About DMARC Defender
Why I Built DMARC Defender
I had to deploy DMARC as a security engineer at a few companies, and I thought the process was needlessly complicated and expensive. I did not enjoy having to sit through a mandatory sales call so they could maximize pricing, or being charged an SSO-Tax. Then once on the platform, you're met a with a bulky, slow, and brittle app.
I built DMARC Defender to be a simple, affordable way to understand authentication issues and fix them quickly.
Background
I have about 20 years of software and security experience. I'm also the founder of csper.io . I previously worked on security and infrastructure at organizations including Yahoo! and MongoDB.
Philosophy
I believe deliverability tools should be simple, affordable, and honest. My goal is to help growing teams take control of sender reputation, email authentication, and email security without hidden costs or enterprise friction.
