Offensive security focused on what keeps the business running

Matteo Nava is the founder and CEO of Berghem, a company he built from the ground up into a reference in ethical hacking and offensive security, serving major banks and financial institutions in Brazil and abroad. At the head of the operation, he sets the strategic vision, the technical posture and the quality standard of the firm.

With deep experience in red team, pentest and adversarial simulation, he leads a team dedicated to raising the defensive maturity of organizations in regulated, high-criticality environments — combining technical rigor, business judgment and a commitment to measurable results.

Gislaine leads Berghem's talent management strategy, organizational development and the strengthening of a culture of continuous learning, in a market highly competitive for professionals specialized in offensive security.

Beyond her work in people management, she is also responsible for overseeing projects for large enterprises, connecting business needs to human development and delivery excellence.

Raphael Schneider oversees pentest operations, Red Team exercises and security assessments for Berghem's enterprise clients. He is the central point of technical coordination, ensuring every engagement is run under the firm's proprietary methodology, with analytical depth and adherence to international industry standards.

Responsible for methodological consistency, on-time delivery and quality across all projects, he leads the articulation between the offensive teams and the client relationship, sustaining the level of technical excellence that defines Berghem's reputation in critical, regulated environments.

Lorenzo Nava leads Berghem's AI security practice and drives the development of Berghem Agents, the company's agentic EHT capability. His work combines applied research and offensive engineering, positioning the firm at the frontier between artificial intelligence and offensive security.

He is also responsible for the group's European operations, at the head of Berilo S.r.l., extending Berghem's methodology and quality standard to the international market from Bergamo, Italy.
