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

ZenRows is a technology company specializing in providing a next-generation web scraping API designed to avoid blocking by using rotating proxies and advanced anti-bot bypass techniques. The company targets developers, data engineers, and businesses requiring reliable data extraction infrastructure. Their market position is that of a specialized, reliable service provider with a high success rate and a customer base of over 2,000 companies. The website demonstrates a modern technical infrastructure with use of React-like SPA frameworks, integration of analytics tools such as Microsoft Clarity and Visual Website Optimizer, and customer support via Intercom. Security posture is generally good with HTTPS enforced and no visible vulnerabilities, but lacks publicly disclosed security policies or incident response contacts. Privacy compliance is weak due to absence of privacy and cookie policies or consent mechanisms. Overall, the site is professional and trustworthy from a content and technical perspective, but domain registration data is missing, which reduces trust from a domain legitimacy standpoint.

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

7 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 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

    • 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

ZenRows operates in the technology sector, offering web scraping infrastructure as a service. Their business model is API-based SaaS, focusing on providing scalable, reliable data extraction solutions with proxy rotation and anti-bot features. The company appears to have a small size with a focused product offering. Their competitive advantage lies in high success rates and ease of integration with existing data stacks. The website content and branding are consistent and professional, targeting technical users and businesses. The lack of visible company registration or contact details limits transparency. The partnership ecosystem is not explicitly detailed, and no related or subsidiary domains were identified.

Security posture

The website enforces HTTPS and uses modern security best practices, including proxy rotation and anti-bot bypass for its core service. However, it lacks publicly available security policies, incident response contacts, or vulnerability disclosure programs. No security.txt file or DPO contact information is found. Analytics and marketing tools are used extensively, which may increase privacy risks if not properly managed. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of explicit security headers beyond HTTPS is a minor gap. Overall, the security posture is moderate but could be improved with transparency and formal policies.

Recommendations

  1. Publish comprehensive privacy and cookie policies with GDPR compliance details.
  2. Implement and display a cookie consent mechanism to comply with privacy regulations.
  3. Provide a public security policy and incident response contact information.
  4. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Ensure WHOIS domain registration data is complete and publicly accessible to improve trust.

Technical notes

Notes

The website uses a modern JavaScript stack with SPA characteristics, Google Fonts, and integrates multiple third-party analytics and marketing tools such as Microsoft Clarity, VWO, and Intercom.

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.
