The scope is named.
Product, API, cloud surface, mobile app, AI workflow, or infrastructure boundary. A certificate only means something when the reviewed system is explicit.
Trust, earned
Not a badge. A boundary.
A security certificate should not decorate risk. It should mark the moment a reviewed system has no known exploitable findings left in scope.
Clean result, or fixed result. Both are acceptable. Unverified hope is not.
The standard
What has to be true.
Certification starts where marketing stops: with scope, evidence, remediation, and a date that means something.
The review is complete.
We test the real attack surface: access control, data flow, exposed services, business logic, dependency risk, deployment posture, and abuse paths.
The findings are closed.
If no exploitable vulnerabilities are found, the path is clear. If vulnerabilities are found, they must be fixed and verified before certification.
The evidence is preserved.
The certificate is backed by a review record: scope, date, method, severity outcome, remediation state, validity period, and verification notes.
Validity
Twelve months. Unless the system changes first.
Best practice is honest: certification is a point-in-time security statement with a disciplined validity window. We issue it for up to 12 months, or until a material change alters the reviewed surface.
Major releases, new authentication flows, new data classes, new exposed services, infrastructure migration, or critical dependency events trigger re-review. Fast-moving products should add a 90-day checkpoint.

How it moves
From exposed surface to public proof.
Map
We define the system boundary, assets, roles, environments, and buyer-facing trust claims.
Test
We run the security review across code, runtime behavior, interfaces, data movement, and operational assumptions.
Repair
The team fixes what matters. We verify remediation instead of treating a screenshot as proof.
Certify
When the reviewed scope reaches a defensible state, SToFU Systems issues the security certificate.
Coverage
Security has to survive the whole path.
A certificate is strongest when the review follows how the product actually wins, stores data, makes decisions, and exposes trust to customers.
- Web applications and APIs
- Mobile and desktop applications
- Cloud infrastructure and deployment posture
- Authentication, authorization, and tenant boundaries
- Data leakage paths and sensitive workflows
- AI agents, RAG systems, prompts, tools, and memory
- Business logic abuse and payment-impacting flows
- Remediation verification and certificate evidence
Next move
Turn trust into something visible.
Bring the product, platform, or release that needs to be trusted. We will define the scope, test it, close the gaps, and certify the result when it earns it.
