Tools for Compliance Monitoring on Business Emails (Data Breach Alerts)

One of the most financially damaging cyber threats in 2025 is the compromise of business emails, which accounted for 73% of all cyber attacks in 2024. While 66% of these phishing attacks targeted organisational resources like employee credentials and fake billing documents, the remaining 34% targeted personal information, especially financial data.

In March 2025, these attacks have seen a 35% increase, making email compliance crucial.

Email compliance refers to the adherence to laws, regulations, and best practices when sending emails, especially during marketing campaigns, to protect user data and prevent spam. With email compliance tools, you can ensure that you are adhering to all these recommendations and laws, while also following your organisation’s internal policies.

In this blog, we will take you through the 6 top email compliance tools for preventing data breaches on your business emails.
