Unexpected outcomes.
Abuse can emerge between steps, across identities, or through an exception. Versarial follows those paths through your running product.
Change the context.
Vary account relationships, locations, verification states, and behavior with controlled synthetic identities.
Take the unexpected path.
Exercise real endpoints and multi-step flows. Explore alternate routes through APIs, app journeys, and agent actions.
Verify what happened.
Compare the intended rule with the resulting state. Capture the evidence, reproduce the finding, and retest the fix.
From discovery to regression coverage
Evidence you
can act on.
Start with an on-demand assessment of a flow or control. Get a report with the path, policy assumptions, and observed outcomes, then turn confirmed findings into repeatable checks.
Use reproduction evidence to verify the fix and preserve the scenario for future runs. Unclear policy expectations stay visible as questions for your team.

Product questions, answered
What to know
before you start.
What is Versarial?
Versarial is a product abuse simulation and control validation platform. It uses controlled synthetic identities and adversarial behavior to pressure test running product flows, uncover business logic gaps, and capture expected versus observed outcomes.
What types of fraud and abuse can Versarial uncover?
Versarial explores account recovery, duplicate accounts, promotion and entitlement abuse, refund and withdrawal logic, geographic restrictions, and AI agent permissions. It can also test overlapping requests and pricing inconsistencies that may create financial loss. Coverage depends on the agreed scenarios and environment.
How does product flow simulation work?
Versarial executes controlled, multi-step scenarios against your app journeys, APIs, or agent actions. It varies identity context and behavior, takes alternate paths, and checks the resulting state against the expected outcome. Findings include reproduction evidence rather than an assumption that a suspicious request succeeded.
What do we need to provide to get started?
Start with access to a sandbox flow and controlled test accounts. Versarial proposes scenarios; your team confirms the important assumptions, permitted actions, and execution limits. Existing policies, PRDs, or designs can add context, but you do not need to write a complete test plan.
What is included in the free assessment?
The free assessment covers one agreed sandbox flow, a bounded set of expert-led scenarios, and an initial outcome summary. Expanded coverage, production testing, and fix retesting are scoped separately. See pricing for ongoing monitoring and release coverage.
Can Versarial discover risks we have not defined rules for?
Yes. Versarial can explore unexpected product paths and surface outcomes your team has not considered. A violation of a confirmed rule is distinguished from an unresolved policy question. For example, duplicate accounts or account sharing may need a business decision before the behavior can be classified as abuse.
Can Versarial help validate controls for a compliance review?
Versarial can test whether confirmed controls hold across specific flows, such as country restrictions across web and API routes. It captures the tested conditions, expected behavior, and observed outcomes for internal risk review or an auditor’s evidence request. The report is evidence of those tests, not a compliance certification.
Can we run assessments before every release?
Retained scenarios can run against candidate builds in staging through GitHub Actions. Your team sets the required checks and release thresholds. Scheduled retesting can also alert you when a previously validated control stops holding, with evidence of the changed outcome.
Does Versarial replace QA or penetration testing?
Versarial complements QA and penetration testing by focusing on how valid product actions can combine into abuse or a business logic failure. It tests whether recovery, exceptions, identity changes, or agent actions enable an unintended outcome. It does not replace all functional testing or infrastructure security assessments.
How is Versarial different from rule backtesting?
Versarial exercises your running endpoints and product flows with controlled scenarios. Rule backtesting evaluates rules against historical data. Versarial observes what the current environment actually allows, including alternate paths and the resulting account or transaction state.
