For organizations requiring offline activation—such as those in air-gapped environments—Tenable provides special offline license packages.

Tenable will then send an offline activation package containing license files and installation guidance.
Activation codes are case-sensitive. Re-enter the code carefully, and consider copying and pasting directly from your purchase confirmation email. Step-by-Step Activation Guide Are you setting up Nessus
As of the last published pricing, a Nessus Professional license typically costs around $3,000 to $4,000 USD per year per scanner. While this is significant for an individual, it is standard for enterprise-grade security tools.
Consider the math: a Nessus Professional license costs approximately $2,400–$2,990 per year. For a small business with 20 servers and 100 workstations, that's roughly $8–$10 per asset per year for continuous vulnerability scanning. The cost of a single data breach averages in the millions of dollars. The math makes a powerful case for legitimate licensing. As one expert put it, "省小钱反酿大损失" (trying to save small amounts of money leads to huge losses).
