Version Number: v1.0.1 Published Date: 29 Sep 2026 \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ The Investigations page provides a detailed breakdown of tasks involved in the investigation, categorised as either "Required" or "Optional": Investigation settings marked as required are mandatory as part of any investigation. | **Task** | **Task Description** | **Requirements** | | --- | --- | --- | | Brute-force Subdomain Enumeration | Uses a brute-force approach to guess potential subdomains of target domains | Required | | HTTP(s) Probe | Probe HTTP(s) service availability and status. Note that this is redundant if you are also using the Service Discovery task. It is offered as a lightweight alternative for situations where port scanning would not be appropriate | Required | | Last Registrant Retrieval | Retrieves the last (most recent) registrant of a domain | Required | | DNS Resolution | Resolves the DNS records of a domain | Required | | Subdomain discovery | Discovers subdomains of target domains by querying publicly available resources like search engines and social media | Required | | Analyze TLS configuration | Analyzes and grades the TLS configuration of web applications running on a domain | Optional | | HTTP Defensive Header Grading | Grade defensive headers for http and https services. Defensive headers include Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, X-XSS-Protection, and Referrer-Policy | Optional | | Domain Registration Exploration | Finds domains that are registered or have been registered in the past by the same entity that registered a target domain | Optional | | Certificate Retrieval | Retrieves certificates for domains and reports their validity and expiration dates | Optional | | Service Discovery | Discover open ports and running services on discovered domains | Optional | | Typosquatting and Similar Domain Discovery | Reports domains that are lexicographically similar to target domains. This can help identify typosquatting and domains using other TLDs with the same name. Note that this task can take a long time to complete and may generate a lot of noise | Optional | | Web Content Analyzer | Analyze the content of a web page, extracting domains from links, and metadata | Optional |   ### Task Types Platform Selection ![](https://kb.edgescan.com/hs-fs/hubfs/image-png-Sep-29-2026-08-41-11-3399-AM.png?width=670&height=683&name=image-png-Sep-29-2026-08-41-11-3399-AM.png)       -
