White-Box Security
The vulnerabilities hidden in your source — found before attackers read the same code.
Black-box testing finds what is exposed. Source code review finds what is waiting to be exposed. Privout conducts manual, line-by-line analysis of application source code to identify security flaws that scanners miss and penetration tests cannot reach — logic errors, unsafe defaults, cryptographic misuse, and trust assumptions buried deep in business-critical paths.
What We Test
Targeted coverage, not a generic scan.
Authentication & Session Logic
Credential handling, password storage, session lifecycle, token generation, and multi-factor implementation reviewed at the code level for logic flaws and unsafe patterns.
Authorization & Access Control
Role enforcement, privilege checks, object-level authorization, and tenant isolation traced through every code path — not just the ones the UI exposes.
Input Validation & Output Encoding
Every input surface audited for injection, XSS, template injection, path traversal, and deserialization — tracing data from ingress to storage and rendering.
Cryptographic Implementation
Algorithm selection, key management, IV/nonce reuse, padding schemes, and random number generation reviewed against current best practice and known attack classes.
Business Logic & State Management
Race conditions, workflow bypasses, price manipulation, and state transition flaws that emerge only when the full execution path is visible.
Dependency & Configuration Risk
Third-party libraries audited for known vulnerabilities, unsafe defaults, and integration patterns that introduce risk the dependency scanner does not flag.
Methodology
How the engagement runs.
Threat-Informed Scoping
Critical components are prioritized based on threat model, data sensitivity, and attack surface — review effort is concentrated where risk is highest.
Manual Line-by-Line Analysis
Every finding is traced through the actual source — no reliance on automated static analysis output alone. Tools assist discovery; humans confirm exploitability.
Framework & Language-Specific Review
Analysis is adapted to the idioms, security models, and known pitfalls of the specific language and framework — Python, JavaScript, Go, Java, C#, and beyond.
Exploit Proof-of-Concept
Where possible, identified vulnerabilities are validated with a working proof of concept to confirm real-world impact and eliminate theoretical findings.
Deliverables
What you walk away with.
Every engagement closes with clear, actionable output — not a data dump.
Annotated finding report with exact source locations, vulnerable code paths, and severity ratings
Proof-of-concept exploits or detailed reproduction steps for each confirmed vulnerability
Remediation guidance with secure code examples tailored to your language and framework
Complimentary retest to validate applied fixes
Credentials
Backed by hands-on certification.
