The Verdict
Grafana is built for devops teams and sre teams, with a focus on dashboards and data-sources. Tenable targets security teams and compliance officers and leads with vulnerability-scanning and asset-discovery.
On pricing, Grafana is the clear winner for budget-conscious users — starting at $29/mo compared to $3990/mo for Tenable. That $3961/mo difference adds up quickly for growing teams.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Grafana offers broader built-in capabilities (8 features vs 6), while Tenable takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: Grafana has a slight overall edge — but if comprehensive vulnerability coverage matters most to you, Tenable may still be the right call.
