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

Delcros is a French company specializing in surface treatment of stainless steel and aluminum parts, with a history dating back to 1965. The company offers a range of industrial services including chemical pickling, passivation, electrolytic polishing, tribofinition, microblasting, and anodization. Recently acquired by ANODUR, Delcros has expanded its market presence and is recognized for compliance with nuclear industry standards such as ISO 9001:2015 and ISO 19443:2018. The website targets professional clients in the energy sector and emphasizes quality and reactivity as key differentiators. Technically, the website is built on WordPress using Elementor and Yoast SEO, with modern web technologies and a cookie consent mechanism implemented via Tarteaucitron. Security posture is adequate with HTTPS enforced, but lacks visible security headers and explicit privacy policy documentation. No contact emails or phone numbers are directly visible, which may impact user trust and compliance. Overall, the site is professional and well-structured, but could improve transparency and security practices.

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

7 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

    • 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

  2. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

    • 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

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

Delcros operates in the specialized industrial surface treatment sector, serving professional clients primarily in the energy and nuclear industries. The company leverages certifications and compliance with stringent nuclear codes to position itself as a reliable and quality-focused partner. The acquisition by ANODUR suggests strategic growth and consolidation in the market. The business model is B2B, focusing on technical services with a strong emphasis on quality assurance and regulatory compliance. The website reflects a mature digital presence with SEO and multilingual support, but lacks direct contact details which could hinder lead generation and customer engagement. Partnerships with web agencies indicate investment in digital marketing and brand presence.

Security posture

The website enforces HTTPS and uses a cookie consent tool, indicating awareness of privacy and security requirements. However, the absence of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security posture. No incident response or vulnerability disclosure information is provided, which limits transparency in security management. The use of third-party scripts like Google Tag Manager and social media integrations introduces potential tracking and privacy concerns, though these are managed via consent. The lack of visible contact information for security or abuse reporting is a gap in incident response readiness. Overall, the security maturity is moderate but could be enhanced with additional controls and transparency.

Recommendations

  1. Publish a comprehensive privacy policy page detailing data handling and user rights.
  2. Implement and verify security headers (CSP, HSTS, X-Frame-Options) to enhance protection.
  3. Add clear contact information including emails and phone numbers for customer and security inquiries.
  4. Establish and publicize an incident response and vulnerability disclosure process.
  5. Conduct regular security audits of third-party scripts and plugins to mitigate risks.

Technical notes

Notes

The website is built on a modern WordPress platform using Elementor for page building and Yoast SEO for optimization. It employs standard web technologies including jQuery and Google Tag Manager for analytics and marketing. The site is mobile responsive and uses lazy loading for images to improve performance. However, no explicit hosting provider information is available. Performance is moderate with room for improvement in accessibility features. The cookie consent mechanism is robust, leveraging Tarteaucitron for GDPR compliance. Technical debt appears low, but the absence of security headers and incomplete privacy documentation represent modernization opportunities and risks that could impact business operations if not addressed.
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.
