Abuseipdb helps search threat intelligence, IP reputation, domains, and security investigation data.
A web-based tool that tests the IPv6 readiness of an internet domain and shows whether the visitor's own connection supports IPv6. It reports DNS-based results, including nameserver and mail exchanger records, and maintains a Hall of Fame of domains scoring five stars. It also warns when an embedded MAC-address identifies the device. The site requires JavaScript.
Certbot is a tool run from the command line to obtain and install HTTPS certificates. It can either be run once to get free HTTPS certificates or used with instructions generated for a server's software and system. Using it requires comfort with the command line and an HTTP website. The project is a project of the Electronic Frontier Foundation.
CheckFileType is a free online tool that determines a file's true type, extension and MIME type from its contents rather than its extension. Users upload a file without registration, and the tool can look inside archives such as ZIP files to report the type of each contained file. Files are stored temporarily and removed after one hour.
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.
Demo is a developer resource for coding, documentation, communities, security research, or software tools.
A free online tool that converts supplied text into an image file in GIF, JPEG or PNG format. Users choose text up to 500 characters, dimensions between 10 and 1500 pixels, font size from 6pt to 54pt, and foreground and background colors, then download the image or link to it. The site stores choices in a database and a cookie.
