CST VerdictBased on our analysis of NIST CSF 2.0 coverage, company size fit, deployment model, here is our conclusion:
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.
Penetration testers and red team operators who need to reconstruct RSA private keys from captured cryptographic material will find rsatool indispensable; it's the fastest way to convert fragmented key components into usable OpenSSL formats for exploitation workflows. With 1,568 GitHub stars and active maintenance, the tool handles the math correctly where homegrown scripts usually fail. Skip this if your work doesn't involve post-compromise key recovery or if you need GUI-based key generation; rsatool assumes you're already comfortable with Python and understand what you're deriving.
