Investigation teams have a love/hate relationship with event logs. The ever-increasing volumes and richness of data opens many possibilities, but also makes day-to-day operations a slog. GPU acceleration is changing basic assumptions around what is possible. From incident response and threat hunting to anti-money-laundering and anti-fraud, Graphistry has been working with F500 and federal teams on more scalable approaches to human-in-the-loop analytics. In particular, we have been bringing end-to-end GPU acceleration to visual graph analytics for visually connecting virtually any log data. Using examples from malware outbreaks to human trafficking, we'll demonstrate what can now be achieved, and dig into the supporting technologies like hypergraphs, Apache Arrow, GoAi, and visual playbooks.
