Risk levelMedium

0–100, higher is better. How it is calculated

Onscreen is a small Greek technology service provider specializing in Joomla CMS support, website development, and e-commerce solutions. The company targets businesses and individuals in Greece seeking professional Joomla-based web services. The website demonstrates a good level of technical maturity with Joomla CMS, Bootstrap framework, and responsive design, but lacks some advanced technical and security features. Security posture is moderate with HTTPS enabled and cookie consent implemented, but missing important security headers and privacy policy documents. Overall, the website is functional and professional but would benefit from enhanced compliance and security practices to improve trust and user confidence.

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

Onscreen operates in a niche market focused on Joomla CMS services within Greece. Its business model revolves around service provision including support, development, and training. The company appears to have a consistent brand presence and targets a specialized audience. There is no evidence of partnerships or subsidiaries. The lack of publicly available contact emails or phone numbers may limit direct customer engagement. The company could improve market positioning by publishing comprehensive privacy and security policies and expanding contact options.

Security posture

The website uses HTTPS, which is a fundamental security requirement. However, it lacks critical security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security, which are important to mitigate common web vulnerabilities. No incident response or security contact information is provided, and no vulnerability disclosure or security.txt files are found. The absence of privacy policy and terms of service documents indicates compliance gaps, particularly regarding GDPR. The security posture is adequate but requires improvements to meet best practices and regulatory requirements.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  2. Implement essential security headers to enhance protection against common web attacks.
  3. Add explicit contact information including company emails and phone numbers for better customer and security incident communication.
  4. Regularly update Joomla CMS and extensions to mitigate vulnerabilities.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.

Technical notes

Notes

The website is built on Joomla CMS using the Helix Ultimate framework, Bootstrap, and Font Awesome for styling and icons. Google Fonts are used for typography. The site is mobile responsive and has a professional design. Performance is moderate with no evident heavy scripts or trackers. Accessibility features are basic but present. SEO optimization is good with proper meta tags and descriptions. No advanced analytics or marketing tools are detected. Hosting provider details are not explicitly found in the HTML content. Overall, the technical infrastructure is solid for a small service provider but could benefit from modernization and enhanced security configurations.
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.
