Identity & authorization
Sessions, roles, administrative routes, service identities, and tenant boundaries.
What we challenge
Can a valid account gain authority it should not have?
Cybersecurity engineering
Find what matters.
Close what is reachable.
Security work should lead to a stronger system, not a longer report. We combine adversarial review with the engineering needed to fix the cause and verify the result.
Scope a security reviewSecurity, exercised.
Connected by design.
Protected at every step.
Identity, authority, and data ownership have to agree. The difference becomes visible when the request reaches the boundary.
Tenant isolation
A valid account. The wrong organization.
An administrator changes the requested organization. Their login is valid; the data boundary is not.
RequestPermitted dataStopped / held
Decision record
Awaiting request.
The system will check the request before releasing any sample records.
- Records released
- 0
- Private data
- Untouched
EVENT TRACE0 events
- No request has entered the system.
Illustrative simulation with fictional records. No live systems, accounts, or private data are accessed.
A connected attack surface
Review the system.
Not just the checklist.
Application logic, identity, data, cloud, and autonomous tools interact. So do their failure modes.
Application & APIs
Input handling, state transitions, business logic, webhooks, race conditions, and abuse resistance.
What we challenge
Can ordinary features combine into an unintended action?
Data & privacy
Private files, data movement, exports, retention paths, encryption workflows, and auditability.
What we challenge
Can sensitive information cross its intended boundary?
Cloud & supply chain
Environment separation, credentials, IAM, storage, dependencies, and deployment controls.
What we challenge
Can a small misconfiguration become persistent access?
AI & autonomous systems
Tool authority, retrieval, memory, prompt injection, approvals, evaluation, and evidence.
What we challenge
Can untrusted context become permission to act?
Detection & response
Structured logs, actionable alerts, incident triage, runbooks, and recovery.
What we challenge
Would the team recognize, contain, and reconstruct an incident?
A red-team mindset. An engineering finish.
The finding is
only the beginning.
Understand
Map the assets, sensitive actions, trust boundaries, and business consequences.
Trace
Connect weaknesses into attack paths an adversary could actually reach.
Validate
Confirm behavior with controlled testing. Preserve evidence and reject noise.
Remediate
Fix the root cause, retest the path, and protect the behavior with regression checks.
Leave with an actionable record.
Agreed scope, evidence-backed findings, prioritized remediation, and retest results. Testing stays inside explicitly authorized systems and boundaries.
Include the affected URL, reproduction steps, browser or device context, and potential impact. Do not include passwords, tokens, private keys, or sensitive third-party information.
Do not access or change data that is not yours. Do not perform destructive testing, denial-of-service attacks, social engineering, or credential attacks. Grayston does not currently operate a paid bug bounty program.
Your next move
Bring the concern.
Leave with a path forward.
Start with a critical release, an inherited platform, or a specific finding. We will define the right review boundary.
