Sections not covered

Several console areas under Symantec Email Security in the source notes — What's New, Encryption, Data Protection, Video Tutorials, Dashboard and Reports, Users and Groups, Tools, Administration, Support, and Data usage — were present as headings but had no captured content. They're intentionally omitted here rather than filled in with guesses.

  • Data Loss Prevention (DLP) — Symantec DLP is covered separately under Data Loss Prevention → Symantec DLP, since it's a distinct product line from email security.
  • Cloud SWG — Symantec also offers a Secure Web Gateway (SWG): a security control that inspects and filters users' web traffic between their device and the internet. The source notes only capture this one-line definition, with no further configuration detail, so it doesn't warrant its own page or category yet.
