Machine learning has helped Gmail achieve more than 99% accuracy in spam detection, and with the following new protections, Google is able to reduce users’ exposure to threats by confidently rejecting hundreds of millions of additional messages every day.
New Built-In Gmail Protections to Combat Malware in Attachments
With new built-in defenses against ransomware and polymorphic malware, Gmail now blocks millions of additional emails that can harm users. Google classifies new threats by combining thousands of spam, malware and ransomware signals with attachment heuristics (emails that could be threats based on signals) and sender signatures (already marked malware).
New warnings for unintended external replies, to prevent data loss
Powered by Google’s machine learning, this new Gmail feature helps protect against forged email messages, impersonation, as well as common errors when sending email to the wrong contacts.
This feature empowers G Suite users when responding to emails sent from outside of their organization and not in their contacts. Now, if you try to reply to someone outside of the organization, you’ll receive a quick warning to make sure you intended to send that email.
