HP has completed its $1.5bn (£973m) acquisition of ArcSight, and will integrate the company's security portfolio with its own IT operations management software.
ArcSight offers high-end security systems and software for large enterprises, the military and government.
"In a world where perimeter security is no longer enough, businesses need this holistic approach to securing their networks, applications and sensitive data," said ArcSight president and chief executive Tom Reilly when the deal was announced in September.
ArcSight recently released a range of upgrades designed to tackle internal security risks presented by malicious or uneducated internal users, adding to the scope of the new HP security proposition.
HP said that the ArcSight tools will allow enterprise users to apply more context to security incidents and operations, while improving planning and risk management.
Customers could monitor real-time events and activities, assess risk and impact on business operations and respond to and deal with potential and emerging threats, the firm claimed.
HP has made a number of acquisitions his year, including 3Par and Palm.
