Tribble vs Vanta.
Different problems. One workflow.

Vanta's job

Prove you're compliant

Vanta automates evidence collection, continuously monitors your compliance posture, and produces the SOC 2 report, ISO 27001 certification, or HIPAA attestation that says you've passed. It's the authoritative proof of your security program.

Tribble's job

Answer every questionnaire that follows

Having SOC 2 doesn't stop your prospects from sending a 200-question SIG. Having ISO 27001 doesn't stop enterprise buyers from sending a custom security assessment. Tribble drafts every answer from your Vanta evidence, SOC 2 report, policies, and prior submissions -- with source attribution on each one.

What Vanta doesn't replace

Source attribution per questionnaire answer

Vanta's QA product auto-answers questions from a knowledge base and cites sources. Tribble goes further: per-answer confidence scoring tells your team exactly which answers need review, and cross-answer consistency checking catches contradictions across your entire submission before it ships. For the full RFP and DDQ spectrum beyond security reviews, Tribble covers questionnaire types Vanta doesn't.

Why both

Compliance and questionnaire response are different skills

Vanta is built to maintain your security program. Tribble is built to communicate it under deal pressure, on deadline, across formats you didn't control. Most security-conscious teams that close large enterprise deals use both.

"Vanta has Questionnaire Automation. Why do I need Tribble?"

Vanta's QA product is strong for security reviews -- it auto-answers up to 80% of questions from a knowledge base and claims a 95% acceptance rate. Where it stops: Tribble adds per-answer confidence scoring that routes low-confidence items to specific reviewers, and cross-answer consistency checking that catches contradictions across your entire submission. For teams that also handle RFPs, DDQs, and non-security questionnaires, Tribble covers the full response spectrum.

"We share our SOC 2 report directly. That handles most questions."

Your SOC 2 report answers the question "are you certified?" It doesn't answer the 200-question SIG that arrives two days later asking exactly how you implement each control. Tribble drafts those answers from your SOC 2 report and underlying policies -- with every answer linked back to its source.

"We have Drata, not Vanta. Does this still apply?"

Yes. Same dynamic applies to Drata, Secureframe, Sprinto, and any other compliance platform. They produce the evidence. Tribble reads that evidence as source content and drafts questionnaire answers from it. The compliance platform and Tribble are complementary regardless of which GRC tool you use.

"Can Tribble read from our Vanta/Drata documentation?"

Tribble connects to SharePoint, Google Drive, Confluence, Notion, and 40+ other document stores where your compliance evidence lives. If your SOC 2 reports, policies, and certifications are accessible in those systems, Tribble reads them as source content for questionnaire drafting.

Step 1 — Vanta

Achieve and maintain certification

Vanta monitors your controls, collects evidence automatically, and produces your SOC 2 report, ISO 27001 certification, or HIPAA attestation. Your SOC 2 report, policies, and audit evidence live in your document store.

Step 2 — Prospect sends questionnaire

200-question SIG arrives in their format

Your SOC 2 report answers "are you certified?" The SIG asks how you implement each control, what your incident response process is, how you manage vendor risk, and 190 other things. This is where Vanta's job ends and Tribble's begins.

Step 3 — Tribble

Draft sourced answers from your evidence

Tribble reads your SOC 2 report, policies, audit evidence, and prior questionnaire responses. For each question, it drafts an answer and links it to the specific source document. Low-confidence answers route to your security team via Slack.

Step 4 — Submit same day

Same-day turnaround, fully sourced

What previously took your security team 3 days gets submitted the same day. Every answer is traceable. The consistency checker caught contradictions before you submitted. Your prospect gets a professional, sourced response that matches your Vanta evidence.
