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

Files-conversion.com is a free online file conversion service primarily focused on video file formats but also supporting audio, image, archive, document, and other file types. The website is part of Dan's Tools brand, offering a suite of utility tools for general internet users. The business model relies on advertising revenue, supported by a comprehensive consent management platform to comply with privacy regulations such as GDPR. The site is accessible, well-structured, and provides a good user experience with multiple language options and a broad range of conversion services. Technically, the site uses a modern tech stack including jQuery, Bootstrap, Google Fonts, and plupload for file uploads. It integrates Google Analytics and Adsense for tracking and monetization. Hosting appears to be via AWS CloudFront CDN. Performance and mobile optimization are moderate to good, though accessibility features are basic. Security posture is adequate with HTTPS enforced and cookie consent implemented, but lacks advanced security headers and explicit security policies. The security posture shows no critical vulnerabilities or malware but could improve with better header implementation and form security. WHOIS data is missing, which raises concerns about domain legitimacy and trustworthiness, though the website content and brand presence suggest a legitimate operation. No direct company contact emails or phone numbers are provided, limiting business credibility somewhat. Overall, the website is a functional, moderately secure, and privacy-conscious free utility service with room for improvement in security practices and business 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

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. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

  3. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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

The website targets general internet users needing free file conversion tools, positioning itself as a niche utility under the Dan's Tools brand. Its competitive advantage lies in offering a wide variety of file conversion services in multiple languages, supported by advertising revenue. The business model is freemium with optional registration for premium features. The partnership ecosystem includes advertising networks like Google Adsense, Ezoic, and programmatic vendors such as VDX.tv and Quantcast. Growth indicators include multiple related domains in different languages and integration of social media for user engagement. However, lack of direct contact information and missing WHOIS data may impact trust and limit enterprise partnerships.

Security posture

The site enforces HTTPS and implements a cookie consent mechanism compliant with GDPR, indicating a baseline security and privacy awareness. However, it lacks explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options, which are recommended best practices. Forms for login and registration exist but no explicit CSRF or input validation mechanisms are visible. No incident response or security policy pages are found, and no security contact channels are provided. The missing WHOIS data reduces domain trustworthiness. Overall, the security maturity is moderate with no critical vulnerabilities detected but several areas for improvement to enhance protection and compliance.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response page with clear contact channels for vulnerability reporting.
  3. Enhance form security by adding CSRF tokens and server-side input validation to prevent injection attacks.
  4. Verify and update WHOIS domain registration information to improve domain legitimacy and trust.
  5. Provide clear company contact information including verified emails and phone numbers to increase business credibility.

Technical notes

Notes

The website uses a standard and widely supported technology stack with jQuery, Bootstrap 3.4.1, Font Awesome, and Google Fonts. File upload is handled by plupload, a robust client-side uploader. Analytics and advertising are integrated via Google Analytics, Adsense, and Ezoic, with programmatic ad vendors for monetization. Hosting appears to leverage AWS CloudFront CDN for content delivery. The site is mobile responsive and SEO optimized with proper meta tags. Performance is moderate, with some room for optimization. Accessibility features are basic but present. No CMS is detected, suggesting a custom or static site architecture. Technical risks include outdated Bootstrap version and lack of advanced security headers.
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.
