Founded in 2000 by Hugh Njemanze and Pravin Kothari, ArcSight is an enterprise software company based in Cupertino, California, that develops security information and event management solutions to help organizations detect, analyze, and mitigate complex cyber threats. The cybersecurity platform serves government agencies and large global corporations, successfully securing over 500 enterprise customers prior to its initial public offering in 2008. After raising over twelve million dollars in venture funding from prominent institutional investors including Kleiner Perkins, the business was acquired by HP in 2010 for over one billion dollars. The software portfolio later became part of Micro Focus through a large spinoff and merger with the Hewlett Packard Enterprise software division during 2017. ArcSight currently operates as a dedicated product line under OpenText following that corporation completing a major acquisition of Micro Focus in early 2023.

ArcSight is a cybersecurity company that developed a sophisticated threat management system designed to collect and analyze large volumes of security data. Its product helps enterprises identify, prioritize, and respond to critical cyber threats while streamlining incident response and compliance activities. ArcSight primarily serves large organizations in sectors vulnerable to cyberattacks, such as retail and financial services, addressing the growing complexity and volume of security data in the networked economy. The company demonstrated strong growth momentum in the 2000s, culminating in a successful IPO in 2008 and a $1.5 billion acquisition by Hewlett-Packard in 2010[1][2].
Kleiner Perkins, the venture capital firm that invested early in ArcSight, is known for backing transformative technology companies. Their mission is to partner with visionary founders to build companies that shape the future across sectors like technology, healthcare, fintech, and AI. Kleiner Perkins emphasizes turning innovative ideas into impactful companies, supporting startups with capital, strategic guidance, and network connections to accelerate growth and market leadership[1][8].
ArcSight was co-founded in May 2000 by Hugh Njemanze, who served as the founding CTO and led product development. The idea emerged from the need to address the exploding rates of cybersecurity incidents and the increasing complexity of security infrastructure in the early 2000s. Robert Shaw, an early investor familiar with Kleiner Perkins, approached the firm to invest in ArcSight, recognizing the potential of its threat management technology. Kleiner Perkins invested in 2002 alongside In-Q-Tel, the CIA’s venture capital arm. The company’s early traction was driven by its best-in-class technology and a strategic focus on large enterprise customers in critical sectors. Kleiner Perkins helped build the board, recruit key executives like CEO Tom Reilly, and facilitated introductions to major clients such as Walmart[1][2][4].
ArcSight rode the wave of increasing cybersecurity threats driven by the rapid expansion of networked digital economies in the early 2000s. As enterprises faced growing vulnerability and complexity in their security environments, ArcSight’s technology addressed a critical market need for actionable intelligence and compliance management. The timing was crucial: cybersecurity was becoming a board-level concern, and regulatory requirements were tightening. ArcSight’s success helped define the SIEM market and influenced how organizations structured their security operations centers. Its acquisition by HP in 2010 underscored the strategic importance of cybersecurity capabilities in the broader tech ecosystem[1][2][3].
ArcSight’s trajectory—from startup to a billion-dollar acquisition—illustrates the critical role of early venture capital support and strategic execution in cybersecurity innovation. For Kleiner Perkins, ArcSight exemplifies their investment philosophy of backing visionary founders to build category-defining companies. Looking forward, cybersecurity remains a dynamic and essential sector, with emerging trends like workload-to-workload identity and API security shaping the next generation of startups, as noted by former Kleiner Perkins investor Ted Schlein. The legacy of ArcSight continues to influence how security analytics evolve, and Kleiner Perkins remains a key player in nurturing cybersecurity innovation[1][5][6].
