What's wrong with enterprise email?

Email has grown bigger than its origins

Email has been around nearly as long as the internet - but it was never designed to be secure. 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.

Email: internal and external risks

Misfires - more common than you think

It’s not just bad actors you need to worry about when you click ‘send’. The leading cause of email data exposure is human error - sending sensitive information to the wrong person. It’s easy to do in an age of autocomplete - but businesses and individuals can face fines, and the ICO regularly enforces against organisations of all sizes.

What the ICO says...

Read the ICO (Information Commissioner's Office) advice on email data protection.

Encrypt emails and attachments

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

- ICO, 2023

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

What is enterprise email security?

Many organisations focus on inbound security - spam filters, malware scanners – but outbound email protection is just as critical.

Outbound email security protects sensitive data sent from an organisation via email. That includes information that could harm the organisation if intercepted - financial data, customer details, or intellectual property.
