OWASP ASVS Assessments

A penetration test focuses primarily on finding exploitable vulnerabilities at a point in time, while an ASVS assessment takes a more comprehensive defense-in-depth approach. ASVS is not only about assessing vulnerabilities but also evaluating the security controls that make your application resilient against attacks. It applies a multi-layered security approach, ensuring that if one control fails, others remain in place to protect your application. This means that even if a vulnerability is discovered, its impact or effectiveness is greatly mitigated by other security measures. For example, a penetration test might identify an injection vulnerability, but an ASVS assessment would verify multiple layers of protection including: input validation, parameterized queries, least privilege database access, proper error handling, and logging/monitoring systems. This multi-faceted approach helps build applications that can withstand various attack scenarios rather than just fixing individual vulnerabilities. For comprehensive security, we recommend combining both approaches: penetration testing to identify current exploitable vulnerabilities and ASVS assessment to build systemic resilience through properly implemented security controls.

The duration depends on the complexity of your application and the ASVS level selected. A Level 1 assessment typically takes 1-2 weeks, a Level 2 assessment 2-3 weeks, and a Level 3 assessment 3-4 weeks. These timeframes include assessment, reporting, and initial consultation on remediation steps. The verification phase after remediation is typically conducted as a separate engagement.

The appropriate level depends on your application's risk profile and business context. Level 1 is suitable for applications with minimal security requirements. Level 2 is appropriate for applications handling sensitive business data or personal information. Level 3 is designed for critical applications processing highly sensitive data (financial, healthcare, government) or requiring the highest level of trust. During our initial consultation, we'll help you determine the most appropriate level based on factors like data sensitivity, regulatory requirements, and threat exposure.

Our deliverables include a comprehensive assessment report detailing compliance status for each applicable ASVS requirement, with clear explanations of gaps and specific remediation guidance. We also provide an executive summary highlighting key findings and recommendations, prioritized by risk level. After remediation and verification, we can issue a Letter of Attestation certifying your application's compliance with the specified ASVS level, which can be shared with clients, partners, or regulators as evidence of your security posture.

We recommend conducting a full ASVS assessment annually, and incremental assessments after significant changes to your application or infrastructure. For applications with high security requirements or those undergoing frequent changes, more frequent assessments may be appropriate. Many organizations pair annual ASVS assessments with quarterly penetration tests for comprehensive security coverage throughout the year.
