Asymmetric Security announced its public launch on May 29, 2026, alongside a $4.2 million pre-seed round led by Susa Ventures. The company is building AI-native digital forensics and incident response (DFIR): tools intended to help security teams gather and analyze evidence during cyberattacks, with human responders involved in decisions.
What is Asymmetric Security?
Asymmetric Security is a company focused on AI-native digital forensics and incident response. DFIR teams investigate security incidents by assembling evidence, understanding what happened, and helping organizations decide how to respond. The founders describe automated digital forensics as a future capability that will become widespread; that is the company’s prediction, not an independently established outcome. Asymmetric’s company page
SecurityWeek reported that the platform collects forensic artifacts from email, identity, and cloud applications, analyzes them to understand an attack, and presents findings to human responders. In that account, people handle edge cases and risk decisions. This describes the reported workflow; it does not establish independently tested performance or superiority over other incident-response approaches. SecurityWeek’s report

How much did Asymmetric Security raise, and who invested?

It did not disclose individual investment amounts. The founders’ launch and funding announcement

Who founded the company?
The May 29 announcement identifies Alexis Carlier, Zainab Ali Majid, and Pippa Thompson as Asymmetric’s founders and the post’s authors. SecurityWeek reported that the company was founded in 2025 and had offices in London and San Francisco; those details are attributed to that outlet rather than confirmed in the surfaced company announcement. SecurityWeek’s report
What experience and goals does Asymmetric describe?
The founders say they have responded to hundreds of cyberattacks using AI systems they developed internally. That “hundreds” figure is the founders’ account and has not been independently audited in the sources cited here. They also say they want to use incident-response experience to create realistic training scenarios and evaluations, with the goal of improving their own cyberdefense AI and that of frontier AI labs. These are company-reported experience and intentions, not measured product outcomes. The founders’ announcement
What is known—and not yet established—about the product?
The available reporting gives a high-level picture of evidence collection across email, identity, and cloud applications, followed by analysis and human review. It does not establish current pricing, service-level terms, specific integrations, deployment options, customer names, commercial availability, or independently validated performance. Asymmetric’s newsroom later listed posts dated July 31, 2026, about its agentic DFIR work being featured in a Google DeepMind agent security paper, and August 7, 2026, about supply-chain attacks. Those listings show later public activity, not customer adoption or demonstrated efficacy. Asymmetric’s newsroom
Why do reports give different dates for the stealth exit?
SecurityWeek published a report titled “Asymmetric Security Emerges From Stealth With $4.2 Million in Funding” on January 21, 2026. The company’s own launch post is dated May 29, 2026, and identifies that date as its public launch. These dates conflict; the official post is the primary source for the company’s stated launch date, while SecurityWeek’s earlier report should be understood as its own publication chronology rather than merged with the company’s date.
