Blocklists Overview

A blocklist contains known untrusted IP addresses, Hashes, Email addresses, and URLs. Access to such endpoints is blocked to avoid content downloads.

Blocklists support the following types:

  • Anti-malware—IP address, URL, file hash, and e-mail sender
  • SecIntel—IP address and domain.
Note:

  • For IP addresses and URLs, the web GUI performs basic syntax checks to validate the entries.

  • A hash is a unique signature for a file that is generated by an algorithm. You can add custom blocklists hashes for filtering in a TXT file with each entry on a single line. You can only have one running file with a maximum of 15,000 file hashes.
