What's wrong with enterprise email?

Email has grown bigger than its origins

Email has been around nearly as long as the internet, and it was never designed as a secure method of communication. When you send an email, just like other internet data, it travels through multiple nodes. At any one of these nodes, a bad actor could be present. It could be at your mail server, the server of your recipient, or somewhere in the middle.

Misfires - more common than you think

It's not just bad actors you have to worry about when you click 'send'. The number one cause of email data exposure is human error - sending a sensitive email or document to the wrong person.

What the ICO says...

Encrypt emails and attachments

"Any email containing sensitive personal data (either in the body or as an unencrypted attachment) should be sent encrypted."

Record data collection audit logs

"If you operate automated processing systems (any IT database), you must keep logs for the following processing actions: Collection, alteration, consultation, disclosure (including transfers), combination, erasure."
- ICO, 2023

Recall emails as soon as you can

"[in the event of a data breach] act quickly. Try to recall the email as soon as possible. If you can’t recall it, contact the person who received it and ask them to delete it."
- ICO, 2023
