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

WhatIsMyBrowser.com is a specialized technology website providing detailed browser detection, user agent parsing, and troubleshooting guides for general internet users and technical support teams. Founded in 2010, it offers a niche service that helps users identify their browser versions, settings, and system information to resolve internet-related issues efficiently. The site also provides developer APIs and tools to integrate browser detection into other applications. Technically, the website employs modern web standards including HTML5, CSS3, JavaScript, and structured data (JSON-LD) to enhance SEO and accessibility. Hosting appears to be via Hetzner Online GmbH, with good mobile optimization and moderate performance. Security posture is solid with HTTPS enforced and no exposed sensitive data, though improvements could be made by adding security headers and explicit cookie consent mechanisms. The absence of WHOIS data reduces domain trust slightly, but the website’s content quality, social media presence, and affiliate transparency support its legitimacy. Overall, the site is a reliable resource for browser-related information and developer tools.

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

5 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 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';…

  2. 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

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Twitter

      What to do: Document all third-party data sharing in your privacy policy

  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

The website occupies a niche market position focused on browser detection and user agent parsing services, targeting both end-users and developers. Its business model includes providing free informational content and guides, supplemented by affiliate marketing partnerships, notably with NordVPN. The company maintains a consistent brand and professional content quality, with a small team led by founder Brett Harris. The lack of direct contact emails or phone numbers suggests a lean operational model relying on web forms for communication. The partnership ecosystem includes VPN providers, enhancing user privacy offerings. Growth potential lies in expanding API services and developer tools. The absence of detailed WHOIS data and registrant information is a minor concern but does not detract significantly from the business credibility given the site's longevity and content depth.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS and no visible exposure of sensitive data. However, the lack of security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement to mitigate common web vulnerabilities. No explicit incident response or vulnerability disclosure information is provided, which could hinder rapid response to security issues. Cookie consent mechanisms are absent despite cookie usage, potentially impacting GDPR compliance. The site uses third-party scripts for affiliate marketing and detection, which should be monitored for security risks. Overall, the security culture appears adequate but could benefit from formalized policies and transparency enhancements.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Add a clear cookie consent banner and detailed cookie policy to improve privacy compliance.
  3. Publish a security.txt file and provide explicit incident response contact information to facilitate vulnerability reporting.
  4. Enhance contact options by providing verified company emails or phone numbers for better user trust and support.
  5. Investigate and clarify WHOIS domain registration details to improve domain trustworthiness and transparency.

Technical notes

Notes

The website uses a modern technology stack with HTML5, CSS3, JavaScript, and JSON-LD structured data to optimize SEO and accessibility. Hosting is provided by Hetzner Online GmbH, inferred from the IP address. Performance is moderate with good mobile responsiveness. The site includes affiliate marketing scripts and third-party detection scripts, which are integrated without visible errors. There is no detected CMS, suggesting a custom or static site architecture. Technical debt appears low, but the absence of security headers and cookie consent mechanisms indicates areas for modernization. Overall, the technical infrastructure supports the business goals effectively with room for security and privacy enhancements.
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.
