Free Tools
Six free cybersecurity tools built for analysts, responders, and defenders. Check IOCs against threat intel, investigate phishing, scan for exposure, look up domains, analyse suspicious files, and audit your browser privacy — no account, no paywall.
Built by DFIR Lab. Privacy-first by design — your data is never stored or shared.
IOC Reputation Checker
IP · domain · hash · URL
Check any IP, domain, hash, or URL against 14+ threat intelligence sources. Get instant reputation scoring, verdict, and shareable results. No signup, no limits beyond 10/hour.
Phishing Email Checker
Analyse suspicious emails
Paste raw email headers to check for phishing indicators, spoofing attempts, and SPF / DKIM / DMARC authentication failures. Instant results, no account needed.
Exposure Scanner
Map your attack surface
Scan any domain or IP for open ports, SSL/TLS misconfigurations, exposed services, and attack surface indicators. Understand what attackers see before they do.
Domain Lookup
Investigate any domain
Full WHOIS records, DNS enumeration, email security posture (SPF/DKIM/DMARC), and reputation scoring — all in a single query. Essential for phishing and fraud investigations.
File Analyzer
Static analysis for suspicious files
Upload scripts, documents, or executables for static analysis. Detects obfuscation, suspicious patterns, embedded URLs, and indicators of compromise without executing the file.
Browser Privacy Check
Audit your browser fingerprint
See what your browser reveals to websites: IP address, WebRTC leaks, canvas fingerprint, installed fonts, and more. Understand your digital footprint in seconds.
API Playground
Try every endpoint in your browser
Interactive playground for the full DFIR Platform API. 10 free calls per week — no signup. Test IOC enrichment, phishing analysis, exposure scans, and more against real endpoints.
Every tool on this page is built and operated by DFIR Lab — an independent security research project. We don't require accounts, we don't log queries, and we don't sell your data.
Need higher rate limits, API access, or team features? The DFIR Platform extends these tools with a free tier and pay-as-you-go API.
