Security threats are not optional to ignore
Every unprotected site is a liability for your visitors, your rankings, and your sending reputation.
Your site has no SSL
Browsers now flag every HTTP site as "Not Secure". Visitors leave. Google penalises your rankings. It takes minutes to fix, yet thousands of sites still don't have it.
You don't know if your site has been compromised
Most malware infections are silent. Your site keeps loading while it serves spam, steals visitor data, or participates in attacks you will only discover when you're blacklisted.
Your IP or domain is on a spam blacklist
A blacklisted IP means your emails don't reach clients and your sending reputation takes months to recover.
