When it comes to sending emails, security is everything but straightforward. As one of the oldest systems that are still widely used across the Internet, email fundamentally lacks any kind of consideration for security or privacy.
Over the years, there have been many solutions proposed and deployed to address this shortcoming, most of which are transparent to end users.Red Sift’s OnDMARC assists with setting up the three core technologies widely used to “add” security to email: SPF, DKIM, and DMARC. These technologies work hand-in-hand to protect both the company and their customers from phishing and malicious email.
Technical solutions, however, are never enough.

Not only is it often prohibitively expensive to run such a crucial service internally, staying on top of critical updates without compromising the availability of email requires a dedicated team.
Even then, there are a number of great products out there that are loved by development, marketing, and commercial teams for their ease of use and distinctive features. Instead of flat-out banning cloud services, it is useful to consider what real threats they pose to our company. We need to develop an intuition as to where things may go wrong, and how they will affect operations when they do.
