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

Resonanz Digital is a well-established digital agency based in Austria, specializing in WordPress websites, online shops, eCommerce solutions, SEO, and Google Ads optimization. With over 20 years of experience and a Google Partner certification, the company targets small and medium-sized enterprises, founders, and individual entrepreneurs primarily in the German-speaking market. Their service portfolio includes web design, development, online marketing, and ongoing maintenance, positioning them as a trusted partner for digital presence creation. Technically, the website is built on WordPress using the Avia Framework and integrates various modern web technologies including jQuery and WP Rocket for performance optimization. The hosting infrastructure appears to be on Google Cloud, providing a reliable platform. The site supports multilingual content via WPML and employs structured data for SEO enhancement. Performance is moderate with room for improvement in load times. From a security perspective, the site has correctly configured SPF and DMARC DNS records, indicating good email authentication practices. However, the lack of a valid SSL certificate and absence of TLS protocols represent significant security weaknesses, exposing users to potential data interception risks. The cookie consent mechanism is implemented, supporting GDPR compliance, but the DMARC policy is set to 'none', which could be strengthened. Overall, Resonanz Digital demonstrates a mature digital presence with strong business credibility and customer trust signals. The main risk lies in the missing HTTPS security layer, which should be addressed promptly to protect user data and enhance trust. Strategic improvements in security posture and performance optimization will further solidify their market position.

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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

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.

Business context

Business profile

Resonanz Digital operates as a specialized digital agency focusing on WordPress and eCommerce solutions for SMEs and individual entrepreneurs in Austria. Their competitive advantage lies in their long-standing market presence, Google Partner status, and comprehensive service offerings from web design to online marketing. Revenue streams likely include project-based web development, ongoing maintenance contracts, and digital marketing services. The company targets German-speaking clients seeking tailored digital solutions with a focus on usability and marketing effectiveness. Their partnership with LWND and membership in WP Network Austria indicate a collaborative ecosystem enhancing service quality. Growth indicators include active client projects showcased and a strong online reputation via ProvenExpert. The agency maintains a professional brand image with consistent messaging and high-quality content, supporting sustained client trust and market relevance.

Security posture

The current security maturity of Resonanz Digital's website is moderate but with critical gaps. The presence of SPF and DMARC records shows awareness of email security best practices, although the DMARC policy is permissive ('none'), which limits its effectiveness against spoofing. The absence of DNSSEC and CAA records indicates opportunities to strengthen DNS security. The most significant vulnerability is the lack of a valid SSL certificate and disabled TLS protocols, resulting in unencrypted HTTP traffic that exposes users to interception and man-in-the-middle attacks. No advanced security headers or mechanisms like HSTS or OCSP stapling are implemented. Incident response and security policy information are not publicly available, suggesting limited transparency in security governance. The cookie consent implementation aligns with GDPR requirements, reflecting compliance culture. Overall, the security posture requires urgent enhancement in transport security and policy enforcement to mitigate risks and comply with evolving regulations.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable and enforce modern TLS protocols (TLS 1.2 and TLS 1.3) and disable legacy protocols.
  3. Configure HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  4. Strengthen DMARC policy from 'none' to 'quarantine' or 'reject' to reduce email spoofing risks.
  5. Implement DNSSEC and CAA records to enhance DNS security and certificate issuance control.
  6. Publish a clear security policy and incident response contact information to improve transparency.
  7. Optimize website performance to reduce load times and improve user experience.
  8. Maintain and regularly update cookie consent mechanisms to ensure ongoing privacy compliance.

Notes

The website is built on WordPress CMS with the Avia Framework and uses jQuery and WP Rocket for frontend enhancements and performance optimization. Hosting is provided via Google Cloud infrastructure, as indicated by the IP address. The site supports multilingual content through WPML plugin. Structured data in JSON-LD format is implemented for organization, website, and article schema, improving SEO. The site loads moderately fast with a page size of approximately 29KB and 58 resources. However, the absence of HTTPS and modern TLS protocols is a critical technical debt. The use of external scripts for ProvenExpert reviews and Google services is noted. Lazy loading and prefetching techniques are employed to enhance performance. Overall, the technical infrastructure is modern but requires urgent security upgrades and performance tuning to reduce risks and improve operational resilience.
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.
