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

ShareX is a well-established open source software project focused on providing a free, powerful screen capture and file sharing tool for Windows users. With over 17 years of active development, it holds a strong position in the productivity software market, trusted by a broad user base including power users and large companies. The website effectively communicates the product's features and benefits, supported by a consistent brand presence and active community engagement on platforms like GitHub, Discord, and Reddit. Technically, the site is built on modern web technologies including Jekyll, Bootstrap, and FontAwesome, hosted behind Cloudflare DNS services, ensuring good performance and mobile optimization. Security posture is solid with HTTPS enforced and domain transfer protections, though improvements could be made by enabling DNSSEC and adding security headers. Privacy compliance is partial; a privacy policy exists but cookie consent mechanisms are absent despite Google Analytics usage. No contact emails or phone numbers are provided, which may limit direct user support visibility. Overall, the site is professional, trustworthy, and safe for general audiences.

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

5 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

ShareX operates as an open source project with a donation-supported business model, targeting Windows users needing advanced screen capture and productivity tools. Its competitive advantage lies in being completely free, ad-free, and highly customizable with extensive upload and editing features. The project benefits from a mature development history and a strong community ecosystem, including GitHub repositories and social media channels. The lack of direct commercial sales or parent company affiliation positions ShareX as a community-driven software entity. Growth indicators include active development and multiple distribution channels such as Microsoft Store and Steam. Strategic partnerships are not explicitly identified but the project leverages popular platforms for distribution and community engagement.

Security posture

The website demonstrates a good security baseline with HTTPS and domain transfer lock status. However, the absence of DNSSEC and explicit security headers like Content-Security-Policy or X-Frame-Options represents areas for enhancement. No security or incident response policies are published, and no dedicated security contact channels are provided, which could hinder vulnerability reporting and incident management. The use of Google Analytics introduces minimal tracking but lacks a cookie consent mechanism, potentially impacting GDPR compliance. No vulnerabilities or exposed sensitive data were detected in the site content. Overall, the security posture is adequate for an open source project website but could be improved to meet higher compliance and security standards.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Implement and publish a comprehensive security policy and incident response contact information.
  3. Add explicit HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Introduce a cookie consent banner or mechanism to comply with GDPR and inform users about tracking.
  5. Provide clear contact information including support emails or forms to improve user trust and communication.

Technical notes

Notes

The website is built using the Jekyll static site generator, styled with Bootstrap and FontAwesome, and enhanced with jQuery for interactivity. It is hosted behind Cloudflare DNS services, which likely provide CDN and DDoS protection. The site loads quickly and is mobile responsive with good accessibility and SEO practices. Google Fonts are used for typography. Google Analytics is integrated for visitor tracking. No CMS vulnerabilities or outdated libraries were detected. The site architecture is modern and well-maintained, with no broken links or errors observed. Opportunities exist to improve security headers and privacy compliance mechanisms.
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.
