As email remains the top threat vector for cyberattacks, Enterprises, and smaller email security providers must stay ahead of the curve. 

Large mailbox providers like Gmail, Microsoft, and Yahoo have successfully kept their users’ emails secure. 

Here are five tricks that you  can learn from them:

1. Real-time blocklists during the SMTP session
   Big mailbox providers use industry blocklists, like Abusix, to drop known bots and spammers during the SMTP session and prevent them from reaching their users’ inboxes; similarly, they can create lists of known bad senders and domains that badger their users and have high complaint rates. Enterprise email security can use these same industry blocklists via query for the quickest response and easiest configuration and similarly reinforce the list with their local blocklist.
2. SPF, DKIM, and DMARC Authentication
   Big mailbox providers also use SPF, DKIM, and DMARC for authentication and threat protection to detect and block phishing and malware attacks. Enterprise email security can implement the same solutions to safeguard users’ mailboxes and protect their brands.
3. Layered Filtering
   Large mailbox providers have many layers of filtering and each layer can be used to provide metadata for Machine Learning algorithms to improve detection or to reinforce earlier decisions.  
4. Two-Factor Authentication
   Big mailbox providers provide two-factor authentication to add an extra layer of security to user accounts. Enterprise email security should migrate all users to two-factor authentication to protect their email accounts.
5. Continuous Monitoring
   Big mailbox providers continuously monitor their systems for any unusual activity or signs of compromise from their accounts. They learn from any abuses of their systems and put additional measures in place to prevent similar issues from happening again in the future.

By adopting these tricks, you can improve their overall email security posture and better protect your users’ emails from email threats.
