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

Probiller operates as a secure online payment gateway service provider, facilitating millions of transactions monthly for innovative eCommerce businesses globally. The company supports a broad range of payment methods including credit cards, eWallets, and bank transfers, and offers 24/7 multilingual customer support. Their market position is that of an industry leader with a focus on compliance and security. Technically, the website employs modern frontend technologies such as jQuery, Bootstrap, and Owl Carousel, and integrates a third-party chat widget for customer support. The site is mobile responsive and well-structured, though some accessibility features could be improved. No major performance issues were detected, but security headers and explicit cookie consent mechanisms are lacking. From a security perspective, the site uses HTTPS and avoids exposing sensitive data visibly. However, the absence of WHOIS registration data raises concerns about domain legitimacy and trustworthiness. No explicit security policies or incident response contacts are published, which could be improved to enhance transparency and compliance. Overall, the website presents a professional and functional front for Probiller's payment services but would benefit from enhanced security practices, privacy compliance improvements, and clearer domain registration transparency to strengthen trust and reduce risk.

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

6 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 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

Probiller targets eCommerce businesses requiring secure and versatile payment processing solutions. Their competitive advantage lies in supporting multiple international payment methods and providing 24/7 multilingual customer service. The business model centers on payment gateway services with revenue likely derived from transaction fees and partnerships. The company maintains a global presence with offices in the US and Cyprus, indicating a medium-sized operation. The partnership ecosystem includes integration with various eCommerce platforms, though no explicit partner domains were identified. Growth indicators include a broad service offering and active social media engagement. Strategically, Probiller should focus on enhancing transparency around domain registration and security policies to build greater customer confidence and comply with evolving regulatory requirements.

Security posture

Probiller demonstrates a moderate security maturity level with HTTPS usage and secure payment processing claims. The website avoids exposing sensitive data and integrates secure chat support. However, the lack of security headers, absence of published security policies, and missing incident response contacts indicate gaps in security governance. The missing WHOIS data is a significant red flag that undermines domain trustworthiness. Compliance with GDPR and other data protection regulations is only partially evidenced by the presence of a privacy policy but lacks cookie consent mechanisms and explicit data protection officer contact. The business impact of these gaps includes potential reputational risk and regulatory scrutiny. Enhancing security policies, publishing incident response contacts, and implementing comprehensive privacy compliance measures are recommended to improve security posture and customer trust.

Recommendations

  1. Implement and enforce HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a detailed security policy and incident response contact information on the website.
  3. Introduce a cookie consent banner/mechanism to comply with GDPR and other privacy regulations.
  4. Investigate and resolve the missing WHOIS registration data to improve domain legitimacy and trust.
  5. Enhance accessibility features to meet recognized standards and improve user experience for all visitors.

Technical notes

Notes

The website is built using a modern frontend stack including jQuery, Bootstrap for responsive grid layout, Owl Carousel for sliders, and Font Awesome for icons. It integrates a third-party chat widget from Five9 for customer support. The site is mobile optimized and has a clear navigation structure. However, no CMS or backend platform was detected from the HTML content. Hosting provider details are not disclosed. Performance appears moderate with no obvious delays or errors. Technical debt is minimal on the frontend, but the absence of security headers and privacy compliance mechanisms indicates areas for modernization and risk mitigation.
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.
