The site is mobile-optimized and provides a good user experience with clear navigation and responsive design. Security-wise, the website enforces HTTPS and includes GDPR-compliant cookie and personal data consent mechanisms, though it lacks some advanced HTTP security headers and published security 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

9 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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

Avente s.r.o. operates as a small-sized service provider in the technology and advertising sector, focusing on web and e-commerce development, branding, and marketing services. Their market position is strengthened by a long operational history and a portfolio of over 220 projects, indicating steady growth and client trust. The business model revolves around custom solutions tailored to client needs, targeting primarily local and regional businesses. The company leverages social media channels such as Facebook and Instagram for marketing and client engagement. The lack of visible partnerships or subsidiaries suggests a focused, independent operation. The use of modern tracking and analytics tools supports data-driven marketing strategies. Overall, the company appears well-positioned in its niche with a clear value proposition and a professional digital footprint.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS encryption and a comprehensive GDPR-compliant cookie consent mechanism that allows users to manage preferences for functional, analytical, and marketing cookies. Personal data processing is transparently disclosed with contact information for data protection inquiries. However, the absence of HTTP security headers such as Content-Security-Policy and X-Frame-Options is a notable gap that could expose the site to certain web-based attacks. No security policy or incident response contact is published, which limits transparency and preparedness in case of security incidents. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party tracking scripts is controlled via consent, aligning with privacy best practices. Overall, the security posture is good but could be enhanced by implementing additional headers and publishing formal security policies.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  2. Publish a clear security policy and incident response contact information on the website to improve transparency and preparedness.
  3. Consider creating and publishing a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Enhance accessibility features to meet recognized standards and improve user inclusivity.
  5. Regularly audit and update third-party scripts and tracking tools to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built using standard modern web technologies including HTML5, CSS3, and JavaScript with libraries such as jQuery and Slick Slider for UI components. Google Fonts are used for typography, and Google Tag Manager along with Leady tracking scripts are employed for analytics and marketing purposes. The site is mobile-responsive and optimized for good user experience. Performance is moderate, with asynchronous loading of scripts to improve page load times. No CMS or hosting provider information is explicitly detected. The site uses a custom GDPR cookie modal and personal data processing popup, indicating attention to privacy compliance. There is no evidence of technical debt or outdated libraries in the provided HTML content. Opportunities exist to improve security headers and accessibility compliance to further modernize the technical infrastructure.
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.
