What do they do I hear many people thinking? In the ever-changing world of digital communications, email security has become a top priority for businesses of all sizes. Microsoft recently took an important step by making inbound SMTP DANE (DNS-based Authentication of Named Entities) with DNSSEC (Domain Name System Security Extensions) generally available to customers of Exchange Online, part of Microsoft 365. But what exactly does this mean and why is it so important for our customers and SMBs? We put this briefly #superlogically.

What is SMTP DANE and DNSSEC?

SMTP DANE is a protocol that helps secure e-mail through the use of DNSSEC. DNSSEC is a set of extensions for DNS that ensure the integrity and authenticity of DNS data. Together, these technologies ensure that emails are delivered securely and that the identity of the sender and receiver is verified.

Why is this important?

1. Increased Security: Using SMTP DANE and DNSSEC significantly reduces the risk of man-in-the-middle attacks and e-mail spoofing. This is especially critical for industries with high security requirements, such as government agencies and financial institutions.
2. Reliability: With DNSSEC, companies can be sure that the DNS data they receive is authentic and has not been manipulated. This increases the reliability of e-mail communications.
3. Protection of Sensitive Information: For SMBs that frequently send sensitive information via e-mail, this extra layer of security provides peace of mind. It helps protect company data and customer information from unauthorized access.
4. Compliance: Many industries have strict regulations regarding data security. Implementing SMTP DANE and DNSSEC helps companies comply with these regulations and avoid potential fines and reputational damage.

What does this mean for our customers?
