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

6 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 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';…

  2. 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

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

Plezi operates in the competitive marketing automation sector, targeting mid-sized B2B companies and agencies. Their business model is subscription-based SaaS, offering features like lead generation, lead nurturing, campaign management, and CRM integration. The company emphasizes ease of use and intelligent automation to differentiate from complex competitors. The website highlights over 4,000 marketers as users, indicating a solid customer base. Social media integration and client logos support credibility. The lack of visible contact details and WHOIS transparency slightly limit direct trust but are common in SaaS businesses. Plezi's ecosystem includes partnerships and training services, enhancing customer engagement and retention.

Security posture

The website uses HTTPS with a valid SSL certificate and employs Google Tag Manager and Axeptio for analytics and cookie consent, respectively. However, no explicit security headers (e.g., CSP, HSTS) were detected in the provided data. No exposed sensitive information or vulnerable libraries were found. The absence of published security policies, incident response contacts, or vulnerability disclosure mechanisms suggests room for improvement in security governance and transparency. The site does not appear to be behind a WAF or show blocking behavior, indicating stable accessibility. Overall, the security posture is good but could be enhanced with formal policies and headers.

Recommendations

  1. Publish comprehensive privacy and cookie policies with clear links on the website.
  2. Implement and expose security headers such as Content-Security-Policy, X-Frame-Options, and HSTS.
  3. Create and publish a security incident response plan and vulnerability disclosure policy, including a security.txt file.
  4. Provide clear contact information for data protection officer or privacy-related inquiries.
  5. Regularly audit third-party scripts and plugins to ensure no vulnerabilities or privacy issues.

Technical notes

Notes

The website is built on WordPress using the Salient theme and WPBakery Page Builder, enhanced with Yoast SEO for search optimization and WP Rocket for performance. It uses Google Tag Manager and Google Analytics for tracking, and Axeptio for cookie consent management. The site is mobile-optimized with responsive design and good accessibility features. The use of modern fonts, SVG icons, and lazy loading images contributes to performance and user experience. No hosting provider details were found, but the site appears fast and well-maintained. Technical debt is low, but adding security headers and formal privacy mechanisms would improve the technical maturity.
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.
