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

Alternate GmbH operates the ALTERNATE B2B online shop, a professional e-commerce platform targeting businesses and government agencies in Germany. The company offers a broad range of electronics and technology products, supported by personal service and efficient logistics. The website emphasizes sustainability with CO2-neutral shipping and features a comprehensive product catalog with energy efficiency labels. The platform includes tools such as PC configurators and streamlined returns management, positioning it as a market leader in the B2B electronics retail sector. Technically, the website leverages Jakarta Faces (JSF) framework, Bootstrap 4, FontAwesome, and integrates Usercentrics for cookie consent management. Hosting and DNS are managed via Cloudflare, ensuring good performance and security. The site is mobile-optimized and includes SEO best practices, although accessibility features are basic. Analytics are implemented through Google Tag Manager, with moderate user tracking and good privacy compliance. Security posture is strong with HTTPS enforced, security headers present, and no visible vulnerabilities or exposed sensitive data. However, the site lacks a dedicated security policy or incident response contact information, and does not publish a security.txt file. Cookie consent and GDPR compliance are well managed. The domain WHOIS data is limited but consistent with the brand, and no WAF or blocking mechanisms interfere with content access. Overall, ALTERNATE B2B presents a trustworthy, professional, and secure platform for B2B electronics sales. Strategic improvements could include publishing detailed security policies and enhancing accessibility. The site’s sustainability focus and comprehensive product offerings strengthen its market position.

NIS2 Art. 21(2)

(a) Risk analysis and security policies: Not visible from outside
(b) Incident handling: One indicator
(c) Business continuity, backups and crisis management: Not visible from outside

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.

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.

Counted in this score

SSL/TLS: 75
Security headers: 55
Email security: 75
DNS health: 50
Network security: 0
GDPR outside view: 80
Average: 56
After the cap: 49

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

ALTERNATE GmbH is positioned as a leading B2B electronics retailer in Germany, serving businesses and government entities. Its competitive advantages include a vast product range, CO2-neutral shipping, and personalized customer service. The business model centers on online retail with value-added services like PC configuration and efficient returns. Revenue streams likely derive from product sales and partner programs. The company maintains a strong partnership ecosystem, including social media presence on LinkedIn and XING. Growth indicators include new product categories and sustainability initiatives. Operationally, the company leverages modern web technologies and third-party marketing tools to enhance customer engagement and conversion.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, presence of key security headers, and no visible exposure of sensitive data. Cookie consent is managed via Usercentrics, supporting GDPR compliance. However, the absence of a published security policy, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness. No critical vulnerabilities or malware indicators were detected. The use of Cloudflare for DNS and CDN adds a layer of protection. Overall, the security culture appears adequate but could benefit from formalized policies and incident response documentation.

Recommendations

Publish a dedicated security policy page outlining security practices and commitments.
Provide clear incident response contact channels such as security@ or abuse@ email addresses.
Implement and publish a security.txt file to facilitate vulnerability disclosures.
Enhance website accessibility to meet higher standards for users with disabilities.
Regularly review and audit third-party scripts and integrations for security risks.

Technical notes

Notes

The website is built on Jakarta Faces (JSF) framework with Bootstrap 4 for responsive design and FontAwesome for icons. It uses Usercentrics CMP for cookie consent and Google Tag Manager for analytics. Hosting is via Cloudflare, providing DNS and CDN services. Performance is moderate with good mobile optimization and SEO practices. Accessibility is basic, suggesting potential for improvement. The technical stack is modern and supports a professional e-commerce experience, though some legacy elements like JSF may require ongoing maintenance. The site uses asynchronous script loading and preloading for performance optimization.

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.
