Priority findings

6 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 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: 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

  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

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Weak SPF Policy

      SPF record has permissive policy allowing any server to send email

      What to do: Use -all or ~all qualifier for better email security

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 positions itself in the niche market of sustainable digital product design, serving clients in sectors such as energy and possibly others. Their business model is service-oriented, focusing on digital product design and development with sustainability as a core value. The website showcases key projects and clients, indicating a portfolio-driven approach. There is no evidence of direct e-commerce or affiliate marketing. The lack of detailed business registration or contact information limits deeper business intelligence insights. The company appears to maintain privacy in domain registration, which is common for small digital agencies.

Security posture

The website uses HTTPS and modern web technologies but lacks visible security headers such as Content-Security-Policy or X-Frame-Options. No security or incident response policies are found, and no contact channels for security issues are provided. The absence of privacy and cookie policies indicates potential compliance gaps with GDPR and other regulations. No vulnerabilities or exposed sensitive data were detected in the provided content. The security score is moderate, with recommendations to improve header implementation, privacy disclosures, and contact transparency.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve GDPR compliance.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Provide clear contact information including emails and phone numbers for general and security inquiries.
  4. Conduct regular security audits of third-party scripts and libraries to mitigate vulnerabilities.
  5. Enhance transparency by including incident response and vulnerability disclosure information.

Technical notes

Notes

The website employs modern web fonts (IBM Plex Serif and Sans), SVG animations, and cloud-hosted images via Cloudinary, indicating a modern and performant technical stack. The site is mobile optimized with responsive design elements. SEO is supported by proper meta tags and Open Graph data. However, no CMS or hosting provider information is evident. Performance appears fast based on Google Speed Index references. Accessibility is basic but present. The site lacks visible analytics or tracking scripts, suggesting minimal user tracking.
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.
