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

5 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.

    • 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Facebook, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  2. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

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.

Business context

Business profile

Jeremy Keith's Adactio.com occupies a niche market position as a respected personal brand in web development. The site leverages a content-driven approach with multiple feeds and syndication channels, fostering community engagement. Revenue streams appear limited to affiliate links and possibly book sales, with no advertising or tracking scripts detected, indicating a privacy-conscious approach. The site integrates with various social and community platforms, enhancing reach and influence. The long domain age and consistent content updates demonstrate stability and ongoing relevance. Partnerships and projects linked on the site further reinforce the brand's credibility and network within the technology sector.

Security posture

The website enforces HTTPS and uses a clientTransferProhibited domain status, indicating basic domain security hygiene. However, DNSSEC is not enabled, and no explicit security headers were detected in the HTML content, representing areas for improvement. The site does not publish a security policy or vulnerability disclosure page, nor does it provide incident response contact information. No analytics or tracking scripts reduce privacy risks but also limit visibility into user behavior. Overall, the security posture is moderate with good foundational practices but lacking in advanced security controls and transparency.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Implement and publish a privacy policy and cookie consent mechanism to improve GDPR compliance.
  3. Add standard security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options.
  4. Publish a security policy and vulnerability disclosure page to improve transparency and incident response readiness.
  5. Consider integrating privacy-respecting analytics to gain insights while maintaining user trust.

Technical notes

Notes

The website is built with a custom or static site approach, leveraging modern web standards and progressive enhancement techniques. It uses service workers for offline support and integrates IndieAuth and Micropub protocols for authentication and content publishing. The site is hosted with a reputable registrar and DNS provider, ensuring reliable domain management. Performance is fast with good mobile optimization and accessibility features. There is no evidence of a traditional CMS or third-party analytics, indicating a lightweight and privacy-focused technical infrastructure. Opportunities exist to improve security headers and implement DNSSEC for enhanced protection.
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.
