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

Notion Labs, Inc. operates a leading AI-powered workspace platform designed to unify everyday work for teams and businesses of all sizes. Their platform integrates AI tools such as search, writing, and note-taking within a flexible all-in-one workspace, serving a broad audience including startups, SMBs, enterprises, and educational institutions. The company enjoys a strong market position with over 100 million users worldwide and adoption by major corporations such as OpenAI and Toyota. Their business model is primarily SaaS-based, offering free tiers and enterprise solutions. Technically, Notion's website is built on modern web technologies including React and Next.js, delivering a fast, mobile-optimized, and accessible user experience. The site features rich multimedia content, comprehensive product information, and multi-language support, reflecting a mature digital infrastructure. Hosting and CMS details are not explicitly disclosed but the performance and design quality indicate a robust setup. From a security perspective, the website enforces HTTPS, employs multiple security headers, and follows best practices for secure forms and data handling. However, explicit incident response and vulnerability disclosure policies are not publicly available, and no direct security contact emails were found. The absence of WHOIS data is notable and may indicate privacy protection or registry restrictions, though the website's professional presence mitigates immediate concerns. Overall, Notion presents a high-quality, trustworthy digital presence with strong business credibility and security posture. Strategic improvements include publishing detailed security policies and enhancing transparency around incident response. The risk level is low, with no critical vulnerabilities or compliance gaps detected in the analyzed content.

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 is positioned as a dominant player in the AI workspace and productivity SaaS market, leveraging AI to differentiate its offerings. Its competitive advantages include a unified platform approach, extensive integrations, and a large, diverse user base. Revenue streams likely include subscription fees from individual, team, and enterprise plans. Target customers span multiple sectors and team sizes, supported by tailored templates and integrations. The company maintains a strong partnership ecosystem and brand presence, with endorsements from high-profile clients. Growth indicators include new product launches like AI Meeting Notes and Enterprise Search, and continuous platform enhancements.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and secure form implementations. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of publicly available incident response and vulnerability disclosure information suggests room for improvement in transparency and readiness communication. GDPR compliance is indicated through privacy and cookie policies with consent mechanisms. The absence of direct security contact channels may hinder rapid incident reporting. Overall, the security culture appears strong but could benefit from enhanced public-facing security governance documentation.

Recommendations

  1. Publish a dedicated vulnerability disclosure and incident response policy page to improve transparency and trust.
  2. Provide direct security contact emails such as security@notion.com or abuse@notion.com for reporting issues.
  3. Consider obtaining and displaying recognized security certifications (e.g., ISO 27001) to reinforce security posture.
  4. Enhance privacy compliance disclosures with detailed data retention and processing information.
  5. Maintain regular WHOIS data availability or provide justification for privacy protection to avoid trust concerns.

Technical notes

Notes

Notion's website is built using modern JavaScript frameworks React and Next.js, enabling server-side rendering and optimized performance. The site is well-structured with semantic HTML, responsive design, and accessibility considerations. Multimedia content such as videos and SVG icons are efficiently integrated. SEO is supported by comprehensive meta tags and Open Graph data. No CMS is explicitly identified, suggesting a custom or headless CMS solution. Hosting details are not disclosed but performance and uptime indicators suggest a reliable cloud hosting provider. Technical risks are minimal, with no deprecated or vulnerable libraries detected.
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.
