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

Kelly Services Inc. is a global leader in staffing and workforce solutions, connecting job seekers with meaningful employment opportunities and providing companies with expert talent solutions. The company operates a comprehensive website with a strong global presence, offering services such as temporary staffing, managed services, and consulting. The website is professionally designed, well-branded, and targets both job seekers and employers effectively. Technically, the site leverages HubSpot CMS and marketing tools, Cloudflare for CDN, and includes modern JavaScript libraries. However, the SSL certificate is currently invalid, and no modern TLS protocols are enabled, which significantly impacts the security posture. Privacy and cookie policies are present and include consent mechanisms, indicating good privacy compliance. Contact information is clearly provided, including phone numbers and social media links. Overall, the website is credible and trustworthy but requires urgent SSL and TLS configuration fixes to improve security.

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. GDPR outside view

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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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"

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

Kelly Services holds a strong market position as an industry leader in staffing and workforce solutions with a long history dating back to 1946. The company operates globally with multiple country-specific domains and specialty brands such as KellyOCG and Kelly Education. Their business model focuses on connecting talent with employers through various staffing and outsourcing services. The website reflects a mature digital marketing strategy using HubSpot and Google Tag Manager, with tracking and bot detection tools in place. The company targets a broad audience including job seekers and corporate clients, emphasizing workforce resilience and innovation. Investor relations and corporate governance information are publicly available, supporting transparency and trust.

Security posture

The website implements several important security headers such as HSTS, Content-Security-Policy, and X-Content-Type-Options, which are positive indicators of security awareness. However, the SSL certificate is invalid or missing, and no TLS protocols are enabled, which is a critical security flaw that exposes users to risks. There is no OCSP stapling or session resumption configured, and certificate transparency compliance is lacking. No direct evidence of incident response or vulnerability disclosure policies was found. The site uses bot detection and consent management tools, which help mitigate some risks. Overall, the security posture is currently weak due to SSL/TLS issues but shows signs of good security practices in other areas.

Recommendations

  1. Immediately fix the SSL certificate to ensure it is valid and trusted by browsers.
  2. Enable and configure modern TLS protocols (TLS 1.2 and TLS 1.3) to secure communications.
  3. Implement OCSP stapling and session resumption to improve SSL performance and security.
  4. Publish a clear vulnerability disclosure policy and incident response contact information.
  5. Continue enhancing privacy compliance and transparency to maintain user trust.
Technical notes

Notes

The website is built on the HubSpot CMS platform, utilizing jQuery 3.7.1 and various HubSpot marketing and analytics tools. It is hosted behind Cloudflare CDN, which provides performance and security benefits. The site includes Google Tag Manager and Cookiebot for tracking and consent management. Performance metrics were not available, but the site appears mobile optimized and accessible with good SEO practices. Some technical debt is indicated by the invalid SSL configuration and lack of modern TLS support, which should be prioritized for remediation to avoid user trust issues and security risks.
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.
