CST VerdictBased on our analysis of available product data, here is our conclusion:
Penetration testers and bug bounty hunters who need fast endpoint discovery during reconnaissance should start with hakrawler; it crawls web applications an order of magnitude quicker than manual mapping, with 4,841 GitHub stars reflecting sustained adoption by practitioners who run it continuously across engagement kickoffs. The tool's speed comes from its parallelized crawling architecture, which surfaces forgotten endpoints and asset exposure before deeper testing begins. Skip this if your mandate is vulnerability scoring or compliance reporting; hakrawler is reconnaissance-only, and you'll need separate tools for exploitation and risk quantification.
Penetration testers and red teamers running Office 365 assessments need o365recon because it pulls user enumeration, tenant configuration, and permission mappings from Azure AD using valid credentials, giving you reconnaissance data in minutes instead of hours of manual API queries. The tool's 731 GitHub stars and active maintenance reflect real adoption in offensive security workflows. Skip this if you're looking for unauthenticated reconnaissance or cloud infrastructure scanning beyond Microsoft's identity stack; o365recon assumes you already have compromised or test credentials and focuses narrowly on what those credentials expose.
