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

Plezi is a French-based technology company specializing in B2B marketing automation software designed to simplify and optimize lead generation, nurturing, and CRM synchronization. The company positions itself as a user-friendly and intelligent platform tailored for busy marketers and sales teams, offering a SaaS solution complemented by dedicated support and training services. The website is professionally designed, mobile-optimized, and leverages modern web technologies including WordPress, Yoast SEO, and Google Tag Manager for analytics and marketing. From a technical perspective, the site demonstrates good SEO practices and performance optimization but lacks explicit security headers and visible privacy or cookie policies, which are critical for GDPR compliance and user trust. The security posture is solid with HTTPS enforced and no exposed sensitive data, but improvements are recommended in security policy transparency and form security. Overall, the website is trustworthy and credible with consistent domain registration data and a clear business model. However, the absence of explicit privacy and cookie policies and security headers slightly lowers the privacy compliance and security posture scores. Strategic recommendations include implementing comprehensive privacy and cookie policies, enhancing security headers, and providing clear incident response contacts to improve compliance and user trust.

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 B2B companies, marketing professionals, sales teams, and agencies. Its competitive advantage lies in simplifying complex marketing automation workflows and providing intelligent campaign management. The business model is SaaS-based with additional consulting and training services, generating revenue from subscriptions and professional services. The company demonstrates growth with over 4,000 marketers using its platform and maintains a strong partnership ecosystem visible through social media and client logos. The website content and structured data indicate a focus on French and international markets with English language support. Plezi's strategic positioning emphasizes ease of use, integration with CRM systems, and alignment between marketing and sales teams.

Security posture

The security maturity level of Plezi's website is moderate to good. HTTPS is properly implemented, ensuring encrypted communications. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces protection against common web attacks. No visible vulnerabilities or exposed sensitive data were detected. The site uses third-party scripts including Google Tag Manager and analytics services, which require ongoing monitoring for security risks. There is no public incident response or vulnerability disclosure information, which could hinder rapid response to security incidents. GDPR compliance indicators are weak due to missing privacy and cookie policies. Overall, Plezi should enhance its security posture by adopting recommended headers, publishing security policies, and establishing clear incident response channels.

Recommendations

  1. Implement and publicly disclose comprehensive privacy and cookie policies to ensure GDPR compliance.
  2. Add essential security headers such as CSP, HSTS, and X-Frame-Options to strengthen web security.
  3. Establish and publish incident response and vulnerability disclosure contacts to improve security readiness.
  4. Ensure all web forms include anti-CSRF tokens and input validation to prevent injection attacks.
  5. Regularly audit third-party scripts and dependencies to mitigate supply chain risks.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including Yoast SEO for search optimization, WPBakery Page Builder for layout management, and WP Rocket for caching and performance. Google Fonts and jQuery are used for styling and scripting. Google Tag Manager integrates analytics and marketing pixels, including Google Analytics and Google Ads tracking. The site is mobile-optimized with responsive design and uses structured data (JSON-LD) for enhanced SEO and social media integration. Performance is moderate with caching enabled but could benefit from further optimization. No hosting provider details were explicitly detected. Accessibility features are basic and could be improved for compliance with standards such as WCAG.
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.
