Site showed 'SSL certificate invalid' warning — was it a hack or did the cert just expire?

Customers are calling: 'Your site has a red warning, is it a virus?' I checked, and the browser says 'SSL certificate invalid site not secure.' I was scared it was a hack, but the IT manager said 'the certificate expired.' Which one is it actually?

What does SSL certificate mean? How is it different from HTTPS? I'm currently using a 'Let's Encrypt' certificate. What is this thing? Should I switch to a paid cert? Are all certs the same?

is certificate renewal automatic? doesn't my hosting company provide support? we got an expiring soon warning but nobody notified us. how do i set up alerts?

right now: check my cert in cPanel (expiration date), enable renewal. problem solved, no extra cost after that.

note: I wrote this based on my own experience, it might not apply to everyone.

Here's how it went for us. When making a decision, first look at what data you have on hand.

I can't fully agree with this. Don't hesitate to ask; those who don't ask always pay more.

Proven by experience.

I have a question. Security isn't absolute; it's about making attacks not worth the effort.

Just leaving this note, it might be useful.

Three different views emerged, they all complement each other. When we decide without measuring we always end up in the same place.

Hasty decisions become decisions you have to fix six months later. honestly this is my opinion I'm not claiming it's absolute truth.

The answer above hits the nail on the head. Your time to detect an issue directly determines its cost.

Just because everyone does it doesn't mean it's right.

There's a trap here let me mention it. If it's your first time, start small; scaling comes later.

Correct me if I'm wrong.

Don't miss this: The harder it is to reverse a decision, the slower you should make it.

I'm also curious if anyone does it differently.

I've been down this road, let me tell you. Processes without records never improve, because you don't know what to fix.

Of course, it varies if your situation is different.

My question might sound amateurish, sorry about that. Hasty decisions become decisions you have to fix six months later.

Dont hesitate to ask; those who dont ask always pay more. If I were you, Id go this route.

I was thinking the same thing. honestly most incidents start with a leaked password, not a vulnerability.

This is my opinion, Im not claiming its absolute truth.

Let me summarize the topic, since several different answers were given. Forgotten test environments are more often the entry point than live systems.

Correct me if I'm wrong.

Thanks for writing this, that's the right way. Forgotten test environments are more often the entry point than live systems.

I'd say don't rush. Your time to detect an issue directly determines its cost.

If you post the result here, it will help others too.

I have no experience with ssl certificate error, so I'm asking. Payment information changes are never verified through the channel they came from.

Mistakes made on the ssl certificate error side are usually reversible but expensive.

Hope this helps.
