Alienvault
Alienvault's Overview
Alienvault was a pioneering cybersecurity company founded in 2007, renowned for its Unified Security Management (USM) platform and the Open Threat Exchange (OTX), one of the largest open threat intelligence communities. Its mission was to make powerful threat detection and response capabilities accessible to organizations of all sizes. Alienvault provided solutions like USM Appliance and USM Anywhere, offering SIEM, asset discovery, vulnerability assessment, intrusion detection, and behavioral monitoring. In August 2018, Alienvault was acquired by AT&T and its technologies and team became a core part of AT&T Cybersecurity, continuing to innovate and protect businesses globally.
Where is Alienvault's Headquarters?
HQ Function
The San Mateo headquarters served as the central command for Alienvault's worldwide operations, housing executive leadership, core engineering and product development, global marketing, sales strategy, and corporate administrative functions.
Notable Features:
The headquarters was situated in a modern office park, likely featuring an open and collaborative workspace design, typical of Silicon Valley tech firms, to encourage innovation and teamwork. Amenities would have catered to a dynamic tech workforce.
Work Culture:
Alienvault fostered a passionate, fast-paced, and innovative work culture. Employees were driven by the mission to democratize cybersecurity. The environment was known for strong collaboration, a customer-centric approach, and roots in the open-source community (OSSIM).
HQ Significance:
The San Mateo HQ was pivotal, marking Alienvault's evolution from a startup to a significant cybersecurity vendor. Its Silicon Valley location provided access to top talent, venture capital, and a vibrant tech ecosystem, fueling its growth and product innovation.
Values Reflected in HQ: The headquarters' design and atmosphere likely reflected Alienvault's core values: innovation in cybersecurity, collaboration (both internally and with the OTX community), and accessibility of its security solutions.
Location:
Before its acquisition, Alienvault had established a global footprint with customers and partners across North America, Europe, Asia-Pacific, and other regions, supported by its international offices. Its Open Threat Exchange (OTX) platform had (and continues to have) a worldwide community of security professionals. Since becoming part of AT&T Cybersecurity, Alienvault's technologies are integrated into AT&T's extensive global network and security operations. This provides global sales, support, threat research via AT&T Alien Labs, and managed security services, ensuring worldwide availability and support for solutions derived from Alienvault technology.
