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"

  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 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

Notion holds a strong market position as a versatile AI workspace solution, integrating multiple productivity tools including AI chatbots, meeting notes, and project management. Its business model focuses on SaaS subscriptions with a broad target audience spanning startups to large enterprises. The company benefits from a rich ecosystem of partners and integrations, enhancing its competitive advantage. Customer testimonials and social proof from industry leaders reinforce its credibility. The absence of direct contact emails or phone numbers suggests a preference for digital engagement channels such as contact forms and demos. The platform's internationalization efforts indicate a global market reach.

Security posture

The website exhibits a mature security posture with enforced HTTPS, strict security headers, and privacy policies aligned with GDPR compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of publicly available incident response contacts and vulnerability disclosure policies represents a gap in transparency and readiness communication. The site uses secure forms and modern authentication mechanisms, but could improve by publishing explicit security certifications and incident response procedures. Overall, the security maturity is high but with room for enhanced transparency and user assurance.

Recommendations

  1. Publish a dedicated vulnerability disclosure policy and security.txt file to facilitate responsible reporting.
  2. Provide direct security contact emails (e.g., security@notion.com) to improve incident response communication.
  3. Disclose security certifications (e.g., ISO 27001) to strengthen trust with enterprise customers.
  4. Enhance transparency on data retention and processing policies to align with evolving privacy regulations.
  5. Regularly audit and minimize third-party scripts to reduce potential attack surface.

The site is mobile-optimized with responsive design and accessibility considerations. SEO is well addressed through meta tags and Open Graph data.

Overall, the technical implementation is modern, performant, and scalable, supporting a high-quality user experience.
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.
