Engagements
Penetration testing from TSR White Hat
Simulate real attacks on applications, networks, and mobile apps before someone else does. Methods align to OWASP, NIST 800-115, and related standards. Deliverables: risk-rated findings, proof context, and remediation guidance your team can act on.
Network penetration testing
External and internal testing against real network attack paths.
- External and internal network testing
- Perimeter and access-control evaluation
- PTES / MITRE ATT&CK-aligned simulation
- Wireless assessment when in scope
Mobile penetration testing
Security testing for iOS and Android apps, plus the APIs and backends they talk to.
- iOS and Android application testing
- API and client-server communication security
- Mobile backend and on-device data storage review
- Risk-rated findings with remediation guidance
Vulnerability scanning
Surface gaps on a cadence. Scanning finds candidates; testing proves exploitability.
- Scheduled or project scanning
- Feeds a remediation plan
- Supports compliance evidence and hygiene
- Positioned beside pen test, not as a replacement
