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

Hashnode operates in the technology sector as a platform service targeting developers and teams. Its competitive advantage lies in its AI-powered blogging and documentation tools, seamless GitHub integration, and a large active user base. The business model likely includes freemium or subscription services for enhanced features. The company shows growth indicators through its large user trust and modern platform capabilities. Partnerships and integrations with major platforms like GitHub and Cloudflare enhance its ecosystem. Strategic observations suggest focusing on compliance and security transparency to strengthen market trust further.

Security posture

The security maturity of Hashnode is moderate to good. HTTPS is enforced, and domain registration includes multiple client protection statuses, indicating domain security awareness. However, the absence of DNSSEC and security headers like Content-Security-Policy or X-Frame-Options represents gaps. No explicit security policies or incident response contacts are published, which could hinder rapid response to incidents. Privacy compliance is partial due to missing explicit policies. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Enhancing security transparency and technical controls would improve the overall posture.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve DNS security.
  2. Implement and publish comprehensive privacy and cookie policies with user consent mechanisms to ensure GDPR compliance.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the website against common attacks.
  4. Publish a security policy and incident response contact information to improve transparency and readiness.
  5. Regularly audit third-party scripts and libraries to avoid vulnerabilities and maintain secure integrations.

Technical notes

Notes

The website uses a modern technology stack including React and Next.js, with Cloudflare DNS and CDN services. It integrates Google Fonts and analytics tools like Google Analytics and Microsoft Clarity, alongside Twitter Ads for marketing. The site is mobile-optimized, fast-loading, and well-structured with proper meta tags for SEO. No CMS detected, indicating a custom-built platform. Technical risks include lack of DNSSEC and missing security headers. The infrastructure is robust but could benefit from enhanced security configurations and formalized compliance documentation.
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.
