Check your website’s NIS2 exposure in minutes

Guard reads the public web, DNS, TLS, email-authentication and privacy controls of any domain and shows what an auditor, insurer or attacker sees first. Free scan, no account.

Public information only. Nothing on the site is exploited or changed.

Daily rescans of every area in the scan, an email when something material changes, and a dated history you can export.

Directory figures count the latest report per domain in the public directory.

What Guard checks

Five areas, all read from signals any visitor can see. The report scores each one, ranks findings by risk and cites the standard behind each finding, so you know what to fix first and can show why.

Email authentication

Whether mail sent in your name can be spoofed, and where it is delivered.

SPF · DKIM · DMARC · MX

RFC 7208 · RFC 6376 · RFC 9989 · RFC 8461

Transport and web security

Certificate and protocol configuration, browser-side protections and known-vulnerability indicators.

SSL/TLS · security headers · vulnerability checks

OWASP ASVS 5.0 · Mozilla Server Side TLS · RFC 8996 · MITRE CWE

Privacy and compliance posture

An indicative readout of the public controls GDPR and NIS2 expect. Evidence for an assessment, not a certification.

GDPR · NIS2 · privacy policy · cookie consent

NIS2 Art. 21 · Implementing Regulation 2024/2690 · GDPR Arts. 7, 12–13, 32 · ePrivacy Art. 5(3)

Technology and quality

What the site runs on and how it performs for visitors and search engines.

Technology stack · performance · mobile · SEO

External exposure

Everything the site pulls in or points to beyond its own domain.

External domains · subdomains · third-party trackers

A scan is a snapshot. Monitoring keeps watch.

Certificates are renewed, DNS records edited, plugins and trackers added. Each change can quietly reopen an exposure you already fixed. Monitoring rescans your domain every day, tells you when something material changes and keeps the history you need when an auditor, customer or insurer asks how long a control has been in place.
