# Get all vulnerabilities with a CVSS score > 7 affecting Windows servers
vulns = tio.exports.vulns(
    severity=['high', 'critical'],
    plugin_family='Windows',
    last_found=30  # Last 30 days
)

# Process the results
for vuln in vulns:
    print(f"Host: {vuln['asset']['hostname']}")
    print(f"IP: {vuln['asset']['ipv4']}")
    print(f"Vulnerability: {vuln['plugin']['name']}")
    print(f"CVSS: {vuln['plugin']['cvss_base_score']}")

SolarWinds’ solutions are likely to be most appropriate for organizations that:

• Prioritize Operational Integration: Need security monitoring as part of a broader IT operations management approach
• Have Limited Security Specialization: Operate with IT generalists rather than dedicated security teams
• Seek Balanced Coverage: Require moderate capabilities across both operational and security monitoring
• Value Deployment Simplicity: Prioritize ease of deployment and management over depth of security capabilities
• Have Budget Constraints: Need to balance security capabilities with cost considerations

When Tenable May Be the Better Choice

Tenable’s solutions are typically better suited for organizations that:

• Prioritize Security Depth: Require comprehensive vulnerability management and security assessment capabilities
• Have Dedicated Security Teams: Operate with specialized security personnel who can leverage advanced capabilities
• Face Stringent Compliance Requirements: Must demonstrate comprehensive vulnerability management for regulatory compliance
• Manage Complex Environments: Need to secure diverse assets across traditional, cloud, and OT/IoT environments
• Require Advanced Risk Prioritization: Face more vulnerabilities than can be immediately remediated and need sophisticated prioritization

Hybrid Approaches and Complementary Deployments

Many organizations, particularly larger enterprises, may find value in using both vendors for their respective strengths:

• SolarWinds for Operational Monitoring: Leveraging SolarWinds’ strengths in performance monitoring and general IT operations
• Tenable for Security Assessment: Utilizing Tenable’s depth in vulnerability management and security-specific functions
• Integration Between Platforms: Creating workflows that leverage data from both systems for comprehensive visibility

This hybrid approach allows organizations to benefit from each vendor’s strengths while mitigating their respective limitations. Effective integration between the platforms becomes critical in this scenario to avoid creating operational silos.

The choice between SolarWinds and Tenable ultimately depends on organizational priorities, existing capabilities, and strategic direction. Rather than viewing this as a binary choice, security leaders should carefully assess their specific requirements and consider how each vendor’s strengths and limitations align with their organization’s needs.

As security challenges continue to evolve, the most successful organizations will be those that thoughtfully align their tool selection with their security program maturity, team capabilities, and risk profile. Both SolarWinds and Tenable offer valuable capabilities, but the right choice depends on the specific context in which these tools will be deployed and used.
