My Email Communications Security Assessment (MECSA)

CONFIDENTIAL DELIVERY

(5.0/5)

Your e-mail provider protects your messages (sent/received) from eavesdroppers, using encryption. It applies the latest technologies available, assuring the identity of the parties with which interacts.

PHISHING AND IDENTITY THEFT

(3.5/5)

Your e-mail provider prevents the reception of messages from not legitimate servers. It also takes measures to avoid unauthorized servers to send emails from accounts of your domain. With these actions it is drastically reducing the probability of receiving (or generating) impersonation and/or Phishing attacks.

INTEGRITY OF MESSAGES

(3.5/5)

Your e-mail provider can identify messages that have been modified or intercepted during its delivery phase (from the sender MTA to the recipient MTA).
