Verubastion
A managed questionnaire and trust-center workspace for security-sensitive vendors that runs retrieval and drafting inside a customer-controlled isolated environment, links each answer to approved source versions, requires accountable review and exports signed provenance receipts without treating isolation, a signature or an assurance report as proof that an answer is true.
Security and privacy questionnaires force vendors to repeatedly translate policies, controls, audits and architecture into customer-specific answers. Cloud automation can be unacceptable when the questionnaire and source corpus reveal sensitive intellectual property or security posture. The supplied research confirms a direct local private edition at $40 per device monthly, cloud plans at $5–$15 per seat monthly, an enterprise questionnaire product with an analyst-estimated $15,000–$40,000 annual range and another cloud product from $9,600 annually; all are observed market references, not fixed product pricing. It found no confirmed offering combining managed isolated deployment, a customer-approved source corpus, an NDA-gated trust center and per-answer signed provenance receipts. Verubastion distinguishes a physically or logically isolated deployment from a merely private cloud and records the exact network, update, telemetry, backup and support boundary. A source-linked draft is not an attestation, audit conclusion, contract representation or proof that a control operates. Each answer preserves question version, approved evidence, extracted support, limitations, reviewer, approval, export and correction. The signature protects integrity and attribution of a specific receipt; it does not prove semantic truth. Source ingestion, draft, security-owner review, legal or compliance approval, customer delivery, recipient access, acceptance, follow-up and later control change remain separate. The product never answers from expired or unapproved material, silently sends data outside the boundary or labels its own operation compliant merely because a contract or report exists.
A security, trust, compliance or sales-engineering leader at a vendor whose questionnaires and evidence cannot be sent to ordinary cloud automation.
Customers want fast answers from sensitive evidence that they refuse to expose to the automation most likely to accelerate them.
Strong cross-model convergence and a current private-edition competitor support a present test.
One cross-reference and no inbound connections provide limited convergence.
A direct private-edition competitor, clear cloud-only alternatives, one verified interface, a concrete evidence workflow and an unoccupied managed-isolation receipt combination support the wedge.
No inbound connections were supplied, buyer ownership and budget are incomplete, managed isolation is operationally expensive, assurance language is easy to overclaim and no structural incumbent cost is proved.
