Asymmetric Security

Asymmetric Security is an AI-native digital forensics and incident response company, founded in 2025 to address the growing gap between the sophistication of modern cyberattacks and the capacity of security operations teams to investigate them. The company operates from offices in London and San Francisco.

Business Email Compromise remains among the most costly categories of cybercrime globally. Traditional digital forensics and incident response engagements are slow and expensive, often requiring 40 or more hours of manual review across thousands of emails and logs for a single investigation. Most security operations centres lack the analytical capacity to investigate the majority of alerts in depth, meaning many attacks go undetected or are reviewed only superficially.

Asymmetric's platform pairs frontier AI models with senior cybersecurity experts drawn from CrowdStrike, Palo Alto Networks, RAND, Stroz Friedberg, Stanford, Oxford, and Cambridge. The system autonomously collects artefacts across email, identity, and cloud applications, reconstructs the attack timeline, generates recommendations, and delivers structured findings to responders — compressing what previously took days into a matter of hours. A distinctive feature is that the company's operational caseload directly informs its AI development, creating a feedback loop that advances both its own capabilities and those of the frontier AI labs it works with.

The company raised £3 million ($4.2 million) in an oversubscribed pre-seed round in January 2026, led by Susa Ventures, with participation from Halcyon Ventures, Overlook Ventures, and angels including Meta's Charlie Songhurst, Entrepreneur First co-founder Matt Clifford, and former Y Combinator president Geoff Ralston.
