Risk levelHigh

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

The website prosilia.se is a domain sales landing page operated by NVA Online Advertising B.V., a Dutch company specializing in domain brokerage and escrow services since 2004. The platform offers a safe and fast way to purchase domain names, emphasizing escrow to protect buyers and sellers. The site is hosted on a CDN and built with modern web technologies including SvelteKit, providing a fast and mobile-optimized user experience. However, the content is limited to domain sale information and lacks comprehensive privacy or security policies. Security posture is moderate with no visible security headers or incident response contacts, but no critical vulnerabilities were detected. Overall, the site is legitimate and professional but could improve privacy compliance and security transparency.

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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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. 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  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

NVA Online Advertising B.V. operates as a domain reseller and escrow service provider targeting individuals and businesses seeking domain names. Their business model relies on facilitating domain transactions with no fees to buyers, generating revenue from seller commissions. The company positions itself as a trustworthy intermediary with fast transfer times and VAT invoicing. The partnership with nameshift.com is central to their operations, providing the platform and payment processing. The company is small-sized, established in 2004, and operates primarily in the Netherlands. The presence of Trustpilot reviews and VAT information supports credibility. Growth opportunities include expanding marketing transparency and adding more direct contact channels.

Security posture

The website demonstrates a basic security posture with HTTPS assumed but not explicitly confirmed in the HTML. No security headers such as Content-Security-Policy or X-Frame-Options were detected, and no explicit security or incident response policies are published. The escrow service model mitigates transactional risk, which is a positive security practice. No exposed sensitive data or vulnerable libraries were found. The lack of privacy and cookie policies indicates compliance gaps with GDPR and related regulations. Incident response readiness is unclear due to missing contact channels. Overall, security maturity is moderate but could be significantly improved by adding formal policies, security headers, and incident response information.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add explicit incident response and abuse contact information on the website.
  4. Enhance accessibility features to improve compliance and user experience.
  5. Ensure HTTPS enforcement and display security indicators prominently.

Technical notes

Notes

The website is built using the SvelteKit framework, leveraging modern JavaScript and CSS with module preloading for performance optimization. Hosting is via a CDN associated with nameshift.com, ensuring fast content delivery. The site is mobile optimized and uses external widgets such as Trustpilot for reviews and a tracking script from stats.nameshift.com for analytics. No CMS was detected, indicating a custom or framework-based site. The technical implementation is modern and performant, though accessibility could be improved. No technical debt or legacy technologies were observed. The site lacks some SEO metadata beyond basic description and title tags but maintains good structure and navigation clarity.
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.
