The recent F5 RIF was needed to pay for these acquisitions this year
F5 Networks has made several acquisitions in 2025 to expand its cybersecurity and AI capabilities. The recent constantly changing strategy has focused on integrating AI-native security and cloud-native observability into its Application Delivery and Security Platform (ADSP).
CalypsoAI: Acquired in September 2025 for $180 million, this Dublin-based firm adds real-time threat defense and AI guardrails for securing generative and agentic AI applications.
MantisNet: Acquired in August 2025, MantisNet specializes in real-time network observability using eBPF technology to provide visibility into encrypted traffic in cloud-native environments.
Fletch: This San Francisco-based cybersecurity startup, acquired in June 2025, uses agentic AI to analyze threat intelligence for prioritizing and remediating security threats.
LeakSignal: Acquired in March 2025, LeakSignal focuses on real-time data protection for AI applications.
F5 doesn't have the talent nor brains to do any of these things by itself. All must be bought.
