CyberRisk will scan any site belonging to you or any of the vendors you are following at least once a day. In addition, you can explicitly request a scan by viewing the scan results for a given website and then pressing the "scan" button.
When CyberRisk scans a website it collects data from a variety of sources. Most of this data collection occurs straight away, and any changes made to a website will therefore be reflected in CyberRisk.
Certain data (in particular port scan results and some attributes related to TLS version) is collected less frequently, and may take several days to flow through. When you explicitly request a scan (by pressing the 'scan' button), a port scan is scheduled, and the results will be visible within a day. Note that when ports change from “open” to “filtered” (as opposed to “closed”), it may still take up to 30 days for changes to flow through.
