Cyber Security Pentesting Inc

Cyber Security Pentesting Inc. is a CREST-certified penetration testing consultancy based in Toronto, Canada. Every engagement is principal-led by Arturs Stay, an OSCP, OSEP, and CREST-certified practitioner with 20+ years of enterprise offensive security experience.

We deliver network penetration testing, web application security assessments, cloud security testing (AWS, Azure, GCP), Active Directory attack simulations, red team operations, social engineering testing, AI red teaming, compliance-driven assessments (PCI-DSS, SOC 2, ISO 27001, PIPEDA), and custom tailored penetration tests.

Our clients include enterprises in financial services, healthcare, critical infrastructure, government, and technology sectors across Toronto, Ontario, and all Canadian provinces. Every finding is demonstrated with proof-of-concept exploitation — no theoretical risks, no scanner dumps. Reports are built for two audiences: technical teams get reproduction steps, executives get clear risk narratives.
