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

7 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

    • 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

  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 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"

    • 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';…

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 company holds a strong market position in manufacturing and construction sectors with a broad portfolio of subsidiaries serving industrial building, concrete prefab systems, pools, and food markets. Their business model leverages vertical integration and diversification to mitigate risks and create synergies. The target audience includes B2B clients in construction and food sectors as well as job seekers. The group maintains active communication channels including social media and a dedicated job portal. Growth indicators include recent acquisitions and active project showcases. The partnership ecosystem is extensive with multiple related domains and subsidiaries. Strategic observations highlight a focus on sustainability (ESG) and innovation, positioning the group for continued expansion in European markets.

Security posture

The website enforces HTTPS and implements a cookie consent mechanism aligned with GDPR requirements, indicating a good baseline for privacy and security. However, the absence of explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options suggests room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of published security policies or incident response contacts limits transparency and readiness perception. Overall, the security maturity is moderate to good, suitable for a corporate website but could benefit from enhanced security controls and public disclosure of security practices.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response plan on the website.
  2. Add security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to improve protection against common web attacks.
  3. Create and publish a security.txt file to facilitate responsible vulnerability disclosure.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities or outdated components are present.

Technical notes

Notes

The website is built using standard modern web technologies including HTML5, CSS3, and JavaScript, with external libraries such as Font Awesome, Ion Icons, and Plyr for video playback. The site is hosted on a CDN infrastructure (sitemn.gr) which supports performance and availability. The site is multilingual with language switchers and alternate hreflang tags, supporting international visitors. SEO is basic but present with meta tags and structured navigation. Performance is moderate with some external dependencies. Mobile optimization is good with responsive design elements. Accessibility is basic and could be improved. No CMS or backend platform was explicitly detected. Overall, the technical infrastructure is solid but could benefit from enhanced SEO and accessibility improvements.
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.
