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

PEWO is a German company specializing in compact and modular plant technology for the transfer and distribution of building heat, combined with comprehensive network knowledge and service offerings. The website presents a professional and focused business presence targeting B2B customers in the energy and building technology sector. Technically, the site is built using modern frameworks such as Gatsby and Bootstrap, offering a responsive and well-structured user experience. However, the absence of WHOIS domain registration data raises concerns about the domain's legitimacy and registration status. Security posture is moderate with no visible advanced security headers or policies, and privacy compliance is minimal due to the lack of privacy and cookie policies. Overall, the site is functional and professional but requires improvements in transparency, security, and compliance to enhance trust and credibility.

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.

  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.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

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 operates in the energy sector, focusing on modular systems for building heat distribution. Its business model revolves around providing technical plant solutions and related services. The website content is tailored to industry professionals and decision-makers in building technology. While the site demonstrates consistent branding and good content quality, the lack of publicly available company registration and contact information limits the ability to fully assess business credibility. There is no evidence of partnerships or subsidiaries from the provided data. The company appears to maintain a medium-sized operation with a specialized market niche.

Security posture

The security maturity level of the website is moderate. HTTPS is implied but not explicitly confirmed in the data. No security headers such as Content-Security-Policy or X-Frame-Options were detected. There are no visible vulnerabilities or exposed sensitive data in the provided content. The absence of privacy and cookie policies indicates compliance gaps with GDPR and other data protection regulations. Incident response readiness and security culture indicators are not evident. The site would benefit from implementing standard security best practices and transparency measures to improve its security posture.

Recommendations

  1. Implement and enforce HTTPS with strong SSL/TLS configuration.
  2. Add comprehensive privacy and cookie policies to comply with GDPR and enhance user trust.
  3. Deploy security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Publish clear contact information including security and incident response contacts.
  5. Conduct regular security audits and vulnerability assessments to maintain a robust security posture.

  4. No contact emails, phone numbers, or social media links explicitly found in the provided HTML snippet.
  5. Website uses modern frontend technologies (Gatsby, Bootstrap).

  7. No visible security headers or advanced security configurations detected in the provided data.
  8. No analytics or tracking scripts detected in the provided HTML snippet.
Technical notes

Notes

The website uses a modern static site generator (Gatsby) combined with Bootstrap 5 for styling, indicating a contemporary and maintainable technical infrastructure. The site is likely hosted on a platform supporting static sites, though the hosting provider is not identified. Performance is moderate with good mobile optimization and basic accessibility features. SEO optimization is basic with meta tags present but no advanced structured data or Open Graph tags detected. There is no evidence of analytics or tracking scripts, which may reflect a privacy-conscious approach or incomplete data capture. Technical risks include the lack of visible security headers and missing domain registration data, which could impact business operations and trust.
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.
