About
KnowBe4 is a cybersecurity company headquartered in Tampa, Florida that operates the world's largest security awareness training and simulated phishing platform, serving over 65,000 organizations across 11 million users. Founded in 2010 by Stu Sjouwerman, the company was built on the thesis that the human element — employees who click phishing links, reuse passwords, and inadvertently install malware — represents the primary attack vector in the majority of successful breaches, and that continuous, measurable security awareness training combined with simulated phishing exercises is the most effective way to reduce this human risk. KnowBe4 went public in 2021 and was taken private by Vista Equity Partners in 2023 in a transaction valued at approximately $4.6 billion.

About
Sysdig is a cloud and container security company founded in 2013 and headquartered in San Francisco, California. The company was created by Loris Degioanni, co-creator of Wireshark, and built around deep runtime visibility into containers, Kubernetes, and cloud infrastructure. Sysdig is the creator and primary contributor to Falco, the CNCF open-source runtime security project that has become the de facto standard for detecting threats in containerized environments based on system call monitoring.\n\nThe company raised $741 million across multiple funding rounds and built a unified CNAPP that combines runtime security with cloud security posture management, vulnerability management, identity risk analysis, and threat intelligence. Sysdig's differentiation comes from its runtime insights layer — by understanding what containers and workloads are actually doing at runtime, it can correlate static scan findings with live activity to identify which vulnerabilities are being actively exploited versus which ones are present but never reached by execution paths. This dramatically reduces the number of CVEs that require immediate remediation.\n\nSysdig's platform is used by enterprises in financial services, healthcare, technology, and government sectors running large-scale Kubernetes environments. The company offers both SaaS and on-premises deployment options to meet data residency and compliance requirements. It integrates with CI/CD pipelines for shift-left scanning, ticketing systems like Jira and ServiceNow, and SIEM platforms. Sysdig's network security capabilities also include Kubernetes network policy recommendations and real-time network threat detection.
