Computer and Network Security London, London 11–50 employees Founded 2017 Privately Held

Keepnet builds a human risk management platform combining phishing simulations, adaptive training, and threat response tooling. The stack (Azure, AWS, .NET, Kubernetes, Vue) and active projects show a shift toward agentic AI and real-time API automation—but the pain-point list flags scaling challenges with agentic systems and operational complexity. Hiring (engineering-led, with a new Head of Engineering) is accelerating, pointing to infrastructure and backend maturity work ahead of sales expansion.

About Keepnet

Keepnet is a London-based cybersecurity startup founded in 2017 that addresses human-driven security risk through a consolidated platform. The product surfaces three main capabilities: phishing simulations to test employee awareness, adaptive training to reduce susceptibility to social engineering, and phishing response workflows to accelerate threat detection and remediation. The company targets mid-market enterprises where security teams struggle with alert velocity and breach attribution. Keepnet operates as a SaaS product on Azure and AWS infrastructure, with a backend architecture built in .NET and Kubernetes. Current hiring reflects a dual focus: backend and platform engineering (scaling SaaS infrastructure and agentic AI) alongside a single sales hire (UK direct expansion).
