Spotler is a Dutch technology company founded in 2017 specializing in data-driven marketing software solutions. Their product suite includes customer data platforms, AI-powered chatbots, CRM, email marketing automation, and social media management tools. The company serves over 5,000 organizations, positioning itself as a trusted mid-sized player in the marketing technology sector. The website is professionally designed, multilingual, and rich in content including customer case studies and detailed product information. Technically, the site is built on WordPress, uses Cloudflare for hosting and CDN, and integrates modern marketing tools like Google Tag Manager. However, the security posture is weak due to the absence of a valid SSL certificate and lack of TLS support, which is a critical issue for trust and compliance. Privacy and cookie policies are present and GDPR compliant, and the company holds ISO 27001 certification, indicating a commitment to information security. Overall, the website is credible and professional but requires urgent security improvements to protect user data and enhance 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

7 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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

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.

Security posture

The current security maturity level is low due to the lack of a valid SSL certificate and disabled TLS protocols, exposing the site to risks such as data interception and loss of user trust. While the company demonstrates compliance with ISO 27001 and GDPR through policies and certifications, the technical implementation of security controls on the website is insufficient. No incident response or vulnerability disclosure information is publicly available, which may indicate limited readiness for security incidents. The use of Cloudflare provides some protection and caching benefits, but without HTTPS, these are undermined. The absence of HSTS, OCSP stapling, and session resumption further weakens the security posture. Overall, the business impact of these vulnerabilities is significant, potentially affecting customer confidence and regulatory compliance.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the entire website.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable deprecated protocols.
  3. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  4. Correct and properly configure CAA DNS records to restrict certificate issuance.
  5. Enable OCSP stapling and session resumption to improve security and performance.
  6. Publish a vulnerability disclosure policy and incident response contact information to enhance transparency and readiness.
  7. Conduct regular security audits and penetration testing to identify and remediate vulnerabilities.
  8. Enhance accessibility features and mobile optimization to improve user experience.
  9. Maintain comprehensive and up-to-date privacy and cookie policies with clear consent mechanisms.
  10. Leverage trust signals such as certifications and customer testimonials prominently to reinforce credibility.
Technical notes

Notes

The website is built on WordPress CMS with a modern and professional design. It uses Cloudflare as a hosting and CDN provider, integrating Google Tag Manager and FontAwesome for analytics and UI enhancements. Multilingual support is implemented via WPML. The site includes custom plugins such as Spotler Subject Line Analyser and AddToAny for sharing. Performance data is unavailable, but the site appears well-structured with clear navigation and SEO optimization. However, the absence of HTTPS and TLS protocols is a critical technical debt. The DNS configuration is mostly standard but contains malformed CAA records. The site would benefit from improved security configurations and performance monitoring to reduce technical risks impacting business operations.
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.
