The following section outlines the core features, and briefly explains why this data might be useful for you to know, as well as linking to further resources for learning more.
IP Info
Description
An IP address (Internet Protocol address) is a numerical label assigned to each device connected to a network / the internet. The IP associated with a given domain can be found by querying the Domain Name System (DNS) for the domain's A (address) record.
Use Cases
Finding the IP of a given server is the first step to conducting further investigations, as it allows us to probe the server for additional info. Including creating a detailed map of a target's network infrastructure, pinpointing the physical location of a server, identifying the hosting service, and even discovering other domains that are hosted on the same IP address.

SSL Chain
Description
SSL certificates are digital certificates that authenticate the identity of a website or server, enable secure encrypted communication (HTTPS), and establish trust between clients and servers. A valid SSL certificate is required for a website to be able to use the HTTPS protocol, and encrypt user + site data in transit. SSL certificates are issued by Certificate Authorities (CAs), which are trusted third parties that verify the identity and legitimacy of the certificate holder.
Use Cases
SSL certificates not only provide the assurance that data transmission to and from the website is secure, but they also provide valuable OSINT data. Information from an SSL certificate can include the issuing authority, the domain name, its validity period, and sometimes even organization details. This can be useful for verifying the authenticity of a website, understanding its security setup, or even for discovering associated subdomains or other services.

DNS Records
Description
This task involves looking up the DNS records associated with a specific domain. DNS is a system that translates human-readable domain names into IP addresses that computers use to communicate. Various types of DNS records exist, including A (address), MX (mail exchange), NS (name server), CNAME (canonical name), and TXT (text), among others.
Use Cases
Extracting DNS records can provide a wealth of information in an OSINT investigation. For example, A and AAAA records can disclose IP addresses associated with a domain, potentially revealing the location of servers. MX records can give clues about a domain's email provider. TXT records are often used for various administrative purposes and can sometimes inadvertently leak internal information. Understanding a domain's DNS setup can also be useful in understanding how its online infrastructure is built and managed.
Useful Links
Cookies
Description
The Cookies task involves examining the HTTP cookies set by the target website. Cookies are small pieces of data stored on the user's computer by the web browser while browsing a website. They hold a modest amount of data specific to a particular client and website, such as site preferences, the state of the user's session, or tracking information.
Use Cases
Cookies can disclose information about how the website tracks and interacts with its users. For instance, session cookies can reveal how user sessions are managed, and tracking cookies can hint at what kind of tracking or analytics frameworks are being used. Additionally, examining cookie policies and practices can offer insights into the site's security settings and compliance with privacy regulations.

Crawl Rules
Description
Robots.txt is a file found (usually) at the root of a domain, and is used to implement the Robots Exclusion Protocol (REP) to indicate which pages should be ignored by which crawlers and bots. It's good practice to avoid search engine crawlers from over-loading your site, but should not be used to keep pages out of search results (use the noindex meta tag or header instead).
Use Cases
It's often useful to check the robots.txt file during an investigation, as it can sometimes disclose the directories and pages that the site owner doesn't want to be indexed, potentially because they contain sensitive information, or reveal the existence of otherwise hidden or unlinked directories. Additionally, understanding crawl rules may offer insights into a website's SEO strategies.
Useful Links
Headers
Description
The Headers task involves extracting and interpreting the HTTP headers sent by the target website during the request-response cycle. HTTP headers are key-value pairs sent at the start of an HTTP response, or before the actual data. Headers contain important directives for how to handle the data being transferred, including cache policies, content types, encoding, server information, security policies, and more.
Use Cases
Analyzing HTTP headers can provide significant insights in an OSINT investigation. Headers can reveal specific server configurations, chosen technologies, caching directives, and various security settings. This information can help to determine a website's underlying technology stack, server-side security measures, potential vulnerabilities, and general operational practices.

Quality Metrics
Description
Using Lighthouse, the Quality Metrics task measures the performance, accessibility, best practices, and SEO of the target website. This returns a simple checklist of 100 core metrics, along with a score for each category, to gauge the overall quality of a given site.
Use Cases
Useful for assessing a site's technical health, SEO issues, identify vulnerabilities, and ensure compliance with standards.
Useful Links
Server Location
Description
The Server Location task determines the physical location of the server hosting a given website based on its IP address. This is done by looking up the IP in a location database, which maps the IP to a lat + long of known data centers and ISPs. From the latitude and longitude, it's then possible to show additional contextual info, like a pin on the map, along with address, flag, time zone, currency, etc.
Use Cases
Knowing the server location is a good first step in better understanding a website. For site owners this aids in optimizing content delivery, ensuring compliance with data residency requirements, and identifying potential latency issues that may impact user experience in specific geographical regions. And for security researchers, it helps assess the risk posed by specific regions or jurisdictions regarding cyber threats and regulations.
Useful Links
Associated Hosts
Description
This task involves identifying and listing all domains and subdomains (hostnames) that are associated with the website's primary domain. This process often involves DNS enumeration to discover any linked domains and hostnames, as well as looking at known DNS records.
Use Cases
During an investigation, understanding the full scope of a target's web presence is critical. Associated domains could lead to uncovering related projects, backup sites, development/test sites, or services linked to the main site. These can sometimes provide additional information or potential security vulnerabilities. A comprehensive list of associated domains and hostnames can also give an overview of the organization's structure and online footprint.
Useful Links
Redirect Chain
Description
This task traces the sequence of HTTP redirects that occur from the original URL to the final destination URL. An HTTP redirect is a response with a status code that advises the client to go to another URL. Redirects can occur for several reasons, such as URL normalization (directing to the www version of the site), enforcing HTTPS, URL shorteners, or forwarding users to a new site location.
Use Cases
Understanding the redirect chain can be useful for several reasons. From a security perspective, long or complicated redirect chains can be a sign of potential security risks, such as unencrypted redirects in the chain. Additionally, redirects can impact website performance and SEO, as each redirect introduces additional round-trip-time (RTT). For OSINT, understanding the redirect chain can help identify relationships between different domains or reveal the use of certain technologies or hosting providers.
Useful Links
TXT Records
Description
TXT records are a type of DNS record that provides text information to sources outside your domain. They can be used for a variety of purposes, such as verifying domain ownership, ensuring email security, and even preventing unauthorized changes to your website.
Use Cases
The TXT records often reveal which external services and technologies are being used with a given domain. They may reveal details about the domain's email configuration, the use of specific services like Google Workspace or Microsoft 365, or security measures in place such as SPF and DKIM. Understanding these details can give an insight into the technologies used by the organization, their email security practices, and potential vulnerabilities.

Server Status
Description
Checks if a server is online and responding to requests.

Open Ports
Description
Open ports on a server are endpoints of communication which are available for establishing connections with clients. Each port corresponds to a specific service or protocol, such as HTTP (port 80), HTTPS (port 443), FTP (port 21), etc. The open ports on a server can be determined using techniques such as port scanning.
Use Cases
Knowing which ports are open on a server can provide information about the services running on that server, useful for understanding the potential vulnerabilities of the system, or for understanding the nature of the services the ser
