F5 has acquired Fletch, a San Francisco-based cybersecurity startup that uses AI to help companies identify threats and reduce alert fatigue. The terms of the deal were not disclosed. F5 will integrate Fletch’s AI capabilities into its Application Delivery and Security Platform (ADSP), which launched in February.
The platform combines F5’s three separate products — BIG-IP, distributed cloud services, and NGINX technology — into a single platform for delivering and securing applications. By adding agentic AI capabilities to our platform, we can provide even deeper insights, real-time threat intelligence, and proactive security recommendations that empower teams to stay ahead of threats,” said Kunal Anand, F5’s Chief Innovation Officer. Fletch’s technology will help F5 accelerate security outcomes across applications, APIs, and infrastructure.
Integrating Fletch’s AI into ADSP
“With F5 ADSP plus agentic AI, we’re not just reacting faster; we’re predicting smarter and protecting better. This is a big leap forward for intelligent, AI-native security,” Anand said.
Fletch was founded in 2020 and had raised $12.5 million in a Series A round led by True Ventures two years ago. The startup has 15 employees, 13 of whom will join F5 as part of the acquisition. By leveraging AI and years of natural language processing know-how, we help organizations translate complex data into clear, human-readable tasks, enabling faster and more intelligent decision-making,” said Kai Wernick, Fletch’s CEO and co-founder.
This acquisition is part of F5’s ongoing efforts to enhance the security features of its platform through advanced AI technology. It marks a significant step in F5’s journey to provide intelligent, AI-driven security solutions to its customers.
