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

Instructure is a leading educational technology company specializing in learning management systems (LMS) and edtech solutions for K–12, higher education, and business sectors. Their flagship product, Canvas LMS, is widely adopted and supported by a robust ecosystem of partners and community engagement. The company positions itself as a comprehensive provider of digital learning tools that empower educators and learners alike. Technically, the website is built on Drupal 10 CMS and leverages a modern technology stack including Google Tag Manager, Marketo, Microsoft Clarity, and various front-end libraries for performance and user experience. The site is mobile-optimized, accessible, and SEO-friendly, reflecting a mature digital infrastructure. From a security perspective, the site enforces HTTPS, employs multiple security headers, and integrates cookie consent mechanisms indicating GDPR compliance. Certifications such as SOC 2 and ISO 27001 further demonstrate a commitment to security standards. However, the absence of a publicly accessible security policy and incident response contact details suggests room for improvement in transparency and readiness. Overall, Instructure's website reflects a professional, trustworthy, and well-maintained digital presence aligned with its enterprise market position. The missing WHOIS data is a notable anomaly but does not significantly detract from the overall credibility given the strong branding and operational indicators.

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 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

  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 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

      SSL Certificate Expires Soon

      SSL certificate expires in 24 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

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

Instructure operates in the education technology sector with a focus on SaaS LMS solutions. Their market positioning is strong, supported by a broad customer base across K–12, higher education, and corporate training. The business model centers on subscription-based software services with additional revenue from professional development and assessment tools. Strategic partnerships and a vibrant community ecosystem enhance their competitive advantage. The company demonstrates global reach with multilingual website support and localized content. Growth indicators include continuous product innovation and extensive marketing and analytics investments.

Security posture

The website exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and adherence to privacy regulations including GDPR. The presence of SOC 2 and ISO 27001 certifications indicates robust internal controls and risk management. No immediate vulnerabilities or exposed sensitive data were detected. However, the lack of a dedicated security policy page and incident response contact reduces transparency and may impact stakeholder confidence. The absence of a vulnerability disclosure program or security.txt file limits external security collaboration opportunities. Overall, the security posture is strong but could benefit from enhanced communication and formalized disclosure mechanisms.

Recommendations

  1. Publish a detailed security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information to facilitate reporting and communication.
  3. Implement and publicize a vulnerability disclosure program including a security.txt file.
  4. Enhance transparency around data protection officer contact details and data handling practices.
  5. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a modern Drupal 10 CMS platform with a well-integrated tech stack including Google Fonts, Google Tag Manager, Marketo, and Microsoft Clarity for analytics and marketing automation. Front-end technologies such as Slick Carousel, Foundation CSS, and AOS provide a responsive and engaging user experience. Performance is moderate with room for optimization in script loading and asset management. Accessibility features are implemented to a good standard, supporting diverse user needs. SEO practices are evident through meta tags, Open Graph data, and structured JSON-LD markup. Hosting details are not explicitly identified but the infrastructure supports enterprise-grade availability and security.
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.
