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

Springest B.V. operates a leading Dutch online platform specializing in the comparison and booking of educational courses, training, and personal development products. Founded in 2008 and headquartered in Utrecht, Netherlands, Springest serves both individual learners and organizations with a comprehensive catalog of over 101,000 offerings from more than 9,200 providers. The platform emphasizes user reviews, free information requests, and corporate learning solutions, positioning itself as a trusted marketplace in the education sector. Technically, the website employs a modern and performant infrastructure with technologies such as jQuery, Mixpanel analytics, and custom CSS/JS assets. The site is mobile-optimized, accessible, and SEO-friendly, providing an excellent user experience. Security measures include HTTPS enforcement, CSRF tokens, and a cookie consent mechanism, although formal security policies and incident response contacts are not publicly documented. The security posture is strong with no detected vulnerabilities or exposed sensitive data, but there is room for improvement in publishing explicit security policies and enhancing HTTP security headers. Privacy compliance is well addressed with GDPR-aligned policies and user consent mechanisms. Overall, the domain registration and WHOIS data align well with the business claims, supporting high legitimacy and trustworthiness. Strategic recommendations include formalizing security and incident response documentation, enhancing security headers, and maintaining vigilance on third-party scripts. These steps will further strengthen Springest's security posture and user trust while supporting its market leadership in educational services.

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. 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"

    • 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

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

Springest holds a strong market position as a comprehensive educational marketplace in the Netherlands, targeting both individual learners and corporate clients. Its business model revolves around aggregating and comparing a vast range of educational products, facilitating direct bookings, and leveraging user-generated reviews to build trust. Revenue streams likely include commissions from providers, subscription services, and corporate learning solutions (Springest Go). The company benefits from a broad partnership ecosystem with thousands of providers and multiple country-specific domains, indicating international expansion efforts. Growth indicators include a large course catalog, extensive user reviews, and active social media presence. The platform's focus on user experience, free information access, and corporate solutions positions it competitively in the education technology sector.

Security posture

Springest demonstrates a mature security posture with HTTPS enforced site-wide, CSRF protection in forms, and a comprehensive cookie consent mechanism aligned with GDPR requirements. No critical vulnerabilities or exposed sensitive data were detected in the analyzed content. However, the absence of a publicly available security policy and incident response contact points represents a compliance and transparency gap. Security headers such as Content-Security-Policy and Strict-Transport-Security are not explicitly observed, which could enhance protection against common web attacks. The use of third-party analytics (Mixpanel, Google Analytics) is managed with user consent, reflecting good privacy practices. Overall, Springest's security culture appears proactive but could benefit from formal documentation and additional technical controls to mitigate emerging threats and regulatory expectations.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and controls.
  2. Provide clear incident response contact information (e.g., security@ or abuse@ email).
  3. Implement and enforce HTTP security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security.
  4. Regularly audit and update third-party scripts and libraries to avoid vulnerabilities.
  5. Enhance transparency around data retention and user privacy beyond cookie consent.

Technical notes

Notes

The website is built on a custom stack utilizing jQuery 2.2.4 and Mixpanel for analytics, with assets served from multiple static subdomains for performance optimization. The site is mobile-responsive with good accessibility and SEO practices, including meta tags and structured data (JSON-LD). No CMS or hosting provider details are explicitly detected. Performance is fast with efficient asset delivery. The technical implementation is modern but could be improved by adopting newer JavaScript frameworks and enhancing security headers. Overall, the infrastructure supports a scalable and user-friendly platform with minimal technical debt.
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.
