APIs are a critical component of modern digital ecosystems, but they also create vulnerabilities that attackers can exploit. Wallarm, a company founded in 2016 to help enterprises prevent and protect against API breaches, faced challenges scaling its infrastructure to deliver real-time threat detection. After migrating from a self-hosted ClickHouse deployment to ClickHouse Cloud, Wallarm was able to overcome latency issues and improve performance, delivering near-instant results and allowing customers to respond to threats without delay. The migration also enabled the company to reduce costs and focus on innovation rather than day-to-day maintenance. With the growing threat landscape driven by AI adoption, Wallarm is well-positioned to tackle today's threats while staying ahead of new risks that come with agentic AI adoption.
