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 worldwide. The company emphasizes security, compliance, and multilingual 24/7 customer support, positioning itself as an industry leader in payment processing. The website content reflects a professional and customer-focused approach with clear service descriptions and multiple contact channels. Technically, the website employs modern web technologies including jQuery, Bootstrap, Owl Carousel, and integrates a third-party chat widget for customer support. The site is mobile optimized with good navigation and SEO practices, though some accessibility features could be improved. Security best practices are partially implemented, with HTTPS implied but no explicit security headers detected in the HTML source. From a security perspective, the absence of WHOIS data and lack of cookie consent mechanisms are notable gaps that impact trust and privacy compliance. However, no critical vulnerabilities or exposed sensitive data were found. The site maintains a safe content rating with no adult or questionable material. Overall, Probiller presents a credible and professional online presence with room for improvement in transparency, privacy compliance, and security hardening to enhance trust and regulatory adherence.

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 the global eCommerce market by providing a comprehensive payment gateway solution supporting multiple payment methods and currencies. Its business model centers on facilitating secure online transactions for partner merchants, generating revenue likely through transaction fees and service subscriptions. The company maintains a multilingual 24/7 customer support infrastructure, enhancing customer satisfaction and retention. Social media engagement and clear contact information support brand visibility and trust. The lack of public WHOIS data is unusual for a payment processor and may warrant further investigation. The company operates under Aylo Billing US Corp., with physical presence in the US and Cyprus, indicating an international operational footprint.

Security posture

The website demonstrates a moderate security posture with HTTPS usage and integration of secure payment technologies. However, the absence of visible security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces defense-in-depth. No explicit security or incident response policies are published, and no vulnerability disclosure or security.txt files are present. The chat widget is a third-party service, which may introduce additional risk vectors if not properly managed. Privacy compliance is partial, lacking cookie consent mechanisms and GDPR indicators. Overall, the security maturity is adequate but could be significantly improved by implementing standard web security headers, publishing security policies, and enhancing privacy controls.

Recommendations

  1. Implement and enforce standard security headers (CSP, HSTS, X-Frame-Options) to improve web security posture.
  2. Publish explicit security and incident response policies to enhance transparency and trust.
  3. Add a cookie consent banner and detailed cookie policy to comply with privacy regulations such as GDPR.
  4. Conduct regular security audits of third-party integrations, especially chat and payment processing components.
  5. Improve accessibility features to broaden user inclusivity and comply with standards.

Technical notes

Notes

The website uses a modern front-end stack with Bootstrap for responsive design, jQuery for DOM manipulation, Owl Carousel for sliders, and Font Awesome for icons. The integration of the Five9 chat widget provides real-time customer support. The site is mobile optimized and SEO friendly with proper meta tags and structured navigation. However, no CMS or hosting provider information is evident. Performance appears moderate with no major issues detected. The lack of explicit security headers and cookie consent mechanisms indicates technical debt in security and privacy compliance areas. Opportunities exist to modernize security practices and enhance accessibility.
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.
