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

SpryMedia Ltd operates in the technology sector, focusing on developer tools for web applications. Their business model combines open source software with commercial support and premium extensions, targeting web developers and enterprises needing advanced table functionalities. The company maintains a strong market position with a loyal user base and a rich ecosystem of extensions and integrations. Partnerships with ethical advertising networks and clear company registration details reinforce credibility. The website's content and navigation are tailored to technical audiences, emphasizing ease of use and extensibility. Growth indicators include active blog updates, community forums, and integration with modern JavaScript frameworks.

Security posture

The website employs HTTPS and Cloudflare DNS services, providing a solid baseline for secure communications. The domain is protected with clientTransferProhibited status, reducing risk of unauthorized transfers. No DNSSEC is enabled, which is a recommended improvement. The site does not expose sensitive data or use vulnerable libraries in the visible code. However, there is no explicit security policy, incident response contact, or vulnerability disclosure mechanism published, which are gaps in security transparency. Cookie consent mechanisms are absent, potentially impacting GDPR compliance. Security headers are not explicitly detected in the HTML content, suggesting room for enhancement. Overall, the security posture is good but could be strengthened with additional policies and technical controls.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and display a cookie consent banner to comply with GDPR and other privacy regulations.
  3. Publish a formal security policy and incident response contact information to improve transparency and trust.
  4. Add security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to enhance protection against common web attacks.
  5. Consider creating a vulnerability disclosure or security.txt file to facilitate responsible reporting of security issues.

Technical notes

Notes

The website uses a modern and well-maintained technology stack centered on Javascript and the DataTables library, with integrations for popular UI frameworks like Bootstrap, Bulma, React, and Vue. Hosting and DNS services are provided by Cloudflare, ensuring fast content delivery and DNS reliability. The site is mobile-optimized and accessible, with clean HTML and CSS. Performance is fast, supported by CDN usage for scripts and stylesheets. The site uses EthicalAds for advertising, which aligns with ethical marketing standards. There is no detected CMS, indicating a custom or static site architecture. Technical risks are minimal, but the absence of some security headers and privacy mechanisms suggests opportunities for modernization and compliance improvements.
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.
