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. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

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 in the technology sector focusing on app development for Apple devices. It appears to be a small-scale operation without visible corporate structure or extensive partnerships. The business model is based on developing and publishing apps driven by internal needs and ideas. There is no evidence of revenue streams, certifications, or extensive marketing efforts. The website uses a WordPress theme from a third party, indicating reliance on common web infrastructure. The lack of social media presence or external business contacts limits visibility and growth potential. The company maintains a simple web presence with basic branding and moderate content quality.

Security posture

Security maturity is basic. The website uses HTTPS, which is mandatory, but does not implement common security headers such as Content-Security-Policy or X-Frame-Options. There are no visible privacy or cookie policies, nor any incident response or vulnerability disclosure information. No analytics or tracking scripts are detected, which reduces privacy risks but also limits business intelligence. The absence of direct contact emails or phone numbers reduces transparency. Overall, the security posture is functional but could be significantly improved by adding security headers, privacy documentation, and incident response contacts.

Recommendations

  1. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish comprehensive privacy and cookie policies to comply with GDPR and other privacy regulations and improve user trust.
  3. Add explicit vulnerability disclosure and incident response information to demonstrate security maturity and readiness.
  4. Provide direct contact information such as company email addresses and phone numbers to improve transparency and user confidence.
  5. Enhance accessibility features and SEO optimization to improve user experience and search engine visibility.

Technical notes

Notes

The website is built on WordPress 6.8.1 with a custom theme named Digital Nomad. It uses jQuery and standard JavaScript for UI enhancements. The site loads CSS and JS resources from its own domain and WordPress core. Performance is moderate with no evident optimization or CDN usage. Mobile responsiveness is good due to viewport meta tags and responsive CSS. Accessibility is basic with skip links and some ARIA attributes but lacks advanced features. SEO is basic with meta tags and canonical links but no structured data or Open Graph tags. No analytics or advertising scripts are present, indicating minimal tracking. The technical stack is standard for small WordPress sites but could benefit from modernization and security hardening.
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.
