Bitcoin L2 Labs is a small technology company specializing in core product development for Stacks, a leading Bitcoin Layer 2 solution. The company focuses on building scalable, permissionless, and programmable technology to leverage Bitcoin as the foundation for the digital economy. Their market position is that of a core contributor to the Stacks ecosystem, targeting developers and blockchain enthusiasts. The website reflects a professional and consistent brand image with clear messaging about their mission and services. Technically, the website is built on the Tilda CMS platform, utilizing modern web fonts and JavaScript libraries served from Tilda's CDN. The site is mobile optimized and performs moderately well, with basic SEO and accessibility features. Hosting is managed via NameCheap's DNS servers, and HTTPS is properly configured. From a security perspective, the site uses HTTPS and has domain transfer protection enabled, but lacks DNSSEC and explicit security headers, which are recommended for enhanced security. No privacy, cookie, or incident response policies are present, indicating compliance gaps. Analytics are handled via Plausible Analytics, which is privacy-focused and minimally invasive. Overall, the website is safe, professional, and relevant to its audience, but improvements in privacy compliance, security headers, and contact transparency are advised to strengthen trust and regulatory adherence.

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

7 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 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

    • 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

Bitcoin L2 Labs operates in the blockchain technology sector, specifically focusing on the Stacks protocol which enables smart contracts and decentralized applications on Bitcoin. Their business model centers on core development and research, positioning themselves as essential builders within the Stacks ecosystem. The company targets developers, blockchain projects, and the broader Bitcoin community. The website indicates a growth-oriented approach with emphasis on decentralization, developer experience, and ecosystem expansion. Partnerships with Stacks and GitHub repositories suggest active engagement in open-source development. The absence of direct revenue model details suggests funding may come from grants, partnerships, or token-related incentives. The company is relatively new, founded in 2023, and maintains a focused and consistent brand presence.

Security posture

The security posture of Bitcoin L2 Labs' website is moderate. HTTPS is enforced, and the domain has clientTransferProhibited status, which prevents unauthorized domain transfers. However, DNSSEC is not enabled, which could expose the domain to DNS spoofing attacks. The website lacks explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which are important for mitigating common web vulnerabilities. No sensitive data or credentials are exposed in the HTML content. There is no visible incident response or vulnerability disclosure policy, which limits transparency in handling security issues. Analytics usage is privacy-conscious, using Plausible Analytics. Overall, while basic security measures are in place, there is room for improvement in DNS security, HTTP headers, and compliance documentation.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve domain security.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  3. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements to enhance legal compliance and user trust.
  4. Add explicit contact information and incident response details, including security contact emails, to improve transparency and readiness.
  5. Regularly audit and update third-party scripts and dependencies to avoid vulnerabilities and maintain a secure technology stack.

Technical notes

Notes

The website is built using the Tilda CMS platform, leveraging modern web fonts (Manrope and Source Code Pro) and JavaScript libraries hosted on Tilda's CDN. The site uses Plausible Analytics for lightweight, privacy-focused user tracking. The hosting and DNS are managed via NameCheap, with domain registration consistent with the business timeline. The site is mobile responsive and has a professional design with good navigation clarity. Performance is moderate, with no major issues detected. However, the absence of DNSSEC and security headers indicates technical debt in security hardening. The lack of structured data such as JSON-LD limits SEO potential. Overall, the technical infrastructure is adequate for a small technology company but could benefit from enhanced security and SEO optimizations.
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.
