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

    • 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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"

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

Sto operates in the energy and manufacturing sectors, focusing on sustainable building materials and insulation technologies. Its business model revolves around product innovation and comprehensive solutions for building envelopes. The company leverages partnerships with major payment providers and marketing platforms to enhance customer experience and outreach. The website's integration with Salesforce and marketing tools indicates a sophisticated CRM and digital marketing strategy. The absence of privacy protection in WHOIS and consistent registration data reinforce the company's transparency and legitimacy. Growth potential is supported by strong branding and a clear market niche in energy-efficient construction.

Security posture

The website exhibits a mature security posture with enforced HTTPS, a robust Content-Security-Policy, and use of consent management tools. No security.txt or explicit incident response policies were found, representing an area for improvement. Third-party scripts are from reputable sources, but continuous monitoring is recommended to mitigate supply chain risks. The site avoids exposing sensitive data and employs standard security best practices. GDPR compliance is evident through privacy and cookie policies. Overall, the security maturity is good, with recommendations to formalize incident response and vulnerability disclosure processes.

Recommendations

  1. Publish a dedicated security policy and incident response page to enhance transparency.
  2. Implement a security.txt file to facilitate vulnerability reporting.
  3. Conduct regular audits of third-party scripts and dependencies for vulnerabilities.
  4. Improve accessibility features to meet higher compliance standards.
  5. Maintain and update privacy and cookie policies in line with evolving regulations.

Technical notes

Notes

The website is built on Salesforce Experience Cloud using Aura and Lightning frameworks, indicating a modern and scalable infrastructure. Integration with Usercentrics for consent management and multiple payment gateways (Stripe, PayPal, Adyen) shows advanced e-commerce capabilities. Performance is moderate, with room for optimization in loading times. SEO and mobile optimization are good, supported by proper meta tags and responsive design. The technical stack is robust but reliant on third-party services, necessitating vigilant security monitoring. Opportunities exist to enhance accessibility and streamline performance for better user experience.
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.
