Vanta is a compliance platform with a DDQ add-on. FillBase is a dedicated DDQ tool that integrates with Vanta. They complement each other.
TL;DR: Vanta's DDQ feature is fine for 1–2 simple questionnaires per month. For 3+ DDQs, complex formats, or questions beyond compliance controls, add FillBase.

FillBase integrates with Vanta — it pulls your compliance data as one of many knowledge sources. Vanta handles continuous compliance monitoring; FillBase handles DDQ completion. Most teams keep both.
Vanta knows your SOC 2 controls. It doesn't know the nuanced DDQ answer your CTO wrote at 11pm, the architecture diagram in Google Drive, or the pentest report from last quarter. FillBase ingests everything — compliance data, past DDQs, internal docs — and builds a compound knowledge base.
Vanta for compliance monitoring (SOC 2 readiness, continuous monitoring). FillBase for DDQ completion. They integrate — FillBase pulls your Vanta data automatically.
No. FillBase doesn't do compliance monitoring, evidence collection, or SOC 2 audit prep. It's a DDQ completion tool, not a GRC platform.
Yes, it's included in your Vanta subscription. If it covers your needs (1–2 simple DDQs/month), there's no reason to add another tool.
