How it works

Identify and remediate phishing gaps
  1. (M365 users) Run a free phishing retro scan in minutes to identify active threats that have already evaded existing security controls over the past 14 days and are currently sitting in your inboxes. (Gmail users) Request a free phishing risk assessment to identify the phishing threats that are evading your existing security controls, as they’re being delivered.
  2. Review the results of your scan or assessment to better understand the frequency and types of attacks that are bypassing your current defenses.
  3. Deploy Cloudflare’s email security service either inline (as MX), via API, or in multi-mode (hybrid of both).
