Overview

Welcome to Sublime

Introduction

Sublime is a customizable email security platform that gives IT and security teams full control over their email environment, enabling them to enforce custom, tailored rules for phishing defense, DLP, and compliance.

At its core, Sublime is a rules engine that takes in arbitrary input (like an email message from Office 365 or a reported phish), evaluates it using a powerful query language, and then takes any number of actions. Below is an example of a simple rule:

name: "File sharing link with BEC subject"
type: "rule"
severity: "medium"
source: |
  type.inbound
  and any(body.links, .href_url.domain.domain in $free_file_hosts)
  and iregex_search(subject.subject, '\bw2\b', 'w2s', 'immediately', 'urgent')

Rules can use data from a variety of sources such as:

  • static information from the email message
  • external data like whois or domain blacklists
  • custom organizational information like Google or Office365 groups
  • arbitrary NLP or other machine learning models
  • historical data such as past correspondence with the sender or the sender's organization
  • and more
