A / 01
Investigate context
Keep actors, sessions, object ownership, and application state in view instead of treating every request as an isolated payload.
APPLICATION SECURITY · PRIVATE BETA
Find the flaws
that hide in behavior.
Modern applications break in the gaps between users, permissions, state, and business rules. VulnGPT is built to investigate those gaps — and demand evidence before raising an alert.
For applications you own or are authorized to test.

EVIDENCE-FIRST ENGINEERING
BUILT FOR THE HARDER QUESTIONS
Who can access this?What changes across roles?Can the behavior be reproduced?
01 / THE EXPERIENCE
Designed for clarity.
Built for scrutiny.
VulnGPT is being developed for both hands-on security practitioners and builders who need a clearer path to application security.
Genuine product-interface captures supplied for this showcase. Open any image for the full-size view. Workspace names, counts, statuses, and report controls reflect the captured state only; they are not live telemetry, customer outcomes, or a guarantee of current availability. The report capture explicitly shows generation and download disabled by export policy.
02 / THE APPROACH
A response is a clue.
Not proof.
Finding a suspicious response is easy. Establishing what it means — under the right identity, state, and permissions — is the hard part.
A / 02
Challenge the hypothesis
Separate discovery from confirmation. Look for controlled evidence that supports — or falsifies — a suspected issue.
A / 03
Make results actionable
Prioritize reproducible evidence and clear reasoning, so security teams spend less time triaging unsupported signals.
03 / WHAT WE INVESTIGATE
Beyond the payload.
Complex application vulnerabilities emerge from relationships and transitions — not just strings that match a known pattern.
Authorization boundaries
Investigate object-level access, ownership checks, and BOLA/IDOR-style failures across actors.
Object accessRole boundaries
Authenticated workflows
Reason across sessions, identity, and multi-step flows where one request depends on what happened before.
Session continuityState transitions
Business logic
Probe the assumptions connecting actions, records, roles, and workflow rules — where generic scans often stop short.
Workflow integrityInvariant testing
Interference-aware validation
Account for WAF behavior, throttling, session expiry, and changing state before interpreting a result.
Signal qualityRetesting
04 / THE WORKFLOW
From uncertainty
to evidence.
A disciplined path from a behavioral signal to a finding a human can inspect and reproduce.
OBSERVE
Build context
Understand the reachable application behavior, identity, and relevant state.
HYPOTHESIZE
Identify an invariant
Form a testable hypothesis about what the application should enforce.
FALSIFY
Test the boundary
Use controlled interventions to distinguish a real flaw from a misleading signal.
PROVE & RETEST
Preserve the evidence
Keep findings tied to observable behavior and a path that can be checked again.
05 / VALIDATION PRINCIPLE
Evidence before conclusions.
A security result should explain the expected boundary, the controlled test, the observed behavior, and the limitations. A suspicious signal is a reason to investigate—not a performance claim.
VulnGPT is in private beta. No public detection-rate, universal zero-false-positive, or independent-certification claim is made here.
