Priority findings

5 findings rated critical or high. Fix these first.

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

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • 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
    • High

      High-Risk Service Exposed: NetBIOS

      Port 139 (NetBIOS) is publicly accessible - NetBIOS - Windows file sharing

      What to do: Consider restricting access to NetBIOS or implementing strong authentication

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

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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

The company operates in the competitive digital marketing sector with a focus on SEO and Google Ads, targeting primarily Austrian and German-speaking markets. Its business model revolves around service delivery through consulting, campaign management, content creation, and training workshops. The presence of client testimonials and a strong online presence suggests a solid market position. Revenue streams likely include project-based fees, retainer contracts, and educational services. The company maintains partnerships and related domains to support multilingual and international clients. Growth indicators include active blog content, social media engagement, and continuous service expansion. Strategic observations highlight the importance of maintaining technical excellence and privacy compliance to sustain competitive advantage.

Security posture

The website exhibits a good security posture with mandatory HTTPS and support for modern TLS protocols. Security headers such as Strict-Transport-Security are present but not fully enabled, and OCSP stapling is missing, which are areas for improvement. The cookie consent mechanism is comprehensive, covering essential, marketing, statistics, and external media cookies with granular user control, supporting GDPR compliance. No vulnerable libraries or exposed sensitive data were found. However, the absence of a published security policy or incident response contact limits transparency. Overall, the security maturity is solid but could benefit from enhanced header configurations and formalized security documentation.

Recommendations

  1. Enable full HSTS with includeSubDomains and preload to enforce HTTPS across all subdomains.
  2. Implement OCSP stapling to improve SSL certificate revocation checking and reduce latency.
  3. Add additional security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web attacks.
  4. Publish a clear security policy and provide incident response contact information to improve transparency and trust.
  5. Regularly audit third-party scripts and cookie usage to ensure ongoing privacy compliance and minimize tracking risks.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including jQuery, Yoast SEO, and Borlabs Cookie for consent management. Hosting is provided by kasserver.com, with DNS and MX records consistent with the domain. Performance is fast with optimized images and preloading of fonts. The site is mobile responsive and accessible, with structured data implemented via JSON-LD for SEO enhancement. Analytics are implemented using Google Analytics and Matomo Tag Manager, integrated via Google Tag Manager. No technical debt or deprecated technologies were detected. Opportunities exist to improve security headers and implement OCSP stapling for better SSL performance and security.
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.
