Security score

79/100

Risk levelLow

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

Clean Air Optima operates an e-commerce website specializing in air purifiers and related products targeted primarily at allergy sufferers and individuals sensitive to airborne allergens. The company positions itself as a niche retailer offering high-efficiency air purification solutions including air cleaners, ionizers, and robot vacuum cleaners with UV sterilization. The website content is professionally presented with a clear focus on product benefits for health-conscious consumers. Technically, the site employs modern web technologies including HTTPS, Google Tag Manager, and Cookiebot for cookie consent management, hosted on Azure CDN infrastructure. The site is mobile-optimized and SEO-friendly, providing a good user experience. Security posture is solid with HTTPS and cookie consent mechanisms, but lacks visible security headers and explicit security or privacy policy pages. WHOIS data is missing or unavailable, which raises concerns about domain legitimacy and registration status. Overall, the website is functional and trustworthy from a user perspective but would benefit from improved transparency regarding domain registration and privacy policies.

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 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. 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

The business operates in the retail sector focusing on air quality improvement products. Its market positioning targets allergy patients and health-conscious consumers, leveraging product specialization as a competitive advantage. The business model is direct-to-consumer e-commerce, with revenue streams from product sales. The website integrates marketing and analytics tools such as Google Analytics, Mailchimp, and Intercom, indicating active customer engagement and marketing efforts. The absence of clear contact information and company registration details limits full business intelligence assessment. No partnerships or subsidiaries are explicitly identified. The company appears to be a small-sized entity with consistent branding and good content quality.

Security posture

The website demonstrates a moderate to good security maturity level with enforced HTTPS and a comprehensive cookie consent mechanism that categorizes cookies by purpose and provider. However, the absence of security headers like Content-Security-Policy, X-Frame-Options, and a published security policy or incident response contact reduces the overall security posture. No vulnerabilities or exposed sensitive data were detected in the HTML content. Compliance with GDPR is partially indicated by the cookie consent but lacks explicit privacy policy documentation. Incident response readiness and vulnerability disclosure mechanisms are not evident. The security culture appears basic but functional, with room for improvement in transparency and technical controls.

Recommendations

  1. Publish a clear and comprehensive privacy policy and terms of service pages accessible from the website footer or main navigation.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  3. Provide explicit contact information including company email addresses and phone numbers for customer support and security incident reporting.
  4. Verify and update WHOIS domain registration information to ensure transparency and trustworthiness.
  5. Consider implementing a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.

Technical notes

Notes

The website is built using standard HTML5, CSS3, and JavaScript, with integration of third-party services such as Google Tag Manager and Cookiebot for analytics and cookie management. Hosting is provided via Azure CDN, ensuring good content delivery performance. The site is mobile responsive and includes SEO best practices such as meta tags and Open Graph data. Accessibility features are basic but present. No CMS or specific frameworks were detected from the provided HTML. Performance is moderate with asynchronous loading of scripts. Technical debt appears low, but the site could benefit from enhanced security headers and more explicit privacy and security documentation.
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.
