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

Notion Labs Inc. operates www.notion.com, a leading AI-powered workspace platform designed to enhance team productivity by integrating AI agents, enterprise search, and collaboration tools. The company targets teams and businesses seeking to streamline workflows and automate busywork through a SaaS subscription model with free and enterprise tiers. The website showcases a modern, multimedia-rich experience with strong branding and customer trust signals from major partners like OpenAI and Figma. Technically, the site leverages modern web technologies including React and Next.js, delivering fast performance and excellent mobile optimization. Security is robust with HTTPS enforcement and comprehensive security headers, although explicit incident response and vulnerability disclosure information are not publicly available. Privacy and cookie policies are present and indicate GDPR compliance. Overall, the security posture is strong with no visible vulnerabilities or exposed sensitive data. The absence of WHOIS data is likely due to privacy protection, which is justified for a company of this size and nature. The website is professional, trustworthy, and safe for general audiences, with no adult or questionable content detected.

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

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 platform, serving a broad range of industries with a focus on technology and enterprise customers. Its business model centers on SaaS subscriptions, supported by a rich ecosystem of integrations and AI-driven features. The company benefits from strategic partnerships with industry leaders, enhancing its credibility and reach. Growth indicators include extensive user base claims and high-profile customer testimonials. The website content and structure reflect a mature digital presence aligned with enterprise-grade service offerings.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, multiple security headers, and secure form implementations. However, it lacks publicly disclosed incident response contacts and vulnerability disclosure policies, which are recommended for transparency and rapid mitigation of security issues. Privacy compliance is well addressed with clear policies and consent mechanisms. No critical vulnerabilities or security misconfigurations were detected in the analyzed content.

Recommendations

  1. Publish a dedicated vulnerability disclosure policy and security.txt file to facilitate responsible reporting.
  2. Provide direct security contact information such as security@ or abuse@ email addresses.
  3. Consider obtaining and displaying recognized security certifications (e.g., ISO 27001) to enhance trust.
  4. Enhance transparency around incident response procedures and data retention policies.
  5. Maintain continuous monitoring of third-party scripts and dependencies to prevent vulnerabilities.

Technical notes

Notes

The website is built on a modern React and Next.js stack, ensuring server-side rendering and optimized performance. Multimedia content is efficiently delivered with preloading and responsive images. The site is mobile-optimized and accessible, with semantic HTML and ARIA roles. SEO is supported by comprehensive meta tags and Open Graph data. No CMS was explicitly detected, suggesting a custom or headless CMS solution. Hosting details are not explicit but likely use a scalable cloud provider. Overall, the technical implementation supports a high-quality user experience 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.
