Security score

41/100

Risk levelHigh

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

Zander & Ingeström is a well-established Swedish company specializing in flow and heat technology products and services, including industrial pumps, electric boilers, and water products. The company is positioned as a leading player in its sector and operates under the parent company Christian Berner. The website reflects a mature digital presence with clear navigation, multilingual support, and detailed product and supplier listings. Technically, the site uses modern web technologies including Episerver CMS, Google Analytics, Microsoft Application Insights, and Cookiebot for privacy compliance. Security posture is strong with HTTPS enforcement and appropriate security headers. Privacy compliance is well addressed with a comprehensive cookie consent mechanism and a linked privacy policy. However, explicit terms of service and direct contact information are not present on the site, which could be improved for transparency and user trust.

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

17 findings rated critical or high. Fix these first.

GDPR outside view
These are the privacy signals visitors and data protection authorities look for under GDPR.
- Critical
  No HTTPS encryption
  GDPR requires appropriate security measures for personal data
  What to do: Implement SSL/TLS certificate for HTTPS
  References

  - OWASP A04:2025

  - GDPR Art. 32(1)(a)
  - NIST SC-8: NIST SP 800-53 Rev. 5 SC-8: Transmission Confidentiality and Integrity
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.
- Critical
  No HTTPS Encryption
  Website does not use HTTPS encryption, making all data transmission vulnerable to interception
  What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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: 0
Security headers: 30
Email security: 85
DNS health: 70
Network security: 0
GDPR outside view: 58
Average: 41

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

The company targets industrial customers requiring specialized flow and heat technology solutions. Its business model is B2B, focusing on supplying industrial equipment and services. The website demonstrates a broad partnership ecosystem with multiple supplier brands and partner companies referenced. The presence of detailed product categories and supplier listings indicates a comprehensive catalog approach. The company benefits from being part of the Christian Berner group, enhancing its market credibility. Growth indicators include active content updates, product diversification, and integration of modern analytics and marketing tools.

Security posture

The website exhibits a strong security posture with HTTPS enabled and multiple security headers implemented. The use of Cookiebot ensures GDPR-compliant cookie consent management. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in security transparency and readiness. The integration of Microsoft Application Insights provides telemetry and monitoring capabilities, enhancing operational security awareness.

Recommendations

Publish explicit terms of service and security policies on the website to enhance transparency.
Add clear contact information including security incident contacts (e.g., security@ or abuse@ emails).
Implement a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.
Enhance user trust by providing more visible business credentials and certifications if applicable.

Technical notes

Notes

The website is built on the Episerver CMS platform, leveraging modern web technologies such as Bootstrap for responsive design and jQuery for interactivity. It integrates Google Analytics and Microsoft Application Insights for analytics and telemetry, and Cookiebot for cookie consent management. The site is hosted likely on Microsoft Azure, inferred from cookie names and privacy links. Performance is moderate with good mobile optimization and accessibility features. SEO is supported by proper meta tags and structured navigation. Technical risks are low, but continuous monitoring and updates are recommended to maintain security and performance.

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.
