0–100, higher is better. How it is calculated

STS Gaming Group is a leading gaming and betting company operating primarily in Central Europe with a strong presence in Poland and expanding across Europe. The company offers a comprehensive portfolio including sportsbook, virtual sports, casino, live casino, and esports betting. With over 1500 employees and multiple offices, STS has established itself as a major player in the gaming industry. The website is built on a modern Angular framework with responsive design and multimedia content, reflecting a mature digital infrastructure.

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

8 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.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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"

    • 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';…

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

STS Gaming Group holds a dominant market position in the Central and Eastern European gaming sector, leveraging a multi-channel business model that includes physical betting shops and online platforms. The company has demonstrated significant growth, expanding its revenue tenfold in recent years and acquiring complementary businesses such as Betsys. Strategic partnerships and sponsorships with sports teams and esports organizations enhance brand visibility and customer engagement. The target audience includes sports bettors and casino players across Europe, with a focus on innovation and customer experience. The company’s ecosystem includes multiple branded domains and a foundation supporting sports initiatives, indicating a diversified and socially responsible business approach.

Security posture

The website employs HTTPS and integrates standard analytics and marketing tools like Google Analytics, Google Tag Manager, and Hotjar, indicating a baseline security and monitoring setup. However, the lack of visible security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No vulnerability disclosure or incident response information is provided, which could hinder timely security issue reporting. Privacy compliance is weak due to missing privacy and cookie policies and absence of consent mechanisms. Overall, the security maturity is moderate, with strengths in encryption but gaps in policy transparency and header implementation.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance and user consent mechanisms.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  3. Publish a security.txt file and incident response contact information to facilitate vulnerability reporting.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve transparency.

Technical notes

Notes

The website is a single-page application built with Angular 13, utilizing Bootstrap 4 for responsive design and jQuery for legacy support. It integrates Swiper.js for interactive sliders and uses Google Analytics and Hotjar for user behavior tracking. The site loads asynchronously and defers scripts to optimize performance, achieving moderate loading speeds. The absence of a traditional CMS suggests a custom-built platform tailored for the company’s needs. While the technical stack is modern and robust, opportunities exist to improve SEO and accessibility compliance further. Hosting details are not explicitly identified, but the presence of Malta-based contact information suggests regional hosting or corporate presence.
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.
