I find the root cause of big data breaches rather fascinating. It’s often one small oversight that leads to snowballing disaster.

Think of a major breach you’ve read about. What’s the one single biggest preventative measure that could have stopped or at least minimized the damage?

For the business owners here, what’s the one thing you would never compromise on when it comes to protect your customer/product/sales data, etc?

Email is very often the initial attack vector because its so simple! Threat actors need little expertise or experience to begin exploiting it. And once they’re in, it can snowball quickly.

Protecting your email, through dns record policies (like DMARC, SPF, DKIM), suspicious email analysis, and MFA/strong passwords is one of the main things we recommend for Shopify stores

Real story. I returned an Amazon order on a local post office the other day. Right after, a scam reminder popped up on my phone. It had my full name and was asking me to deposit for an unclaimed package. And it was from a foreign postal carrier. I hate to live in a world where data breach is way too common.

I wonder what if this happens to a small business? Say a customer comes back asking why their information was breached after making a purchase online? Anybody looking into cyber or data breach insurance?
