Guardr monitors security headers, SSL, DNS, exposed API keys in JavaScript bundles, and uptime across all your client sites — and tells you what's broken before your clients do.
One dashboard, 30-second setup, no more manual checks. Try a free scan below.
Get your security score in 3 simple steps
Just type your website URL. No signup, no installation, no code changes required.
SSL, headers, DNS, exposed files, JS secrets, cookies — every attack surface a real attacker would check. Results in seconds.
See your A–F grade with plain-English fixes for every issue. Sign up and we'll alert you the moment anything changes.
So you don't have to.
Set it up once. We'll guard it — so you can focus on your work, not your worries.
Your site shows a browser security warning
An expired or misconfigured certificate causes browsers to block visitors entirely — showing a full-page warning before they can reach your site.
Visitors see content you never wrote
Without the right protections, outsiders can modify what visitors see on your site — without touching your code.
Visitors land on a fake copy of your site
A compromised domain can silently redirect your traffic to a lookalike page you don't control.
Private files are open to anyone online
Config files, credentials and admin pages accidentally left public are trivial for attackers to find.
A user's account gets taken over
Poorly configured login sessions can be stolen — especially when users are on public WiFi or shared networks.
API keys are leaking from your JavaScript bundles
OpenAI, Stripe, AWS, and Anthropic keys embedded in client-side code are publicly readable. Guardr scans your live bundles and flags them before attackers do.
Continuous security scans. Uptime monitoring. Clear remediation steps.
We check your site around the clock from 3 global regions. Downtime or security gap — you'll know first, without false alarms.
Not just problems — solutions. Step-by-step guides to fix every issue.
Problems get flagged instantly. You decide how and when to be notified.
Guardr scales with your roster. Start on the free plan and upgrade as your client list grows — without paying for sites you don't have yet. Save 20% with annual billing.

Security configs break silently — a missing header, HSTS gets disabled, an accidentally exposed .env file. You won't notice until customers complain or Google flags your site. Guardr catches these gaps the moment they appear.
Even a few minutes of downtime during peak hours can cost e-commerce sites thousands in lost sales and damage customer trust. Guardr monitors uptime around the clock from 3 independent global regions — so when we alert you, it's confirmed, not a false alarm.
TLS/SSL settings (HTTPS, HSTS, redirects, certificate expiry), security headers (CSP, X-Frame-Options, Referrer-Policy), DNS security (DNSSEC, CAA records), exposed files (.git, .env, phpinfo), cookie security, and client-side JavaScript bundles scanned for exposed API keys (OpenAI, Anthropic, Stripe, AWS, Google AI, Supabase). All checks are external — we only see what attackers see.
No — and that's intentional. Guardr monitors your public-facing configuration and uptime, your first line of defense. We don't do penetration testing or code analysis, but we catch the misconfigs that make attacks easier.
Free tools give you a snapshot. Guardr watches continuously, alerts you when something changes, tracks your score over time and tells you exactly how to fix each issue. Plus uptime monitoring — one dashboard for everything.
No. Guardr scans externally — no agents, no code changes, no server access. Enter your domain and we handle the rest.
Yes. You ship fast and move on to the next thing. Guardr watches what you've shipped — if a header breaks, a file gets exposed or your site goes down, you'll know immediately. Fix it once, then forget about it.
You can't manually check every client site every day. Guardr does it for you. Monitor all your sites from one dashboard, get alerted when something breaks and send branded reports that show clients you're keeping them secure. It builds trust and justifies your retainer.
Free forever for one site — no credit card. Upgrade when you're managing more than one client and need alerts, grade history and weekly reports.
