The Activation Code cannot be shared between scanners.

Once the Activation Code has been registered, it cannot be returned. Product cannot be returned after 30 days from purchase date. If you return the product prior to registration within 30 days, there will be a transaction fee. Please contact us at purchases@tenable.com to determine the fee.
