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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

DoubleVerify operates in the media and technology sectors, targeting advertisers, brands, agencies, marketplaces, and publishers. Their business model revolves around providing verification and optimization services that improve digital advertising effectiveness and reduce waste. The company leverages AI technologies such as DV Scibids AI for real-time campaign optimization and DV Rockerbox for outcome measurement, indicating a strong innovation focus. Their market position is that of a trusted leader with a global footprint, supported by investor relations and trust center resources. The company’s ecosystem includes partnerships and integrations with major platforms and marketplaces. Growth indicators include active content updates, webinars, and thought leadership. The website’s comprehensive service offerings and transparent corporate information reflect a mature and credible business operation.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and domain registration protections such as clientTransferProhibited status. Use of Google Tag Manager and TrustArc indicates attention to privacy and consent management. However, DNSSEC is not enabled, which could be improved to prevent DNS spoofing. No explicit security.txt or incident response contacts were found, which is a gap in vulnerability disclosure readiness. The site uses validated contact forms and does not expose sensitive data in the HTML. Security headers are likely present but not fully confirmed. Overall, the security maturity is good but could benefit from additional hardening and transparency measures to align with best practices and compliance frameworks.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing attacks.
  2. Publish a security.txt file to provide clear vulnerability disclosure and incident response contacts.
  3. Add or verify Content-Security-Policy and other security headers to mitigate cross-site scripting and related attacks.
  4. Explicitly document incident response and abuse contact channels to improve transparency and trust.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are in use.

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.
