Beyond the malware risk, Marcus considered his career. Using a pirated license in a professional environment was a violation of the software end-user license agreement (EULA) and copyright law. If his firm was audited, or if the pirated software "phoned home" to Tenable’s servers (which they aggressively monitor for), he would lose his job and likely face legal action. His reputation in the tight-knit cybersecurity community would be destroyed.

Marcus learned that day: You can't secure a network with stolen goods.

No Compliance Checks

: Unlike the Professional edition , the free version does not support configuration or compliance auditing.
