About Zulu

Zulu is a dynamic risk scoring engine for web based content. For a given URL, Zulu will retrieve the content and apply a variety of checks in three different categories:

  • Content Checks – Inspection of page content to identify potentially malicious code in a variety of categories
  • URL Checks – Inspection of the full URL to identify malicious patterns and check the URL/FQDN/TLD against third party and Zscaler block lists
  • Host Checks – IP, DNS and netblock reputation checks

All algorithms generate both a risk score between 0-100 and a risk categorization (Low, Medium, High). Individual scores are then consolidated and weighted to calculate an overall page score and deliver a final categorization of Benign, Suspicious or Malicious based on overall page risk. Meta data for the page is also provided along with a history of past scans.

It should be noted that Zulu is entirely separate system from Zscaler's commercial cloud. Zulu often employs experimental checks being tested out that may be added to the Zscaler cloud in future. As such, results between Zulu and the Zscaler cloud may not be and are not intended to be consistent.
