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

Teachers Lead Tech is an educational platform focused on providing creative computer science curriculum and professional development workshops for K-8 teachers. The platform is recognized internationally, having won the World Summit Awards in 2022 and being a finalist at MIT Solve's Global Challenge. Their offerings include integrated CS lessons, AI fundamentals, and digital literacy, targeting educators aiming to enhance their classrooms with technology. The website is built on modern technologies including Astro framework and hosted on Hostinger, with analytics via Google Analytics and Facebook Pixel. The site is well-designed, mobile-optimized, and provides clear navigation and content relevant to its audience. Security posture is good with HTTPS enabled, though security headers are lacking. Privacy and cookie policies exist but are basic and lack strong GDPR compliance indicators. The domain WHOIS data is missing, raising concerns about domain legitimacy, but the professional content and awards suggest a legitimate operation. The site announced cessation of services as of February 29, 2024, advising users to save data accordingly.

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 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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

  3. 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 SSL Key Length

      SSL certificate uses 384-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

  4. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Weak SPF Policy

      SPF record has permissive policy allowing any server to send email

      What to do: Use -all or ~all qualifier for better email security

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 business operates in the education sector, focusing on K-8 computer science teaching resources and teacher professional development. It leverages partnerships with organizations like MIT Solve and Google.org, enhancing credibility and market positioning. The business model centers on providing curriculum packages and workshops, likely generating revenue through subscriptions or school partnerships. The target customers are K-8 educators and schools seeking to integrate computer science creatively. The company maintains a small size with a focused niche. The presence of partner domains and external links to educational summits indicates an ecosystem approach. Growth indicators include awards and active content updates, though the announced service termination suggests strategic shifts or closure.

Security posture

The website employs HTTPS with a valid SSL certificate, ensuring encrypted communications. However, it lacks important security headers such as Content-Security-Policy, X-Frame-Options, and HSTS, which could improve protection against common web attacks. No vulnerabilities or exposed sensitive data were detected in the HTML content. Forms appear secure but no explicit security or incident response policies are published. Privacy compliance is basic, with cookie consent mechanisms present but limited GDPR indicators. The absence of WHOIS registrant data is a risk factor for trust and domain legitimacy. Overall, the security posture is moderate but could be enhanced by implementing recommended headers and publishing security policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and HSTS to enhance web security.
  2. Publish clear terms of service and incident response policies to improve transparency and compliance.
  3. Enhance privacy policy to explicitly address GDPR compliance and data retention practices.
  4. Obtain and publish WHOIS registrant information or ensure domain registration details are transparent to improve trust.
  5. Maintain regular security audits and vulnerability assessments to ensure ongoing protection.

Technical notes

Notes

The website is built using the Astro framework and hosted on Hostinger, indicating a modern and scalable infrastructure. It uses Google Fonts for typography and integrates Google Analytics and Facebook Pixel for user tracking and marketing analytics. The site is mobile-optimized with responsive design and good navigation clarity. Performance is moderate, with no major issues detected in the HTML structure. The CMS is Hostinger Website Builder, which provides ease of content management but may limit advanced customization. There is room for improvement in accessibility features and SEO optimization to enhance reach and usability.
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.
