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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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. 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

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

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

Sparring positions itself as a niche legal service provider for technology-driven companies, leveraging expertise in emerging tech sectors like fintech, crypto, and AI. Their business model focuses on providing both template-based legal solutions and dedicated in-house legal support, targeting startups, scaleups, agencies, and investors. The company has a strong client base of over 100 innovative companies and maintains localized versions of its website for different markets (US, SK, CZ). Their partnership ecosystem includes clients like Deepnote and Vision Ventures, indicating a reputable market presence. The firm emphasizes transparency, technology know-how, and integration as part of their value proposition. Growth indicators include active content marketing via blogs, podcasts, and legal playbooks. The company operates as a small-sized entity with a focused sector approach.

Security posture

The website demonstrates a good security maturity level with HTTPS enforced, use of Google reCAPTCHA to protect forms, and a GDPR-compliant cookie consent mechanism. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options were not detected in the provided content, representing an area for improvement. No vulnerabilities or exposed sensitive data were found in the HTML content. The absence of a published security policy, incident response contacts, or vulnerability disclosure policy limits transparency and readiness for security incidents. Overall, the security posture is solid for a small professional services website but could be enhanced by adopting additional security best practices and publishing relevant policies.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages to improve compliance and user trust.
  2. Implement and verify security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Enable DNSSEC on the domain to enhance DNS security.
  4. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Provide direct contact information for security incidents, such as a dedicated security or abuse email address.

Technical notes

Notes

The website is built on WordPress using the Elementor page builder, supported by plugins for GDPR cookie consent and performance optimization (WP Rocket). It integrates Google Tag Manager, Google Analytics, Hotjar for user behavior analytics, and Google reCAPTCHA for bot protection. Hosting is provided by Websupport.sk, as indicated by the nameservers. The site is well-optimized for mobile devices and SEO, with proper meta tags, Open Graph, and JSON-LD structured data for enhanced search engine visibility. Performance appears fast with preloading of key images and asynchronous loading of scripts. The technical stack is modern and appropriate for a professional services website, with opportunities to improve security headers and DNS security.
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.
