Cylance, a California-based cybersecurity startup that taps machine learning and artificial intelligence (AI) to prevent malware, has raised $100 million in a Series D round led by Blackstone Tactical Opportunities and Insight Venture Partners, with participation from existing investors. Cylance claims that 1,000 customers are using its smarts to protect themselves from zero-day attacks and other advanced security infiltrations.

Its platform comprises a suite of algorithm-based security protocols that inspect networks for weaknesses and shuts them down if any are detected. By combining human-generated code with a machine learning approach that predicts whether files are valid or malware, Cylance promises to help companies and governments predict and prevent advanced threats. The company plans to use the funding to support growth by expanding its sales, marketing, and engineering programs.
