Pricing

Pricing structures for enterprise vulnerability management platforms vary significantly. These tools generally operate on subscription models, often based on the number of assets, IP addresses, or modules required. Direct price comparisons are challenging due to customized quotes.

Qualys VMDR: Qualys employs a modular pricing model. Organizations purchase specific applications (e.g., VMDR, WAS, CSAM, Patch Management) based on their needs. Pricing scales with the number of assets or IP addresses scanned. This approach allows flexibility but can lead to higher costs for extensive feature sets. Pricing is enterprise, quote-based; contact Qualys directly for a personalized quote.

Tenable One: Tenable offers different tiers, often based on the number of assets or users. Their flagship Tenable One platform bundles various capabilities like vulnerability management, web application scanning, and cloud security. Nessus Professional, a standalone scanner, is sold as a fixed annual subscription per license. For Tenable One, pricing is enterprise, quote-based and volume-based, requiring direct vendor engagement for accurate figures.

Rapid7 InsightVM: Rapid7 InsightVM typically prices based on the number of assets (physical or virtual machines) monitored. It often includes the Nexpose scanning engine and Insight Agent. Additional modules like InsightAppSec (for web application scanning) or InsightCloudSec (for cloud security) are separate add-ons. Rapid7 pricing is enterprise, quote-based; expect asset-based annual subscriptions (typically sold from a 500-asset minimum).

Secably: Secably offers a transparent pricing model, including a free tier for instant tools. These tools include a free port scanner and an SSL/TLS certificate checker. Paid monitoring plans start at $19/month. This structure makes Secably accessible for smaller teams or those focused purely on continuous external attack surface monitoring. See Secably pricing for detailed plans.

Verdict: Which to Pick

Choosing the right vulnerability management solution depends on your organization's specific needs, budget, and existing security posture. No single tool fits every scenario.

For large enterprises with complex, hybrid environments: Qualys VMDR, Tenable One, and Rapid7 InsightVM all present strong options. Qualys excels in its broad, integrated suite and compliance reporting. Tenable offers deep technical scanning and strong cloud/OT security. Rapid7 focuses on risk prioritization and attacker insights. Your choice here often comes down to existing vendor relationships, preferred risk methodology, and specific module needs (e.g., strong patch management, extensive cloud security).

For mid-sized organizations with growing security programs: Rapid7 InsightVM often provides a good balance of features, ease of use, and actionable intelligence. Tenable.io is also a strong contender, especially if deep technical scanning and a wide range of asset types (including OT) are priorities. Qualys remains viable, but its modular pricing can sometimes lead to higher costs if many features are needed. Consider a detailed proof-of-concept for each.

For small businesses or teams focused purely on external exposure: Secably offers an excellent entry point. Its free tools and low-cost continuous monitoring plans provide valuable external attack surface management without the complexity or cost of enterprise VM suites. It is ideal for identifying internet-facing risks, forgotten assets, and basic web vulnerabilities. For internal scanning, you would need to pair Secably with another solution, possibly an open-source scanner like OpenVAS or a more traditional commercial tool.

Where Secably Fits

Secably occupies a distinct niche in the security tool ecosystem, focusing on the external attack surface. It is not a direct replacement for the comprehensive internal vulnerability management suites offered by Qualys, Tenable, or Rapid7. Instead, Secably acts as a specialized, complementary solution.

Secably excels at continuous, automated reconnaissance of your internet-facing assets. It helps answer the critical question: "What does an attacker see?" This includes discovering forgotten subdomains, exposed services, misconfigured DNS records, and basic web vulnerabilities. Secably's strength lies in its simplicity and continuous monitoring capabilities, providing real-time alerts on changes to your external footprint. Read more about this in What Every Engineer Should Know About Continuous Attack Surface Management.

Organizations often pair Secably with their existing internal vulnerability management platforms. Secably identifies external risks, while tools like Qualys, Tenable, or Rapid7 manage internal network and endpoint vulnerabilities. This combination provides a more complete picture of an organization's overall security posture. Secably's free tier and affordable paid plans make it accessible for any team, from startups to enterprises, to enhance their external visibility. Secably acknowledges the deep internal scanning and extensive feature sets of its competitors; it aims to fill the external blind spots they might miss or handle less continuously.
