FirstSight by SafeGuard Cyber is a next-generation cybersecurity platform powered by contextual AI. It empowers security teams to investigate and remediate unmonitored communications in minutes. FirstSight analyzes language and behavior across communication channels to alert security teams to high-frequency and costly attacks such as credential theft, impersonation, phishing, malware, policy violations, and insider threats across the expanding communication attack surface. The platform is built on an ontological architecture utilizing large language models (LLMs), behavioral analysis, social knowledge graphs, and generative AI. FirstSight incorporates domain-specific knowledge about the customer's enterprise, enabling a deeper understanding of the relationships between threats, vulnerabilities, and countermeasures. This allows customers to react more quickly and effectively to threats.
