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

2 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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

Taboola operates in the technology and media sectors, focusing on native advertising and content recommendation services. Their business model revolves around performance marketing, utilizing AI and first-party data to optimize ad targeting and campaign management. The company has a global reach and enterprise scale, founded in 2007, with subsidiaries such as Connexity enhancing their service offerings. Their partnership ecosystem includes Skimlinks and other marketing partners, reinforcing their market presence. The website showcases strong branding consistency, client success stories, and certifications that build trust. Revenue streams likely include advertising fees, referral programs, and technology licensing. The target customers are advertisers, publishers, and agencies seeking scalable digital marketing solutions. Growth indicators include extensive case studies and a broad range of resources for clients.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and the use of consent management tools to comply with privacy laws. Security best practices such as accessibility features and no visible sensitive data exposure are observed. However, the absence of a dedicated security policy page, incident response contact channels, and vulnerability disclosure mechanisms like security.txt indicates gaps in transparency and readiness. No vulnerable libraries or insecure forms were detected in the HTML content. The site would benefit from publishing explicit security frameworks and incident response procedures to enhance trust and compliance. Overall, the security posture is good but can be improved with formal documentation and communication.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks and practices.
  2. Provide clear incident response contact channels such as security@ or abuse@ emails.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  5. Enhance transparency by providing data protection officer contact information.

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.
