This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

9 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The business operates on a software licensing model targeting developers and teams requiring robust form validation solutions. Its competitive advantage lies in its zero-dependency architecture, broad framework support, and extensive validator collection. The presence of notable customers such as universities and government agencies enhances credibility. The company maintains a focused product portfolio with no detected subsidiaries or parent companies. Growth potential is supported by continuous updates and integration with modern frameworks. The ecosystem includes open source contributions and related products by the same author, indicating a strategic approach to developer tools.

Security posture

The website enforces HTTPS and avoids exposing sensitive data, reflecting good baseline security practices. However, it lacks advanced security headers and published security policies or incident response procedures, which are important for trust and compliance. No vulnerabilities or deprecated libraries were detected in the frontend code. The absence of DNSSEC and limited WHOIS transparency are minor concerns. Overall, the security posture is solid but could be improved by formalizing security documentation and enhancing domain security measures.

Recommendations

  1. Implement DNSSEC to enhance domain name security and prevent DNS spoofing.
  2. Add comprehensive security headers such as Content-Security-Policy and Strict-Transport-Security.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  4. Introduce a cookie consent mechanism to comply with privacy regulations and improve user trust.
  5. Provide clear and accessible contact information including support and sales emails or phone numbers.

Technical notes

Notes

The website is built on a modern React-based framework (Next.js) with ES6 and TypeScript, ensuring maintainability and type safety. It leverages popular web fonts and icon libraries for a polished UI. Performance is optimized with preloading and deferred scripts. The site is mobile responsive and accessible, with good SEO metadata and Open Graph tags for social sharing. No CMS is detected, indicating a custom or static site approach. Hosting details are not explicit but DNS uses NS1 name servers. The technical stack is modern and well-implemented, with opportunities to enhance security headers and domain security.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
