Brazilian firms turn to Zero Trust and explainable AI to curb rising cyber risk

Zero Trust, a security model that assumes no user, device or system is trusted by default, has become widely adopted by organizations handling sensitive data. It verifies every access request in real time, enforces least‑privilege access, and continuously monitors activity. In Brazil, weekly cyber‑attack rates rose 38% in 2025, reaching an average of 3,520 attacks per organization, highlighting the need for stronger defenses.

At the same time, explainable artificial intelligence (XAI) is being used to mitigate human‑related risk. While automation increases alert volumes, companies often cannot interpret why a behavior is flagged. A notable deep‑fake fraud in Hong Kong in 2024, where a multinational employee transferred about US$25 million to AI‑generated impostors, underscores the danger. According to the 2026 Verizon Data Breach Investigations Report, roughly 62% of breaches still involve human interaction, making contextual understanding essential. XAI helps security teams identify the true causes of alerts and tailor responses rather than applying blanket measures.
