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 X-Frame-Options header

      Prevents clickjacking attacks

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

  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 Policy found

      GDPR requires clear information about cookie usage

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

    • 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: Google Analytics, Facebook, Twitter, LinkedIn, Cloudflare, Google APIs

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 company holds a significant market position as a large-scale provider of substitute and early childhood education staffing services, supported by a large active talent pool and numerous partnerships. Its business model focuses on connecting qualified educators with schools and centers, leveraging digital channels for recruitment and client engagement. The parent company Kelly Services provides corporate backing, enhancing credibility. The website's integration with multiple advertising and tracking platforms indicates a mature marketing ecosystem aimed at maximizing reach and conversion. The presence of testimonials and detailed resource sections further supports customer trust and engagement.

Security posture

The website demonstrates a solid security foundation with enforced HTTPS using modern TLS protocols, successful OCSP stapling, and strict DMARC policies to prevent email spoofing. Domain registration is well-protected against unauthorized changes. However, the absence of HSTS and DNSSEC represents areas for enhancement. No critical vulnerabilities or exposed sensitive data were detected. The cookie consent implementation aligns with privacy regulations, indicating good compliance culture. Incident response and explicit security policies are not publicly documented, suggesting an opportunity to improve transparency and readiness.

Recommendations

  1. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload to prevent protocol downgrade attacks.
  2. Implement DNSSEC to secure DNS resolution and prevent spoofing.
  3. Add CAA DNS records to restrict certificate issuance to authorized CAs.
  4. Improve certificate transparency compliance to enhance trust and detect mis-issuance.
  5. Publish explicit security and incident response policies to improve transparency and stakeholder confidence.

Technical notes

Notes

The website is built on HubSpot CMS, utilizing jQuery, Google Tag Manager, Cookiebot for consent management, and various JavaScript libraries for UI enhancements such as Splide.js and AOS. The site loads a large number of resources (139) and has a relatively slow load time (~15.7 seconds), indicating potential optimization opportunities. Mobile responsiveness and accessibility are well addressed, with proper ARIA labels and alt attributes. SEO is supported by comprehensive meta tags and Open Graph data. Hosting is managed by MarkMonitor Inc., a reputable provider specializing in domain protection. Overall, the technical stack is modern but could benefit from performance tuning to improve user experience.
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.
