Risk levelMedium

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

PlentyONE GmbH operates a leading cloud-native all-in-one e-commerce ERP platform that connects brands, manufacturers, and retailers to over 150 marketplaces globally. The company positions itself as a scalable and flexible solution provider with a strong partner ecosystem and expert consulting services. Technically, the website is built on HubSpot CMS, hosted on AWS infrastructure, and employs modern web technologies including TLS 1.3 for secure communications. However, some security best practices such as HSTS, DMARC, and OCSP stapling are not implemented, which could be improved to enhance security posture. The site uses Cookiebot for GDPR-compliant cookie consent management and integrates Google Analytics and Facebook Pixel for marketing and analytics purposes. Overall, the platform demonstrates a mature digital presence with enterprise-level business scale and strong market positioning.

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

3 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

PlentyONE targets medium to large enterprises in the e-commerce sector, offering a SaaS platform combined with strategic consulting and operational support. The company supports diverse industries including fashion, electronics, and consumer goods, and emphasizes international marketplace connectivity. With over 55,000 users and processing 116 million orders annually, PlentyONE has a significant market footprint. The business model includes subscription-based software services and value-added growth services. Partnerships with Amazon Ads and other marketplace partners strengthen its competitive advantage. The company is headquartered in Germany and maintains a consistent and professional brand image across its digital assets.

Security posture

The website's security posture is moderate with use of modern TLS protocols and valid SSL certificates. SPF records are configured to protect email sending domains, but the absence of DMARC and DNSSEC reduces email and DNS security. The lack of HSTS and OCSP stapling indicates potential vulnerabilities to downgrade attacks and slower certificate revocation checks. No explicit security or incident response policies are published on the site, and no dedicated security contact emails are provided. The presence of GoBD certification indicates compliance with German accounting and data security standards. Overall, the security maturity is adequate for business operations but could benefit from enhancements in email authentication and transport security.

Recommendations

  1. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload to enforce HTTPS and prevent downgrade attacks.
  2. Implement a DMARC policy to improve email authentication and reduce phishing risks.
  3. Define and correct CAA DNS records to restrict certificate authorities authorized to issue certificates for the domain.
  4. Enable OCSP stapling on the web server to improve SSL certificate revocation checking performance and security.
  5. Publish a clear security policy and incident response contact information to enhance transparency and trust.
Technical notes

Notes

The website is built on HubSpot CMS, leveraging AWS for hosting and DNS services. It uses modern JavaScript libraries including jQuery 3.7.1 and integrates multiple marketing and analytics tools such as Google Analytics 4, Google Tag Manager, and Facebook Pixel. The SSL configuration supports TLS 1.3 and TLS 1.2 but lacks HSTS and OCSP stapling. DNS records include multiple A records and MX records pointing to Google mail servers, with SPF configured but no DMARC or DNSSEC. The site performance is slow with a load time of over 20 seconds and a large page size (~2.3MB), indicating potential optimization opportunities. Mobile optimization and accessibility are good, with consistent branding and professional design. Technical risks include missing security headers and potential DNS security gaps.
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.
