What Is Tenable Web Application Scanning and How Does It Work?
Tenable Web Application Scanning (WAS) is a robust security tool that helps you find, analyze, and fix vulnerabilities in your web applications. Designed by Tenable, a leading name in cybersecurity, WAS automates the process of identifying security risks in websites and web-based applications.
If you develop, manage, or use web applications, understanding and using a scanning solution like Tenable WAS is crucial. It keeps your applications protected against attacks, ensuring your data and your users remain safe.
How Tenable Web Application Scanning Works
Tenable WAS operates by continuously scanning your web applications for known vulnerabilities, weak configurations, and potential security gaps. Here’s a simple breakdown of how it functions:
- Crawling: The scanner explores your web application, mapping all accessible pages, forms, and endpoints.
- Testing: It simulates various attack techniques, such as SQL injection and cross-site scripting (XSS), to check for vulnerabilities.
- Analysis: The tool analyzes responses and identifies security issues, examining both the front-end and back-end.
- Reporting: You receive detailed reports highlighting risks, affected areas, and recommended fixes.
Tenable WAS can be integrated into your development pipeline, allowing you to catch security issues early and often.

Step-by-Step: Setting Up and Running a Tenable WAS Scan
Let’s break down how to get started with Tenable Web Application Scanning:
1. Define the Scope
- List the web applications, APIs, or endpoints you want to scan.
- Set the allowable scan depth to avoid scanning unreleased or sensitive parts of your application.
2. Configure Credentials (If Needed)
- Enter authentication credentials if your application requires login.
- Use this to ensure internal pages and user-only areas are tested.
3. Set the Scan Schedule
- Choose a one-time or recurring scan.
- Consider scanning during non-peak hours to reduce potential performance impacts.
4. Run the Scan
- Initiate the process through the easy-to-use dashboard.
- Monitor scan progress in real-time.
5. Review Reports
- Analyze results for detected vulnerabilities.
- Prioritize remediation based on the severity and exploitability.
6. Remediate Vulnerabilities
- Use actionable insights from the report to fix the issues.
- Rerun scans to confirm issues are resolved.
Main Benefits of Using Tenable Web Application Scanning
Using Tenable WAS brings a host of advantages, especially for organizations that rely on web-based applications:
- Enhanced Security Posture
Stay ahead of cyber threats by discovering vulnerabilities before attackers do. - Time and Resource Efficiency
Automate repetitive and complex manual testing, freeing up your security team for other critical tasks. - Proactive Compliance
Satisfy requirements for security standards like PCI DSS, HIPAA, or GDPR. - Continuous Improvement
Ongoing scanning ensures new code deployments don’t introduce fresh issues. - Reduced Attack Surface
Quickly patch or remove vulnerabilities, minimizing potential entry points for attackers.
Challenges and Considerations
While Tenable WAS is powerful, there are some factors to keep in mind:
- Coverage Limitations: Some complex or heavily dynamic applications may not be fully mapped without custom configuration.
- False Positives/Negatives: Like any automated tool, it may occasionally flag legitimate functionalities as threats or miss subtle vulnerabilities.
- Credentialed Scanning Complexity: Setting up authentication for complex login systems may take effort and testing.
- Performance Impact: Scanning can temporarily impact application speed, so schedule wisely to avoid disrupting users.
- Integration Overhead: Adding scanning to complex CI/CD pipelines might require custom setups.
Recognizing these challenges helps you plan effective and reliable scans.
Best Practices for Effective Tenable Web Application Scanning
To get the most out of Tenable WAS, consider these practical tips:
- Start with a Test Environment
Run initial scans on staging servers to avoid impacting live users and systems. - Schedule Regular Scans
Weekly or monthly scans keep you protected against new and emerging threats. - Prioritize High-Risk Findings
Address critical and high-severity vulnerabilities first to minimize risk. - Integrate with Development Workflows
Use Tenable’s integration capabilities to catch vulnerabilities before deployment. - Train Your Team
Ensure developers and administrators know how to interpret findings and remediate quickly. - Monitor and Adjust Scope
Regularly update your scan targets as applications evolve or new components are added. - Document and Track Remediation Efforts
Use the reporting features to maintain records of scans and fixes for auditing and compliance. - Leverage Reporting and Analytics
Use built-in dashboards to track trends, monitor recurring issues, and demonstrate improvements.
Pricing and Cost Tips
While this article doesn’t provide specific prices, here are general cost-related considerations:
- Licensing Model: Tenable WAS typically uses a subscription or per-application pricing.
- Free Trials: Take advantage of free trials or pilot programs to evaluate suitability.
- Package Bundles: Many businesses benefit from bundled solutions if they also want network or host vulnerability scanning alongside WAS.
- Scalable Plans: Choose plans that match your current and future application inventory to avoid overpaying.
- Cloud-Based vs. On-Premises: Cloud options reduce up-front infrastructure costs and are faster to deploy.
No shipping costs apply, as WAS is offered as a cloud-hosted or self-managed solution, making deployment simple and direct.
