DoubleVerify is a leading enterprise technology company specializing in digital media verification, optimization, and measurement services for brands, agencies, marketplaces, and publishers worldwide. Founded in 2007, the company has established a strong market position by providing comprehensive solutions to ensure media quality, fraud detection, brand safety, and campaign performance. Their DV Media AdVantage Platform integrates verification, AI-powered optimization, and outcome measurement to deliver measurable business results across multiple channels and formats. Technically, the website is built on a modern WordPress CMS with robust SEO and accessibility features, leveraging Google Tag Manager and Jetpack for analytics and performance. Hosting is provided via Akamai, ensuring fast and reliable content delivery. The site is mobile-optimized with rich multimedia content including SVG graphics and embedded videos, reflecting a mature digital infrastructure. From a security perspective, the site enforces HTTPS with a strong SSL configuration and domain transfer protections. While DNSSEC is not enabled, other best practices such as clientTransferProhibited status and secure form handling are observed. Privacy compliance is well addressed with clear privacy and cookie policies, consent mechanisms, and GDPR indicators. However, incident response and vulnerability disclosure policies are not explicitly found. Overall, DoubleVerify presents a low-risk profile with high business credibility, professional digital presence, and solid security posture. Strategic recommendations include enabling DNSSEC, publishing incident response and vulnerability disclosure policies, and enhancing security headers to further strengthen trust and compliance.

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 digital advertising technology sector, targeting large brands, agencies, marketplaces, and publishers. Their business model centers on providing SaaS-based media verification and performance optimization solutions, leveraging AI and data analytics. The company maintains a strong partnership ecosystem, including investor relations and customer portals, supporting enterprise clients globally. Growth indicators include recent reports on AI and automation in advertising, thought leadership content, and active event participation. The company’s market position is reinforced by comprehensive service offerings and a focus on transparency, efficiency, and accountability in digital advertising.

Security posture

The security maturity level of DoubleVerify’s website is good, with HTTPS enforced and domain transfer protections in place. The absence of DNSSEC is a minor gap. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Security best practices such as secure form handling and use of reputable third-party services are evident. However, the lack of publicly available incident response and vulnerability disclosure policies limits transparency in security readiness. Compliance with GDPR and cookie consent mechanisms is well implemented, reflecting a strong privacy culture. Overall, the security posture supports business continuity and client trust but can be improved by publishing formal security policies and enabling DNSSEC.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a clear incident response policy and contact channels for security issues.
  3. Create and host a security.txt file to facilitate vulnerability disclosures.
  4. Implement and enforce Content-Security-Policy headers to mitigate XSS risks.
  5. Regularly audit and update third-party scripts and plugins to avoid vulnerabilities.

Notes

The website is built on WordPress 6.8.3 with Yoast SEO and Jetpack plugins, indicating a modern and maintainable CMS infrastructure. Use of Google Tag Manager and asynchronous script loading optimizes performance and analytics. Hosting via Akamai nameservers suggests a CDN-backed delivery for fast global access. The site is mobile responsive with good accessibility features, including screen reader support and keyboard navigation aids. SEO is well addressed with meta tags, Open Graph, and JSON-LD structured data. No major technical debt or deprecated technologies were detected. Opportunities exist to enhance security headers and enable DNSSEC for improved resilience.
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.
