Domain encryption and S/MIME: Not all certificates are created equal

Encrypting emails is the best way to protect your company’s communications and keep sensitive data from being illegally accessed. Many companies have understood this and therefore use encryption solutions. But compliance-based requirements and legal requirements such as the General Data Protection Regulation (GDPR) also contribute to the spread of email encryption solutions: Since 25 May 2018, the GDPR obliges companies to sign and encrypt emails that contain personal data and to perform transport encryption.

Sender Reputation and Email Security – Part 1: Authenticated Received Chain (ARC)

Procedures for checking sender reputation have existed for some time. These provide an effective way to detect fake sender domains and thus prevent phishing attacks. Although they are easy to implement and do not require expensive tools, many companies do not apply them – and thus fail to secure their organization in the best possible way. Furthermore, they fall behind in direct comparison with criminals, because they are also constantly improving their setup.

In our series of articles on sender reputation, you’ll learn how each method works and how they can help you protect you and your organization from phishing with fake senders and other cyberattacks, and optimize your email security. 

Part 1 focuses on the latest method that can be used as part of sender reputation checks: Authenticated Received Chain (ARC).
