About Pentesterra

Built by Security Researchers.Trusted by Security Teams.

Pentesterra was founded in 2021 in Italy with a single goal: make automated offensive security as thorough as a skilled red team - without the cost and overhead. We built an end-to-end platform that discovers, verifies, and chains real exploits across your entire attack surface, deployable in SaaS or fully air-gapped on-prem environments.

Serial entrepreneur and cybersecurity expert with over two decades of experience in R&D, cybersecurity, Big Data, AI, and Deep Learning. Olesia has founded multiple technology ventures and achieved successful exits across security and data intelligence.

She built Pentesterra from the ground up - from the triage pipeline and distributed scanner architecture to the KB exploit verification engine and the Attack Chain Analysis that maps code, network, and web findings into red-team-grade kill chains.

Olesia is a frequent speaker and author of hundreds of publications on information security, data intelligence, and emerging cyber threats. She brings both the technical depth and the product vision that make Pentesterra different from conventional scanners.
