Email is still one of the most common ways attackers get into an organization. As we noted in our MSP post below, the FBI's Internet Crime Complaint Center logged more than $20.8 billion in reported losses in 2025, and business email compromise alone accounted for roughly $3 billion of that total. ![Reported cybercrime losses in 2026](https://blog.mdaemon.com/hs-fs/hubfs/inline-1-cybercrime-losses-2025.jpg?width=1200&height=510&name=inline-1-cybercrime-losses-2025.jpg) To help you get started, we've gathered our most useful recent posts on email security.
