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

ALTER s.r.o. is a Czech Republic-based company specializing in the wholesale and manufacturing of cleaning, disinfecting, and hygiene products. With over 24 years of market presence, the company serves primarily registered business customers, offering a broad range of products including cleaning agents, packaging materials, and gastro supplies. The website reflects a well-established regional wholesaler with a clear B2B business model and a focus on professional clientele. Technically, the website employs standard web technologies including HTML, CSS, JavaScript, and jQuery, but uses an outdated jQuery version which poses security risks. The site is moderately optimized for performance and mobile use, with basic accessibility and good SEO practices. Security posture is moderate; HTTPS is used, and cookie consent mechanisms are implemented, but there is a lack of modern security headers and the use of outdated libraries. WHOIS data is unavailable, which slightly reduces trustworthiness, but the website content and contact information support legitimacy. Overall, the site is functional and professional but would benefit from technical and security updates.

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

8 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. 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

  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 Strict-Transport-Security header

      Forces HTTPS connections

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

    • High

      Missing Content-Security-Policy header

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

The company operates in the retail and manufacturing sectors, focusing on cleaning and hygiene products for business customers in the Czech Republic. Its competitive advantage lies in its long-standing market presence and in-house production of cleaning and cosmetic products. The business model is B2B wholesale combined with manufacturing, targeting registered companies with IČO numbers. Revenue streams likely come from product sales and distribution. The website indicates a stable operation with clear contact channels and product listings. There is no evidence of extensive partnerships or subsidiaries. The company maintains a professional online presence with consistent branding and relevant content for its target audience.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is enforced, and cookie consent is implemented, indicating awareness of privacy regulations. However, the use of an outdated jQuery version (1.7.2) introduces potential vulnerabilities. No advanced security headers such as Content-Security-Policy or X-Frame-Options were detected, and there is no visible incident response or security policy information. The absence of WHOIS data reduces transparency. Overall, while basic security measures are in place, improvements are needed to address known vulnerabilities and enhance compliance with modern security standards.

Recommendations

  1. Update all JavaScript libraries, especially jQuery, to the latest secure versions to mitigate known vulnerabilities.
  2. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to strengthen defense against common web attacks.
  3. Conduct an SSL/TLS configuration audit to ensure strong encryption and eliminate potential weaknesses.
  4. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  5. Enhance mobile optimization and accessibility to improve user experience and compliance with standards.

Technical notes

Notes

The website uses a traditional web stack with HTML, CSS, and JavaScript, including jQuery 1.7.2 and Lightbox scripts. The site is moderately optimized for performance and mobile devices but lacks modern frameworks or CMS indications. SEO is handled well with proper meta tags and structured navigation. The absence of modern JavaScript frameworks or CMS platforms suggests a custom or legacy implementation. Technical debt is evident in outdated libraries and missing security headers. Hosting provider details are not discernible from the provided data. Opportunities exist to modernize the tech stack, improve security configurations, and enhance mobile responsiveness.
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.
