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

Opus Marketing GmbH is a medium-sized German branding agency specializing in strategic branding, digital transformation, and sustainable brand development. The company targets businesses seeking to build impactful and future-oriented brands. Their website reflects a professional and consistent brand image with excellent content quality and clear navigation. Technically, the site is built on WordPress with modern marketing and analytics tools integrated, including GDPR-compliant cookie consent via Usercentrics. However, the absence of a valid SSL certificate and HTTPS configuration is a critical security weakness, exposing visitors to potential risks. The DNS setup lacks advanced security features such as DNSSEC and domain protection locks, which should be addressed to enhance domain security. Overall, the business credibility and privacy compliance are strong, but the security posture requires urgent improvement.

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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  2. 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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

  4. 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';…

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 branding and marketing sector with a clear focus on strategic and sustainable branding services. Their market position is solid within the German market, supported by a professional online presence and active social media channels. The business model is service-oriented, targeting corporate clients who value brand impact and digital presence. The use of advanced marketing tools and GDPR-compliant mechanisms indicates a mature digital strategy. No parent or subsidiary companies were identified, suggesting an independent operation. The company has been active since at least 2015, with domain registration dating from 2020, consistent with their business timeline.

Security posture

The website demonstrates basic security best practices through HTTP security headers and GDPR-compliant cookie consent. However, the lack of a valid SSL certificate and HTTPS support is a major vulnerability that undermines user trust and data protection. The absence of DNSSEC and domain protection locks further exposes the domain to potential DNS attacks or unauthorized changes. No explicit security or incident response policies are published on the site. The current security posture is low and requires immediate remediation to meet modern security standards and compliance requirements.

Recommendations

  1. Obtain and properly configure a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 or TLS 1.3) and configure OCSP stapling and session resumption for improved security and performance.
  3. Implement DNSSEC and domain protection locks to secure DNS integrity and prevent unauthorized domain modifications.
  4. Publish a clear security policy and incident response contact information to enhance transparency and preparedness.
  5. Continue maintaining GDPR compliance and enhance accessibility features to improve user experience and legal adherence.

Technical notes

Notes

The website is built on WordPress using WPBakery Page Builder and Yoast SEO, indicating a modern CMS with SEO optimization. It integrates Usercentrics for cookie consent and uses Google Tag Manager and Facebook Pixel for analytics and marketing. The hosting appears to be provided by a German hosting provider associated with agenturserver.de. Performance is moderate with some lazy loading and preconnect optimizations. Mobile optimization is good, but accessibility features are basic. The lack of HTTPS is a significant technical debt and security risk. Overall, the technical infrastructure supports a professional digital presence but requires urgent security upgrades.
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.
