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

PIA Proxy operates as a commercial residential proxy service provider, offering a vast pool of over 350 million residential IP addresses globally. Their services cater primarily to businesses and developers requiring anonymous, secure, and geographically targeted proxy solutions for applications such as web scraping, AI data collection, ad verification, and market research. The company positions itself as a market leader with a strong emphasis on ethical sourcing and compliance with data protection regulations. Technically, the website employs modern JavaScript frameworks like Vue.js, integrates multiple analytics and marketing tools, and supports multi-platform client applications. Security-wise, the site enforces HTTPS with HSTS but lacks some advanced security headers and cookie consent mechanisms. The absence of WHOIS data for the domain raises concerns about domain legitimacy, although the website content and structure suggest a professional and established business. Overall, the site demonstrates good digital maturity with room for improvement in privacy compliance and domain transparency.

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 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';…
  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

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

PIA Proxy's market positioning as the world's largest commercial Socks5 residential proxy provider gives it a competitive advantage in scale and geographic coverage. Their business model includes pay-per-IP and pay-per-GB pricing, appealing to diverse customer needs. The company targets sectors requiring large-scale data acquisition and anonymity, including AI, advertising, social media, and e-commerce. Partnerships with payment processors like Adyen and use of trusted analytics platforms indicate a mature operational ecosystem. However, the lack of publicly available WHOIS data and direct contact details may hinder trust for some customers. The multilingual website and extensive documentation support global reach and customer onboarding.

Security posture

The website demonstrates a solid security posture with mandatory HTTPS and HSTS headers, integration of Google reCAPTCHA for user registration, and OAuth login options via Google and Apple. However, it lacks several recommended security headers such as Content-Security-Policy and X-Frame-Options, which could enhance protection against common web attacks. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a published security policy or incident response contact reduces transparency. Privacy compliance is partial, with a privacy policy present but no visible cookie consent mechanism. Overall, the security maturity is good but could be improved with additional headers and clearer security governance disclosures.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Referrer-Policy to strengthen web security.
  2. Add a visible cookie consent banner to comply fully with GDPR and other privacy regulations.
  3. Publish a dedicated security policy page and provide clear incident response contact information to improve transparency and trust.
  4. Investigate and resolve the missing WHOIS data issue to enhance domain legitimacy and customer confidence.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are in use and maintain secure integrations.

Technical notes

Notes

The website uses a modern tech stack with Vue.js for frontend interactivity, jQuery for legacy support, and Swiper.js for UI components. It integrates multiple analytics and marketing tools such as Google Analytics, Microsoft Clarity, and Google Tag Manager, indicating a data-driven approach to user engagement. The site supports multiple platforms with dedicated client applications for Windows, Mac, Linux, Android, and iOS, reflecting a mature product ecosystem. Performance is moderate with good mobile optimization and SEO practices. However, accessibility features appear basic and could be enhanced. Hosting provider details are not explicitly identified. Overall, the technical infrastructure supports scalability and diverse user needs but could benefit from improved accessibility and security enhancements.
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.
