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

Adalyser is a specialized SaaS platform focused on simplifying and automating the TV advertising lifecycle, including research, planning, measurement, optimization, and management. The platform integrates industry-standard data sources such as CARIA and BARB to provide up-to-date campaign insights and automate schedule loading and pricing. The website reflects a mature technical infrastructure using modern JavaScript frameworks like Vue.js and Element UI, combined with standard analytics and cookie consent mechanisms. Security posture is adequate with HTTPS and some best practices, though improvements in security headers and DNSSEC are recommended. Privacy compliance is basic, with cookie consent implemented but no visible privacy or terms pages. Overall, the website presents a professional and trustworthy image consistent with a medium-sized media technology company founded in 2011.

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

4 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 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';…

  2. 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

Adalyser operates in the media sector, targeting TV advertisers and marketing professionals seeking an integrated platform for campaign lifecycle management. Its competitive advantage lies in automation and integration with key industry data providers, enabling efficient campaign planning and real-time optimization. The business model is SaaS-based, focusing on recurring revenue from platform subscriptions. The company has processed significant advertising spend, indicating market traction. The website content and WHOIS data align well, supporting credibility. However, the absence of explicit contact emails and phone numbers on the site suggests reliance on contact forms for lead generation. No partnerships or subsidiaries were identified from the domain data.

Security posture

The website employs HTTPS and integrates Google Tag Manager for analytics, with a cookie consent mechanism indicating awareness of privacy regulations. However, the lack of visible security headers and DNSSEC implementation represents areas for enhancement. No exposed sensitive data or vulnerable libraries were detected in the provided content. The absence of a published security policy or incident response contacts limits transparency in security governance. Overall, the security maturity is moderate, suitable for a SaaS platform but with room for improvement to meet higher compliance standards such as ISO 27001 or NIST frameworks.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service pages to improve privacy compliance and user trust.
  2. Add security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-Content-Type-Options to enhance security posture.
  3. Enable DNSSEC on the domain to protect against DNS spoofing and improve domain security.
  4. Publish a security policy and incident response contact information, including abuse and security email addresses, to demonstrate security governance and readiness.
  5. Consider adding direct contact information such as verified company emails and phone numbers to improve business credibility and user accessibility.

Technical notes

Notes

The website uses a modern front-end stack with Vue.js and Element UI, supported by jQuery libraries for legacy compatibility. It employs Google Tag Manager for analytics and has a cookie consent script indicating GDPR awareness. Hosting appears to be managed via DNS Made Easy nameservers, suggesting reliable DNS infrastructure. Performance is moderate with standard optimization techniques. Mobile optimization and accessibility are good but could be further enhanced. No CMS was detected, indicating a custom or static site approach. The technical implementation supports a professional user experience but would benefit from additional security hardening and SEO improvements.
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.
