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

Mobirise Ltd operates a well-established website offering a free HTML builder software that leverages AI and drag-and-drop technology to enable users to create professional, mobile-friendly websites without coding. The company targets a broad audience including individuals, freelancers, and small businesses, positioning itself as a leading no-code website builder with over 2.5 million users. The website is technically mature, employing modern frameworks such as Bootstrap 5, and integrates popular analytics and marketing tools like Google Tag Manager and Facebook Pixel. Security posture is solid with HTTPS and domain locking, though improvements in security headers and DNSSEC are recommended. Privacy compliance is partially addressed with clear privacy and terms pages but lacks explicit cookie consent mechanisms. Overall, the site demonstrates high professionalism, trustworthiness, and business credibility.

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

7 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

Mobirise's market positioning as a free yet powerful HTML builder with AI capabilities gives it a competitive advantage in the no-code website builder space. Its business model combines free software distribution with premium extensions and templates sales. The company maintains a strong partnership ecosystem, including AI services and template marketplaces, enhancing its product offering. The presence of testimonials from credible sources and a consistent brand image supports strong customer trust and engagement. The company operates from the Netherlands and has a medium-sized footprint with a focus on technology and software development.

Security posture

The website enforces HTTPS and employs domain registration locks to prevent unauthorized changes, indicating a mature security approach. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options represents areas for enhancement. No forms on the analyzed page collect sensitive data, reducing attack surface. Tracking scripts are present without a visible cookie consent mechanism, which may pose compliance risks under GDPR. Incident response and security policy information are not publicly disclosed, suggesting room for improved transparency and readiness.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  3. Add a clear cookie consent banner/mechanism to comply with GDPR and other privacy regulations.
  4. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  5. Regularly audit third-party scripts and tracking tools to ensure privacy compliance and minimize user tracking.

Technical notes

Notes

The website is built using modern web standards including HTML5, CSS3, and JavaScript, with Bootstrap 5 as the primary framework ensuring responsive and mobile-friendly design. It uses Google Fonts for typography and integrates Google Tag Manager and Facebook Pixel for analytics and marketing. The site is hosted behind Cloudflare DNS, providing performance and security benefits. Lazy loading techniques improve performance. No CMS is detected, indicating a static or custom-built site. The site loads quickly and is well optimized for mobile devices. Technical debt appears low, but security enhancements and privacy compliance improvements are advisable.
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.
