Compliance automation,
honestly compared
How Diligio Compliance compares with the leading ISO 27001 and SOC 2 platforms, on pricing, how evidence gets collected, and where your data lives. We credit where Vanta and Drata lead today.
- Flat $1,999 / year
- Agent proposes, a human certifies
- EU data residency
- One shared knowledge base
All of them, side by side
An honest capability view against the category leaders. Vanta and Drata are more mature on integrations and continuous monitoring today, and we mark exactly where. Details are publicly reported as of June 2026.
Head-to-head comparisons
Vanta is the most mature compliance automation platform, and Drata is known for deep continuous monitoring. Diligio Compliance takes a different route: your own AI agent proposes evidence and control statuses for a human to certify, all on the same knowledge base that answers your security questionnaires. Here is the honest, side-by-side detail.

Four questions separate these tools more than feature lists do, whether you are choosing a questionnaire tool or a compliance platform. New to the processes themselves? Start with the guides.
How the AI prevents mistakes
Single-model drafting puts the burden on a reviewer to catch errors. A second, independent check, whether verifying a questionnaire answer against its source or holding evidence for a human to certify, enforces accuracy before anything is attested.
Whether pricing is published
Most tools in both categories are sold by custom quote with no public rate card and seat- or framework-based scaling. A flat, published price removes both the sales cycle and the per-seat maths.
Where your data is stored
Data residency (for example, EU at rest) is often a fixed requirement for European buyers, and many vendors do not specify a default region publicly.
What is included versus an add-on
SSO, API and agent access, translation, extra frameworks, and implementation are frequently gated behind higher tiers or sold separately. Check the total cost, not the headline.
How we compare
Competitor details are publicly reported as of June 2026. None of these vendors publishes an official rate card, so every price is hedged and dated. We credit each tool's genuine strengths before drawing contrasts, and Diligio's claims map to shipped capability. If you spot anything out of date, email support@diligio.co and we will correct it.
Frequently asked questions
What is the best RFP and DDQ response software in 2026?
The best tool depends on your priority. Responsive (formerly RFPIO) suits large enterprise bid teams; Loopio suits mid-market teams wanting a polished library; AutogenAI suits persuasive long-form bid writing; Arphie and Diligio are modern AI-native options. Diligio focuses on verified accuracy and a flat, published $7,499/year price.
Which RFP tools publish their pricing?
As of June 2026, Responsive, Loopio, AutogenAI, and Arphie are all sold by custom quote without a public rate card. Diligio publishes a flat $7,499 per year that includes the AI, SSO, and API access, so you can compare cost without a sales call.
What should I look for when comparing RFP and questionnaire tools?
Look at how the AI prevents hallucinations (single-model drafting versus independent verification), whether pricing is published and flat or seat-based with add-ons, where your data is stored, whether your content is used to train models, and whether SSO and API access are included or sold as upgrades.
What is the best compliance automation software in 2026?
It depends on your priority. Vanta is the most mature platform with the broadest integrations and framework coverage; Drata is strong on continuous monitoring; Diligio Compliance suits teams that want an AI agent they control with a human-certify gate, one knowledge base shared with their questionnaire answering, and a flat $1,999 per year price.
Is Diligio Compliance a good Vanta or Drata alternative?
For teams that want agent-assisted ISO 27001 and SOC 2 on the same knowledge base that answers their security questionnaires, at a flat $1,999 per year, yes. Vanta and Drata remain more mature on continuous monitoring, integrations, and framework breadth today, which we state plainly on each head-to-head page.
