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

Marketizer.pl is a Polish technology company specializing in B2B lead identification and analytics solutions. Their platform provides businesses with detailed insights into potential clients visiting their websites, including contact data and behavioral profiles, enabling effective lead generation and marketing. The company operates on a SaaS subscription model with tiered pricing and offers a free trial period to attract customers. The website is professionally designed, mobile-optimized, and provides clear navigation and relevant content tailored to entrepreneurs and businesses seeking B2B growth. Technically, the website employs modern JavaScript libraries such as jQuery and Slick Carousel, integrates Google Analytics and Google Tag Manager for tracking, and uses Google Ads remarketing services. The site is served over HTTPS with good SSL configuration but lacks DNSSEC and explicit security headers, which are recommended for enhanced security. The absence of a cookie consent mechanism is a notable privacy compliance gap. Contact information is clearly presented, including a physical address and company email, supporting business credibility. From a security perspective, the site demonstrates basic best practices such as secure form submissions and no exposed sensitive data. However, improvements are needed in DNS security and HTTP security headers. No evidence of malware, phishing, or other critical vulnerabilities was found. Privacy policies and terms of service are available, indicating compliance awareness, though cookie consent implementation should be improved. Overall, Marketizer.pl presents a trustworthy and professional online presence with moderate technical maturity and security posture. Strategic enhancements in security headers, DNSSEC, and privacy compliance would strengthen their risk profile and customer 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

10 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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

Marketizer.pl occupies a niche in the Polish B2B marketing technology sector, offering a specialized lead identification and analytics platform. Their competitive advantage lies in providing detailed business client profiles and real-time notifications, which help clients accelerate sales cycles. The subscription-based business model with tiered plans and free trials supports customer acquisition and retention. The company targets small to medium-sized enterprises and marketing agencies seeking to improve lead quality and conversion rates. Partnerships appear to be encouraged through a partner program, though no explicit partner domains were identified. The company demonstrates transparency with clear contact details and legal documentation, supporting credibility and growth potential in a competitive market.

Security posture

The website's security posture is moderate. HTTPS is properly implemented, ensuring encrypted communications. However, the lack of DNSSEC leaves the domain vulnerable to DNS spoofing attacks. The absence of HTTP security headers such as Content-Security-Policy and Strict-Transport-Security reduces protection against common web attacks like XSS and clickjacking. No incident response or security policy information is published, which may hinder rapid response to security events. Forms use POST methods but no explicit anti-CSRF or input validation details are visible. Privacy compliance is partial, with privacy and terms documents present but no cookie consent mechanism. Overall, the site is secure enough for general business use but would benefit from enhanced security controls and transparency.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS integrity and prevent spoofing.
  2. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add a cookie consent banner/mechanism to comply with GDPR and other privacy regulations.
  4. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website uses a modern but relatively simple technology stack centered on jQuery and Slick Carousel for UI components. Google Analytics and Google Tag Manager are integrated for analytics and marketing tracking. The site is served over HTTPS with a valid SSL certificate, but DNSSEC is not enabled, which is a missed opportunity for DNS security. No CMS or major frameworks were detected, suggesting a custom or lightweight implementation. Performance appears moderate with asynchronous loading of scripts and CDN usage for libraries. Mobile optimization is good, with responsive design meta tags and mobile-friendly navigation. Accessibility is basic, with no explicit ARIA roles or advanced accessibility features detected. SEO is supported by proper meta tags and Open Graph data. Overall, the technical implementation is solid but could be enhanced with modern security and accessibility best practices.
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.
