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

MVB GmbH operates as an official ISNI agency, providing services that enable clear and unique identification of authors and creators to enhance product visibility in the book trade. The company targets publishers, authors, and book trade professionals primarily in Germany, offering ISNI search and registration services alongside metadata management. The website reflects a professional and consistent brand presence with clear navigation and relevant content focused on bibliographic identifiers. Technically, the website employs modern web technologies including Bootstrap, FontAwesome, Google Tag Manager, and a cookie consent management system. Hosting is provided by Anexia, indicated by the nameservers. The site is mobile optimized and performs moderately well, with good SEO and accessibility basics. Security practices include HTTPS enforcement and cookie consent, though some security headers and explicit security policies are absent. The security posture is solid with no visible vulnerabilities or exposed sensitive data. However, the absence of a published security policy, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. Privacy compliance is strong with clear privacy and cookie policies and GDPR adherence. Contact information is clearly provided, enhancing business credibility. Overall, the website and business demonstrate a high level of professionalism and trustworthiness with a low risk profile. Strategic improvements in security policy publication and vulnerability disclosure would further strengthen the security posture and stakeholder confidence.

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.

    • 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

    • 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. 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 X-Frame-Options header

      Prevents clickjacking attacks

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

      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

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

MVB GmbH holds a strong market position as the official ISNI agency in Germany, serving the media and publishing sector. Their business model revolves around providing authoritative identification services for authors and organizations, which is critical for metadata accuracy in the book trade. The company leverages partnerships with ISNI International Agency and integrates with VLB publisher services, enhancing its ecosystem. Revenue streams likely include registration fees and metadata services. The target customer segments are publishers, authors, and book retailers seeking reliable author identification. Growth indicators include active content updates and integration with multiple related products. The partnership ecosystem includes ISNI-IA and VLB, reflecting strategic alignment with industry standards.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and cookie consent mechanisms in place. No critical vulnerabilities or exposed sensitive data were detected. However, the lack of security headers such as Content-Security-Policy and absence of a published security policy or incident response contacts indicate gaps in security transparency and preparedness. There is no evidence of a vulnerability disclosure program or security.txt file, which could hinder responsible vulnerability reporting. Compliance with GDPR is evident through privacy and cookie policies. Overall, the security culture appears professional but could benefit from enhanced documentation and proactive disclosure practices.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Establish and publicize an incident response contact channel, such as security@ or abuse@ email addresses.
  4. Create and host a security.txt file to facilitate vulnerability disclosure and improve transparency.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website is built using modern front-end technologies including Bootstrap for responsive design, FontAwesome for icons, and Owl Carousel for interactive elements. Google Tag Manager is used for analytics and tracking, integrated with a cookie consent management system (CookieFirst) to comply with privacy regulations. Hosting is managed by Anexia, a professional hosting provider, as indicated by the nameservers. The site loads asynchronously and defers scripts to optimize performance. Mobile optimization is good, and SEO meta tags including Open Graph and Twitter Cards are properly implemented. Accessibility features are basic but present. There is no detected CMS, suggesting a custom or static site build. Performance is moderate, with opportunities for further optimization in script loading and caching.
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.
