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

2 findings rated critical or high. Fix these first.

  1. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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

plenigo holds a strong position in the media subscription management market, leveraging its association with Billwerk+ and the new Frisbii brand to enhance its offerings. The business model centers on SaaS subscription software tailored for publishers and media companies, enabling them to monetize digital and print content effectively. The extensive list of customer logos and case studies reflects a broad and diverse client base, indicating market acceptance and trust. The company provides comprehensive developer support and integration options, facilitating adoption and customization. Growth is supported by multilingual capabilities and a pan-European focus. Strategic partnerships and rebranding efforts suggest an ambition to scale and innovate within the subscription economy for media.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is properly implemented, and the domain is protected with clientTransferProhibited status, reducing risk of unauthorized domain transfers. However, the absence of DNSSEC and security headers such as Content Security Policy, HSTS, and X-Frame-Options indicates room for improvement in defense-in-depth. No incident response or vulnerability disclosure information is publicly available, which could hinder rapid mitigation of security issues. Privacy policies and cookie consent mechanisms are not evident, potentially exposing compliance gaps under GDPR and related regulations. The use of Plausible Analytics suggests a privacy-conscious approach to user tracking. Overall, the security posture is functional but would benefit from enhanced policies, headers, and transparency.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to ensure GDPR compliance.
  2. Enable DNSSEC on the domain to protect against DNS spoofing and improve domain security.
  3. Add standard security headers (CSP, HSTS, X-Frame-Options, X-Content-Type-Options) to harden the website against common web attacks.
  4. Publish a security policy and incident response contact information, including a security.txt file, to improve transparency and readiness.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerable components are in use and maintain secure coding practices.

Technical notes

Notes

The website is built on WordPress CMS with multilingual support via WPML, indicating a mature and flexible content management approach. It uses jQuery and Lottie for animations, enhancing user experience. Plausible Analytics is integrated for lightweight, privacy-friendly analytics. The site is moderately performant with responsive design and good SEO metadata including Open Graph and JSON-LD structured data. Hosting details are limited, but domain registration is stable and long-term. The technical stack is modern but could benefit from improved security configurations and performance optimizations. The extensive use of customer logos and references is well implemented with lazy loading and accessibility considerations. Overall, the technical infrastructure supports the business goals effectively with opportunities for security and performance enhancements.
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.
