ChainSecurity, operated by Decentralized Security AG, is a Swiss-based company specializing in smart contract audits and blockchain security consulting. Since 2017, it has established itself as a trusted partner for leading DeFi protocols, central banks, and international corporations. The company offers comprehensive smart contract auditing services, leveraging expertise in decentralized finance and blockchain technology to ensure security and reliability for its clients. The website reflects a professional and well-branded digital presence, emphasizing transparency through public audit reports and client testimonials. Technically, the website is built on the Webflow CMS platform, utilizing modern JavaScript libraries such as jQuery, GSAP, and Swiper.js for enhanced user experience and interactivity. The site is well-optimized for mobile devices, loads quickly, and includes accessibility features. Security measures include HTTPS enforcement and the use of Google reCAPTCHA to protect forms, although explicit security headers and cookie consent mechanisms are absent. From a security posture perspective, the site demonstrates good practices but could improve by adding security headers, publishing a vulnerability disclosure policy, and implementing cookie consent to enhance privacy compliance. The absence of WHOIS data for the domain introduces some uncertainty regarding domain registration legitimacy, although the business content and client references strongly support its authenticity. Overall, ChainSecurity presents a credible and professional front in the blockchain security space, with recommendations to strengthen technical security and privacy compliance to further solidify 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

4 findings rated critical or high. Fix these first.

  1. 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

  2. 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

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Domain Expires Soon

      Domain expires in 29 days

      What to do: Renew domain registration before expiration

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

ChainSecurity operates in the niche market of blockchain and DeFi security auditing, targeting high-value clients such as DeFi projects, research institutions, and central banks. Its competitive advantage lies in its specialized expertise, long-standing presence since 2017, and transparent publication of audit reports. The business model revolves around providing security audits and consulting services, generating revenue from institutional clients requiring smart contract validation. The company maintains a medium-sized operation based in Switzerland, a jurisdiction known for strong financial and data protection regulations. Partnerships with major DeFi protocols and endorsements from clients like MakerDAO and Curve enhance its market credibility. Growth indicators include a steady stream of audit reports and active blog content demonstrating thought leadership. Strategic observations suggest focusing on expanding incident response capabilities and formalizing security policies to meet evolving compliance requirements.

Security posture

The website's security maturity is moderate to good. HTTPS is properly implemented, and Google reCAPTCHA protects user input forms, reducing spam and automated abuse. However, the lack of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options represents a gap that could expose the site to certain web-based attacks. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a published vulnerability disclosure policy or security.txt file limits transparency and responsiveness to security incidents. GDPR compliance is indicated by the presence of a privacy policy, but cookie consent mechanisms are missing, which could be a compliance risk. Incident response contact information is not explicitly provided, which may delay handling of security issues. Overall, the security posture is adequate for a professional service provider but would benefit from enhancements in headers, policies, and incident readiness.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to harden web security.
  2. Add a cookie consent banner or mechanism to comply with GDPR and enhance user privacy transparency.
  3. Publish a formal vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Provide explicit incident response contact channels such as security@ or abuse@ email addresses.
  5. Regularly verify and update WHOIS domain registration information to ensure transparency and trustworthiness.

Technical notes

Notes

The website is built on a modern and scalable Webflow CMS platform, leveraging popular JavaScript libraries like jQuery, GSAP for animations, and Swiper.js for interactive sliders. The site is well-structured with semantic HTML and optimized for mobile responsiveness and accessibility. Performance is fast with efficient use of CDN-hosted assets. SEO is supported by proper meta tags and Open Graph data for social sharing. However, the site lacks some advanced security configurations such as security headers and cookie consent mechanisms. The absence of WHOIS data for the domain is a technical anomaly that should be investigated. Overall, the technical infrastructure supports a professional and user-friendly experience but can be improved in security and compliance aspects.
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.
