Name: Security Engine
Brand: Pitbull

The core of mail security

Pitbull Security Engine is the first line of defense for inbound and outbound email traffic. Rspamd integration combines Bayesian scoring, greylisting, SPF/DKIM/DMARC checks and phishing patterns in a single policy engine. ClamAV and Avast REST layers detect malicious attachments and macro risks.

Who is it for?

Hosting providers, data centers and enterprise IT teams deploy Security Engine as a centralized security layer in front of cPanel, DirectAdmin or Postfix servers — reducing server CPU/RAM load while improving filter quality.
