THE LATEST THOUGHTS FROM THE FOUNDER

A SNEAK PEEK…
“You don’t need to panic about what you can’t see. You do want to make sure you’re handling the things you can control.”
You’re going about your day, maybe checking email or reviewing a report, and then you hear something on the news or from a colleague. “There’s a new security issue out there. Companies are being hit before anyone even knew it existed.” That’s usually when the question comes up: how can something be exploited if nobody even knew it was broken?
It’s a fair question, and honestly, it can feel a little unsettling. Most business owners assume that as long as software companies are doing their job, issues should be found and fixed before they become a problem. It would be nice if it worked that way every time.
The reality is a little different, a “zero-day vulnerability” is simply a flaw in software or hardware that no one knows about yet. The company that made the product doesn’t know it’s there, the people using it don’t know it’s there, your IT support team doesn’t know it’s there. That means there have been zero days to fix it, because it hasn’t been discovered.
Now imagine someone with bad intentions stumbles across that flaw first. They can quietly take advantage of it because there’s no patch, no warning, and no built-in protection specifically designed for it yet. That’s where the risk comes in. Not because the system is neglected, but because it’s an unknown.
There is a better version of this situation, though. Sometimes a security researcher, someone who’s actively looking for problems so they can be fixed, discovers the issue first. They report it responsibly, the vendor creates a fix, and updates start rolling out. In those cases, the system works the way we all hope it will.
Unfortunately, that’s not always how it goes. There are situations where attackers find these vulnerabilities and quietly exploit them for days, weeks, or longer before anyone realizes what’s happening. That’s when you tend to hear about it in the news, after the damage has already started.
So where does that leave your business? It’s important to understand that you can do everything “right” and still not be completely immune to something like this. There is no way to guarantee that every unknown vulnerability has been found and patched. Anyone who tells you otherwise is probably oversimplifying things.
What you can do is reduce your risk and limit the impact, this is where some of the basics really earn their keep. Keeping your systems updated matters because most known vulnerabilities are fixed through those updates. Having good security tools in place helps because they focus on behavior, not just known threats. Even if a specific vulnerability is new, unusual activity often follows it, and that can still be caught and stopped by software like a good Endpoint Detection And Response (EDR).
It’s a bit like locking your doors and having an alarm system. You can’t prevent someone from discovering a new way to pick a lock, but you can make it much harder for them to get far once they try. The goal isn’t to eliminate all possible risk, because that’s not realistic. The goal is to be thoughtful, consistent, and prepared so that when something unexpected happens, it doesn’t turn into a crisis.
Most of the time, the companies that run into serious trouble aren’t the ones hit by a brand new, never-before-seen issue. It’s the ones that missed updates, skipped basic protections, or didn’t have a response plan in place.
So if you’re thinking about zero-day vulnerabilities, the real takeaway is this. You don’t need to panic about what you can’t see. You do want to make sure you’re handling the things you can control. Are your systems being updated regularly? Do you have something watching for unusual behavior, not just known threats? If something did happen, would you know how to respond? Those are the questions that matter.
If you’re not sure how you’d answer them, it might be worth taking a little time to step back and look at your setup. Not to overhaul everything overnight, just to get a clear picture of where you stand.
That’s how I see it, anyway, and I’d enjoy hearing how you see it. None of this is a sales pitch. It’s just the kind of thing I’d talk through with you if we were sitting across the table. If it raised a question, or you think I have it wrong, I want to hear about it.
My door is always open. Whether you want to talk this through or just say hello, you can reach me anytime.
