Postini

Postini was a cloud-based security service that protected businesses from email threats like spam, viruses, and phishing. It acted as a filter, analyzing incoming and outgoing emails to prevent harmful content from reaching users and to ensure compliance with security policies. Integrated with email platforms such as Gmail and Google Workspace, Postini improved email security without requiring hardware or complex setup. In 2007, Google acquired Postini, enhancing its security offerings to better safeguard corporate communications in the cloud.
