ArcSight, Inc. was a United States-based software firm focused on delivering security management and compliance solutions tailored for corporate enterprises and governmental organizations. Following its acquisition by Hewlett-Packard (HP) in 2010, ArcSight was integrated into Hewlett Packard Enterprise after HP's corporate division, and subsequently transferred to Micro Focus. In 2023, OpenText completed the purchase of Micro Focus, thereby acquiring ArcSight as part of the transaction.
ArcSight by OpenText represents a cybersecurity offering introduced in 2000 that provides advanced big data analytics and intelligence tools for security information and event management (SIEM) alongside log management. This product assists businesses in detecting and prioritizing security threats, orchestrating incident response efforts, and optimizing audit and regulatory compliance workflows.
History
Established in May 2000 in Cupertino, California, ArcSight was co-founded by CEO Alex Daly and CTO Hugh Njemanze, with Pravin Kothari serving as Vice President of Engineering and Pat Figley as Director of Sales. Originally launched under the name Wahoo Technologies, the company pivoted from developing a caching platform to focusing on security event analysis after recognizing a market need for managing large volumes of data. The organization adopted the name ArcSight in January 2001.
In July 2001, Robert Shaw took over from Daly as CEO. ArcSight submitted its initial public offering paperwork on September 11, 2007, and officially listed on Nasdaq under the ticker ARST on February 14, 2008. Notably, it was the sole Silicon Valley enterprise to go public during the economic downturn of 2008. Leadership transitioned to Tom Reilly in 2008 when he replaced Shaw as CEO.
HP announced its intention to acquire ArcSight in September 2010 for roughly $1.5 billion, completing the transaction the following month when ArcSight had a customer base exceeding one thousand clients. This acquisition broadened HP’s cybersecurity offerings by incorporating ArcSight’s Logger, Enterprise Security Manager (ESM) technology, and IdentityView solutions.
On September 7, 2016, Hewlett Packard Enterprise revealed plans to divest its software division—including ArcSight—through a merger with Micro Focus. Micro Focus aimed to significantly enhance profitability margins on these established infrastructure products within three years. The merger concluded successfully on September 1, 2017.
By January 2019, ArcSight’s product lineup included ESM version 7.0, Express version 5.0, Investigate version 2.20, and Data Platform version 2.31—integrating components such as Logger, ArcMC, and Event Broker. On February 14, 2019, Micro Focus expanded its cybersecurity analytics capabilities within the ArcSight portfolio by acquiring Interset.
