Pulsedive is a free threat intelligence platform for searching, scanning and enriching IPs, URLs, domains and other IOCs from OSINT feeds or submitted data. It supports on-demand passive or active scans and a query language for pivoting across indicators and threats, with export options. Paid tiers are listed for non-commercial and commercial use, including API and feed access.
A free domain research tool that discovers hosts related to a domain and looks up DNS records. It presents visible hosts from an attacker's perspective for red and blue teams, and is intended for reconnaissance, penetration testing, bug bounties, threat analysis and network OSINT.
Iocaine is a developer resource for coding, documentation, communities, security research, or software tools.
URLhaus is a platform operated by abuse.ch with the purpose of sharing malicious URLs used for malware distribution. It allows reporting URLs and browsing a database of malicious URLs. APIs enable pushing and pulling signals and automating bulk queries, and Spamhaus datasets enhanced by URLhaus are offered for threat hunting, email protection and network protection.
UUID Tools is an open-source, free online tool and API for generating UUIDs and GUIDs on the fly, including version-1, version-3, version-4 and version-5. The API requires no authentication, allows up to 100 UUIDs per request and is limited to 60 requests per minute per IP address. It also offers a UUID decoder and bulk generator.
GNUnet is GNU's framework for secure peer-to-peer networking. It is described as a network protocol stack for building secure, distributed and privacy-preserving applications, aiming to replace the existing Internet protocol stack, and is free software.
Let's Encrypt is a free, automated, and open Certificate Authority operated by the nonprofit Internet Security Research Group. It provides free TLS certificates so websites can enable HTTPS encryption; obtaining a certificate requires demonstrating control over the domain, and issuance uses the ACME protocol with client software.
