When a new communication technology or product is being developed, hardware and software engineers rely heavily on protocol analyzers, also known as sniffers or bus analyzers to identify problems and speed the development process.

Frontline provides PC-based protocol analyzers for developers and industrial applications.

In the past 25 years, Frontline has released several protocol analyzers.
