Cybersecurity approach

Pentest findings are prioritized by exploitability - not a 200-page PDF nobody reads.

I combine app-level fixes (OWASP) with network and hosting layers.

Backups and restore drills are part of security - ransomware recovery is a backup test.

EU clients: incident logging aligned with GDPR notification timelines.

US clients: prep for investor due diligence and SOC2-minded checklists where relevant.

About me

I'm Viktar Liukevich

Full-stack developer · 15+ years creating web

I am Viktar Liukevich, a developer and security practitioner in Warsaw. I have recovered hacked sites and closed holes in legacy PHP - prevention and layered defense beat emergency cleanup.

Cybersecurity is not only OWASP in code - it is WAF rules, patched servers, monitored logs and a team that knows what to do when alerts fire at 2 a.m.

For formal penetration tests, red-team exercises or compliance-heavy reviews, I work with certified security partners in Poland, Europe and the USA under NDA. I remediate findings in your stack and verify fixes before sign-off.
