Gaetir Reviews for 2026

What is Gaetir?

Gaetir is an AI-powered cybersecurity platform focused on eliminating phishing attacks before they reach user inboxes. Designed for Microsoft 365 environments, Gaetir integrates directly into the customer’s tenant, ensuring no data ever leaves the organization’s control. Its semantic and behavioral AI analyzes every email pre-delivery, detecting linguistic, tonal, and contextual manipulation signals used in social engineering.

Unlike traditional email filters that act after an attack has started, Gaetir proactively blocks threats at the source. The system identifies urgency cues, impersonation attempts, abnormal context, and sender inconsistencies in real time. This approach protects users from AI-generated phishing, credential theft, and 2FA-bypass attacks, without disrupting normal workflow or requiring employee training.

Developed in Sweden, Gaetir combines cybersecurity expertise with advanced AI research to build a “phishing-free future.” The company’s mission is to make social engineering attacks impossible by addressing human-targeted deception through language and behavioral understanding. Its cloud-native, privacy-preserving design aligns with GDPR and NIS2 compliance requirements, making it suitable for modern organizations seeking secure, effortless protection.
