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

4 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 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

STL operates in the education sector providing a broad portfolio of over 500 courses focused on software training, professional development, and management skills. Their business model includes public scheduled courses, bespoke onsite training, and virtual classrooms, targeting corporate clients and individual professionals. The company leverages a strong working culture and innovation to maintain competitive advantage. Their client base includes major corporations such as Amazon, HSBC, and Volkswagen, indicating strong market penetration. STL uses digital marketing tools and analytics to optimize customer engagement and course offerings. The presence of multiple social media channels and trust signals supports brand credibility and customer acquisition. Growth indicators include active promotions, last-minute course offerings, and extensive post-training support.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and integration of Cloudflare Bot Management to mitigate automated threats. Cookie consent is managed via CookieYes with granular user controls, supporting GDPR compliance. Security best practices such as no exposed sensitive data and secure form handling are observed. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not confirmed and should be implemented to enhance protection against common web attacks. No incident response or vulnerability disclosure information is publicly available, which is a gap in transparency. Overall, the security maturity is good but can be improved with additional header configurations and published security policies.

Recommendations

  1. Implement and verify comprehensive security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy.
  2. Publish a clear security policy and incident response contact information to improve transparency and trust.
  3. Regularly audit and update CMS and third-party libraries to mitigate vulnerabilities.
  4. Enhance privacy compliance by documenting data retention policies and providing a vulnerability disclosure program.
  5. Maintain and promote trust indicators such as certifications and customer testimonials to strengthen market position.

Technical notes

Notes

The website uses a modern and well-supported technology stack including Bootstrap 5.3 for responsive design, jQuery for DOM manipulation, and Select2 for enhanced search functionality. Google Tag Manager and CookieYes are integrated for analytics and privacy compliance. Hosting is likely via Cloudflare, providing performance and security benefits. The site loads quickly and is optimized for mobile devices with good accessibility features. Structured data in JSON-LD format is implemented for SEO enhancement. Minor technical debt may exist in the form of missing explicit security headers and reliance on third-party scripts, which should be monitored. Overall, the technical infrastructure is robust and supports the business objectives effectively.
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.
