Risk levelHigh

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

leontech is a small German IT solutions provider specializing in website development and search engine optimization services. The website presents basic information about the company’s offerings and provides clear contact details including phone, email, and physical address. The site uses a Bootstrap-based design with several JavaScript libraries, though some are outdated. There is no evidence of advanced security or privacy policies, and no HTTPS enforcement is visible in the provided content. The site lacks privacy and cookie policies, which impacts compliance and trust. Technically, the website employs common front-end technologies such as Bootstrap, jQuery, Font Awesome, and Google Fonts. However, the use of an outdated jQuery version (1.8.3) introduces potential security vulnerabilities. The site appears moderately optimized for performance and mobile devices but lacks advanced SEO and accessibility features. No analytics or tracking scripts were detected, indicating minimal user tracking. From a security perspective, the absence of HTTPS and security headers is a significant concern. The contact form includes client-side validation but no visible server-side security measures. No incident response or security policies are published. Overall, the security posture is weak, exposing the business to potential risks. The overall risk assessment suggests that while the business is legitimate and provides clear contact information, it should urgently improve its security and privacy practices to protect user data and enhance trust. Strategic recommendations include upgrading libraries, implementing HTTPS, publishing privacy and cookie policies, and adding security headers.

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

9 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  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

      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

  3. 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 X-Frame-Options header

      Prevents clickjacking attacks

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

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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.

Business context

Business profile

leontech operates as a small local IT service provider in Germany, focusing on web development and SEO. The business model is service-oriented, targeting small businesses or individuals needing website creation and optimization. The company uses a Bootstrap-based website template, indicating a cost-effective approach to web presence. There is no indication of partnerships, subsidiaries, or parent companies. The lack of certifications or trust signals suggests a nascent or small-scale operation. The company’s competitive advantage lies in localized service and direct contact availability. Growth indicators and revenue streams are not disclosed. The partnership ecosystem is minimal, limited to template providers. Strategic observations highlight the need for digital maturity improvements and enhanced security to compete effectively.

Security posture

The security maturity level of leontech’s website is low. Key vulnerabilities include the use of outdated JavaScript libraries, lack of HTTPS enforcement, and absence of security headers. No privacy or cookie policies are published, indicating compliance gaps with GDPR and related regulations. The contact form uses client-side validation but lacks visible server-side protections. Incident response readiness is not addressed. The security culture appears minimal, with no published security or incident response policies. These gaps expose the business to risks such as data interception, injection attacks, and reputational damage. Immediate remediation is recommended to improve data protection and regulatory compliance.

Recommendations

  1. Upgrade all JavaScript libraries, especially jQuery, to current supported versions to mitigate known vulnerabilities.
  2. Implement HTTPS with a valid SSL/TLS certificate and enforce HTTPS redirects site-wide.
  3. Publish comprehensive privacy and cookie policies to comply with GDPR and inform users about data handling.
  4. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  5. Conduct a security audit of the contact form and server-side processing to ensure input validation and prevent injection attacks.

Technical notes

Notes

The website uses a Bootstrap framework with several JavaScript libraries including jQuery 1.8.3, Font Awesome, Isotope, WOW.js, and Animate.css. Google Fonts are used for typography. The site is moderately optimized for mobile devices but lacks advanced accessibility features. Performance is average with no visible optimization for speed beyond standard Bootstrap responsiveness. The site does not use a CMS or advanced backend platform visible from the front-end code. Hosting provider details are not disclosed. The site uses a free BootstrapMade template, indicating potential technical debt and limited customization. There is no evidence of modern SEO practices or analytics integration. Technical risks include outdated libraries and lack of HTTPS.
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.
