Cero Generation is a prominent European solar energy developer specializing in utility scale solar and battery storage projects. With a substantial portfolio of 25GW under evaluation and active operations across eight European countries, the company is positioned as a leader in the renewable energy sector. The business operates as a portfolio company under Macquarie Asset Management, emphasizing a commitment to delivering clean, reliable, and cost-effective renewable energy solutions. The website reflects a professional and consistent brand image, targeting stakeholders in the European energy market and communities benefiting from sustainable energy projects. Technically, the website is built on WordPress using Elementor and Yoast SEO, with integrations such as Google Analytics and TranslatePress for multilingual support. The site demonstrates good mobile optimization, SEO practices, and moderate performance. Security measures include HTTPS enforcement and domain locking, though DNSSEC is not enabled. Cookie consent mechanisms are implemented, supporting GDPR compliance. From a security perspective, the site maintains a good posture with no critical vulnerabilities detected. However, there is room for improvement by enabling DNSSEC, publishing explicit security policies, and providing incident response contacts. No vulnerability disclosure or security.txt files were found, which could enhance transparency and trust. Overall, Cero Generation's website presents a trustworthy and professional digital presence aligned with its business objectives. Strategic recommendations include enhancing domain security with DNSSEC, formalizing security and incident response documentation, and expanding transparency around vulnerability disclosures to further strengthen security and compliance posture.
Scanned
NIS2 Art. 21(2)
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.

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.
Controls resources the browser is allowed to load
What to do: Implement a Content-Security-Policy appropriate for your application
These are the privacy signals visitors and data protection authorities look for under GDPR.
GDPR requires explicit consent for non-essential cookies
What to do: Implement a cookie consent banner that appears on first visit
TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.
Server supports weak protocols: TLSv1.1
What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

Each check with its score, findings and the evidence it collected.
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
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.
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, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
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.
