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. 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. 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 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

Nordecon leverages its established market position in construction and real estate to develop Seileri Kvartal, a large-scale residential project with 133 apartments and commercial spaces. The business model focuses on property development and sales, targeting families and vacation home buyers in Pärnu. The project benefits from a prime location with river views and proximity to city amenities, enhancing its market appeal. The website supports marketing and lead generation through integrated analytics and retargeting tools. The absence of direct contact info on the site suggests lead capture may be handled via forms or offline channels. The project aligns with Nordecon's growth strategy in residential real estate, supported by consistent branding and quality content.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and a cookie consent mechanism that respects user privacy and GDPR requirements. No security.txt or incident response information is published, which could improve transparency and readiness. The lack of DNSSEC and security headers like CSP or X-Frame-Options indicates room for enhancement. No exposed sensitive data or vulnerable libraries were detected. The use of third-party analytics and marketing scripts introduces moderate tracking but is managed with user consent. Overall, the site is secure for its purpose but would benefit from additional security policies and technical controls.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a terms of service page and a dedicated security policy to enhance legal compliance and user trust.
  4. Add explicit contact information including company emails and phone numbers for better user support and transparency.
  5. Consider publishing a security.txt file and incident response contact details to improve security communication.

Technical notes

Notes

The website is built on a CMS platform likely Voog, with integration of Google Analytics, Google Tag Manager, Facebook Pixel, and Google Maps API for enhanced functionality and marketing. The site uses modern JavaScript libraries and CSS for responsive design and interactive features like image comparison sliders. Performance is moderate with asynchronous loading of scripts. SEO is supported by proper meta tags and Open Graph data. Accessibility is basic but could be improved with more ARIA roles and keyboard navigation support. Hosting is provided by Zone Media OÜ, a reputable Estonian provider. Overall, the technical infrastructure is solid but can be optimized further for security and accessibility.
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.
