Safety rating is a color-coded safety category for a website.
A Trellix team analyzes each website and assigns a color-coded safety rating based on test results. The color indicates the safety level of the site. The team develops safety ratings by testing criteria for each site and evaluating the results to detect common threats.
Automated tests compile safety ratings for a website by:
Downloading files to check for viruses and potentially unwanted programs bundled with the download.
Entering contact information into sign-up forms and checking for resulting spam or a high volume of non-spam email sent by the site or its affiliates.
Checking for an excessive number of pop-up windows.
Checking for attempts by the site to exploit browser vulnerabilities.
Checking for deceptive or fraudulent practices that a site uses.
The team compiles test results into a safety report that can also include:
Feedback submitted by site owners, which might include descriptions of safety precautions used by the site or responses to user feedback about the site.
Feedback submitted by site users, which might include reports of phishing scams or bad shopping experiences.

The Trellix GTI server stores site ratings. The server is updated periodically with the latest rating and site details.
