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. 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
    • 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

Przelewy24 operates in the competitive online payment processing market in Poland, leveraging partnerships and integrations with major payment methods and marketing platforms. Its business model focuses on providing seamless payment solutions to online merchants, enhancing customer experience and conversion rates. The company benefits from strong brand recognition and trust signals such as privacy policies and cookie consent. The presence of partner domains like erecruiter.pl suggests a broader ecosystem engagement. Growth indicators include extensive use of analytics and marketing tools, positioning Przelewy24 as a key player in the regional fintech landscape.

Security posture

The website exhibits a good security maturity level with HTTPS encryption and cookie consent compliance. However, the absence of visible security headers like Content-Security-Policy and X-Frame-Options suggests room for enhancement. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a public security policy or incident response contact limits transparency in security incident handling. Compliance with GDPR is evident through detailed privacy and cookie policies. Overall, the security posture is adequate for a financial service provider but could be strengthened by adopting additional best practices and publishing vulnerability disclosure information.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response page including contact channels for reporting vulnerabilities or abuse.
  3. Introduce a security.txt file to facilitate responsible vulnerability disclosure and improve transparency.
  4. Enhance contact information availability, including verified company emails and phone numbers for customer and security inquiries.
  5. Regularly audit third-party scripts and cookies to ensure compliance with privacy regulations and minimize tracking risks.

Notes

The website uses a modern tech stack including JavaScript, Google Tag Manager, and Cookiebot for consent management. It loads multiple external scripts asynchronously to optimize performance. The site is mobile optimized with responsive design and accessibility features. SEO is supported by proper meta tags and Open Graph data. Hosting provider details are not explicitly found. Performance is moderate with potential for improvement by optimizing third-party script loading. No CMS was detected from the HTML content. Overall, the technical infrastructure supports a professional and user-friendly online payment platform.
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.
