DuckIntel / Security Tools
DuckIntel is a free cyber intelligence platform with 59 browser-based security tools. Runs entirely in your browser. No login, no tracking, nothing stored.
DuckIntel is a free, browser-based cyber intelligence platform built for SOC analysts, IT administrators, security researchers, and anyone learning cybersecurity. Every tool runs entirely in your browser — no login, no account, no data ever sent to DuckIntel servers. With 59 tools across analysis, investigation, training, and GRC, it is one of the most comprehensive free security toolkits available online.
The platform was built out of frustration with paywalled tools and fragmented workflows. Analysts constantly switch between a dozen browser tabs, each with a different lookup site. DuckIntel brings the most common analyst workflows together in one place: paste an email header, decode a suspicious payload, pivot on an IP, extract IOCs, check a CVE, and build a detection rule — all without leaving the site.
DuckIntel is entirely client-side. There is no backend database, no user accounts, and no tracking beyond Google Analytics page views. Sensitive data like email headers, log files, and decoded payloads never leave your machine. All computation happens in your browser using standard Web APIs.
