Discuss your applications and infrastructure.
Share the applications, infrastructure, and test environments you want included.
What we review
Test the path an attacker would actually take.
Web, mobile, API & backend
Authentication, sessions, authorization, business logic, data exposure, and integration boundaries.
External, cloud & infrastructure
Internet-facing services, cloud control planes, secrets, CI/CD, storage, and remote access.
Internal, network & identity
Segmentation, privileged access, lateral movement, internal services, and trust relationships.
Timing
When to test
Before launch
Test exposed services and critical workflows before launch.
After change
After a major cloud, identity, network, or architecture change.
Before external review
A customer, insurer, or auditor needs evidence of security testing.
After an incident or concern
After an incident, acquisition, or concern about an exposed path.
Our approach
How we test your systems.
Set the scope and build the threat model
Agree targets, testing windows, exclusions, and stop conditions. Map the actors, entry points, and trust boundaries in the tested environment.
Trace and test attack paths
Test how an attacker could gain access, escalate privileges, and reach sensitive data or actions. Record which security properties hold and where controls fail.
Capture evidence and reproductions
Validate findings within the agreed rules. Document preconditions, reproduction steps, and remediation so your engineers can investigate and rerun the tests.
Retest fixes and document conclusions
We always verify fixes through retesting and record their status. Tie the principal’s signed opinion to the tested environment, scope, and evidence.
What you receive
What your team receives.
Findings report
Validated findings with evidence, attack preconditions, and remediation guidance.
Threat model
Actors, trust boundaries, and attack scenarios, including those blocked by existing controls.
Record of flows and security properties tested
How an attacker could enter, escalate, move, and reach a sensitive outcome, and which properties along that path held.
Invariant register
The security properties tested, the results, and supporting evidence.
Evidence and reproductions
The paths we proved, in a form your engineers can rerun.
Signed opinion on the reviewed baseline
The principal’s conclusions, tied to the tested environment, scope, and evidence.

FAQ
Frequently asked questions
Can you test production systems?
Yes, when rules, access, timing, data handling, and stop conditions make the risk acceptable. Some cases may move to staging.
What access and test accounts do you need?
We agree the targets and access during scoping. Testing authenticated workflows needs representative accounts for the roles in scope, plus details of expected permissions and business rules. Infrastructure testing may require network or environment access. If the engagement includes code review, we also need access to the code during scoping.
Do you use automated scanners?
Tools support discovery and coverage, but the engagement is manual, architecture-aware testing and validation.
Can you test authenticated roles and business logic?
Yes. Representative accounts, roles, workflows, and expected behavior let us evaluate authorization and business-critical paths.
Do you retest findings?
Yes. We always provide remediation guidance and verify fixes through retesting. The proposal defines the retest window and access requirements, and the final report records the results.
What determines the price and duration?
The number of applications, user roles, environments, and workflows affects the effort, along with the depth of testing. We define the testing window, access requirements, and retest scope in the proposal.
