BlastShield is BlastWave’s Zero Trust network access solution for OT environments. It uses a software-defined perimeter approach to help organizations reduce risk from stolen credentials, simplify access control, cloak critical systems, secure remote access, and segment OT networks.

How does BlastShield help stop OT attacks before they start?

BlastShield helps stop OT attacks before they start by requiring authentication and authorization before users or devices can access protected systems. It combines network cloaking, phishing-resistant access, secure remote connectivity, and software-defined segmentation to reduce exposure and limit lateral movement.

What is the BlastShield Security Gateway?

The BlastShield Security Gateway is a hardware-independent software package that can be installed in a VM, container, or pre-installed appliance. It delivers network cloaking, terminates secure remote access connections, and uses software-defined segmentation to secure OT networks.

What is the BlastShield Client?

The BlastShield Client is a Zero Trust client for secure OT connectivity. It supports Windows, Mac, and Linux, allowing authorized users to connect securely to approved OT systems without disrupting existing operations.

What is the BlastShield Authenticator?

The BlastShield Authenticator provides passwordless authentication using a QR code challenge-response, localized biometric authentication, and the device keystore. It is designed to prevent credential theft, phishing, and AI-powered attacks while keeping a human in the loop.

BlastAccess is BlastWave’s secure remote desktop connectivity solution. It provides high-performance remote access with session recording, while removing open ports and reducing risks from browser hijacking, password theft, PAM weaknesses, and web-based RDP exposure.

What does the BlastShield Agent do?

The BlastShield Agent helps secure servers by requiring a verified BlastShield client before a connection can be made. It supports Windows, Mac, and Linux and helps turn protected servers into Zero Trust-controlled assets.

What does the BlastShield Orchestrator do?

The BlastShield Orchestrator manages real-time policy enforcement across the network. It can be deployed on-premises or in the cloud and helps ensure users and devices connect only to the systems they are authorized to access.

How does BlastShield support network cloaking?

BlastShield supports network cloaking by requiring users and devices to authenticate and authorize before access is granted. This helps make protected systems non-discoverable to unauthorized users and reduces the value of reconnaissance.

How does BlastShield support OT network segmentation?

BlastShield supports OT network segmentation through software-defined access controls that divide the network into isolated segments. This limits lateral movement and helps contain the impact of a breach.

Zero Trust That Doesn't Touch a Single PLC

For OT & Controls Engineers

Zero Trust That Doesn't Touch a Single PLC

You can't patch a 15-year-old RTU, take the line down, or bolt another firewall onto a flat network. BlastShield cloaks your assets, segments the network, and delivers passwordless remote access as a software overlay, with no agents on OT devices, no new hardware, and no downtime.

The Reality on the Plant Floor

The constraints are real. The workarounds shouldn't add risk.

OT security has to respect availability, legacy hardware, and the way your team actually works. Traditional tooling ignores all three.

Unpatchable legacy

PLCs and RTUs that can't be patched or rebooted still carry known CVEs. You need to protect them without touching them.

Flat networks

High-availability designs left the network flat. One foothold means lateral movement everywhere, and firewall ACLs are fragile and slow to change.

Flat Clunky remote access

VPNs drop vendors onto the whole network; web RDP and PAM add open ports and browser risk. Neither fits how technicians work.

How BlastShield Works

A software overlay that engineers out the risk

BlastShield builds a cloaked, encrypted overlay on top of your existing network. Assets become invisible to scans and reachable only after authorized, passwordless access.

Gateway at the IT/OT boundary

Deploy the Security Gateway as a VM, container, or certified appliance. It cloaks the OT systems behind it, so they stop responding to ICMP, ARP, and port scans.

Legacy stays untouched

PLCs, RTUs, and HMIs sit behind the Gateway as protected Endpoints. No agents, no firmware changes, a virtual air gap around fragile devices.

Passwordless remote access

The Client (Windows/Mac/Linux) plus phishing-resistant authenticator gives least-privilege access. BlastAccess adds recorded remote desktop with no open ports.

Software-defined segmentation

Create micro-perimeters around devices or groups in hours. Stop lateral movement without ACL surgery, new hardware, or a maintenance window.

Field proof · VPN → ZTNA in 10 minutes

"BlastShield filled our needs with their patented solution, giving secure access to hybrid data services hosted both in the cloud and on-premise."

Emil Erlandsson, VP of Professional Services, A2i, cut over from a legacy VPN to Zero Trust access in the time it takes to boil an egg. Backed by 500M+ device hours of preventing cyberattacks.

Engineer FAQ

The questions your team will ask

Do I have to install software on my PLCs or RTUs?

No. Cloaking runs on a Gateway at the IT/OT boundary, not on the OT devices. Legacy PLCs, RTUs, and HMIs sit behind the Gateway as protected Endpoints and need no changes, creating a virtual air gap around fragile equipment.

Will deploying BlastShield require downtime or a network redesign?

Yes. The architecture maps to NIST SP 800-207, IEC 62443, NERC CIP, and TSA Security Directives, and because controls are software-defined they deploy without the outages of hardware-led projects. This supports, but does not replace, formal certification.

How do engineers get secure remote access without a clunky VPN or web RDP?

The BlastShield Client (Windows, macOS, Linux) gives least-privilege access using phishing-resistant passwordless authentication. BlastAccess adds secure remote desktop with session recording and no open ports.

What does BlastShield need to run?

The Gateway runs as a VM (2 vCPU, 4GB RAM), a container, or a certified appliance from OnLogic or Axiomtek. The Orchestrator runs on-premises (including fully air-gapped) or in the cloud.
