Priority findings

4 findings rated critical or high. Fix these first.

  1. 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

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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 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

  • 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
  • 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

ZetaOffice targets organizations seeking flexible office suite solutions with no vendor lock-in, emphasizing integration capabilities and performance optimization. Their open source approach and availability of SDKs foster community engagement and customization. The company maintains a small but professional presence with clear contact information and customer logos, indicating early market traction. Partnerships with allotropia.de reinforce credibility. Revenue likely stems from paid CDN usage and support packages. The company is positioned as a specialized technology provider in the office productivity software sector.

Security posture

The website enforces HTTPS and domain transfer protection but lacks DNSSEC and common security headers, which are recommended to mitigate DNS spoofing and clickjacking risks. No incident response or security policy information is published, limiting transparency. The absence of cookie consent mechanisms may pose GDPR compliance risks. Analytics usage is minimal and privacy-conscious. Overall, the security maturity is moderate but would benefit from enhanced DNS security, security headers, and published policies to improve trust and compliance.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add a cookie consent banner or mechanism to comply with GDPR and other privacy regulations.
  4. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  5. Regularly audit third-party scripts and dependencies to avoid vulnerable libraries and ensure secure form handling.

Technical notes

Notes

The website uses a clean, modern HTML5 and CSS structure with Bootstrap icons and custom styles. It integrates plausible.io for privacy-friendly analytics and offers downloadable desktop applications via CDN links. The domain is registered with a reputable registrar and uses bunny.net for CDN services. Performance is moderate with good mobile optimization and clear navigation. No CMS or heavy frameworks detected, indicating a lightweight custom implementation. Technical risks include missing DNSSEC and security headers, which should be addressed to enhance security posture.
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.
