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

Notion Labs, Inc. operates a leading AI-powered workspace platform designed to unify everyday work into a single flexible environment. Their services include AI-enhanced note-taking, project management, enterprise search, and collaboration tools targeting teams ranging from startups to large enterprises. The website demonstrates a mature digital presence with modern technologies such as React and Next.js, optimized for performance and mobile responsiveness. Security posture is strong with HTTPS enforcement and comprehensive security headers, though the absence of explicit incident response contacts and vulnerability disclosure policies suggests room for improvement. The missing WHOIS data is a notable anomaly but does not detract from the overall legitimacy indicated by extensive social proof and professional branding. Strategic recommendations include enhancing transparency around security incident handling and publishing vulnerability disclosure information.

NIS2 Art. 21(2)

  1. (a) Risk analysis and security policies: Not visible from outside

  3. (c) Business continuity, backups and crisis management: Not visible from outside
  4. (d) Supply chain security: Not visible from outside

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

    • 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

  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 with a SaaS subscription model. Their customer base includes major technology companies and Fortune 100 enterprises, supported by a robust ecosystem of integrations with popular platforms like Slack, Google Drive, and GitHub. The company leverages AI to differentiate its offerings, providing automated meeting notes, enterprise search, and AI writing capabilities. Their marketing emphasizes productivity gains and tool consolidation, appealing to a broad range of business sectors. The website content and testimonials reflect a well-established brand with significant user adoption and community engagement.

Security posture

The website exhibits a high level of security maturity with enforced HTTPS, multiple security headers, and secure form implementations. No vulnerabilities or exposed sensitive data were detected in the HTML content. However, the lack of a public vulnerability disclosure policy and incident response contact details limits transparency and may hinder rapid security issue reporting. Compliance with GDPR is indicated by the presence of privacy and cookie policies with consent mechanisms. Overall, the security posture is strong but could be enhanced by formalizing incident response and disclosure processes.

Recommendations

  1. Publish a dedicated vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  2. Provide clear incident response contact information, such as a security@ or abuse@ email address.
  3. Consider obtaining and displaying recognized security certifications to boost trust.
  4. Enhance transparency around data retention and privacy compliance details.
  5. Maintain regular WHOIS data accuracy and transparency to improve domain trustworthiness.

Technical notes

Notes

The website is built on a modern tech stack including React and Next.js, ensuring fast loading times and excellent mobile optimization. The use of structured metadata and Open Graph tags supports SEO and social media sharing. The site employs best practices in accessibility and performance optimization. No deprecated or vulnerable libraries were detected. The infrastructure supports a seamless user experience with rich interactive content and multimedia elements. Opportunities exist to improve technical documentation around security and compliance for end users.
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.
