Partial score · DNS & email only

30/100

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

LineMetrics GmbH is a medium-sized Austrian company specializing in smart building solutions through integrated sensor systems based on LoRaWAN technology. Their platform enables real-time data collection and analysis for energy consumption, room climate monitoring, and operational efficiency improvements. The company has a strong market presence with over 400 clients and 15,000 sensors deployed, positioning itself as a reliable provider in the real estate and technology sectors. Technically, the website is built on WordPress with modern plugins and integrations such as Kadence Blocks, WP Rocket, Google Tag Manager, and Zoho CRM, reflecting a mature digital infrastructure. However, a critical security gap exists due to the absence of a valid SSL certificate and lack of HTTPS, which significantly impacts the security posture. Privacy compliance is well addressed with comprehensive policies and active consent mechanisms. Overall, while the business and content quality are excellent, urgent improvements in security configurations are recommended to enhance trust and protect user data.

NIS2 and GDPR posture

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

2 findings rated critical or high. Fix these first.

  1. 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

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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

LineMetrics operates in the intersection of real estate and technology, offering a comprehensive all-in-one system including hardware (sensors, gateways) and cloud software for data visualization and management. Their business model focuses on B2B SaaS and hardware sales, targeting facility and asset managers seeking efficient, scalable, and wireless monitoring solutions. The company leverages partnerships with Zoho for CRM and recruitment, and maintains active social media presence on LinkedIn, Facebook, and Instagram. Their offerings cover over 50 use cases, emphasizing flexibility and ease of deployment. The company’s growth is supported by a professional website with clear navigation, detailed product information, and multiple contact channels, indicating a well-established market position.

Security posture

The website’s security posture is currently weak due to the lack of a valid SSL certificate and absence of HTTPS, which is a critical vulnerability that exposes users to potential data interception and undermines trust. Although some security headers like HSTS are present, they are ineffective without HTTPS. No advanced security frameworks or incident response policies are found on the site. The use of Google reCAPTCHA and consent-based cookie management indicates some attention to security and privacy. The absence of DNSSEC and CAA records further reduces domain security. Immediate remediation is required to install and maintain valid SSL/TLS certificates, enable modern TLS protocols, and implement comprehensive security policies to protect data and comply with regulations.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the entire website.
  2. Enable modern TLS protocols (TLS 1.2 or 1.3) and disable all insecure protocols to improve encryption.
  3. Implement DNSSEC and CAA records to enhance domain security and prevent certificate mis-issuance.
  4. Publish a security policy and incident response contact information to improve transparency and readiness.
  5. Regularly audit and update all third-party libraries and plugins to avoid vulnerabilities.

Technical notes

Notes

The website is built on WordPress using the Kadence theme and Kadence Blocks plugin, enhanced with WP Rocket for performance optimization. It integrates Google Tag Manager for analytics and Zoho CRM for lead management, including a detailed contact form with reCAPTCHA for spam protection. Despite these modern technologies, the site suffers from poor SSL configuration, lacking a valid certificate and HTTPS support, which is a major technical risk. Performance metrics are not available, but the use of lazy loading and caching plugins suggests moderate to good performance. The site is mobile-optimized and accessible, with good SEO practices including meta tags and structured data. Technical improvements should focus on security hardening and performance monitoring.
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.
