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

2 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 X-Frame-Options header

      Prevents clickjacking attacks

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

  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

Slot Boss operates in the online gambling sector, specifically targeting UK slot and live casino players. The business model relies on offering a variety of casino games, jackpots, and promotional deposit bonuses to attract and retain customers. The platform's market positioning appears to be focused on the UK market with a medium-sized operation. The lack of explicit business registration or contact information on the site limits the ability to fully assess corporate structure or partnerships. The use of modern frontend frameworks and CDN-hosted assets indicates investment in digital experience. However, the absence of privacy and cookie policies, as well as WHOIS transparency, may impact customer trust and regulatory compliance. The company should consider enhancing transparency and compliance documentation to strengthen its market position and customer confidence.

Security posture

The website enforces HTTPS with a good SSL configuration, which is a fundamental security requirement. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces the overall security posture. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site lacks visible incident response contacts or security policies, which are important for handling security incidents and vulnerabilities. There is no evidence of a security.txt file or vulnerability disclosure program. Privacy compliance is weak due to missing privacy and cookie policies and lack of consent mechanisms. To improve security maturity, the platform should implement comprehensive security headers, publish clear privacy and cookie policies, provide incident response contacts, and establish a vulnerability disclosure process.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish comprehensive privacy and cookie policies with clear GDPR compliance and consent mechanisms.
  3. Provide clear contact information including security incident response and data protection officer contacts.
  4. Establish a security.txt file and vulnerability disclosure program to encourage responsible reporting.
  5. Enhance accessibility features and conduct regular security audits to identify and remediate vulnerabilities.

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.
