Lambda-Proxy vs Burp Suite Professional: 2026 Comparison

CST VerdictBased on our analysis of NIST CSF 2.0 coverage, company size fit, deployment model, here is our conclusion:
Penetration testers validating Lambda function security will find Lambda-Proxy invaluable for exposing SQL injection vulnerabilities that standard web application scanners miss, since it bridges SQLMap directly into AWS Lambda invoke calls through a local proxy. The tool is free and already battle-tested by security researchers, requiring no licensing overhead or vendor lock-in. Skip this if your team needs broad infrastructure scanning or compliance automation; Lambda-Proxy solves one problem exceptionally well and makes no apologies for the narrow scope.
Security teams responsible for web application penetration testing will get the most from Burp Suite Professional because its manual testing workflow is genuinely faster than competitors when you need to find logic flaws and authentication bypasses that automated scanners miss. The platform covers ID.RA and PR.PS functions across both on-premises and cloud deployments, and PortSwigger's 299-person team maintains the strongest passive scanning library in the category. Skip this if your team lacks dedicated web security engineers or if you need a tool that also handles API fuzzing and mobile testing equally well; Burp's mobile support lags, and the learning curve punishes casual users.
