Impact organizations increasingly hold sensitive beneficiary data, donor records, and program information across cloud systems, web applications, and internal networks. A single unpatched vulnerability can expose that data. Tenable gives security and IT teams visibility into where those exposures sit before an attacker finds them first.
What Tenable does
Tenable is a cybersecurity exposure management platform covering vulnerability management, web application security, cloud workload protection, and attack surface management. Its Tenable One platform brings these into a single view of risk across an organization’s assets, while standalone products like Nessus focus specifically on vulnerability scanning.
Key features
- Vulnerability management: continuously scan networks, endpoints, and applications for known security weaknesses.
- Attack surface management: discover assets and exposures across your organization, including ones you may not know exist.
- Cloud workload protection: extend visibility into cloud infrastructure alongside traditional on-premises systems.
- Attack path analysis: understand how an attacker could chain together exposures to reach critical assets.
- Risk scoring: prioritize which vulnerabilities to fix first based on actual exploitability and business impact.
- Nessus scanning: Tenable’s standalone vulnerability scanner, available separately from the full Tenable One platform.
Pricing
Tenable One packages are quote-based, while standalone products publish list pricing directly.
| Product | Price | Notes |
|---|---|---|
| Tenable One Foundation / Advanced | Custom quote | Full exposure management platform, priced by asset count |
| Vulnerability Management (100 assets) | $3,500/year | Includes web app scanning |
| Web App Scanning (5 FQDNs) | $3,578/year | Standalone web application scanning |
| Nessus Professional | $4,790/year | Standalone vulnerability scanner |
| Nessus Expert | $6,790/year | Adds external attack surface scanning to Nessus Professional |
Multi-year terms reduce the effective annual rate on Nessus and Vulnerability Management products. Full Tenable One packages require a custom quote based on asset count and modules needed, so budget for a sales conversation before committing. Confirm current pricing directly with Tenable, since security platform pricing is typically negotiated per organization.
Pros and cons
| Pros | Cons |
|---|---|
| Covers network, cloud, and web application exposure in one platform | Full Tenable One pricing is not published and requires a sales quote |
| Attack path analysis helps small security teams prioritize limited time | Enterprise-grade platform can be more than a small IT team needs |
| Nessus offers a lower-cost entry point for scanning alone | Standalone product pricing still runs in the thousands per year |
Who it’s for
Tenable fits impact organizations with a dedicated IT or security function, or those handling sensitive beneficiary and donor data at a scale that makes a breach materially damaging to trust and funding.
Who should skip it
If your organization is small, uses mostly cloud-hosted SaaS tools with vendor-managed security, and has no dedicated IT staff, Tenable’s scanning platform is likely more infrastructure than you need to manage.
How to get started
Start with Nessus if you need straightforward vulnerability scanning, or request a Tenable One quote if your organization needs exposure visibility across cloud, web, and network assets together.
FAQ
Is Nessus the same as Tenable One?
No. Nessus is a standalone vulnerability scanner, while Tenable One is the broader exposure management platform that includes multiple security modules.
Does Tenable cover cloud infrastructure, not just on-premises networks?
Yes. Tenable One includes cloud workload protection alongside traditional network and web application scanning.
Is Tenable pricing published for every product?
No. Standalone products like Nessus publish list pricing, but full Tenable One packages require a custom quote based on your asset count.
