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

Skooli is an established online tutoring platform headquartered in Toronto, Canada, providing instant access to certified and professional educators across a broad range of subjects and grade levels. The platform targets students, parents, schools, and tutors, offering personalized tutoring solutions via a proprietary online classroom. Skooli emphasizes quality by vetting tutors with teaching licenses and advanced degrees, positioning itself as a trusted and industry-recognized service in the education sector. Technically, the website employs modern web technologies including JavaScript frameworks, third-party integrations like Google Tag Manager and Zendesk, and supports mobile responsiveness. The infrastructure supports real-time communication via socket.io and secure payment processing through Stripe. While the site is well-designed and performant, some security headers are missing, and cookie consent mechanisms are not explicitly implemented. From a security perspective, the site enforces HTTPS and includes anti-clickjacking scripts, with secure login and registration forms. However, the absence of visible security headers and lack of published security policies or incident response contacts indicate areas for improvement. The WHOIS data is unavailable, which slightly reduces trust but does not detract significantly given the professional presentation and contact transparency. Overall, Skooli presents a credible, professional, and user-friendly online tutoring service with a solid technical foundation. Strategic enhancements in security headers, privacy compliance, and transparency around incident response would further strengthen its security posture and user trust.

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

3 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.

    • 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

  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

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

Skooli operates in the competitive online education market, focusing on high-quality tutoring by certified educators. Its business model is a marketplace connecting students and parents with tutors, supplemented by district and school partnerships. Revenue likely derives from tutoring session fees and institutional contracts. The company targets a broad demographic including K-12 students, university students, parents, and educational institutions. The presence of multiple related domains for signups, classrooms, chat, and support indicates a mature ecosystem. Testimonials and certifications enhance market credibility. Growth potential exists in expanding subject offerings and geographic reach. The company maintains active social media engagement and uses modern marketing tools, supporting brand visibility and customer acquisition.

Security posture

Skooli demonstrates a moderate to strong security posture with mandatory HTTPS, secure form handling, and background checks for tutors. The site includes anti-clickjacking measures but lacks several recommended HTTP security headers such as Content Security Policy and HSTS. No vulnerabilities or exposed sensitive data were detected in the HTML content. Privacy compliance is good with a comprehensive privacy policy and GDPR indicators, but cookie consent mechanisms are absent. Incident response and vulnerability disclosure information are not publicly available, which could hinder rapid response to security events. Overall, the security maturity is adequate for the business type but could be improved by adopting additional best practices and transparency.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Add a visible cookie consent banner or mechanism to comply fully with privacy regulations and improve user transparency.
  3. Publish a dedicated security policy and incident response contact information to build trust and facilitate vulnerability reporting.
  4. Conduct regular security audits and update third-party libraries to mitigate potential vulnerabilities.
  5. Enhance accessibility features to improve usability for all users and comply with accessibility standards.

Technical notes

Notes

The website uses a modern technology stack with JavaScript libraries such as jQuery, Axios, Socket.io for real-time communication, and CryptoJS for cryptographic functions. It integrates Google Tag Manager for analytics and Zendesk for customer support. The site is built with Bootstrap for responsive design and uses Typekit for custom fonts. Payment processing is handled via Stripe with a live publishable key present. Performance is moderate with deferred script loading and CDN usage for assets. The site is mobile optimized and SEO friendly with proper meta tags and Open Graph data. However, the absence of a CMS or hosting provider information limits deeper infrastructure insights. Overall, the technical implementation supports a robust and scalable online tutoring platform.
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.
