Hey everyone! Big news: the PCI DSS 4.0 deadline is coming up fast! This time, DMARC is becoming mandatory for *anyone* handling credit card data. I know, it sounds like a pain, but trust me, it's *super* important. Phishing is still a massive threat, unfortunately. 
So, what's the deal with DMARC? Think of it as a bouncer for your inbox. It helps block those sneaky, fake emails. Seriously, without DMARC, your company's basically an open invitation for cybercriminals. 
A lot of folks are probably thinking, "Nah, doesn't apply to me." Nope! Even small businesses *have* to implement DMARC. It's a must-do! 
Now, I'm curious: Do you guys already have DMARC set up? And if you do, what tools are you using? Let's share some insights!
