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

6 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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. 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

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

Supermemory.ai operates in the technology sector, targeting developers and AI users with a SaaS API platform that enhances AI memory capabilities. The business model revolves around providing API services that integrate with various applications to personalize AI experiences. Market positioning is that of an innovative startup with a growing community, leveraging open-source presence on GitHub and social media to build credibility. Revenue streams likely include subscription or usage-based API access. The company maintains a lean profile with no public physical addresses or phone numbers, relying on digital channels for contact and support. Strategic partnerships or subsidiaries are not evident from the data. Growth indicators include recent domain registration and active content updates. The company emphasizes developer empowerment and seamless integration as competitive advantages.

Security posture

The security maturity of supermemory.ai is moderate. The website enforces HTTPS and uses Cloudflare DNS with clientTransferProhibited status to prevent unauthorized domain transfers. However, DNSSEC is not enabled, and no security headers such as Content Security Policy or HSTS were detected, which are recommended best practices. There is no published security policy or incident response plan visible on the site, nor a vulnerability disclosure or security.txt file, indicating gaps in transparency and readiness. The use of PostHog analytics introduces moderate user tracking, but no cookie consent mechanism is present, which may raise privacy compliance concerns under GDPR. No vulnerabilities or exposed sensitive data were found in the content. Overall, the security posture is adequate for a startup but should be enhanced to meet higher compliance and trust standards.

Recommendations

  1. Enable DNSSEC to improve domain name system security and prevent DNS spoofing.
  2. Implement standard security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to mitigate common web attacks.
  3. Add a cookie consent banner or mechanism to comply with privacy regulations and inform users about tracking.
  4. Publish a clear security policy and incident response plan to enhance transparency and preparedness.
  5. Consider establishing a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.

Technical notes

Notes

The website is built on the Astro framework, a modern static site generator optimized for performance and developer experience. It uses Three.js for graphical elements and UnicornStudio for interactive scenes, indicating advanced front-end capabilities. Hosting and DNS are managed via Cloudflare, providing robust infrastructure and CDN benefits. Analytics are handled by PostHog, a privacy-focused analytics platform. The site demonstrates fast loading times, excellent mobile responsiveness, and good SEO practices with comprehensive meta tags including Open Graph and Twitter cards. No CMS was detected, suggesting a custom or static site approach. Technical risks include lack of DNSSEC and missing security headers, which could expose the site to certain attack vectors. Overall, the technical implementation is modern and well-executed with room for security hardening.
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.
