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

Sizera is a technology-driven company offering AI-powered clothing size and fit solutions targeted at fashion retailers. Their platform aims to increase online conversions, reduce product returns, and optimize production processes by leveraging data and artificial intelligence. The website presents a professional and modern interface built with Next.js and React, indicating a contemporary technical infrastructure. However, the absence of WHOIS registration data raises concerns about the domain's legitimacy and registration status. Security posture is weak due to missing HTTPS verification, lack of security headers, and absence of privacy and cookie policies. Overall, while the business concept is clear and relevant to the retail sector, the technical and security maturity requires significant improvement to build trust and ensure compliance.

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. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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';…

  3. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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 retail sector, specifically focusing on apparel and fashion e-commerce. Their business model is B2B SaaS, providing AI-driven size recommendation services to fashion retailers to improve customer experience and reduce operational costs related to returns. The website content is concise and targeted, but lacks detailed business information such as company history, legal entity data, or contact details. No partnerships or certifications are disclosed, limiting insight into their market positioning or competitive advantages. The absence of WHOIS data and contact information may hinder customer trust and business credibility.

Security posture

The website currently exhibits a low security maturity level. There is no evidence of HTTPS enforcement or security headers, which are critical for protecting user data and preventing common web attacks. No privacy or cookie policies are published, indicating potential non-compliance with GDPR and other privacy regulations. The lack of incident response or vulnerability disclosure information further reduces transparency and preparedness for security incidents. To improve, the company should implement robust SSL/TLS configurations, add standard security headers, publish comprehensive privacy and cookie policies, and establish clear incident response channels.

Recommendations

  1. Implement HTTPS with a valid SSL certificate and enforce secure connections site-wide.
  2. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish detailed privacy and cookie policies to demonstrate compliance with GDPR and other regulations.
  4. Provide clear contact information including support emails and phone numbers to enhance business credibility.
  5. Establish a vulnerability disclosure program and incident response contact to improve security transparency.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, which support server-side rendering and improved performance. The site appears mobile-optimized with a clean design and good user experience. However, no CMS or hosting provider information is available. Performance is moderate based on script loading patterns. Accessibility features are basic, and SEO optimization is minimal with limited meta tags and no structured data. There is no evidence of analytics or tracking tools, which could be an opportunity for future enhancement. Technical risks include lack of HTTPS and security headers, which could expose users to data interception or attacks.
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.
