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

Starknet is a blockchain technology platform focused on scaling Bitcoin and Ethereum through advanced zero-knowledge proof technology (STARKs). It provides a Layer 2 scaling solution that enhances computational integrity and scalability while maintaining security and decentralization. The platform targets developers, DeFi users, and the broader crypto community, offering extensive developer resources, tools, and ecosystem support including wallets, bridges, and grants. The website is professionally designed, well-structured, and optimized for user experience across devices. Technically, it leverages WordPress CMS with modern libraries and frameworks, integrating Google Tag Manager and reCAPTCHA for analytics and security. Security posture is strong with HTTPS and secure form handling, though some security headers and explicit policies could be improved. WHOIS data is privacy protected, which is common in this sector, but the domain is actively maintained and consistent with the business identity. Overall, Starknet presents a credible, trustworthy, and technically mature web presence aligned with its innovative blockchain services.

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 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
  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

Starknet occupies a leading position in the blockchain Layer 2 scaling market, uniquely bridging Bitcoin and Ethereum ecosystems. Its competitive advantage lies in its use of STARK technology for computational integrity and scalability, attracting a rapidly growing developer community. The business model focuses on providing infrastructure, developer tools, and ecosystem grants to foster innovation and adoption. Revenue streams likely include ecosystem partnerships and developer engagement. The target customers are blockchain developers, DeFi projects, and crypto users seeking scalable solutions. The company maintains active partnerships with ecosystem projects and community platforms, enhancing its market reach and credibility. Strategic observations highlight strong community engagement, continuous content updates, and a focus on decentralization and security.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of Google reCAPTCHA v3 to protect forms, and no visible exposure of sensitive data. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents an area for improvement. There is no publicly available security policy or incident response information, which could enhance transparency and preparedness. No vulnerabilities or outdated libraries were detected in the front-end code. Compliance with GDPR is implied through the privacy policy, but cookie consent mechanisms are not evident. Overall, the security maturity is good but could benefit from enhanced header policies and formal vulnerability disclosure channels.

Recommendations

  1. Implement comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response page to improve transparency and readiness.
  3. Add a cookie consent banner or mechanism to comply fully with privacy regulations and improve user trust.
  4. Consider establishing a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  5. Maintain regular WHOIS data updates and consider publishing verified business contact information to enhance trust.

Technical notes

Notes

The website is built on WordPress CMS using the GeneratePress theme, incorporating modern JavaScript libraries such as jQuery, Lottie for animations, and Slick for carousels. It integrates Algolia for search functionality and Google Tag Manager for analytics and tracking. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, with deferred loading of some scripts to improve initial load times. The technical stack is modern and well-maintained, though opportunities exist to optimize security headers and enhance privacy compliance. No technical debt or deprecated technologies were identified, indicating a well-managed infrastructure.
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.
