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

Lambda is a specialized deep tech venture studio operating under the Ergodic Group umbrella, focusing on advanced engineering solutions across multiple high-tech domains such as cryptography, machine learning, and distributed systems. Founded in 2014 in Argentina, it has expanded internationally with offices in South America and Europe. The company emphasizes engineering excellence, open source contributions, and a partnership-based engagement model rather than traditional staff augmentation. Technically, the website is well-constructed with modern technologies including Rust-based projects and privacy-first analytics, hosted on Cloudflare with a domain registered via Amazon Registrar. Security posture is strong with HTTPS and domain protection flags, though improvements can be made by enabling DNSSEC and publishing formal security and privacy policies. The site is professional, trustworthy, and safe for general audiences, but lacks some compliance documentation such as privacy and cookie policies. Overall, Lambda presents as a credible and technically mature organization with a clear focus on innovation and engineering quality.

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

9 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

Lambda occupies a niche market as a deep tech venture studio, leveraging expertise in cutting-edge technologies to serve clients requiring advanced system development. Its business model is partnership-driven, focusing on shared goals and independent work rather than hourly billing, which differentiates it from typical software consultancies. The company’s open source projects and sponsorships enhance its reputation and community engagement. Target customers are likely technology companies and research organizations seeking specialized engineering talent. The presence of multiple international offices indicates moderate size and growth. The parent company, Ergodic Group, provides additional business stability and resources. The company’s transparent and demanding hiring process suggests a strong internal culture focused on quality and fit. Overall, Lambda’s competitive advantage lies in its deep technical expertise, open source leadership, and commitment to engineering excellence.

Security posture

Lambda’s website and domain infrastructure demonstrate a solid security foundation with HTTPS enforced and domain status flags preventing unauthorized changes. The absence of DNSSEC is a minor gap that could be addressed to enhance DNS security. No forms or inputs on the homepage reduce attack surface, and no sensitive data is exposed. The use of privacy-first analytics tools indicates a privacy-conscious approach. However, the lack of published privacy, cookie, security, or incident response policies represents a compliance gap, especially relevant under GDPR and other regulations. No vulnerability disclosure or security.txt files were found, limiting transparency for security researchers. Overall, the security posture is good but could be improved by formalizing policies and enabling additional DNS security features.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies to improve GDPR and privacy compliance.
  3. Create and publish a security policy and incident response plan to enhance transparency and readiness.
  4. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Implement explicit security headers such as Content-Security-Policy and X-Content-Type-Options to harden the website.

Technical notes

Notes

The website uses modern web standards with valid HTML and CSS, and imports a custom font from Google Fonts. The tech stack includes Rust-based projects and cryptographic tools, reflecting the company’s deep technical focus. Hosting and DNS are managed via Cloudflare, providing performance and security benefits. Analytics are implemented with privacy-first tools, minimizing user tracking. The site loads quickly and is mobile optimized with good navigation clarity. No CMS or large frameworks were detected, indicating a lightweight and custom-built site. There are no visible technical debts or deprecated technologies. Opportunities exist to improve accessibility features and SEO further by adding ARIA roles and richer metadata. Overall, the technical implementation is robust and aligned with the company’s engineering ethos.
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.
