Security score

75/100

Risk levelMedium

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

Rainbow Ultrasonics is a specialized manufacturing company providing advanced plastic joining and ultrasonic welding solutions primarily for medical, military, aerospace, and consumer goods industries. With over 40 years of experience, the company positions itself as a trusted partner delivering precision-engineered, bespoke machinery and consultancy services to a global clientele. The website reflects a professional and consistent brand image with clear communication of services and contact information. Technically, the site uses modern web technologies including jQuery, service workers, and Snowplow analytics, hosted on a CDN infrastructure ensuring moderate performance and good mobile optimization. Security posture is solid with HTTPS and service worker usage, but lacks some security headers and explicit cookie consent mechanisms. WHOIS data for the domain is unavailable, which reduces domain trustworthiness and calls for further verification. Overall, the site is safe, business-focused, and well-structured, suitable for its industrial target audience.

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. 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

  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 company operates in the manufacturing sector with a focus on plastic joining technologies serving diverse sectors such as healthcare, military, aerospace, and consumer goods. Its business model is B2B, offering equipment sales, bespoke machinery design, and consultancy. The firm leverages its long-standing industry experience as a competitive advantage. Contact details and policies are clearly presented, supporting customer engagement. The absence of WHOIS data is a notable gap but does not detract from the professional presentation and market positioning. The company appears to maintain a moderate-sized operation with a global reach and a focus on technical excellence and innovation.

Security posture

The website enforces HTTPS and employs service workers, indicating a modern approach to security and performance. However, it lacks important HTTP security headers such as Content-Security-Policy, X-Frame-Options, and HSTS, which are recommended to mitigate common web vulnerabilities. No forms or input fields were detected, reducing immediate risk from input-based attacks. Analytics tracking is done via Snowplow, with moderate user tracking levels and basic privacy compliance. No incident response or vulnerability disclosure information is provided, which could be improved to enhance transparency and preparedness. Overall, the security posture is good but could benefit from implementing additional headers and explicit privacy consent mechanisms.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and HSTS to strengthen web security.
  2. Add explicit cookie consent mechanisms to comply with privacy regulations and improve user trust.
  3. Verify and update WHOIS domain registration information to enhance domain legitimacy and trust.
  4. Consider publishing an incident response policy and vulnerability disclosure program to improve security transparency.
  5. Regularly audit third-party scripts and analytics tools to ensure no vulnerabilities or privacy issues.

Technical notes

Notes

The website is built on a modern tech stack including jQuery 3.7.0, Skrollr for parallax effects, and Snowplow for analytics. It uses service workers for offline support and performance improvements. Fonts are served via Google Fonts, and icons via FontAwesome. The site is hosted on a CDN infrastructure ensuring good availability and moderate performance. The HTML and CSS are valid and well-structured, with responsive design for mobile devices. However, the site lacks some advanced accessibility features and security headers. There is no detected CMS beyond the multiscreensite platform. Overall, the technical implementation is solid with room for security and privacy enhancements.
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.
