Features, pricing, ratings, and pros and cons, compared head to head.
DerScanner Dynamic Application Security Testing (DAST) is a commercial dynamic application security testing tool by DerSecur. Tenable One Web App Scanning is a commercial dynamic application security testing tool by Tenable. Compare features, ratings, integrations, and community reviews side by side to find the best dynamic application security testing fit for your security stack. Independent and vendor-neutral: our scores and rankings are earned, never bought — sponsored placement is always labeled.
SMB and mid-market teams running web applications without dedicated AppSec staff should start with DerScanner Dynamic Application Security Testing because unlimited scan frequency and automated vulnerability prioritization let you find exploitable flaws without needing security expertise to tune the scanner. The passive network scanner plus AJAX support mean you'll catch real-world attack paths that traditional DAST tools miss on asynchronous applications. Skip this if you need SAST-first workflows or have complex API-only architectures; DerScanner prioritizes live application scanning over source code analysis. Development and security teams shipping APIs and single-page applications need fast feedback loops, and Tenable Web App Scanning delivers results in two minutes or less with CI/CD integration built in. The tool covers OWASP Top 10 vectors including XSS and SQL injection across both web apps and APIs, plus third-party component scanning that catches what developers often miss. Skip this if you need deep API fuzzing or runtime protection; Tenable is a scanner, not a WAF, and prioritizes finding known issues over behavioral anomaly detection.
Based on our analysis of core features, integrations, company size fit, deployment model, here is our conclusion:
