I wanted to know how small businesses and early-stage startups actually hold up when it comes to basic web security. Not the Fortune 500 companies with dedicated security teams—the local shops, the new SaaS products, the businesses built by people who are experts at their thing but not necessarily at cybersecurity.
So I ran security scans on 120 different websites, all with explicit permission from their owners. I used a combination of automated tools and manual checks, looking at the same things an attacker would look at when deciding whether a site is an easy target.
The results were worse than I expected.
The Numbers
68% of the websites were missing at least one critical HTTP security header. These headers are basic protections that tell browsers how to handle your site securely. Without them, you're leaving doors open that should be closed.
42% of the sites were broadcasting detailed information about their server software, framework versions, and tech stack. This is like putting a sign on your front door that says "Here's exactly what tools you'd need to break in."
23% had TLS configuration problems. Either they were using outdated SSL versions, weak cipher suites, or had certificate issues. In 2026, this is table stakes—and nearly a quarter of sites I looked at were getting it wrong.
These Weren't Edge Cases
What surprised me wasn't that I found problems. Security is hard, and everyone makes mistakes. What surprised me was how fundamental these issues were.
We're not talking about sophisticated vulnerabilities that require expert knowledge to find and fix. We're talking about:
- Missing Content-Security-Policy headers
- No X-Frame-Options protection (makes clickjacking trivial)
- Servers announcing their exact version numbers to anyone who asks
- SSL certificates that were about to expire or already had
These are the security equivalent of leaving your car unlocked. It doesn't mean someone will definitely steal it, but you're making their job a lot easier if they try.
Why Does This Keep Happening?
After talking to the website owners, a pattern emerged. Most of them treated security as a one-time checkbox during the initial site launch. They got the site live, maybe ran it through some basic checklist their developer provided, and then moved on to running their actual business.
I get it. Security doesn't generate revenue. It doesn't bring in customers. When you're trying to grow a business, spending time on security feels like it's taking away from things that actually matter.
The problem is that the web doesn't stand still. New vulnerabilities are discovered constantly. Best practices evolve. That "secure" configuration from two years ago might not cut it anymore.
And nobody's checking back in on these sites until something goes wrong.
What You Can Do About It
You don't need to become a security expert. You don't need to hire one either, at least not right away. Here's what I'd recommend:
First, know where you stand. Run your site through a security scanner. There are free ones out there, including the one we built at Securiu. It takes less than a minute and will flag the most obvious issues.
Second, check your security headers. Sites like securityheaders.com will grade you and tell you exactly what's missing. Most of these can be fixed by adding a few lines to your server configuration.
Third, keep your software updated. If you're running WordPress, Shopify, or any other platform—keep it current. Same goes for plugins and themes. Most attacks exploit known vulnerabilities that already have patches available.
Fourth, set a calendar reminder. Once a quarter, take 30 minutes to review your site's security. Check for updates, run another scan, look at your SSL certificate expiration date. Make it routine.
The Bigger Picture
The whole point of this research wasn't to shame anyone or prove how insecure small business sites are. It was to show how common these oversights are—and how fixable they are.
Most of the issues I found could be resolved in an afternoon by someone who knows what they're looking for. That's the gap we're trying to fill with Securiu: making ongoing security accessible for businesses that don't have dedicated IT teams or massive budgets.
Security doesn't have to be complicated or expensive. It just needs to be consistent.
