History
CloudLock was founded in 2011 in the United States by Gil Zimmermann and Ron Zalkind. It developed in the context of a major change in enterprise computing: organizations were moving business processes, collaboration, and data storage to cloud applications while traditional security architectures remained centered on corporate networks and on-premises infrastructure. The company's business was built around cloud security and, more specifically, the cloud access security broker category. CASB providers seek to give organizations visibility and control over the use of cloud services. Typical objectives include identifying applications in use, monitoring user and administrator activity, applying access policies, protecting sensitive information, and helping customers address regulatory or internal compliance requirements. CloudLock's positioning therefore connected security operations with data governance: it was not simply a provider of network connectivity, but a specialist intended to help enterprises understand and control how information moved through cloud platforms. Its principal offering is identified in the available material as CloudLock CASB. The product's historical role was to support enterprise protection of data in cloud applications. The supplied sources do not provide a complete chronology of product releases, named editions, technical architecture, customer list, or measurable commercial results, so those aspects cannot be reconstructed reliably here. In 2016, Cisco agreed to acquire CloudLock. Cisco had built a substantial technology portfolio through acquisitions, and its acquisition strategy included companies related to networking, software, and security. CloudLock fit that strategy by adding cloud-focused security capabilities to Cisco's broader portfolio. The transaction was significant for CloudLock because it changed the company from an independent specialist into an organization operating within Cisco's cloud security business. After the acquisition, CloudLock was no longer described in the supplied material as an independent listed company. Cisco became its parent and owner. The available references do not establish the exact post-acquisition corporate structure, whether all products continued under the CloudLock name, or the date on which any standalone operations were discontinued. They also do not provide acquisition consideration, revenue, employee numbers, subsequent executive appointments, or a detailed record of marketing programs and disputes. Historically, CloudLock represents the emergence of cloud security as a distinct enterprise technology segment. Its core contribution was to address the governance and protection problems created when business data and workflows moved into externally hosted applications. Cisco's acquisition reflected the strategic value that large networking and security vendors placed on CASB and cloud data protection capabilities during the expansion of enterprise cloud adoption.
