Can I get an auto-filled security questionnaire for Slack?+

The questionnaire is mapped to SIG, SOC 2, HIPAA, PCI DSS and 9 other frameworks — answered without sending Slack a single email or waiting for a vendor response.
Is Slack safe to use as a vendor?+
Slack is a communications vendor that handles organizational messages and collaboration data. Safety depends on their current security posture, certification status, and how they handle your specific data. ThirdProof automates this evaluation across 27 intelligence sources — sanctions databases (OFAC, EU, UN), business registration verification, adverse media scanning, and cyber risk assessment — producing a deterministic risk tier with confidence score plus an auto-filled security questionnaire. Run a free investigation to see Slack's full risk profile.
Does Slack have SOC 2 certification?+
Yes — Slack holds SOC 2 + 6 other certs. Rated Moderate Risk — subprocessor list unavailable. See all 5 findings →
Has Slack had any data breaches?+
Data breach history is an important signal for any vendor, particularly communications platforms like Slack that handle organizational messages and collaboration data. ThirdProof's adverse media analysis searches multiple news APIs and public records for data breaches, security incidents, lawsuits, regulatory enforcement actions, and financial distress signals. Each finding is linked to its original source with severity classification.
Is Slack on any sanctions lists?+
Sanctions screening is standard due diligence for communications vendors. ThirdProof screens Slack against OFAC SDN, consolidated international sanctions lists, and PEP databases. The screening uses entity name verification to reduce false positives. If Slack or any associated officers appear on a sanctions list, this triggers automatic escalation to the highest risk tier.
How do I assess Slack for vendor risk?+
Assessing Slack as a communications vendor involves verifying SOC 2, HIPAA BAA availability, and FedRAMP compliance, reviewing their subprocessor chain, and checking sanctions exposure. ThirdProof automates this across 27 intelligence sources in an average of 7 minutes — no questionnaires or vendor participation required. Your first 5 investigations are free.
How long does a ThirdProof assessment take?+
A ThirdProof assessment completes in an average of 7 minutes. 27 intelligence sources are queried in parallel — sanctions databases, business registries, threat intelligence feeds, certificate transparency logs, and more. The result is a deterministic risk tier with confidence score and audit-ready PDF report.
Is ThirdProof free?+
ThirdProof offers 5 free vendor assessments with no credit card required. Each assessment includes the full report — risk tier, confidence score, individual findings, executive summary, and PDF export. Paid plans start at $399/month for teams that need ongoing vendor monitoring.
Can I use a ThirdProof report as SOC 2 audit evidence?+
Yes. ThirdProof reports are designed to satisfy SOC 2 CC9.2 (vendor risk management) requirements. Each report includes SHA-256 integrity verification, methodology disclosure, source attribution for every finding, and AI content labeling. Auditors can independently verify the report's authenticity and trace each finding to its original source.
How is ThirdProof different from a security questionnaire?+
Security questionnaires require vendor participation, take weeks, and produce self-reported answers. ThirdProof queries 27 independent intelligence sources — no vendor involvement needed. Risk tiers are assigned by a deterministic rules engine (not AI opinion), and every finding links to its original source. You get an audit-ready report in an average of 7 minutes instead of waiting weeks for a questionnaire response.
