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

11 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • Critical

      Critical Service Exposed: PostgreSQL

      Port 5432 (PostgreSQL) is publicly accessible - PostgreSQL - Database server

      What to do: Immediately restrict access to PostgreSQL using firewall or VPN

      • NIS2 21(2)(e)

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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"

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 · found on this site
  • 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

Hart-Tech operates in the manufacturing sector, focusing on B2B services for metal heat treatment. Their competitive advantage lies in patented technologies and academic partnerships, enabling them to offer innovative surface engineering solutions. The company’s revenue streams likely come from service contracts with industrial clients requiring specialized metal processing. The website reflects a medium-sized enterprise with a clear brand identity and consistent messaging. Social media presence on Facebook, Instagram, and LinkedIn supports marketing and customer engagement. The absence of terms of service and explicit security policies suggests areas for improvement in formalizing business and compliance documentation.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, DNSSEC, and a consent management platform ensuring GDPR compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the site lacks explicit security policies and incident response contacts, which are important for transparency and readiness. The use of third-party scripts like Google Analytics and Usercentrics is managed with consent, reducing privacy risks. Recommendations include adding security headers such as Content-Security-Policy and X-Frame-Options, and publishing a security policy or incident response information to enhance trust and compliance.

Recommendations

  1. Implement additional HTTP security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to harden site security.
  2. Publish a dedicated security policy page and provide incident response contact information to improve transparency and readiness.
  3. Regularly audit and update third-party scripts and plugins to mitigate vulnerabilities.
  4. Add a terms of service page to formalize user agreements and legal protections.
  5. Enhance data retention disclosures related to analytics and marketing tools for full GDPR compliance.

Technical notes

Notes

The website is built on a modern WordPress CMS with Elementor page builder, leveraging popular libraries such as jQuery and Swiper.js for UI components. SEO is well addressed with Yoast SEO plugin and proper meta tags including Open Graph and JSON-LD structured data. Performance is moderate with asynchronous loading of scripts and lazy loading of images. Accessibility features are implemented via WP Accessibility plugin, providing contrast and font size toggles. The site is mobile optimized and uses a consent management platform for GDPR compliance. Hosting provider details are not explicit, but DNSSEC and HTTPS indicate a secure infrastructure. Overall, the technical implementation supports a professional and compliant online presence with room for incremental security enhancements.
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.
