Low risk. 2 critical or high findings in Security headers and GDPR outside view.

Security score

76/100

Risk levelLow

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

InteractiveCalculator.com is a technology-focused SaaS provider offering an interactive calculator builder that users can embed on their websites. The service targets website owners and developers seeking customizable calculator solutions to enhance user engagement. The website demonstrates a professional design using modern CSS frameworks and iconography, indicating a moderate level of digital maturity. However, the absence of WHOIS registration data raises concerns about domain legitimacy and ownership transparency. Security posture is basic with HTTPS implied but lacking explicit security headers and policies. Privacy compliance is minimal with no visible privacy or cookie policies, and no contact information is provided, limiting trust and compliance assurance. Overall, the website is functional and visually appealing but requires improvements in security, privacy, and legitimacy transparency to reduce risk and enhance credibility.

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

2 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

  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

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

The business operates in the technology sector, providing a niche SaaS product for interactive calculators. Its business model revolves around offering embeddable calculators likely monetized via subscriptions or usage fees. The target market includes small to medium-sized businesses and website owners. The lack of detailed company information, certifications, or contact details limits insight into its market positioning and growth potential. The website's clean design and use of trusted frameworks suggest a focus on quality user experience. However, the absence of WHOIS data and privacy policies may hinder trust-building with potential customers and partners.

Security posture

Security maturity is basic. The site uses HTTPS, which is mandatory, but no security headers such as Content-Security-Policy or X-Frame-Options were detected. There is no evidence of vulnerability disclosures, incident response contacts, or security certifications. The lack of privacy and cookie policies indicates compliance gaps with GDPR and other data protection regulations. No analytics or tracking scripts were found, which reduces privacy risks but also limits marketing insights. The domain's WHOIS data absence is a significant red flag, potentially indicating registration issues or privacy protection that is not justified. Overall, the security posture requires enhancements in policy transparency, technical controls, and compliance documentation.

Recommendations

  1. Register the domain properly and ensure WHOIS data is available and accurate to improve legitimacy and trust.
  2. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements and implement consent mechanisms.
  3. Add terms of service and security incident response information to demonstrate governance and readiness.
  4. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to harden the site.
  5. Provide clear contact information including company emails and phone numbers to enhance business credibility and customer trust.

Technical notes

Notes

The website is built with modern front-end technologies including Bulma CSS and Font Awesome icons, indicating a contemporary design approach. The HTML structure is valid and the site is mobile optimized with responsive design elements. Performance is moderate based on the CSS and script usage. No CMS or hosting provider information was detected. The absence of analytics or tracking scripts suggests minimal data collection. Technical debt appears low but the lack of security headers and policy pages indicates areas for modernization and compliance improvements. Overall, the technical infrastructure supports a good user experience but requires enhancements in security and privacy features.
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.
