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

ADTENDE SL is a specialized company focused on innovation and service provision for the public sector, particularly in electronic administration and citizen assistance. The company positions itself as a unique partner with a public sector DNA, offering comprehensive services such as OAC 360º, LIAM AI agent, and centralized call services. Their target audience includes public administrations and e-citizens, emphasizing effective and innovative solutions to improve public service delivery. Technically, the website is built on WordPress with Elementor and integrates modern tools like Google Analytics and reCAPTCHA, but suffers from slow performance and lacks a valid SSL certificate, which is a critical security concern. Privacy and cookie policies are well implemented and GDPR compliant, with clear contact information and social media presence enhancing business credibility. Security posture is weak due to missing HTTPS and lack of security headers, exposing the site to potential risks. Overall, the site is professional and trustworthy but requires urgent security improvements to protect user data and enhance trust.

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. 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 Policy found

      GDPR requires clear information about cookie usage

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

  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 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';…

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

ADTENDE SL operates in the government sector, delivering innovative electronic administration services and citizen assistance solutions. Their business model revolves around providing specialized support and technology-driven services to public administrations, leveraging AI and centralized communication platforms. The company maintains strong partnerships and alliances in the technology sector to support its offerings. Market positioning is strong within its niche, emphasizing a public sector origin and exclusive focus. The company targets municipalities and public entities, as evidenced by client logos and references. Revenue streams likely include service contracts and specialized assistance programs. Growth indicators include continuous service innovation and digital presence expansion. The partnership ecosystem includes technology providers and public sector clients, reinforcing their market credibility.

Security posture

The current security maturity level of ADTENDE SL's website is low due to the absence of a valid SSL certificate and HTTPS support, which is a critical vulnerability. While no immediate vulnerabilities like subdomain takeover or known SSL exploits are detected, the lack of modern TLS protocols and security headers exposes the site to risks such as data interception and man-in-the-middle attacks. GDPR compliance is supported by clear privacy and cookie policies, but no explicit security or incident response policies are published. The use of Google reCAPTCHA on forms is a positive security measure. Incident response readiness and security culture indicators are not evident from the website content. Overall, the security posture requires significant enhancement to meet industry best practices and regulatory requirements.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable deprecated versions to secure communications.
  3. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload to enforce HTTPS usage.
  4. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  5. Publish a clear security policy and incident response plan to enhance transparency and preparedness.

Technical notes

Notes

The website is built on a modern CMS platform (WordPress) using Elementor for design and layout, supported by Yoast SEO for search optimization and Google Analytics for traffic monitoring. The site integrates Google reCAPTCHA for form security and GDPR Cookie Compliance for privacy adherence. Despite these modern tools, the site suffers from slow load times (18.6 seconds) and a large page size (~2.3 MB), indicating potential optimization opportunities. The absence of a valid SSL certificate and disabled TLS protocols represent critical technical risks. Accessibility and mobile optimization are basic to good, with room for improvement in performance and security hardening. Technical debt is moderate, with outdated SSL configuration being the most pressing issue. Modernization efforts should focus on security upgrades and performance optimization to improve user experience and trust.
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.
