Clear, non-alarmist guidance for real web vulnerabilities so your team can prioritize fixes confidently.
Expired Security Certificate Is Blocking Visitors and Breaking Trust
immediateYour website's security certificate has expired. Think of it like an ID badge with a past-due date — browsers check this badge every time someone visits, and when it's expired, they show a full-screen warning telling visitors your site is unsafe. Most people will leave immediately rather than click through.
Your Website's Security Certificate Isn't Trusted by Browsers
highYour server is using a self-signed security certificate — one that you (or your server) created yourself, rather than one issued by a trusted authority. Browsers treat this the same way they'd treat a badge someone printed at home: it might look official, but there's no independent body vouching for it. Visitors to your site will see a security warning, and some browsers may block access entirely.
