No-as-a-Service (NaaS) is a simple API that returns a random rejection reason. Use it when you need a realistic excuse, a fun “no,” or want to simulate being turned down in style.
Vulnerability-Lookup facilitates quick correlation of vulnerabilities from various sources, independent of vulnerability IDs, and streamlines the management of Coordinated Vulnerability Disclosure (CVD). Vulnerability-Lookup is also a collaborative platform where users can comment on security advisories and create bundles.
Has a comprehensive and fast lookup API for searching vulnerabilities and identifying correlations by vulnerability identifier. Modular system to import vulnerabilities from different sources. Management of Security Advisories and Vulnerability Disclosures. Support of local vulnerability sources per instance. Users have the possibility to add observations to vulnerabilities with different types of sightings, such as: seen, exploited, not exploited, confirmed, not confirmed, patched, and not patched. Add, review and share comments on vulnerability advisories. Create bundles of vulnerability advisories with a description. RSS and Atom support for vulnerabilities and comments. Integration of the Exploit Prediction Scoring System. Track vulnerabilities with your custom product watch lists and receive email notifications. Almost two dozen vulnerability sources and feeders supported.
Access to reliable and timely information about vulnerabilities affecting Information and Communication Technology (ICT) products and services contributes to an enhanced cybersecurity risk management. Sources of publicly available information about vulnerabilities are an important tool for users of these services, competent authorities, and the broader cybersecurity community. ENISA has established a European Vulnerability Database (EUVD) where entities, regardless of whether they fall within the scope of the NIS2 Directive, and their suppliers of network and information systems, as well as competent authorities, most notably CSIRTs, can voluntarily disclose and register publicly known vulnerabilities to allow users to take appropriate mitigating measures.
In line with Coordinated Vulnerability Disclosure practices, which aim at providing improved transparency regarding the publication process, the EUVD is eventually used to publicly disclose the vulnerability information.
To avoid efforts duplication and to support complementarity, ENISA closely cooperates with MITRE and European as well as non-European operators of the Common Vulnerabilities and Exposures (CVE) system. In this context, ENISA offers vulnerability registry services after its onboarding as a CVE Numbering Authority (CNA), with a focus on vulnerabilities in IT products discovered by or reported to European CSIRTs for coordinated disclosure.
The Registration Data Access Protocol (RDAP) is the successor to WHOIS. Like WHOIS, RDAP provides access to information about Internet resources (domain names, autonomous system numbers, and IP addresses). Unlike WHOIS, RDAP provides:
RDAP.org aims to support users and developers of RDAP clients by providing a "bootstrap server", i.e. single end point for RDAP queries. RDAP.org aggregates information about all known RDAP servers. RDAP clients can send RDAP queries to RDAP.org, which will then redirect requests to the appropriate RDAP service.
FreeDATA is a versatile, open-source platform designed specifically for HF communications, leveraging Codec2 data modes for robust global digital communication.

Beszel is a lightweight server monitoring platform that includes Docker statistics, historical data, and alert functions. It has a friendly web interface, simple configuration, and is ready to use out of the box. It supports automatic backup, multi-user, OAuth authentication, and API access.
Smaller and less resource-intensive than leading solutions. Easy setup, no need for public internet exposure. Configurable alerts for CPU, memory, disk, bandwidth, temperature, and status. Users manage their own systems. Admins can share systems across users. Supports many OAuth2 providers. Password auth can be disabled. Save and restore data from disk or S3-compatible storage.
Consists of a hub built on PocketBase that provides a dashboard for viewing and managing connected systems and an agent that runs on each system you want to monitor, creating a minimal SSH server to communicate system metrics to the hub.
Seems to be designed with system monitoring in mind, and as such isn't really that flexible.
The CVEDB API offers a quick way to check information about vulnerabilities in a service. You can search using either the CVE-ID or CPE23.
A vulnerability lookup service by SHODAN.
Free for non-commercial use (i.e., selling the data). You don't need a SHODAN API key.
An open source threat intel and sharing platform. Lots of ad-hoc visualization methods are available to make sense of data. Includes lots of taxonomies to organize data and do some of the work for you.
You can store your IOCs in a structured manner, and thus enjoy the correlation, automated exports for IDS, or SIEM, in STIX or OpenIOC and synchronize to other MISPs. You can now leverage the value of your data without effort and in an automated manner. The primary goal of MISP is to be used. This is why simplicity is the driving force behind the project. Storing and especially using information about threats and malware should not be difficult. MISP is there to help you get the maximum out of your data without unmanageable complexity. MISP will make it easier for you to share with, but also to receive from trusted partners and trust-groups. Sharing also enabled collaborative analysis and prevents you from doing the work someone else already did before.
Threat Intelligence is much more than Indicators of Compromise. This is why MISP provides metadata tagging, feeds, visualization and even allows you to integrate with other tools for further analysis thanks to its open protocols and data formats. Having access to a large amount of Threat information through MISP Threat Sharing communities gives you outstanding opportunities to aggregate this information and take the process of trying to understand how all this data fits together telling a broader story to the next level. We are transforming technical data or indicators of compromise (IOCs) into cyber threat intelligence. MISP comes with many visualization options helping analysts find the answers they are looking for.

While xthulu is intended to be a community server with multiple avenues of interaction (e.g. terminal, browser, REST API), its primary focus is to provide a modern SSH terminal interface which pays homage to the bulletin boards of the 1990s. Rather than leaning entirely into DOS-era nostalgia, modern character sets (UTF-8) and terminal capabilities are taken advantage of.

IndexNow is an easy way for websites owners to instantly inform search engines about latest content changes on their website. In its simplest form, IndexNow is a simple ping so that search engines know that a URL and its content has been added, updated, or deleted, allowing search engines to quickly reflect this change in their search results.
Without IndexNow, it can take days to weeks for search engines to discover that the content has changed, as search engines don’t crawl every URL often. With IndexNow, search engines know immediately the "URLs that have changed, helping them prioritize crawl for these URLs and thereby limiting organic crawling to discover new content."
IndexNow is offered under the terms of the Attribution-ShareAlike Creative Commons License and has support from Microsoft Bing, Naver, Seznam.cz, Yandex, Yep.
IndexNow-enabled search engines shares immediately all URLs submitted to all other IndexNow-enabled search engines, so you just need to notify one endpoint.
Add dynamic content, forms or personalization to your static site, manage smart home, monitor server room temperatures in hundreds of locations using Raspberry Pi, or simply play with the API - JsonStorage is super simple and scales up to your needs.
The Polaric Server is mainly a web based service to present live tracking information (APRS, AIS, etc) on maps and where the information is updated in realtime. It is originally targeted for use by radio amateurs in voluntary search and rescue service in Norway. It consists of a web application and a server program (APRS daemon). It runs on e.g. aprs.no as a online service on the internet, but we could also bring it with us out in the field in a portable computer, possibly with its own LAN, APRS modems and radios. A goal is that it should be able to work without always being online with a good connection to the internet.
