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

4 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

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

Streamdiver positions itself as an innovative player in the AI-driven content marketing space, focusing on B2B teams that require efficient content management and strategic insights. Its SaaS business model is subscription-based with flexible pricing tailored to team size and use cases. The company leverages partnerships and funding from Austrian agencies (FFG, KWF) and showcases reputable customer logos to build trust. The platform's competitive advantage lies in its semantic content understanding and generative AI capabilities, differentiating it from traditional DAM or content hubs. Growth indicators include a user base of 20k marketing users and high customer satisfaction ratings. The company targets medium-sized enterprises in German-speaking markets with plans for internationalization via English language support.

Security posture

Streamdiver demonstrates a solid security posture with mandatory HTTPS, clientTransferProhibited domain status, and cookie consent mechanisms aligned with GDPR. However, the absence of DNSSEC and explicit security headers such as X-Frame-Options or Content-Security-Policy in the HTML source are areas for improvement. No incident response or vulnerability disclosure policies are publicly available, which could impact trust for security-conscious customers. No exposed sensitive data or vulnerable libraries were detected. The platform should consider publishing a security policy and incident response contacts to enhance transparency and readiness. Overall, the security maturity is good but can be elevated with additional controls and documentation.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Implement and publish explicit security headers like X-Frame-Options and X-Content-Type-Options.
  3. Publish a formal security policy and incident response contact information on the website.
  4. Add a security.txt file to facilitate responsible vulnerability disclosures.
  5. Consider providing direct company contact emails or phone numbers for improved customer trust.

Technical notes

Notes

The website is built on Webflow CMS, hosted via Cloudflare, and uses modern web technologies including Google Fonts and asynchronous JavaScript loading for performance optimization. The site is mobile responsive with excellent design and navigation clarity. Analytics are implemented via Google Tag Manager, and cookie consent is managed by Cookiebot, ensuring GDPR compliance. The use of Storylane for interactive demos enhances user engagement. Performance is fast with no broken elements detected. Technical risks are minimal, though the lack of DNSSEC and some security headers represent minor technical debt. Overall, the technical infrastructure supports a scalable, secure, and user-friendly SaaS platform.
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.
