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

5 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 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
    • 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

Redis operates in the technology sector, focusing on database and real-time data solutions. Its business model includes offering cloud-managed services, self-managed software, and open-source products, catering to a broad developer audience and enterprise clients. The company benefits from a strong brand presence, extensive integrations with major cloud providers (AWS, Azure, Google Cloud), and a growing ecosystem around AI and semantic search technologies. Redis's market position is robust, supported by a decade-plus domain age and consistent branding. The partnership ecosystem includes official support and educational platforms, enhancing customer engagement and retention. Revenue streams likely derive from cloud subscriptions, enterprise software licenses, and professional services. Strategic observations highlight Redis's focus on innovation in AI and caching technologies, positioning it well for future growth in data-driven applications.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and domain registration protections such as clientTransferProhibited and clientUpdateProhibited statuses. However, DNSSEC is not enabled, which is a recommended enhancement for DNS security. No explicit security policies, incident response contacts, or vulnerability disclosure mechanisms are published, which limits transparency and may impact trust for security-conscious users. The absence of a security.txt file or dedicated security contact channels suggests an opportunity to improve incident response readiness. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The use of modern frameworks and absence of outdated libraries indicate good maintenance practices. Overall, the security posture is strong but could benefit from improved policy disclosures and DNS security enhancements.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies including GDPR compliance details and consent mechanisms.
  3. Add explicit security policy and incident response information, including security contact emails and a security.txt file.
  4. Provide clear and accessible contact information for general and security inquiries to improve transparency.
  5. Regularly audit third-party scripts and tracking tools to ensure minimal privacy impact and compliance.

Technical notes

Notes

The website is built using modern web technologies including Next.js and React, ensuring fast performance and excellent mobile responsiveness. Hosting is provided by Amazon AWS, inferred from DNS nameservers. The site uses advanced analytics tools such as Segment, Hockeystack, and Google Tag Manager for user behavior tracking and marketing insights. The design is professional and consistent, with good accessibility features and SEO optimization. No CMS was detected, indicating a custom or proprietary content management approach. The site employs Rive animations and lazy loading for images, contributing to a smooth user experience. Technical risks are minimal, but the lack of DNSSEC and explicit security disclosures represent areas for improvement. Overall, the technical infrastructure supports a high-quality, scalable digital presence aligned with business goals.
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.
