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

Plugo s.r.o. is a Czech-based digital marketing agency specializing in PPC campaigns, SEO, custom e-shop and website development, and content creation. With over 15 years of experience, they serve clients primarily in the Czech Republic and Austria, focusing on delivering tailored digital solutions that enhance online visibility and business growth. The website reflects a professional and consistent brand image with clear service offerings and client references. Technically, the site employs modern web technologies including Google Tag Manager, GSAP, and cookie consent mechanisms, ensuring a good user experience and moderate performance. Security posture is adequate with HTTPS and cookie consent, but lacks explicit security headers and published privacy policies, which are areas for improvement. The absence of WHOIS data limits domain trust assessment, but the presence of detailed contact and company registration information supports business credibility. Overall, the site is safe, professional, and well-structured, though it would benefit from enhanced privacy compliance and security best practices.

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

12 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

    • 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

    • 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

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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Plugo operates as a small-sized, essential entity in the technology sector, offering integrated digital marketing and web development services. Their market positioning is solid within the Czech and Austrian markets, leveraging a service-based business model focused on PPC, SEO, and custom e-commerce solutions. The company demonstrates growth potential through active recruitment and a portfolio of client references. Their ecosystem includes partnerships with major ad networks and tracking services, supporting a comprehensive marketing approach. Strategic observations highlight the need for formalized privacy and security policies to align with regulatory standards and enhance client trust.

Security posture

The website shows a moderate security maturity level with HTTPS enabled and cookie consent implemented, indicating awareness of privacy and security concerns. However, the lack of visible security headers such as Content Security Policy, HSTS, and X-Frame-Options suggests room for improvement in defense-in-depth strategies. No vulnerabilities or exposed sensitive data were detected in the content analysis. Compliance gaps exist due to missing privacy and terms of service documentation, which are critical for GDPR adherence. Incident response readiness and security culture indicators are not evident from the site. Overall, the security posture is functional but could be strengthened by adopting industry best practices and transparency measures.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  2. Add security headers including Content Security Policy, HSTS, and X-Frame-Options to enhance site security.
  3. Establish and publicize a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Conduct regular audits of third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Enhance accessibility features to improve user experience for all visitors and comply with standards.

Technical notes

Notes

The website utilizes a modern technology stack including Google Tag Manager for analytics and marketing, GSAP for animations, and Google Fonts for typography. The presence of a cookie consent banner indicates attention to privacy regulations. The site is responsive and optimized for mobile devices, with good navigation and content structure. Performance appears moderate, with asynchronous loading of scripts. No CMS or hosting provider details were detected. Technical debt is minimal based on the provided content, but the absence of security headers and privacy documentation suggests areas for modernization. Overall, the technical infrastructure supports the business goals effectively but should incorporate enhanced security and 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.
