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

Movistar Prosegur Alarmas is a joint venture brand offering advanced alarm and security systems for homes and businesses in Spain. The company leverages the strong brand recognition of Movistar and Prosegur to provide comprehensive security solutions including installation, monitoring, and emergency response services. The website is professionally designed, targeting B2C customers seeking reliable security products with a focus on ease of contracting and customization. Technically, the website uses a modern tech stack including Magnolia CMS, Google Tag Manager, Taboola for advertising, and Didomi for consent management. The site is mobile optimized and implements cookie consent mechanisms compliant with GDPR. Performance is moderate with good SEO and accessibility basics in place. From a security perspective, the site enforces HTTPS and uses secure forms with CSRF tokens. While explicit security headers are not fully confirmed, no vulnerabilities or exposed sensitive data were detected. The privacy and cookie policies are comprehensive and clearly presented, supporting GDPR compliance. However, no explicit security policy or incident response information is found. Overall, the website presents a trustworthy and professional front for a large telecommunications and security business. The lack of WHOIS data limits full domain legitimacy verification, but the branding and content strongly indicate a legitimate and established operation. Strategic recommendations include enhancing security headers, maintaining third-party script audits, and publishing explicit security and incident response policies.

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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  2. 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

The company operates in the telecommunications sector, focusing on security alarm systems for residential and commercial customers in Spain. Its business model centers on direct sales with installation and monitoring services, targeting consumers who value high security with guarantees against theft and occupation. The partnership between Movistar and Prosegur provides competitive advantages through brand trust and combined expertise. The website supports growth by offering customizable alarm packages and easy contracting options. The presence on major social media platforms and use of marketing tools like Taboola indicate an active digital marketing strategy. No subsidiaries or parent company details are explicitly stated, but the brand positioning suggests a large enterprise scale.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS, secure form handling, and GDPR-compliant cookie consent. No critical vulnerabilities or exposed sensitive information were found in the HTML content. The use of Didomi for consent management and Google Tag Manager for analytics is standard practice. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options is a minor gap. No dedicated security policy or incident response contact information is published, which could be improved to enhance transparency and readiness. Overall, the site is secure for typical user interactions but could benefit from additional security hardening and documentation.

Recommendations

  1. Implement and verify comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Maintain transparency on data retention policies and provide detailed privacy notices.

Technical notes

Notes

The website is built on Magnolia CMS, utilizing modern JavaScript libraries and frameworks such as Bootstrap 4 and jQuery. It integrates multiple third-party services including Google Tag Manager for analytics, Taboola for advertising and retargeting, and Didomi for consent management. The site is mobile responsive with good SEO practices including meta tags and structured data in JSON-LD format. Performance is moderate, with some preloading of fonts and scripts to optimize loading times. The technical infrastructure supports a professional and scalable online presence, though hosting provider details are not explicitly identified. Opportunities exist to improve security headers and accessibility compliance.
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.
