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.

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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Contractor Jobs operates as an important entity within the UK recruitment sector, focusing on contract roles. Its business model revolves around providing a digital marketplace connecting contractors with employers and recruiters. The platform benefits from its association with CV-Library Ltd, a recognized player in the UK job board market, enhancing its market position and trustworthiness. The site leverages extensive analytics and marketing tools to optimize user engagement and recruitment outcomes. While direct contact information is not prominently displayed, the presence of privacy and cookie policies aligns with regulatory compliance. The absence of explicit security and incident response policies suggests areas for improvement. The platform's growth potential is supported by its comprehensive job listings and recruitment services, appealing to a broad contractor audience and recruiters seeking specialized talent.

Security posture

The website demonstrates a good security posture with enforced HTTPS and cookie consent mechanisms, indicating awareness of privacy regulations such as GDPR. However, the absence of security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces its defense-in-depth capabilities. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of published security policies or incident response contacts limits transparency and preparedness for security incidents. The WHOIS lookup failure is a concern but likely technical rather than malicious. Overall, the site maintains a moderate to strong security stance but would benefit from enhanced security headers and published security documentation to improve trust and compliance.

Recommendations

  1. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  3. Add a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance contact information availability to improve user trust and support accessibility.
  5. Regularly audit third-party scripts and tracking tools to ensure compliance with privacy regulations and minimize user tracking.

Technical notes

Notes

The website uses a modern technology stack with Google Analytics, Google Tag Manager, Bing UET, and custom JavaScript libraries for autocomplete and lazy loading. The site is mobile optimized with responsive design and accessibility features such as skip links and ARIA labels. Performance is moderate with deferred script loading and preloading of fonts and scripts. SEO is supported by meta tags, canonical links, and structured data in JSON-LD format for search engine indexing. The hosting provider is not explicitly identified, but the use of AWS API Gateway endpoints for analytics suggests cloud infrastructure. No CMS is explicitly detected. Overall, the technical implementation is solid with opportunities to improve security headers and incident response capabilities.
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.
