FractalScan provides a health score from 1 to 5 for websites, network, mail, vulnerabilities, and an aggregate overall health score. When it comes to the scores, a high number is good. Take a look at this example from the Health section:
There is an overview of what is covered under each category on the associated tab in the above view, with information on how a risk is categorised. As an example, the websites category will report potential configuration issues on websites, whereas the vulnerabilities category will report on any issues with versioned software found across the infrastructure that FractalScan can see. Using this example, a CVE could be shown as being against the seed, but by looking at the Health tabs, you will be able to see that it is a vulnerability with software related to the infrastructure hosting that domain. The overall aggregate score may show as a lower value than any other category score since it combines the risks across all four categories.
Using the Risks section, click on the risk of interest and scroll down to see the provenance diagram, which provides more information on where the issue resides and how it links to the seed. See the Managing Risks section for more information on risks.
