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

8 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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';…

  3. 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

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

The business operates in the technology sector, focusing on digital image optimization tools. Its competitive advantage lies in offering a free, easy-to-use service with support for multiple image formats and batch processing. The business model relies on ad revenue rather than direct sales or subscriptions. The lack of direct contact information and limited privacy compliance features suggest a lean operational structure. The company appears to maintain a modest market position as a niche utility service with a long domain history indicating stability.

Security posture

The website employs HTTPS, ensuring encrypted communications, but lacks advanced security headers such as Content-Security-Policy or X-Frame-Options. No DNSSEC is enabled for the domain, which could improve DNS security. There is no published security policy or incident response information, and no vulnerability disclosure or security.txt file was found. The absence of cookie consent mechanisms and limited privacy compliance features indicate room for improvement in regulatory adherence. Overall, the security posture is basic but functional for a low-risk service.

Recommendations

  1. Enable DNSSEC to enhance domain name system security.
  2. Implement standard security headers to protect against common web vulnerabilities.
  3. Add a cookie consent banner and detailed cookie policy to improve privacy compliance.
  4. Publish a security policy and incident response contact information to build trust.
  5. Consider adding verified contact information to improve business credibility and user trust.

Technical notes

Notes

The site uses a modern JavaScript-based frontend with HTML5 and CSS3, leveraging Google Adsense for monetization and Matomo for analytics. No CMS or major frameworks were detected, indicating a custom or lightweight implementation. Performance is moderate with good mobile responsiveness and basic accessibility features. The site could benefit from enhanced SEO metadata and improved security configurations. Hosting appears to be managed via NameCheap DNS servers, consistent with the domain registrar. Overall, the technical infrastructure is adequate for the service offered but could be modernized for better security and performance.
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.
