What switchers say
Paraphrased from verified user reviews of teams that migrated away from Tenable Nessus.
We switched after our team hit the pricing ceiling — the migration took a weekend and we haven't looked back.
— Head of Ops, 40-person SaaS
The UX felt familiar day one, and the CSV importer got us 95% of the way without engineering help.

Same features, roughly a third of the cost. The only thing we lost was one integration we barely used.
