Their business model includes tiered subscription tariffs with premium features such as push notifications, coupons, and monetization options. The company maintains a professional online presence with comprehensive contact information and GDPR-compliant privacy policies. Technically, the website employs modern JavaScript libraries and tracking tools such as Google Analytics, Google Tag Manager, and Facebook Pixel. The site is well-optimized for mobile devices and provides a user-friendly experience. However, no CMS or hosting provider details were identified. Performance is moderate with good SEO and basic accessibility features. From a security perspective, the site uses HTTPS and secure forms with GDPR consent. There is a lack of explicit security headers and no published security or incident response policies. No vulnerabilities or exposed sensitive data were detected.

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

5 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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

  2. 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 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';…
  3. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
  4. 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
      • 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

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

APPKEE operates in the competitive mobile app development sector, focusing on tailored solutions for a broad range of clients including public sector entities and private businesses. Their competitive advantage lies in the APP manager platform enabling easy app management without technical skills. Revenue streams include subscription tariffs, premium feature activation, and content monetization. The company maintains partnerships with regional offices in Prague, Brno, Bratislava, and Warsaw, and collaborates with OT Holding and Notifee for extended services. Growth indicators include a large portfolio of apps and active social media engagement. The business model emphasizes customer retention through push notifications and loyalty programs.

Security posture

The website demonstrates a moderate to good security posture with mandatory HTTPS and secure data collection forms including GDPR consent. However, the absence of security headers such as Content-Security-Policy and lack of published security or incident response policies indicate room for improvement. No direct vulnerabilities or exposed sensitive information were found in the HTML content. The use of multiple third-party tracking scripts necessitates regular security audits. Incident response readiness and vulnerability disclosure mechanisms are not evident, which could impact rapid mitigation of security incidents.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response page to improve transparency and preparedness.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Enhance website accessibility features to comply with standards and improve user inclusivity.
  5. Verify and update domain WHOIS information to improve domain trustworthiness and legitimacy.

Technical notes

Notes

The website uses a modern JavaScript-based tech stack with integration of Google Analytics, Google Tag Manager, Facebook Pixel, and YouTube iframe API for marketing and analytics. The site is mobile-optimized with responsive design and includes interactive elements such as video overlays and image galleries. No CMS was detected, suggesting a custom or static site architecture. Performance is moderate, with asynchronous loading of scripts to improve speed. The site lacks some advanced accessibility features and security headers, which are areas for technical enhancement. Hosting provider details are not disclosed, limiting infrastructure assessment.
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.
