Low risk. 3 critical or high findings in Security headers, GDPR outside view and 1 other check.

Security score

84/100

Risk levelLow

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

Dentsu Finland operates as part of the global dentsu network, providing marketing, advertising, and business transformation services. The website content emphasizes brand growth and responsible business development in a constantly changing world. The company targets brands and businesses seeking to grow and transform their operations. The website is professionally designed, mobile-optimized, and uses modern analytics and tracking technologies such as Microsoft Clarity and Google Tag Manager. However, the absence of visible privacy, cookie, and terms of service policies, as well as lack of explicit contact information, limits the transparency and user trust aspects. The WHOIS data for the domain is unavailable, which reduces confidence in domain registration legitimacy but does not necessarily indicate malicious intent given the professional web presence.

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

3 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 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 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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Dentsu is positioned as a leading media and marketing communications company with a focus on digital transformation and responsible business practices. The business model revolves around providing strategic marketing services to brands, helping them grow and adapt in evolving markets. The website targets Finnish audiences, reflecting localized content and language. The company likely operates at an enterprise scale given the global dentsu brand association. The lack of detailed business registration or VAT information on the website limits deeper business intelligence. The presence of social media links and canonical URLs supports a credible digital footprint.

Security posture

The website uses HTTPS and includes modern tracking scripts but lacks visible security headers and explicit security policies. No vulnerability disclosure or security.txt files were found, and no incident response contacts are provided. The absence of privacy and cookie policies indicates potential compliance gaps with GDPR and other privacy regulations. While no critical vulnerabilities or exposed sensitive data were detected in the HTML content, the security posture is moderate and could be improved by implementing recommended security headers, publishing privacy and cookie policies with consent mechanisms, and providing clear security incident contacts.

Recommendations

  1. Implement comprehensive privacy and cookie policies with user consent mechanisms to improve GDPR compliance.
  2. Publish a security policy and incident response contact information to enhance transparency and trust.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen security posture.
  4. Consider publishing a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Enhance contact information visibility including verified company emails and phone numbers for user support and trust.

Technical notes

Notes

The website employs modern JavaScript libraries and tracking tools including Microsoft Clarity and Google Tag Manager, indicating a mature digital analytics setup. The HTML structure includes canonical tags and meta tags optimized for SEO. The site loads external CSS and JS from reputable CDNs. Mobile optimization appears good, and the design is professional. However, no CMS or hosting provider information was detected. Performance is moderate based on script usage and content size. Accessibility features are basic but present. Technical debt or outdated technologies were not evident in the provided content.
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.
