Why Ceryvon
A secure-looking workflow can still produce the wrong outcome.
Ceryvon focuses on application-specific logic and authorization failures that often sit outside the reach of generic scanners.
02
Workflow integrity
Skipped approvals, invalid state transitions, repeated actions, and broken cancellation or booking flows.
03
Payments & transactions
Duplicate refunds, inconsistent payment states, replay risks, and credits applied in the wrong state.
04
AI agent permissions
Automated actions beyond intended permissions, sensitive data exposure, and unintended workflow execution.
How it works
A tightly scoped audit, built around evidence.
Define one critical workflow
We agree on a narrow, authorized scope in staging or a dedicated test environment.
Review logic and authorization risk
Ceryvon combines a proprietary analysis engine with expert review. Internal methodology remains confidential.
Separate signals from findings
Potential issues are not presented as confirmed vulnerabilities without sufficient evidence.
Deliver remediation-ready results
Leadership gets a clear risk summary; engineering gets technical context and next steps.
Deliverables
Not just findings. A decision and remediation package.
Every engagement is designed to help both decision-makers and developers move quickly.

Trust by design
Strict authorization, evidence, and confidentiality discipline.
Written authorization
No testing begins without an agreed scope and explicit permission.
Staging-first
A dedicated test environment is preferred wherever possible.
Data minimization
Minimum necessary access, redaction, limited retention, and secure deletion.
Black-box methodology
Ceryvon uses a proprietary analysis engine. Internal detection logic and implementation details are confidential.
FAQ
Clear scope. No exaggerated claims.
Is Ceryvon an automated vulnerability scanner?
No. Ceryvon is an expert-led audit service supported by a proprietary analysis engine.
Does Ceryvon replace a penetration test?
No. It complements traditional testing with deeper focus on business logic, authorization, ownership, and workflow integrity.
Do you test production systems?
The preferred environment is staging or a dedicated authorized test environment. Production is considered only when explicitly authorized and safely scoped.
Can you guarantee that no vulnerabilities remain?
No responsible security service can make that guarantee. Ceryvon clearly communicates scope, confidence, findings, and residual risk.
