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

Rubylight Technology Ltd is a small, Latvia-based technology investment company founded in 2010. The company specializes in providing venture capital funding combined with technical and operational support to fast-growing internet and mobile startups globally. Their portfolio includes 24 investments and 7 successful exits, demonstrating a solid market position in the technology investment sector. The website presents a professional image with detailed information about their team, investment philosophy, and portfolio companies. Technically, the website uses standard web technologies including HTML5, CSS3, JavaScript, and jQuery, hosted on AWS infrastructure. Google Analytics is used for visitor tracking, but no cookie consent mechanism or privacy policy is visible, indicating gaps in privacy compliance. Security posture is moderate with HTTPS enforced via client-side redirect, but the use of an outdated jQuery version and absence of security headers are notable vulnerabilities. Overall, the website is functional and professional but would benefit from enhanced security and privacy practices.

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

8 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

Rubylight operates as a venture capital firm with a unique value proposition combining financial investment with hands-on technical and operational support. Their focus on consumer internet and mobile startups in areas like social media, communication, and content sharing aligns with their expertise and portfolio. The company emphasizes fast decision-making and international investments, targeting startups with proven user growth. Their publicly disclosed portfolio includes notable companies such as Sweatcoin, Jodel, and Bolt, indicating strong market connections and a credible investment track record. The absence of direct contact emails or phone numbers suggests a controlled communication channel via a contact form, possibly to filter inquiries. The company leverages LinkedIn for professional presence and networking. Overall, Rubylight demonstrates a focused and experienced approach to technology investments with a clear niche and growth orientation.

Security posture

The website enforces HTTPS, which is a fundamental security requirement. However, the redirect from HTTP to HTTPS is implemented via client-side JavaScript rather than server-side, which is less secure and may expose users briefly to unsecured connections. The site lacks important security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which are recommended to mitigate common web attacks. The use of an outdated jQuery version (1.7.2) introduces potential vulnerabilities that could be exploited. No privacy policy, cookie consent, or incident response information is provided, indicating gaps in compliance and security transparency. There is no visible vulnerability disclosure or security contact information, which reduces trust and incident handling readiness. Overall, the security posture is moderate but requires improvements to meet best practices and regulatory compliance.

Recommendations

  1. Implement server-side HTTPS redirection to ensure secure connections from the start.
  2. Update all JavaScript libraries, especially jQuery, to current secure versions to mitigate known vulnerabilities.
  3. Add comprehensive privacy and cookie policies with visible consent mechanisms to comply with GDPR and other regulations.
  4. Deploy security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  5. Publish a vulnerability disclosure policy or security.txt file and provide clear security contact information to improve incident response and transparency.

Technical notes

Notes

The website is built with standard web technologies including HTML5, CSS3, and JavaScript, with jQuery 1.7.2 loaded asynchronously from Google's CDN. Google Analytics is integrated via gtag.js for visitor tracking. The site is hosted on infrastructure indicated by AWS nameservers, suggesting reliable hosting. The website design is professional and consistent, with responsive elements but limited mobile optimization (viewport fixed at width=900). Performance is moderate with no major blocking scripts detected. Accessibility features are basic, with no ARIA roles or landmarks identified. SEO optimization is basic with meta description and keywords present but no Open Graph or structured data markup found. The site uses an iframe for the contact form, which may limit direct data control. Overall, the technical implementation is solid but could be modernized with improved mobile responsiveness, updated libraries, and enhanced accessibility and SEO features.
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.
