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

CaptureKit is a technology company providing a Screenshot API service designed to automate website screenshots at scale. The platform targets developers and businesses requiring reliable, scalable screenshot capture with features such as ad and overlay removal, full-page capture, and direct cloud storage integration. The website demonstrates a strong market position with over 1,300 developers trusting the service and community recognition as a leader in its niche. Technically, the site is built on modern frameworks like Next.js and React, hosted on AWS, and integrates marketing and analytics tools such as HubSpot and Google Analytics. Security posture is robust with HTTPS, security headers, and encrypted data infrastructure, although explicit privacy and cookie policies are missing from the visible content. Overall, the site is professional, fast, and mobile-optimized, but could improve transparency on privacy and incident response.

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

  3. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

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

CaptureKit operates in the technology sector, offering API services for automated website screenshots. Its business model is SaaS with free trial credits and paid plans. The company leverages partnerships with platforms like Zapier for no-code integrations, enhancing its appeal to a broad developer audience. Testimonials and community rankings indicate a positive market reputation. The company focuses on developer-first features, enterprise readiness, and global scalability. Revenue streams likely include subscription fees and enterprise contracts. The absence of detailed company registration or physical address information limits deeper business intelligence insights.

Security posture

The website exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and AWS-based encrypted infrastructure. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. However, the lack of a published security policy, incident response contacts, or vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. Compliance with GDPR is implied but not explicitly documented. The use of third-party marketing and analytics scripts introduces moderate tracking but no overt privacy risks were identified. Overall, the security posture is strong but could benefit from enhanced policy disclosures and incident response preparedness.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Implement a visible vulnerability disclosure or security.txt page to encourage responsible reporting.
  3. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  4. Regularly review and audit third-party scripts to minimize tracking and potential vulnerabilities.
  5. Enhance transparency by disclosing data protection officer contact information and compliance certifications.

Technical notes

Notes

The website is built using modern web technologies including Next.js and React, styled with Tailwind CSS, and hosted on AWS infrastructure ensuring scalability and performance. It integrates multiple third-party services such as HubSpot for marketing automation and Google Tag Manager for analytics. The site is mobile-optimized with responsive design and fast loading times. Security headers and HTTPS are properly configured, contributing to a secure browsing experience. No CMS was detected, indicating a custom or framework-based build. Technical risks are minimal but reliance on multiple external scripts requires ongoing monitoring to prevent supply chain vulnerabilities.
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.
