59/100

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

Heidrick & Struggles International, Inc. operates a leading global retained executive search and leadership consulting firm. The company specializes in executive search, leadership development, on-demand talent, and organizational culture consulting, serving a broad range of industries with a strong market position. The website reflects a mature digital presence with professional design, clear navigation, and comprehensive content targeting corporate clients seeking leadership solutions. Technically, the site uses Sitecore CMS, Microsoft IIS hosting, and integrates Coveo search and OneTrust cookie consent, indicating a modern and scalable infrastructure. However, a critical security gap exists as the site lacks HTTPS/SSL encryption, exposing users to potential risks. Privacy compliance is well addressed with clear policies and consent mechanisms. Overall, the site is professional and credible but urgently requires SSL implementation to meet security best practices.

Scanned

3 of 7 checks could not complete. The site may be unreachable or blocking automated scans, so the results below cover only what could be checked. Try a rescan later.

NIS2 and GDPR posture

NIS2 outside view

GDPR outside view
Not assessed

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

1 finding rated critical or high. Fix these first.

  1. 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

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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 strong market position as a top retained executive search firm with enterprise scale and global reach. Its business model focuses on high-value professional services including executive search, leadership coaching, and organizational consulting. The firm targets corporate clients and executives across multiple industries, leveraging data-driven insights and integrated services. Recognitions such as Forbes World's Best Management Consulting Firm 2024 enhance its credibility. The digital ecosystem includes partner portals for clients and candidates, investor relations, and media communications, supporting a comprehensive engagement strategy. The firm demonstrates strong branding consistency and trust signals, positioning it well for continued growth and client acquisition.

Security posture

The website's security posture is weak due to the absence of HTTPS/SSL, no support for modern TLS protocols, and lack of HSTS. While some security headers like Content Security Policy and X-Content-Type-Options are present, critical protections are missing. Cookies are set with Secure and HttpOnly flags, which is positive, but without HTTPS, these protections are ineffective. No evidence of vulnerability disclosures or incident response contacts was found. The lack of encryption poses significant risks to data confidentiality and user trust. Immediate remediation is required to implement SSL certificates and modern security configurations to protect users and comply with industry standards.

Recommendations

  1. Implement a valid SSL/TLS certificate and enable HTTPS site-wide immediately.
  2. Configure HSTS with includeSubDomains and preload to enforce secure connections.
  3. Upgrade server to support TLS 1.2 and TLS 1.3 protocols and disable insecure protocols.
  4. Enhance security headers by adding X-Frame-Options, Referrer-Policy, and Content-Security-Policy directives.
  5. Establish a vulnerability disclosure policy and publish security contact information.
  6. Regularly audit and update third-party libraries and dependencies to mitigate vulnerabilities.
  7. Improve performance monitoring and optimize load times for better user experience.
  8. Maintain and update privacy and cookie policies to reflect evolving regulations.

Technical notes

Notes

The website is built on a robust technical stack including Microsoft IIS 10.0, Sitecore CMS, and Azure hosting inferred from DNS and TXT records. It integrates Coveo for site search and analytics, OneTrust for cookie consent management, and Google Tag Manager for tracking. The frontend uses Vue.js components for dynamic UI elements. The site is well-structured with SEO-friendly meta tags and Open Graph data. However, the lack of HTTPS severely undermines the security of the infrastructure. Performance data was not available, but the presence of modern frameworks and CDN usage suggests potential for good performance. Accessibility and mobile optimization appear well implemented based on semantic HTML and ARIA attributes. Technical debt is minimal but security misconfigurations present operational 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.
