Continuous monitoring
When your website breaks, goes offline, or shows a "Not Secure" warning, you lose trust and you lose sales. Most business owners don't find out their site is down until a frustrated customer tells them. We change that with automated website monitoring.
Three steps and Defendly is standing guard.
Paste your URL. No plugins, no installs, nothing added to your site's code.
Uptime, SSL, and malware checks run automatically, every minute of every day.
The moment something looks wrong, we email or text you — before your customers notice.
We check your website every single minute. If it goes offline, we immediately send you an email or text message so you can get it fixed before you lose customers.
Forgetting to renew your SSL certificate makes your site look dangerous to visitors. We track your certificates and remind you weeks before they expire.
Small businesses are targets for hackers too. We scan your pages daily to ensure malicious code hasn't been added to your site without your knowledge.
No confusing charts or developer jargon. Every Monday, we send you a simple email telling you exactly how your website performed and if anything needs your attention.
We only hear about problems after they're already fixed.
Marit H.
Owner, coffee roastery
Our checkout page went down on a Saturday morning and we had a text within a minute. Fixed before we lost the weekend rush.
Anders B.
Owner, plumbing service
I didn't even know SSL certificates expired until Defendly warned me three weeks early. One less thing to worry about.

Owner, boutique salon
The weekly email is the only report I actually read. Plain English, five minutes, done.

No installs, plugins, or code changes. Just add your website's address and Defendly starts checking it from the outside, the same way a visitor would.
We confirm the outage with a second check to rule out a fluke, then immediately email and text you so you can act before customers notice.
Yes. Our Business plan covers multiple sites under one account, with alerts and reports kept separate for each one.
We scan your public pages daily for injected scripts, spam links, and known malware signatures — the kind of tampering that can get a site blacklisted by search engines and browsers.
You can run a full website scan with no credit card required. From there, every plan comes with a no-risk trial period before billing starts.
