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

Poshmark.ca is a Canadian localized e-commerce platform specializing in the buying and selling of fashion, home decor, beauty, and related lifestyle products. The website leverages modern web technologies such as Vue.js and is hosted on Amazon AWS infrastructure with Cloudfront CDN, ensuring good performance and scalability. The platform targets consumers interested in secondhand and new fashion and lifestyle goods within Canada, positioning itself as a significant player in the online resale marketplace. The domain is well-established since 2013, indicating a mature business presence in the market. From a technical perspective, the website demonstrates a modern frontend framework usage and good mobile optimization. SEO is supported by structured data (JSON-LD) and Open Graph metadata, enhancing search engine visibility and social media sharing. However, there is a lack of visible security headers and no DNSSEC enabled, which are areas for improvement to strengthen security posture. Privacy compliance is weak due to the absence of explicit privacy and cookie policies or consent mechanisms in the analyzed content. Security-wise, the site uses HTTPS with a valid SSL configuration and domain registration statuses that prevent unauthorized transfers or deletions, which are positive indicators. The WHOIS data shows privacy protection for registrant details, which is common and justified for commercial entities. No critical vulnerabilities or exposed sensitive data were detected in the provided content. However, the absence of published security policies, incident response contacts, and vulnerability disclosure mechanisms suggests room for enhancing transparency and trust. Overall, Poshmark.ca presents a professional and trustworthy e-commerce platform with solid technical foundations but requires improvements in privacy compliance and security best practices to meet higher standards and regulatory requirements. Strategic recommendations include enabling DNSSEC, publishing comprehensive privacy and cookie policies with consent mechanisms, implementing security headers, and providing clear security and incident response information to users and stakeholders.

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

5 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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"

  3. GDPR outside view

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

    • 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

    • 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

  4. 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"

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

Poshmark operates as a large-scale e-commerce marketplace focused on fashion and lifestyle resale in Canada. Its business model centers on peer-to-peer sales, enabling users to buy and sell new and used items. The platform benefits from a strong brand presence and a mature domain age, supporting trust and market penetration. Revenue streams likely include transaction fees and promotional services. The target customer segment includes fashion-conscious consumers seeking affordable and sustainable shopping options. The company leverages partnerships with major technology providers such as AWS for hosting and Google for analytics and marketing. Growth indicators include localized domain presence and continuous platform updates. The absence of explicit partner or subsidiary domains in the analyzed content suggests a focused operational scope within the Poshmark brand ecosystem.

Security posture

The security posture of Poshmark.ca is moderate with key strengths including HTTPS enforcement, domain registration protections, and use of reputable hosting infrastructure. However, the lack of DNSSEC and security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the defense-in-depth capabilities. No evidence of exposed sensitive data or vulnerable libraries was found, indicating good maintenance practices. The absence of published security policies, incident response contacts, and vulnerability disclosure programs limits transparency and user assurance. Compliance with GDPR and other privacy regulations is unclear due to missing privacy and cookie policies. Overall, the platform is secure but would benefit from enhanced security controls and compliance documentation.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve DNS security.
  2. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements and implement a cookie consent mechanism.
  3. Add essential security headers (CSP, HSTS, X-Frame-Options, X-Content-Type-Options) to strengthen web security posture.
  4. Provide a publicly accessible security policy and incident response contact information to improve transparency and trust.
  5. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.

Technical notes

Notes

The website is built using Vue.js, a modern JavaScript framework, and is served via AWS Cloudfront CDN, ensuring fast content delivery and scalability. Fonts are loaded from Google Fonts with preload hints for performance optimization. Google Tag Manager is used for analytics and marketing tracking. The site uses structured data (JSON-LD) for SEO enhancement and Open Graph tags for social media integration. The domain is registered with Go Daddy Domains Canada, Inc, with privacy protection enabled. The site is mobile optimized with responsive design and uses Roboto font family for consistent branding. No CMS was explicitly detected. Performance is likely fast due to CDN usage and asset preloading. Accessibility features are basic but present. SEO is good with proper meta tags and structured data. Technical debt appears low, but security header implementation is missing, representing a modernization opportunity.
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.
