Risk levelHigh

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

Symphony Digital is a Czech-based small digital agency specializing in creating professional websites and e-commerce solutions, complemented by internet marketing services such as SEO, SEM, and social media marketing. The company targets businesses and individuals seeking to establish or improve their online presence. Their portfolio includes various local Czech clients, indicating a focused regional market position. Technically, the website is built on WordPress with modern integrations like Google Analytics, Tag Manager, and reCAPTCHA, reflecting a moderate level of digital maturity. Security posture is adequate with HTTPS and anti-bot measures but lacks some advanced security headers and published policies. Overall, the website is professional and trustworthy but would benefit from enhanced privacy compliance and security documentation.

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

10 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: PostgreSQL

      Port 5432 (PostgreSQL) is publicly accessible - PostgreSQL - Database server

      What to do: Immediately restrict access to PostgreSQL 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"

      • 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"

    • 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 · 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 as a service provider in the technology sector, focusing on web development and digital marketing. Their business model revolves around delivering tailored web and e-shop solutions with ongoing marketing support. The presence of a partner domain (symphony-studio.cz) suggests a collaborative ecosystem. The company appears to have steady growth potential within the Czech market, leveraging local language content and regional SEO. Revenue streams likely include project-based web development and recurring marketing services. The target customer segment is primarily small to medium-sized enterprises and individual entrepreneurs in the Czech Republic.

Security posture

The website demonstrates a baseline security maturity with HTTPS enforced and Google reCAPTCHA protecting forms. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No incident response or security policy information is published, which may hinder transparency and trust. There is no evidence of vulnerability disclosure mechanisms or a designated data protection officer. The site does not expose sensitive data or use vulnerable libraries visibly, but regular updates and security hardening are recommended to maintain resilience.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  2. Implement security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Add an incident response contact or security email to facilitate vulnerability reporting and improve transparency.
  4. Regularly update WordPress core and plugins to mitigate risks from known vulnerabilities.
  5. Consider creating a security.txt file to formalize vulnerability disclosure and improve security culture.

Technical notes

Notes

The website is built on WordPress 5.7.2 with Visual Composer as the page builder, indicating a common and well-supported CMS platform. It uses Google Fonts loaded asynchronously, Google Analytics and Tag Manager for tracking, and Google reCAPTCHA v3 for bot protection. Hosting is inferred to be with VAS Hosting based on nameservers. Performance is moderate with some asynchronous script loading and lazy loading of images. Mobile optimization is good, and SEO practices are evident through meta tags and structured Open Graph data. Accessibility is basic but could be improved. Overall, the technical stack is standard for small digital agencies but could benefit from modernization and enhanced security configurations.
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.
