Certifications

ISO 27001, SOC 2, Cyber Essentials, etc.

Pixis: No published ISO 27001, SOC 2 Type II, or other independent third-party security certifications as of early 2026. GDPR compliance is self-asserted. Absence of independent audits is a significant concern for enterprise procurement teams processing EU personal data.

Regulatory Fit

Suitability for regulated industries and professional services

Pixis: Requires significant due diligence for European deployment. US jurisdiction, absence of published security certifications, and the sensitivity of advertising audience data (which may include special category data proxies) make this a high-risk processor choice for GDPR-regulated organisations.

Ahrefs: Bootstrap model and Singapore jurisdiction are notable differentiators; absence of formal security certifications limits suitability for highly regulated sectors requiring SOC 2 evidence
