Versions:
BlastShield 1.13.2 by BlastWave Inc. is a zero-trust network access (ZTNA) client engineered to establish a software-defined perimeter that shields both operational technology (OT) and industrial internet-of-things (IIoT) devices as well as conventional IT assets from unauthorized lateral movement. Positioned within the Network Security category, the application replaces legacy VPNs with micro-tunnels that authenticate every connection request before granting least-privilege access to specific hosts and services, making it suited for protecting manufacturing lines, power grids, building-automation controllers, remote PLC panels, and hybrid cloud workloads without exposing entire network segments. Security teams deploy the lightweight client on Windows endpoints to create encrypted, identity-bound pathways that cloak critical controllers, SCADA gateways, and servers from public discovery, while maintenance engineers use the same interface to reach isolated assets for diagnostics or firmware updates without reconfiguring firewalls. Because the 1.13.2 release is the first generally available version, organizations receive the latest feature set immediately upon installation, including mutual TLS device identity, continuous posture verification, and seamless failover across redundant gateways. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version, and supporting batch installation of multiple applications.
