Vanta is purpose-built for companies getting their first SOC 2. For organizations running multiple frameworks simultaneously (ISO 27001, SOC 2, NIS2, DORA, GDPR), Vanta's single-framework origins show. The best Vanta alternatives for multi-framework programs include platforms built for continuous compliance across mature, overlapping obligations. Acuna is designed from the ground up for multi-framework control mapping, shared evidence, and audit defensibility at enterprise scale. Drata and OneTrust each address adjacent problems. Choose based on whether your program is scaling compliance depth or adding your first certification.
