Why vulnerability scanning matters
Regular vulnerability scanning helps you identify and fix security issues before attackers exploit them. This tool provides:
- Early detection: Find vulnerabilities before they're exploited in production
- Risk prioritization: Focus on critical vulnerabilities first with severity scoring
- Compliance support: Meet security scanning requirements for PCI DSS, HIPAA, SOC 2
- Continuous monitoring: Track vulnerabilities over time and detect new issues
- Remediation guidance: Get actionable steps to fix each vulnerability
Combine automated vulnerability scanning with manual security testing for comprehensive coverage. Use this tool for regular security assessments and continuous vulnerability monitoring.
What to do with vulnerability scan results
After scanning for vulnerabilities, prioritize remediation based on risk severity:
- Critical security issues: Address immediately (missing security headers, weak TLS configuration, exposed sensitive information)
- High-risk issues: Fix within 7 days (insecure cookies, vulnerable libraries, security misconfigurations)
- Medium-risk issues: Plan remediation within 30 days (misconfigurations, weak encryption)
- Low-risk findings: Address during regular maintenance cycles
Document all fixes, verify remediation with rescanning, and establish a regular scanning schedule. For complex vulnerabilities or compliance requirements, consider engaging security professionals for validation and deeper analysis.
