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

Diffuse Tools is a small technology company based in the Netherlands, founded in 2020, offering easy-to-implement customizable widgets and code snippets to enhance websites without requiring coding skills. Their product suite includes Cookie Notice, Store Locator, Donations, and Contact Button widgets, targeting web developers and website owners seeking to improve user experience and compliance. The company positions itself as a niche SaaS provider with a professional and modern web presence. Technically, the website is built using Next.js and React frameworks, hosted with reliable providers, and optimized for performance and mobile responsiveness. The use of Google Tag Manager indicates a moderate level of analytics and marketing integration. Security-wise, the site enforces HTTPS and domain transfer protections but lacks DNSSEC and visible security headers, and does not publish a formal security policy or incident response contacts. Overall, the site is professional, trustworthy, and compliant with privacy regulations, though there is room for improvement in security transparency and DNS security. The domain registration data aligns well with the business claims, supporting legitimacy.

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

4 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"

    • 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. 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.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Diffuse Interactive operates in the technology sector with a focus on SaaS products for website enhancement. Their business model revolves around providing customizable widgets that simplify website compliance and functionality. The company targets web developers and digital marketers, offering tools that require no coding, which is a competitive advantage in ease of use. The presence of a partner domain (diffuse.nl) suggests a broader organizational structure. Revenue likely derives from subscriptions or usage-based fees for widget services. The company maintains a professional online presence with clear product offerings and support documentation, indicating a growth-oriented and customer-focused approach.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and domain transfer protections in place. However, the absence of DNSSEC and security headers such as Content-Security-Policy and Strict-Transport-Security reduces the overall security posture. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published security policy or incident response contact limits transparency and readiness perception. Privacy compliance is supported by clear privacy and cookie policies with consent mechanisms. Overall, the security posture is adequate for a small SaaS provider but could be enhanced by implementing additional DNS and HTTP security measures and publishing formal security documentation.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a dedicated security policy page and provide incident response contact information to improve transparency and trust.
  4. Add a vulnerability disclosure or security.txt file to facilitate responsible reporting of security issues.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.

Technical notes

Notes

The website is built on a modern React and Next.js stack, leveraging server-side rendering and static export for performance. It uses Google Fonts and Google Tag Manager for typography and analytics respectively. Hosting and DNS are managed by reputable providers, with Cloudflare DNS servers and Registrar.eu as the registrar. The site is mobile-optimized with responsive design and good accessibility practices. Performance is fast with preloading of key assets and deferred script loading. No CMS is detected, indicating a custom or framework-based build. Technical risks include missing DNSSEC and lack of security headers, which should be addressed to reduce attack surface. Overall, the technical infrastructure is modern, performant, and well-implemented for a small SaaS business.
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.
