Enclave is a network security company that provides a software-defined networking platform designed to simplify the creation and management of secure private networks. The platform enables organizations to connect computers, servers, cloud instances, and containers across disparate infrastructure without relying on traditional VPNs or complex access control lists (ACLs). Enclave's core offering centers on a zero-trust network access (ZTNA) model, allowing organizations to establish private, encrypted connectivity between endpoints while minimizing exposure to discovery and attack. The platform is designed to work on top of existing network infrastructure, requiring minimal changes to network configurations. The product targets a broad range of technical and organizational roles, including system administrators, DevOps practitioners, developers, systems architects, and CISOs. It also serves managed service providers (MSPs) and managed security service providers (MSSPs), as well as industries such as financial and professional services. Key capabilities highlighted include the ability to darken networks using existing firewalls, automate network management through a centralized portal, and protect infrastructure against discovery and targeting. The platform supports distributed workforces and multi-environment deployments. Enclave is backed by notable organizations including Airbus, the UK's National Cyber Security Centre (NCSC), Lorca (a GCHQ-backed cybersecurity accelerator), and Gula Tech Adventures, indicating institutional support from both the private sector and government-aligned cybersecurity bodies.
