Risk levelMedium

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

The website t413.com is a niche platform dedicated to providing free and community-driven 3D designs for FPV drones and accessories. It targets hobbyists and makers interested in 3D printing and FPV technology. The site has been operational since 2005, indicating a stable presence in its niche. The business model revolves around sharing designs and encouraging donations to support ongoing projects. Technically, the site uses standard web technologies with a custom or lightweight CMS and is hosted on a solar-powered infrastructure, reflecting a sustainable approach. Security posture is basic with HTTPS enabled but lacking advanced security headers and policies. Privacy and compliance documentation are absent, which is a gap for GDPR and general privacy best practices. Overall, the site is functional, safe, and trustworthy for its audience but would benefit from enhanced security and compliance measures.

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

7 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

  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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. 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';…

  4. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

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

t413.com operates in the technology sector focusing on FPV drone enthusiasts and 3D printing hobbyists. Its competitive advantage lies in free, high-quality 3D designs and active community engagement through social media and Discord. Revenue streams appear limited to donations, indicating a community-supported model rather than commercial sales. The site’s long domain age and consistent content delivery suggest a dedicated operator with a loyal user base. Partnerships or subsidiaries are not evident, and the site maintains a focused scope without extensive commercial expansion. Growth potential exists through enhanced marketing and formalization of business processes.

Security posture

The website maintains a basic security posture with HTTPS enabled and domain transfer protection. However, it lacks DNSSEC, security headers, and formal security policies such as incident response or vulnerability disclosure. No security.txt or contact channels for security incidents are provided. The absence of privacy and cookie policies also indicates compliance gaps. While no critical vulnerabilities are evident from the content, the site would benefit from implementing standard security best practices to protect user data and improve trust.

Recommendations

  1. Enable DNSSEC to improve domain security and prevent DNS spoofing.
  2. Implement standard security headers including Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Publish privacy and cookie policies to enhance GDPR compliance and user trust.
  4. Add a security.txt file and contact channels for incident response and vulnerability reporting.
  5. Consider adding verified contact information to improve business credibility and user support.

Technical notes

Notes

The website uses a straightforward tech stack with HTML5, CSS3, JavaScript, and Font Awesome icons. It appears to be custom-built or uses a minimal CMS, with no heavy frameworks detected. Hosting is self-managed or via a solar-powered project, which may impact performance but aligns with sustainability goals. The site is mobile optimized with good navigation and content structure but lacks advanced SEO and accessibility features. There is no evidence of analytics or tracking scripts, indicating minimal data collection. Technical debt appears low but modernization opportunities exist in security and compliance implementations.
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.
