Independent penetration testing — web, mobile, API, and network. Every engagement is manual, human-driven, and delivered outside your business hours so your operations are never disrupted.
Engagements can be delivered at any time — including outside business hours and on weekends. Your team stays focused, systems stay stable, and disruption risk drops to near zero.
About
Vantage Offensive Security is an independent security firm specialising in offensive security engagements — web applications, mobile, API, network, and Active Directory environments.
Every engagement is delivered manually. No automated scanning, no templated reports, no noise. Testing is scoped precisely, executed with full focus, and documented so your team can act on findings immediately.
Beyond client work, we conduct independent vulnerability research — resulting in 6 publicly disclosed CVEs and security contributions acknowledged by Oracle, Nokia, Informatica, and SonicWall.
