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
    • 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 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 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

Blockster operates as a media publishing platform within the Web3 and blockchain sector, generating revenue likely through advertising and membership publishing. Its competitive advantage lies in its focused content on Web3 culture and lifestyle, appealing to a growing crypto-savvy audience. The company maintains an active presence on social media platforms like Twitter and YouTube, enhancing its community engagement. The business model emphasizes content creation and curation, with partnerships and collaborations implied but not explicitly detailed. Growth indicators include regular content updates and a diverse range of topics covering emerging blockchain trends. The lack of explicit contact details and privacy compliance mechanisms suggests areas for operational maturity improvement.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and domain registration protections in place. However, it lacks critical security headers such as Content-Security-Policy and X-Frame-Options, which are important for mitigating common web vulnerabilities. The absence of DNSSEC reduces DNS security robustness. No vulnerability disclosure or incident response policies are published, which could hinder timely security issue management. Data protection practices are basic, with no visible GDPR cookie consent or privacy controls. The use of Google Analytics indicates user tracking without explicit privacy transparency. Overall, the security posture is adequate for a media platform but requires enhancements to align with best practices and regulatory compliance.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a cookie consent banner and privacy controls to improve GDPR compliance and user transparency.
  4. Publish a security policy and incident response contact information to build trust and facilitate vulnerability reporting.
  5. Provide explicit company contact emails and phone numbers to improve business credibility and user support.

Technical notes

Notes

The website is built on a modern tech stack featuring the Elixir Phoenix framework with LiveView for real-time interactivity, supported by ImageKit for optimized image delivery. Google Tag Manager and Google Analytics are integrated for marketing and analytics purposes. The site is mobile responsive with good SEO meta tags and Open Graph data for social sharing. Hosting details are not explicit but DNS is managed via Cloudflare. Performance is moderate with lazy loading of images and deferred JavaScript. Accessibility features are basic but present. The site lacks some security best practices such as security headers and DNSSEC. Overall, the technical infrastructure is solid but could benefit from enhanced security and privacy features.
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.
