Tenable

Their marketing strategy seems strong, particularly the notion of "Cyber Exposure". They have a broad reach across many market sectors to sell into.

All scanner products are based on a common codebase that's 25 years old. The code is the worst I've seen. All code is written in Tenable's proprietary NASL language, similar to but much less flexible than C, making development work an extremely dreary endeavor. The code is an unstructured conglomeration of features cobbled together over decades. No engineers I worked with understood how the features worked, and there was limited documentation.

The technical leadership decided to kill most of the QA organization, so developers do all testing manually. It's the biggest circus I've seen; we took the kids to Ringling Brothers.

Upper management does not seem competent, especially technical leadership.

The culture is silly, with peppy slogans from HR painted all over the walls, which the organization does not actually follow.
