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

Stockio.com is a free stock media platform offering a wide variety of downloadable vectors, photos, icons, fonts, and videos for personal and commercial use without attribution requirements. The site targets graphic designers, content creators, and marketers seeking high-quality free resources. It operates with a business model likely supported by advertising and user accounts for tracking downloads and favorites. Technically, the website uses modern JavaScript frameworks, Amazon Cloudfront CDN, and Ezoic ad optimization, delivering moderate performance and good mobile responsiveness. Security posture is solid with HTTPS enforced and cookie consent mechanisms in place, though it lacks explicit security headers and incident response contacts. The absence of WHOIS registration data raises some legitimacy concerns, but the professional content and compliance with privacy regulations mitigate these risks. Overall, the site presents a trustworthy and useful resource for free stock media.

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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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

Stockio positions itself in the competitive free stock media market, differentiating by offering a broad range of media types and a user account system for personalized tracking. The company appears small but focused on media content delivery, leveraging partnerships with ad networks like Ezoic and Google Adsense for monetization. Its social media presence on Facebook, Twitter, and Instagram supports community engagement. The lack of detailed business registration information and phone contacts suggests a lean operation primarily online. Growth potential exists through content expansion and enhanced user engagement features.

Security posture

The website demonstrates a moderate security maturity level with HTTPS and GDPR-compliant cookie consent. However, it lacks several best practices such as security headers (CSP, HSTS), a published security policy, incident response contacts, and a vulnerability disclosure program. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of multiple third-party scripts introduces potential risk vectors that should be regularly audited. Overall, the security posture is adequate for the business type but could be improved to enhance trust and resilience.

Recommendations

  1. Implement and enforce security headers including Content Security Policy, HSTS, and X-Frame-Options.
  2. Publish a security policy and provide clear incident response contact information.
  3. Add a security.txt file to facilitate vulnerability disclosures.
  4. Conduct regular security audits of third-party scripts and dependencies.
  5. Enhance accessibility features to improve compliance and user experience.

Technical notes

Notes

The website uses a modern JavaScript-based front end with Go templating, Amazon Cloudfront CDN for content delivery, and Ezoic for ad optimization and analytics. Performance is moderate with room for improvement in loading speed and accessibility. SEO is well addressed with proper meta tags and Open Graph data. The site is mobile optimized and uses cookie consent mechanisms to comply with privacy regulations. There is no detected CMS, suggesting a custom or static site architecture. Technical risks include reliance on multiple third-party scripts and lack of explicit security headers.
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.
