London-based cybersecurity startup Infrawatch has raised $3 million in a pre-seed funding round announced on 20 May 2026, as investors back its effort to build what it describes as an Internet Infrastructure Intelligence Layer.

The round was co-led by Outward VC and TriplePoint Ventures, with participation from Portfolio Ventures and fintech and cyber angel investors.

Infrawatch is developing a platform designed to help organisations detect and classify attacker infrastructure in real time, with the aim of stopping cyberattacks, fraud, scams and online abuse before they happen. The company says the funding will be used to grow its engineering and research teams, accelerate platform development ahead of a general launch later this year, support early enterprise deployments, and expand into the US.

The raise points to continued investor interest in cybersecurity tools focused on earlier threat detection, particularly as companies look for ways to identify malicious activity before it reaches customers, users or internal systems.
