Tenable

Tenable is a cybersecurity company best known for Nessus and a broader exposure management platform used by vulnerability management teams, security leaders, and operations staff who need to see risk across IT, cloud, identity, web apps, and operational technology. The main site now centers on Tenable One, which pulls asset inventory, exposure analytics, prioritization, and remediation workflows into one platform. That gives the brand a wider role than a single vulnerability scanner, even though Nessus remains the most familiar entry point for many practitioners.

For buyers, the practical distinction is that Tenable serves both mature exposure-management programs and smaller teams that still start with Nessus Professional or Nessus Expert. A consultant can use Nessus for hands-on assessments, while a larger internal team can connect cloud, identity, and application risk into one reporting layer. The company also publishes deep research, plugins, and documentation, so it appeals to technical audiences that care about detection coverage as much as reporting convenience.

Unlike the other four rows in this batch, Tenable does expose a public performance-marketing route. Tenable's own site links to a Tenable Performance Marketing Program on PartnerStack, where partners apply, receive a referral link, and promote Tenable offers such as Nessus Pro and Nessus Expert. The public program directory lists 15% commission on approved orders, link-based attribution with SubIDs, a 90-day cookie, and cash-out through PayPal or Stripe, with rewards calculated at month-end and made available the following month.

Tenable also has a separate official Nessus Professional referral page that is framed as a customer-referral offer and cites 10% on initial purchases for current customers. Because the broader PartnerStack program is linked from Tenable's own site and is the clearer publisher path, it is the primary source used for structured fields here. Publishers should still read the PartnerStack terms before applying, since product scope and approval rules can vary by offer.
