CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Penetration testers and red teamers running targeted social engineering campaigns will extract immediate value from Linkedin2username because it automates the messiest part of username enumeration, turning a company's public LinkedIn roster into attack-ready lists in seconds. The tool's 1,642 GitHub stars and zero friction deployment (free, no auth required) make it the fastest way to build realistic credential lists for phishing simulations without writing custom scrapers. Skip this if your scope is broader than social engineering testing; it does one thing and ignores everything else upstream like email validation or domain correlation.
