B&B. Markenagentur GmbH is a medium-sized branding agency based in Hannover, Germany, specializing in strategic, creative, and communicative brand development. The company integrates human creativity with AI technologies to deliver innovative marketing and branding solutions, targeting businesses and public sector clients. Their service portfolio includes brand management, employer branding, change communication, and AI marketing, positioning them as a forward-thinking agency in the branding industry. Technically, the website demonstrates a modern and performant infrastructure with responsive design, multimedia integration (YouTube, Vimeo videos), and advanced cookie consent mechanisms. The use of Google Tag Manager with a custom domain, A/B testing tools, and lazy loading images reflects a mature digital presence. Hosting is likely provided by kasserver.com, consistent with the domain's nameservers. From a security perspective, the site enforces HTTPS, employs cookie consent compliant with GDPR, and uses CSRF tokens for form protection. However, explicit security headers are not detected, and no public security or incident response policies are found. No vulnerabilities or exposed sensitive data are evident in the content, indicating a solid security posture. Overall, the website is professional, trustworthy, and compliant with privacy regulations, with a high-quality user experience and clear business information.

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

5 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

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 · found on this site
  • 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

B&B. Markenagentur GmbH operates in the branding and marketing sector with a focus on integrating AI and data-driven insights. Their competitive advantage lies in combining human intuition with AI capabilities, offering services that span strategy, design, digital transformation, and content activation. The company targets corporate clients and public sector organizations primarily in Germany, leveraging a strong partnership ecosystem including ueberwegs.de. Their business model revolves around consultancy, creative services, and digital marketing solutions, supported by a professional online presence and active social media engagement. Growth indicators include recent projects with notable clients and a visible recruitment drive, signaling expansion and talent acquisition.

Security posture

The website exhibits a mature security posture with mandatory HTTPS, GDPR-compliant cookie consent, and CSRF protection on forms. The absence of explicit security headers such as CSP or HSTS is a minor gap. No incident response or security policy pages are published, which could limit transparency in case of security events. Third-party scripts are used responsibly, but continuous monitoring is advised. Overall, the site minimizes exposure to common web vulnerabilities and respects user privacy, aligning with best practices for a marketing agency.

Recommendations

  1. Implement and enforce security headers including Content Security Policy (CSP), HSTS, X-Content-Type-Options, and X-Frame-Options.
  2. Publish a dedicated security policy and incident response plan accessible to users and partners.
  3. Introduce a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance form security with CAPTCHA or bot detection to prevent automated abuse.

It uses lazy loading for images and videos to optimize performance. The integration of Google Tag Manager with a custom domain and A/B testing tools indicates advanced marketing technology adoption. Hosting is managed via kasserver.com, consistent with domain registration data. The site loads quickly and is optimized for mobile devices, with good accessibility 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.
