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

SMARTSTREAM.TV GmbH is a well-established digital media marketer operating primarily in the DACH region, specializing in upper funnel advertising solutions including video ads, engagement ads, and reach optimization. The company is part of the ProSiebenSat.1 Media SE group, which strengthens its market position and credibility. Their website demonstrates a high level of professionalism, with comprehensive service descriptions and multiple office locations across Germany, Austria, and Switzerland. Technically, the site uses modern web frameworks such as Next.js and React, ensuring good performance and mobile optimization. Security posture is solid with HTTPS enforced, though some security headers and explicit incident response policies are not visible. Privacy compliance is good with a comprehensive privacy policy, but a cookie consent mechanism is missing. Overall, the website and business present a trustworthy and professional image, though the absence of WHOIS data slightly reduces domain trust.

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.

    • 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

  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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • 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
  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Unregistered MX Record

      MX record points to unregistered domain: exchange.smartstream.tv

      What to do: Remove or fix MX record pointing to unregistered domain

      • RFC 5321 §5.1
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory

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 company targets advertisers and marketers in the DACH region seeking advanced video advertising solutions. Their business model revolves around providing digital advertising services with a focus on video branding, engagement, and reach. The firm leverages its affiliation with ProSiebenSat.1 Media SE to enhance market reach and trust. Revenue streams likely include media buying, creative services, and research insights. The presence of multiple offices and country managers indicates a medium-sized enterprise with regional coverage. The company emphasizes innovation and technology in digital advertising, positioning itself as a leader in upper funnel marketing solutions.

Security posture

The website enforces HTTPS and avoids exposing sensitive data, indicating a baseline secure posture. However, the absence of common security headers such as Content-Security-Policy, X-Frame-Options, and others suggests room for improvement. No visible vulnerability disclosures or incident response contacts are provided, which could hinder rapid response to security incidents. Privacy policies are comprehensive and GDPR compliant, but cookie consent mechanisms are lacking, which may pose compliance risks. Overall, the security maturity is moderate with good foundational practices but missing advanced controls and transparency.

Recommendations

  1. Implement and publish a security.txt file to facilitate vulnerability reporting.
  2. Add and enforce security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Introduce a cookie consent banner/mechanism to comply fully with GDPR cookie requirements.
  4. Publish an incident response policy and provide dedicated security contact channels.
  5. Regularly audit and update WHOIS information to ensure transparency and trust.

Technical notes

Notes

The website is built on a modern technology stack including Next.js and React, supported by a headless CMS (Strapi) inferred from URL patterns. The site is well-optimized for performance and mobile devices, with responsive design and efficient asset loading. SEO practices are good with proper meta tags and Open Graph data. Accessibility is addressed reasonably well. No major technical debt or outdated libraries are evident. Hosting provider details are not explicitly found. Overall, the technical infrastructure supports a robust and scalable digital presence.
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.
