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

12 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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: SMB

      Port 445 (SMB) is publicly accessible - SMB - Windows file sharing, high risk

      What to do: Immediately restrict access to SMB 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: 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

  4. 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

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

SEMSEA operates in the digital marketing sector, specifically targeting businesses that require expert Google Ads management. Their business model revolves around providing tailored advertising strategies, campaign setup, ongoing optimization, and strategic consulting. The company leverages certifications like Google Partner and partnerships with analytics providers to enhance credibility. Their market position is that of a specialized, experienced agency with a focus on data-driven and transparent client relationships. The presence of multiple case studies and client logos indicates a healthy client base and successful project delivery. The company targets small to medium-sized enterprises primarily in Austria but also has a related presence in Hamburg, Germany. Their ecosystem includes partnerships with analytics and lead generation service providers.

Security posture

The website employs HTTPS with modern TLS protocols (TLS 1.3 and 1.2) and has no known SSL vulnerabilities. Security headers are present but could be enhanced by enabling HSTS and DNSSEC. The site uses cookie consent management to comply with GDPR, and no sensitive data exposure or vulnerable libraries were detected. However, the absence of DMARC records and security.txt files indicates room for improvement in email security and vulnerability disclosure. The use of third-party tracking and marketing scripts is managed with user consent, reflecting a mature privacy approach. Incident response and security policy documentation are not publicly found, which is common for marketing agencies but could be improved for transparency.

Recommendations

  1. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload to strengthen HTTPS enforcement.
  2. Implement DNSSEC to protect DNS queries from spoofing and improve domain security.
  3. Add CAA DNS records to restrict which certificate authorities can issue certificates for the domain.
  4. Enable OCSP stapling on the web server to improve SSL certificate revocation checking performance and security.
  5. Publish a security.txt file to provide a clear channel for vulnerability disclosure and incident reporting.

Notes

The website is built on WordPress 6.8.1 using Elementor and Elementor Pro for page building, supplemented by Jet Engine and Borlabs Cookie for enhanced functionality and privacy compliance. Hosting is provided by kasserver.com with Apache server software. The site uses modern JavaScript libraries including jQuery and integrates multiple marketing and analytics tools such as Google Tag Manager, Facebook Pixel, Piwik PRO, and Fraud Blocker Tracker. Performance is moderate with room for optimization, but mobile responsiveness and accessibility are excellent. SEO is well implemented with comprehensive meta tags, Open Graph data, and structured JSON-LD schema. The technical stack is modern and well maintained, supporting a professional and user-friendly digital presence.
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.
