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

CV-Library LTD operates one of the UK's largest independent job boards, offering a comprehensive platform for job seekers and recruiters. Founded in 2000, it provides services including job search, CV registration, job alerts, career advice, and a company directory. The website targets UK job seekers and recruitment professionals, maintaining a strong market position with over 123,000 live vacancies and more than 10,000 companies registered. Technically, the website employs modern JavaScript frameworks, Google Tag Manager, Amplitude analytics, and OneTrust for cookie consent management. It is well-optimized for mobile devices and accessibility, with structured data enhancing SEO. The site uses HTTPS with good SSL configuration, though some security headers could be improved. From a security perspective, the site follows best practices such as HTTPS enforcement and secure form handling. No vulnerabilities or exposed sensitive data were detected. Privacy compliance is strong, with clear privacy and cookie policies and GDPR adherence. However, WHOIS data is unavailable due to domain naming rules errors, which slightly impacts trust but does not detract from the site's professionalism. Overall, CV-Library presents a secure, professional, and user-friendly platform with a solid business model and market presence. Strategic improvements in security headers and WHOIS transparency could further enhance trust and compliance.

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 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';…

  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

CV-Library is positioned as a leading UK job board with a large user base and extensive job listings. Its business model revolves around connecting job seekers with employers and recruiters, generating revenue through job advertising and CV database access. The company leverages partnerships with related job sites to expand its market reach. Its competitive advantage lies in its large database, user-friendly interface, and comprehensive career resources. The company targets a broad demographic of UK job seekers and recruitment agencies, with growth indicators visible in its extensive job listings and active social media presence.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no visible exposure of sensitive data. Use of third-party analytics and marketing tools is balanced with privacy compliance mechanisms such as OneTrust cookie consent. However, the absence of some security headers like Content-Security-Policy and X-Frame-Options suggests room for improvement. The lack of a published security policy or incident response contact reduces transparency. No vulnerabilities or malware indicators were found, indicating a stable security environment suitable for its business operations.

Recommendations

  1. Implement Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options headers to enhance security.
  2. Publish a formal security policy and incident response contact information to improve transparency and trust.
  3. Investigate and resolve the WHOIS domain naming rules error to improve domain registration transparency.
  4. Regularly audit third-party scripts and tracking tools for security and privacy compliance.
  5. Enhance data retention policy disclosures related to analytics and user data.

Technical notes

Notes

The website uses a modern JavaScript-heavy front end with asynchronous loading of analytics and tracking scripts. It employs Google Tag Manager, Amplitude for experimentation and analytics, and OneTrust for cookie consent management. The site is mobile-optimized with responsive design and accessibility considerations. Performance is moderate, with some deferred script loading to improve page speed. No CMS is explicitly detected. Hosting provider details are not evident from the HTML. The technical implementation supports a professional user experience but could benefit from additional security header configurations and performance optimizations.
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.
