o365recon is a free penetration testing tool. ParamSpider is a free penetration testing tool. Compare features, ratings, integrations, and community reviews side by side to find the best penetration testing fit for your security stack.
CST VerdictBased on our analysis of available product data, here is our conclusion:
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.
Bug bounty hunters and penetration testers doing recon on large attack surfaces should start with ParamSpider; it pulls historical URLs from the Wayback Machine and other archives to uncover forgotten endpoints and parameters that live code scans miss. The tool has 2,855 GitHub stars and requires only Python, meaning it integrates into existing workflows without infrastructure overhead. Skip this if you need active crawling of protected applications or real-time parameter discovery; ParamSpider depends entirely on what's already been indexed, which works well for external reconnaissance but won't help you find freshly deployed internal APIs.
