AI cybersecurity startup Darktrace scores $75m, now valued at $850m

Machine-learning enterprise-focused cybersec firm Darktrace has raised $75m in order to expand its sales operations into Latin America and Asia as it prepares for a possible IPO. The $75m Series D fundraising round, led by new investor Insight Ventures, comes a year after a $65m funding round and propels the company towards tech unicorn status (startups valued at over $1bn). Analysts value Darktrace at $850m. Existing investors Summit Partners, KKR and TenEleven Ventures also contributed to the latest funding round. Cambridge-based Darktrace, backed by one-time Autonomy chief exec Mike Lynch, uses machine learning and AI technology to protect corporate networks against cyber threats through what it markets as an "Enterprise Immune System".
