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

4 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 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 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

Serpstack operates in the technology sector, focusing on API services for search engine data extraction. Its business model includes a free tier and paid subscription plans, targeting developers and enterprises requiring Google SERP data at scale. The company benefits from its affiliation with APILayer, enhancing its market credibility and resource access. The presence of affiliate programs, extensive documentation, and social media engagement indicates a mature marketing and partnership ecosystem. The domain age and WHOIS data align with the company's claimed history, supporting legitimacy. Revenue streams likely include subscription fees and affiliate commissions. The company maintains a consistent brand and offers reliable customer support.

Security posture

The website enforces HTTPS with bank-grade 256-bit SSL encryption, ensuring secure data transmission. Use of Google reCAPTCHA protects forms from automated abuse. Domain status flags such as clientDeleteProhibited enhance domain security. However, DNSSEC is not enabled, and common security headers like Content-Security-Policy and X-Frame-Options are not explicitly detected, representing areas for improvement. No vulnerabilities or exposed sensitive data were found in the analysis. Incident response and security policy pages are not publicly available, which could be a compliance gap. Overall, the security posture is good but could be enhanced by adopting additional best practices and transparency measures.

Recommendations

  1. Enable DNSSEC to improve domain name system security and prevent DNS spoofing.
  2. Implement and publish a dedicated security policy and incident response page to enhance transparency and compliance.
  3. Add and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  4. Provide explicit contact channels for security incidents, such as security@ or abuse@ email addresses.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities or outdated components are present.

Technical notes

Notes

The website uses a modern technology stack including jQuery, Google Tag Manager, Google Analytics, Stripe for payments, and Cloudflare for DNS and likely CDN services. The site is custom-built without a detectable CMS, optimized for fast loading and mobile responsiveness. Cookie consent is managed via CookieScript, indicating privacy compliance efforts. The use of affiliate tracking and marketing tools is well integrated. Performance is fast with good SEO and accessibility basics. Technical risks are minimal, but the absence of some security headers and DNSSEC could pose moderate risks. The infrastructure appears scalable and robust, suitable for high-volume API requests.
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.
