Risk levelMedium

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

Saltfoss is a newly founded company (2025) focused on innovating nuclear energy technology by developing a fundamentally different nuclear power plant concept. Their flagship product is the Compact Molten Salt Reactor (CMSR) deployed on modular floating power barges designed for sustainability, safety, and cost-effectiveness. The company targets energy market stakeholders and aims to revolutionize energy markets by providing abundant, affordable, and low-emission energy solutions. The website is professionally designed using WordPress and Elementor, with good SEO and mobile optimization. Security posture is adequate with HTTPS and domain transfer protections, but lacks advanced security headers and published security policies. Privacy compliance is partial, with a cookie consent mechanism but no visible privacy or terms policies. Contact information is not explicitly provided, which may impact user trust. Overall, the website and domain registration indicate a legitimate and transparent business entity with room for improvement in security and compliance documentation.

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. 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
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

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

    • 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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Saltfoss positions itself as an innovator in the energy sector, specifically nuclear power technology. Their business model revolves around developing and deploying modular nuclear power plants on floating barges, targeting markets seeking sustainable and cost-effective energy solutions. The company appears small and newly established, with a focus on partnerships and co-development opportunities. The website content and press releases suggest active engagement in market updates and investor relations. The use of modern web technologies and SEO tools indicates a digitally mature approach. However, the absence of explicit contact details and formal policies may limit full business credibility. No direct partnerships or subsidiaries are identified from the website content.

Security posture

The website employs HTTPS and has domain transfer protections, which are positive security indicators. However, no security headers such as Content-Security-Policy, X-Frame-Options, or Strict-Transport-Security were detected, representing a security best practice gap. There is no published security policy, incident response plan, or vulnerability disclosure mechanism, which limits transparency and preparedness for security incidents. The use of popular WordPress plugins and themes suggests a standard security baseline but requires regular updates and monitoring to avoid vulnerabilities. No exposed sensitive data or obvious vulnerabilities were found in the HTML content. Overall, the security posture is moderate but could be significantly improved by implementing recommended security headers and publishing security policies.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Publish a comprehensive privacy policy and terms of service to improve legal compliance and user trust.
  3. Add explicit contact information including company email and phone numbers to facilitate communication and support.
  4. Establish and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Enable DNSSEC for the domain to improve DNS security and prevent spoofing.

Technical notes

Notes

The website is built on WordPress using the Astra theme and Elementor page builder, leveraging modern web technologies such as jQuery and various plugins for SEO, GDPR compliance, and video popups. The site is mobile optimized and uses Google Fonts for typography. Performance is moderate with no major issues detected. The domain uses simply.com name servers and is registered with Name.com, Inc. The website employs HTTPS with a valid SSL certificate. However, the absence of security headers and DNSSEC indicates areas for technical security enhancement. The website's SEO is supported by Yoast SEO plugin and structured data in JSON-LD format, improving search engine visibility. Overall, the technical infrastructure is solid but could benefit from additional security hardening and accessibility improvements.
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.
