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

synchrnzr.com represents an independent technical sound design consultancy and educational resource operated by David Font, with a focus on game audio production, integration, research, lecturing, and mentoring. The website showcases a professional portfolio of projects and collaborations with recognized partners in the gaming and education sectors. The business operates in a niche technology segment with a long-standing presence since 2000, supported by a domain registered since 2004. The target audience includes game developers, audio professionals, researchers, and students seeking expert sound design services and learning resources. Technically, the website employs modern web standards including HTML5, CSS3, JavaScript, Google Fonts, and Google Tag Manager for analytics. The site is mobile optimized with good SEO practices and structured data for organization branding. Hosting details are not explicit, but the domain registrar is reputable. Performance is moderate with no critical technical issues detected. Accessibility is basic but functional. From a security perspective, the site uses HTTPS and secure cookie flags, but lacks advanced security headers and DNSSEC. No forms or sensitive data inputs are present on the homepage, reducing attack surface. Privacy compliance is basic with presence of privacy and cookie policies but no explicit consent mechanisms or GDPR compliance indicators. No incident response or vulnerability disclosure information is provided, which could be improved. Overall, the website is trustworthy, professional, and content-rich with a solid business credibility score. Security posture is adequate but can be enhanced with additional headers and policies. Privacy compliance requires improvement to meet modern standards. The risk level is low, with recommendations focusing on strengthening security and privacy transparency.

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

3 findings rated critical or high. Fix these first.

  1. 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

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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

  • 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

synchrnzr operates as a small independent consultancy specializing in technical sound design and game audio. The business model centers on providing production, integration, research, lecturing, and mentoring services primarily to the gaming and educational sectors. The company leverages a strong portfolio of collaborations with known industry partners and educational institutions, enhancing its market positioning as a niche expert. Revenue streams likely derive from project contracts, educational offerings, and mentoring. The partnership ecosystem includes recognized entities such as Aulart, ENTI, and UPC. Growth indicators include ongoing projects and active educational content. The company maintains a focused target customer segment of game developers and audio professionals, with a reputation for quality and expertise.

Security posture

The current security maturity level is moderate. The website enforces HTTPS and uses secure cookie flags, which are positive indicators. However, the absence of DNSSEC, security headers (CSP, HSTS, X-Frame-Options), and explicit privacy consent mechanisms highlight compliance gaps. No incident response or security policy information is published, limiting transparency and readiness. No vulnerabilities or exposed sensitive data were detected. The site does not collect data via forms on the homepage, reducing risk. GDPR compliance is partial due to lack of consent mechanisms. Overall, the security culture appears basic but functional, with room for improvement in formal policies and technical controls.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options to mitigate common web attacks.
  3. Add a cookie consent banner or mechanism to comply with GDPR and improve privacy transparency.
  4. Publish a formal security policy and incident response contact information to improve trust and readiness.
  5. Consider creating a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website is built with modern web technologies including HTML5, CSS3, and JavaScript, leveraging Google Fonts and Google Tag Manager for enhanced user experience and analytics. The site is mobile optimized and uses structured data (JSON-LD) for SEO and branding. Hosting details are not explicit but the domain registrar is reputable. Performance is moderate with no broken elements detected. Accessibility is basic but functional. There is no detected CMS, indicating a custom or static site architecture. Technical risks are low but could be improved by adding security headers and enabling DNSSEC. The site is well-maintained with consistent branding and professional content.
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.
