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"

    • 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

  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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Upstash operates a SaaS business model focused on serverless data infrastructure, catering primarily to developers and enterprises requiring scalable, globally distributed databases and messaging services. Its competitive advantage lies in offering HTTP/REST APIs alongside traditional Redis protocol support, enabling seamless integration with serverless and edge computing platforms. The company maintains a consistent brand and content strategy, highlighting uptime guarantees, global low latency, and automatic scaling. Partnerships and integrations with platforms like Vercel and Cloudflare are implied through technical optimizations. The absence of direct contact emails suggests a preference for managed support channels, possibly to streamline customer interactions. Growth indicators include active community channels and frequent product updates via blog and social media.

Security posture

The website exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and no visible exposure of sensitive data or vulnerable libraries. However, the lack of a published vulnerability disclosure policy or security.txt file and absence of explicit incident response contact channels represent gaps in transparency and readiness. Cookie consent mechanisms are not evident, which may impact GDPR compliance. The presence of updated privacy and data protection agreements indicates awareness of regulatory requirements. Overall, the security maturity is strong but could benefit from enhanced transparency and user privacy controls.

Recommendations

  1. Implement a clear cookie consent banner to comply with privacy regulations and enhance user trust.
  2. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting.
  3. Provide explicit incident response contact information, such as security@ or abuse@ email addresses.
  4. Add verified company contact emails and phone numbers to improve business credibility and user support.
  5. Consider obtaining and displaying relevant security certifications to strengthen trust signals.

Technical notes

Notes

The website is built using modern web technologies including Next.js and React, indicating a contemporary and scalable architecture. It is likely hosted on a platform such as Vercel, optimized for performance and global delivery. The site demonstrates fast loading times, excellent mobile responsiveness, and good SEO practices with proper meta tags and Open Graph data. Accessibility features are present but could be further enhanced. No technical debt or legacy technology indicators were found. The use of third-party services like Google Tag Manager and Intercom supports analytics and customer engagement but should be balanced with privacy compliance measures.
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.
