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

1 finding 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.

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

Teamleader operates in the competitive SaaS business software market targeting SMEs and agencies. Its competitive advantage lies in offering an all-in-one platform that simplifies business operations. Revenue is likely subscription-based with tiered pricing. The company has strategic partnerships and subsidiaries such as Dexxter and Teamleader One, expanding its product portfolio. The parent company Visma Group provides additional market strength. The website's content and testimonials indicate strong customer satisfaction and a focus on user experience. The multilingual approach and regional targeting demonstrate a well-planned market expansion strategy.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive cookie consent management, and use of security headers. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a public security policy, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness. The use of third-party analytics and marketing scripts is managed with user consent, aligning with GDPR requirements. Overall, the security maturity is good but could be enhanced by publishing dedicated security documentation and incident response procedures.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information to facilitate vulnerability reporting.
  3. Implement and publicize a vulnerability disclosure policy or security.txt file.
  4. Regularly review and audit third-party scripts and dependencies for security risks.
  5. Enhance transparency around data retention policies and user data handling.

Technical notes

Notes

The website uses a modern tech stack including Alpine.js and Vite for frontend performance and modularity. Cookiebot manages cookie consent, and Segment along with Google Analytics 4 provide analytics capabilities. The site is well-optimized for mobile and accessibility, with proper meta tags and structured data for SEO. Hosting details are not explicit but performance is fast. The site architecture supports multilingual content and dynamic navigation. There is no detected CMS, suggesting a custom or static site generation approach. Technical risks are minimal, but continuous monitoring of third-party scripts is advised to mitigate supply chain risks.
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.
