Risk levelLow

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

Acierto.com is an online Spanish-language platform specializing in the comparison of insurance, loans, and mortgage products. It targets Spanish consumers seeking to save money by comparing financial products. The website is professionally designed with good mobile optimization and SEO practices. Technically, it employs modern JavaScript libraries, Google Tag Manager, Cookiebot for consent management, and New Relic for performance monitoring. Security posture is generally good with HTTPS enforced and consent mechanisms in place, but lacks visible security headers and explicit privacy or terms of service pages. The absence of WHOIS data for the domain raises concerns about domain registration legitimacy, which impacts overall trustworthiness. Contact information is not explicitly found, limiting direct communication channels. Overall, the site is functional and professional but would benefit from enhanced transparency and security disclosures.

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

2 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 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. 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 business operates in the finance sector, providing a comparison service for insurance and loan products, likely generating revenue through affiliate partnerships or lead generation. The target audience is Spanish-speaking consumers in Spain. The platform's market position appears established given the professional presentation and client logos displayed. The business model focuses on digital comparison services, leveraging online traffic and user engagement. There is no evidence of parent or subsidiary companies from the data. The company demonstrates moderate digital maturity with tracking and consent tools but lacks some compliance documentation publicly visible.

Security posture

The website enforces HTTPS and uses modern monitoring tools like New Relic, indicating a baseline security awareness. However, the lack of detected security headers such as Content Security Policy, HSTS, or X-Frame-Options suggests room for improvement. No vulnerabilities or exposed sensitive data were identified in the content. The absence of explicit privacy policies, incident response contacts, or vulnerability disclosure mechanisms indicates gaps in compliance and security transparency. The domain's missing WHOIS data is a notable risk factor, potentially indicating privacy protection or registration issues. Overall, the security posture is moderate but requires enhancements to meet best practices and regulatory compliance.

Recommendations

  1. Publish comprehensive privacy policy and terms of service pages accessible from the homepage.
  2. Implement and verify HTTP security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Provide clear contact information including company emails and phone numbers for customer support and incident response.
  4. Conduct a WHOIS record audit to ensure domain registration transparency and legitimacy.
  5. Enhance accessibility compliance and provide explicit GDPR compliance statements.

Technical notes

Notes

The website uses a modern JavaScript stack with Google Tag Manager and Cookiebot for analytics and consent management, and New Relic for performance monitoring. The HTML and CSS are well structured with responsive design for mobile devices. Performance is moderate with asynchronous script loading. No CMS or hosting provider information was detected. The site lacks some advanced accessibility features and security headers. SEO meta tags and Open Graph tags are properly implemented, supporting good search engine visibility and social sharing. Overall, the technical infrastructure is solid but could benefit from security and compliance improvements.
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.
