Risk levelHigh

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

UAB Kalvis is a medium-sized Lithuanian company specializing in metal processing and manufacturing of domestic and industrial boilers. The company offers a range of heating equipment and subcontracting services, targeting residential, commercial, and industrial customers. Their market position is strong within Lithuania with export activities to multiple countries. The website reflects a professional business with clear service offerings and contact information. Technically, the site is built on WordPress with WooCommerce and uses modern frameworks like Bootstrap and jQuery, providing a good user experience and mobile optimization. Security measures include HTTPS and Google reCAPTCHA on forms, but lack of security headers and privacy policies indicate room for improvement. The absence of WHOIS data reduces domain trustworthiness, but the website content and business information appear legitimate. Overall, the site is functional and professional but would benefit from enhanced privacy compliance and security hardening.

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

11 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

  2. 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

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

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 · 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

Kalvis operates in the energy and manufacturing sectors, focusing on heating solutions and metal processing. Their business model combines product manufacturing with subcontracting and service offerings such as consulting and installation. The company targets a broad audience including residential users and industrial clients. The presence of a customer login zone suggests ongoing client relationships and possibly repeat business. Their digital presence includes social media channels and a professional website, supporting brand visibility and customer engagement. The lack of detailed financial or founding data limits deeper business intelligence insights. No related or subsidiary domains were identified, and partnerships appear limited to IT service providers.

Security posture

The website demonstrates a moderate security posture with HTTPS enforced and use of Google reCAPTCHA to protect forms from automated abuse. However, the absence of key security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces defense-in-depth. No explicit security policies, incident response contacts, or vulnerability disclosure mechanisms are present, which could hinder incident management and transparency. The WHOIS data failure raises concerns about domain registration legitimacy, though the website content does not indicate malicious intent. Overall, security practices are adequate but could be significantly improved to meet higher compliance and trust standards.

Recommendations

  1. Implement comprehensive privacy and cookie policies with explicit user consent mechanisms to improve GDPR compliance.
  2. Add security headers including Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options to strengthen site security.
  3. Publish a security policy and incident response contact information to enhance transparency and preparedness.
  4. Regularly audit and update all plugins, themes, and WordPress core to mitigate vulnerabilities.
  5. Investigate and resolve WHOIS data issues to improve domain registration trust and legitimacy.

Technical notes

Notes

The website is built on a WordPress CMS platform with WooCommerce for e-commerce capabilities. It uses Bootstrap for responsive design and jQuery for client-side scripting. Google reCAPTCHA is integrated for bot protection on forms. The site loads multiple CSS and JS assets including plugins for product filtering and social sharing (AddToAny). Performance is moderate with no evident blocking or WAF interference. Mobile optimization is good, but accessibility features are basic. SEO is supported by meta tags and Open Graph data. Hosting provider details are not discernible from the content. The site would benefit from improved security headers and privacy compliance features.
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.
