I'm Raimundas, a penetration tester specialising in offensive security. I find, exploit and clearly document vulnerabilities across web apps, external and internal networks, and mobile, combining broad automated coverage with hands-on manual testing. I provide these services to organisations across a range of sectors.

Services.

The vulnerabilities that actually matter, critical-severity issues, business logic flaws, and context-specific risks, most often surface through manual testing: thinking like an attacker and connecting the dots no scanner can. My engagements combine both: broad automated coverage backed by focused, hands-on testing where it counts most, and every engagement concludes with a commercial-grade report: clear findings, risk ratings and remediation guidance your team can act on.

I work independently. You deal directly with me from scoping and testing through to the final report, with no agency or middleman in between.

01

External Perimeter

Assessing internet-facing infrastructure and external network perimeters for exploitable weaknesses, including OSINT sweeps for credentials leaked on the dark web.

02

Internal Network

Simulating an attacker with internal access to uncover privilege escalation and lateral movement paths across services and configs.

03

Web & API

Validating vulnerabilities against the OWASP Testing Guide, from broken authentication to business logic flaws.

04

Mobile

Assessing mobile applications against the OWASP Mobile Top 10, from insecure storage to weak server-side controls.

05

OSINT

Mapping what's publicly discoverable about you, from exposed login credentials to other identifying details, before an attacker does.
