized businesses the tools to build scalable, secure, high-performance enterprise networks that are fully manageable and customizable.

In this article, we examine the first four switches introduced in the new series, highlighting their most noteworthy features and sharing our perspective on key use cases and capabilities.
