As answered by people managing PowerDMARC and InboxStack.
PowerDMARC's answer
The idea for PowerDMARC came from noticing how businesses, both small and large, fall victim to very basic cyber attacks and fail to protect themselves from impersonation, email spoofing, and phishing, and are not able to afford basic cybersecurity protection due to the high cost and complexity of setup. The vulnerability we protect from is not allowing hackers to send emails from your exact domain name itself. Imagine if someone sends an email from your company’s domain name - how would anyone understand that this email is not real?
Many organizations across the globe lose billions of dollars every day due to hackers spoofing their own exact domains due to existing vulnerabilities in email protocols. The solutions that existed in the market were very expensive, inaccessible for many businesses, and very hard to set up and configure. The idea was to make domain and email protection very simple and provide it at a super affordable price for all organizations, with no technical knowledge requirement.
