Mailhardener

Mailhardener is a specialized, cloud-based email security and monitoring service designed to help organizations of all sizes fortify their email infrastructure against a range of threats, including fraud, spam, and impersonation. At its core, the software serves as a comprehensive suite for managing and enforcing modern email security standards, which are often complex and challenging to implement manually. Its primary purpose is to leverage existing protocols like SPF, DKIM, and DMARC to control which senders are authorized to use a domain, effectively blocking fraudulent actors. The service also plays a crucial role in securing email transport by offering hosting for MTA-STS policies and BIMI assets, which are essential for enabling encrypted communication and brand recognition. By actively monitoring all email traffic and providing security results, Mailhardener not only improves a domain's security posture but also significantly enhances the deliverability of legitimate emails, ensuring they are not mistakenly flagged as spam. The software offers a flexible and scalable tiered pricing structure to accommodate a wide range of users, from individuals to large enterprises.
