CHECK IF YOU HAVE SECURE EMAIL
See if your email supports TLS encryption to secure your messages over the internet
We love spam musubi, but hate SPAM emails. We won’t save any email addresses entered here.
HOW WE CHECK IF AN EMAIL IS SECURE
When you enter an email in the Secure Email Checker, we look to see if the email server supports inbound Transport Layer Security (TLS) encryption.
If the email server supports TLS encryption, that means any message you send to that email address can’t be snooped and is protected in transit.
If the email server supports TLS encryption, that means any message you send to that email address can’t be snooped and is protected in transit.
When you enter an email, we check the first three MX records with the highest priority. Some email providers use multiple MX records tied to servers with different levels of TLS support.
If all MX records show the same priority, we randomly select three. If the results show MX records with the same priority, then run the check a few times to improve the accuracy of results.
How does TLS make email secure?
- Not all email is created equal.
- From the time a message leaves your inbox, makes its way across the internet, and gets to your recipient’s inbox, it can be intercepted or read unless it’s secured.
- The National Institute of Standards and Technology (NIST) sets the standards for protecting email by advising use of Transport Layer Security (TLS).
- When both the sender and recipient's email service uses TLS, messages are secure while in transit.
- But not all email providers are capable of receiving a message encrypted with TLS, which results in a message being delivered in cleartext that anyone can read.
- It’s estimated only 80% of email uses TLS, which means 2 out of 10 emails sent can be stolen or read by cyber criminals.
- Utilizing an email encryption provider like Paubox can solve that problem and meet regulatory requirements (like HIPAA).
