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

NiceHash AG operates a leading cryptocurrency platform specializing in mining and hashrate marketplace services. The company provides a comprehensive ecosystem including mining software, a marketplace for buying and selling computing power, and Bitcoin payment solutions. Positioned as a global leader in the cryptocurrency mining industry, NiceHash targets miners, investors, and merchants seeking efficient and accessible blockchain mining and payment services. The website reflects a mature digital presence with professional branding, mobile app availability, and active community engagement across multiple social media platforms. Technically, the website leverages modern web technologies such as Vue.js and integrates Google Tag Manager and Analytics for performance and user behavior tracking. The site is mobile-optimized and demonstrates good SEO and accessibility practices. However, some security headers are not explicitly detected, and WHOIS data is missing, which slightly impacts transparency. The platform enforces HTTPS and provides privacy and cookie policies with consent mechanisms, indicating a commitment to user privacy and compliance. From a security perspective, NiceHash shows strengths in secure communications and privacy policy implementation but could improve by publishing explicit security headers and incident response contacts. The absence of WHOIS data is a concern but is mitigated by the company's strong market reputation and external presence. Overall, the platform presents a secure and professional environment suitable for its business model. The overall risk assessment is moderate with recommendations to enhance transparency and security posture. Strategic improvements in security headers, incident response visibility, and WHOIS data clarity would further strengthen trust and compliance.

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

3 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

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

NiceHash AG holds a prominent position in the cryptocurrency mining sector, operating a marketplace that connects miners and buyers of hashrate. Its business model revolves around facilitating mining operations without requiring hardware ownership, enabling users to buy or sell computing power. Revenue streams likely include transaction fees, mining software sales, and payment processing services. The company targets a global audience of cryptocurrency miners, investors, and merchants, supported by a robust ecosystem including mobile applications and developer tools. Partnerships and community engagement through social media and events like the NiceHashX Conference enhance its market presence. The company’s operations are consistent with a large technology enterprise based in Switzerland, founded in 2014, with a focus on accelerating Bitcoin adoption worldwide.

Security posture

The security posture of NiceHash is generally strong, with HTTPS enforced site-wide and comprehensive privacy and cookie policies in place. The presence of a bug bounty program indicates proactive vulnerability management. However, the lack of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No incident response contact information or security.txt file was found, which could hinder vulnerability reporting and incident handling. The missing WHOIS data reduces transparency but does not directly imply compromise. Overall, the platform demonstrates a mature security culture but would benefit from enhanced header configurations and clearer incident response channels to improve resilience and trust.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to strengthen browser security.
  2. Publish clear incident response contact information and consider adding a security.txt file to facilitate vulnerability disclosures.
  3. Clarify WHOIS domain registration details or ensure transparency regarding domain privacy to improve trustworthiness.
  4. Maintain and promote the bug bounty program to encourage responsible vulnerability reporting.
  5. Enhance monitoring and periodic security audits to ensure continued compliance with evolving security standards.

Technical notes

Notes

The website is built using modern JavaScript frameworks, specifically Vue.js, and integrates Google Tag Manager and Analytics for tracking. It supports mobile platforms with dedicated Android and iOS apps. The site uses manifest.json indicating progressive web app capabilities. Performance is moderate with good mobile optimization and accessibility features. No CMS was detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The technical implementation is solid but could improve with additional security headers and enhanced SEO metadata. Overall, the infrastructure supports a scalable and user-friendly experience aligned with the company’s business objectives.
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.
