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

Mobirise Ltd operates a mature and reputable website builder platform focused on enabling users to create websites easily without coding, leveraging AI technology and drag-and-drop interfaces. The company targets individuals and small businesses seeking simple yet powerful website creation tools. Their business model combines a free core product with premium themes and extensions, positioning them well in the no-code website builder market with over 2.5 million users. Technically, the website uses modern frameworks like Bootstrap 5 and integrates analytics and marketing tools such as Google Tag Manager and Facebook Pixel. The domain is well-registered and protected, hosted behind Cloudflare DNS, and the website is mobile-optimized with excellent design and user experience. Security posture is good with HTTPS and domain locks, but could be improved by enabling DNSSEC and publishing explicit security policies. Privacy compliance is adequate with a clear privacy policy and terms of service, though cookie consent mechanisms are lacking. Overall, Mobirise presents a professional, trustworthy, and technically sound platform with room for incremental security and privacy enhancements.

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

    • 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 holds a strong market position as a freemium no-code website builder with AI capabilities, appealing to a broad audience including non-technical users and freelancers. Their extensive template library, e-commerce integrations, and social media features provide competitive advantages. Revenue streams likely include premium themes, extensions, and possibly AI-powered services. The company maintains a consistent brand presence and leverages partnerships such as with electricblaze.com for payment processing. Growth indicators include a large user base and continuous product updates. The ecosystem is supported by active social media channels and community forums, enhancing user engagement and support.

Security posture

The website demonstrates a solid security foundation with HTTPS encryption, domain registration protections, and use of reputable DNS providers. However, the absence of DNSSEC and HTTP security headers represents potential areas of vulnerability. No explicit security or incident response policies are published, which may impact transparency and readiness. Tracking scripts are present without visible cookie consent, posing privacy compliance risks under GDPR. No known vulnerabilities or exposed sensitive data were detected. Overall, the security maturity is good but could benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and publish HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options.
  3. Add a cookie consent banner/mechanism to comply with GDPR and other privacy regulations.
  4. Publish a dedicated security policy and provide clear incident response contact information.
  5. Regularly audit third-party scripts and dependencies to mitigate potential vulnerabilities.

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 design and mobile optimization. Google Fonts and video content enhance user experience. Analytics and marketing integrations include Google Tag Manager and Facebook Pixel, enabling user behavior tracking and retargeting. Hosting utilizes Cloudflare DNS for performance and security benefits. The site loads quickly and is well-structured for SEO. No CMS is detected, indicating a static site generation approach via the Mobirise desktop and AI builder apps. Technical risks are minimal but include lack of DNSSEC and missing security headers which should be addressed to reduce attack surface.
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.
