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.

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

PubMatic operates in the digital advertising technology sector, focusing on programmatic advertising solutions for publishers and buyers. Its business model revolves around providing a supply-side platform (SSP) and complementary products that enhance monetization and campaign efficiency. The company targets large enterprises and media companies globally, supported by a strong brand and extensive case studies showcasing client success. PubMatic's partnerships and memberships with industry bodies like IAB and DCN reinforce its market credibility. The presence of investor relations and career pages indicates a mature corporate structure and growth orientation. Revenue streams likely include platform fees, technology licensing, and value-added services such as identity management and commerce media solutions. The company’s global infrastructure and data processing capabilities position it competitively in the ad tech ecosystem.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no exposed sensitive information in the HTML content. Cookie consent is actively managed via Evidon, supporting privacy compliance. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not visibly present, representing an area for improvement. No security policy or incident response contact information is published, which could enhance transparency and readiness. The absence of a security.txt file or vulnerability disclosure program limits external security engagement. Overall, the site follows good security practices but could benefit from enhanced header policies and published security governance documentation.

Recommendations

  1. Implement and verify Content-Security-Policy header to mitigate XSS and data injection risks.
  2. Add X-Frame-Options and X-Content-Type-Options headers to protect against clickjacking and MIME sniffing.
  3. Publish a dedicated security policy page including incident response contacts to improve transparency.
  4. Create and host a security.txt file to facilitate responsible vulnerability disclosure.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.

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.
