The Verdict
Microsoft Azure is built for enterprises and microsoft shops, with a focus on virtual-machines and azure-functions. Tenable targets security teams and compliance officers and leads with vulnerability-scanning and asset-discovery.

Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Microsoft Azure offers broader built-in capabilities (7 features vs 6), while Tenable takes a more focused approach — which can mean a simpler, faster onboarding experience.
