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. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

Sulvo operates in the technology sector, focusing on digital advertising and publisher monetization. Their business model is B2B SaaS, offering specialized ad serving and optimization tools that integrate with major ad networks and programmatic platforms. The company leverages advanced features such as bot scoring, super-auctions, and custom ad formats to differentiate itself. Market positioning is niche but important for publishers facing revenue loss due to ad-blocking. The presence of a Google Certified Publisher badge and detailed case studies indicates a credible and growth-oriented business. However, the lack of direct contact details and privacy documentation may limit trust for some clients. The company appears to be small-sized with a domain age consistent with a mature startup or SME. No parent or subsidiary relationships were identified.

Security posture

The website employs HTTPS and has domain status protections to prevent unauthorized changes, indicating a baseline security posture. However, there is no evidence of DNSSEC, security headers, or published security policies, which are best practices for modern web security. The absence of vulnerability disclosure or incident response information reduces transparency and preparedness perception. External scripts include third-party ad and tracking services, which may introduce risk if not properly managed. No critical vulnerabilities or exposed sensitive data were detected in the content. Overall, the security posture is moderate but could be significantly improved by implementing and publishing security controls and policies.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy with consent mechanisms to improve GDPR compliance.
  2. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  3. Add security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-Content-Type-Options.
  4. Publish a security policy and incident response contact information to increase transparency and trust.
  5. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.

Technical notes

Notes

The website is built using modern front-end technologies including Vue.js and Tailwind CSS, providing a responsive and visually appealing user experience. It integrates multiple external scripts for analytics and ad serving, such as Google Tag Manager and Demand Supply. The domain is registered with Amazon Registrar and uses Cloudflare DNS, indicating reliable hosting infrastructure. Performance is moderate with preloading of scripts and assets, though no explicit performance metrics were available. Accessibility features are basic but present. SEO is supported by proper meta tags and Open Graph data. The site lacks CMS indicators, suggesting a custom-built SPA. Overall, the technical implementation is solid but could benefit from enhanced security configurations and privacy compliance features.
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.
