Asymmetric Security, the first full stack AI incident response services company, has raised £3 million in an oversubscribed pre-seed round led by Susa Ventures, along with Halcyon Ventures, Overlook Ventures, and leading angels. Asymmetric's platform pairs frontier AI models with cybersecurity experts to reduce the time and cost of investigations from days to hours. Asymmetric plans to use the funding to hire across its engineering and incident response teams.
Business Email Compromise attacks remain one of the most financially destructive forms of cybercrime, with the FBI’s Internet Crime Complaint Center reporting that 73 percent of all reported cyber incidents were BEC-related, with cumulative losses exceeding $55 billion over the past decade. As AI systems become more sophisticated at mimicking humans at scale, the scale and impact of these attacks are expected to increase.
Asymmetric Security addresses this by combining advanced AI automation with expert human oversight to accelerate forensic investigations, improving speed, accuracy, and cost efficiency. The platform has already accelerated responses for hundreds of attacks, and the company plans to expand its services to include insider threat investigations, ransomware, and nation-state attacks.
Drawing on real-world incidents, Asymmetric builds evaluations and benchmarks to advance its own cyberdefence capabilities and those of frontier AI labs. The team includes cybersecurity and AI experts from CrowdStrike, Palo Alto Networks, RAND, Stroz Friedberg, Stanford University, Oxford University, and Cambridge University, positioning the company to address the growing risks posed by autonomous AI-driven attacks.
