The legal industry is being revolutionized by Harvey, a generative AI platform that automates manual tasks such as contract analysis and due diligence, allowing lawyers to focus on high-value work. To protect sensitive client information, Harvey's security team uses network logs for scalable, efficient threat detection with the help of ClickHouse Cloud. The massive volume of daily log data was challenging to process in real time, but ClickHouse's compression capabilities and query efficiency enabled faster processing. The enriched data provides a clear snapshot of network activity, allowing the security team to detect threats with greater confidence and precision. With this new architecture, Harvey can scale securely, giving peace of mind to internal teams and customers, and stay ahead of evolving threats, ultimately improving the efficiency and productivity of the legal profession.
