# Postini

**Canonical:** https://apis.io/providers/postini/  
**APIs profiled:** 0

Postini was an email security and message-management company founded in 1999, providing hosted spam and virus filtering, email archiving, encryption, and web security for businesses. Google acquired Postini in 2007 (roughly $625M) and folded its capabilities into Google Apps (now Google Workspace); the standalone Postini service was discontinued and customers were transitioned to Google Apps by around 2012. The postini.com domain is now Google-owned and redirects to google.com. This profile is retained as a historical portfolio-lead record; the company has no live, standalone API surface, developer portal, or documentation to enrich.
