Whistic
AI-assisted third-party risk management platform that lets vendors publish standardized security profiles once and reuse them across buyer assessments.

Whistic runs a two-sided third-party risk management (TPRM) platform: vendors build a standing security profile once (SOC 2 reports, SIG questionnaire responses, pen test summaries, certifications) and publish it to a shared catalog, so enterprise buyers can pull existing answers instead of sending a fresh spreadsheet every time. The pitch is fewer duplicate questionnaire cycles on both sides of a vendor relationship, which is the actual bottleneck in most TPRM programs rather than a lack of assessment templates.
Founded in 2015 and headquartered in Pleasant Grove, Utah, Whistic has layered AI features onto that base workflow — Assessment Copilot summarizes SOC 2 reports and cross-checks vendor documentation against questionnaire answers, and Smart Search lets a reviewer query a vendor’s existing document set in natural language instead of waiting on a new response cycle. It supports the Shared Assessments SIG questionnaire and integrates with GRC tooling used downstream of the vendor review.
Whistic has raised $71M total, including a $35M Series B in 2022, and competes with SecurityScorecard, OneTrust Vendorpedia, and Vanta’s vendor risk module in a TPRM market that is consolidating around platforms bundling ratings, questionnaires, and continuous monitoring together.
Innovation Matrix Assessment
Shipped AI-assisted Assessment Copilot and Smart Search features on top of its core profile-exchange workflow, showing steady product investment beyond the original questionnaire-catalog model.
Mature SaaS platform with SIG questionnaire support and integrations into downstream GRC tools; publicly reported ARR in the low eight figures suggests a functioning, revenue-generating operation rather than an early-stage experiment.
Raised a $35M Series B in 2022 (total $71M) and reports reviewer turnaround improvements (customers citing 80% of requests closed within a day), though no funding has been reported since and headcount has stayed roughly flat.
The publish-once, reuse-everywhere profile model is a real improvement over one-off vendor questionnaires, but the underlying idea (shared security profile catalogs) is now common across several TPRM vendors rather than unique to Whistic.
No independent third-party benchmark of assessment accuracy was found; efficacy rests on customer-reported time savings and CIS Center for Internet Security case-study material rather than an outside audit.
Third-party risk exposure is a persistent audit and board-reporting requirement across regulated industries, keeping demand for a shared vendor-assessment exchange steady regardless of the broader security budget cycle.
Why CISOs Should Care
Cuts the security team's questionnaire-review backlog by letting vendors reuse a standing, evidence-backed profile instead of re-answering the same SIG questions for every customer.
What Makes It Different
Built the vendor-side publish-once catalog first, rather than starting from the buyer-side ratings score that competitors like SecurityScorecard lead with.
The Matrix Verdict
62/100 — INCREMENTAL INNOVATOR
A solid, focused TPRM workflow tool with genuine efficiency gains for questionnaire-heavy vendor programs, but it operates in an increasingly crowded category where ratings platforms are adding the same profile-exchange features.
Editorial Note: Claims vs. Verified Findings
The 80%-of-requests-in-a-day figure and other turnaround statistics are customer-reported and Whistic-published; independently verifiable facts are limited to the funding history (Crunchbase/PitchBook) and the CIS Center for Internet Security case study confirming platform use.
