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.

Give the Board an OT Network Attacker Can't Fin

For CISOs & Security Leaders

Give the Board an OT Network Attackers Can't Find

Legacy OT is flat, password-dependent, and full of assets you can't patch. BlastShield removes the attack surface entirely, cloaking assets, eliminating credential theft, and enforcing least-privilege segmentation, while mapping cleanly to the frameworks your auditors expect.

The Risk You Own

OT is the exposure the board is now asking about.

Critical infrastructure is a nation-state target, and the usual controls don't translate to environments you can't patch or take offline.

Credential theft is the #1 vector

Passwords and brittle 2FA remain the easiest way in. Roughly 70% of IIoT devices still run default passwords. One stolen credential can reach the plant floor.

Flat networks invite lateral movement

Flat networks invite lateral movementOnce inside, an attacker moves freely across a flat OT network. Detection-first tools tell you it happened; they don't stop it.

Exposed, unpatchable assets

Public-facing IPs and legacy PLCs are discoverable and unpatchable, a standing invitation to AI-driven reconnaissance.

Mandates with real deadlines

NERC CIP, IEC 62443, and TSA directives carry timelines and audits, and hardware-led projects mean outages you can't schedule.

The BlastShield answer

Protection-first, not detection-first

BlastShield changes the game: it makes assets non-discoverable and access identity-bound, so most attack paths simply cease to exist.

Eliminate credential theft

Phishing-resistant passwordless MFA (QR challenge-response, biometrics, device keystore, human-in-the-loop) makes stolen credentials useless.

Cloak the attack surface

A secure overlay hides assets from scans and AI reconnaissance. If it can't be found, it can't be targeted.

Contain the blast radius

Software-defined microsegmentation enforces least privilege and stops lateral movement, without a network redesign.

Auditable remote access

Default-deny policy, exportable syslog event logs, and recorded BlastAccess sessions give defensible evidence for auditors and the board.

Requirement Mapping

IEC 62443-3-3 Security Requirements — BlastShield Coverage

IEC 62443-3-3 defines 51 System Security Requirements (SRs) across seven Foundational Requirements (FRs). Below are the SRs most directly addressed by BlastShield.

Framework

How BlastShield supports it

NIST SP 800-207 (Zero Trust)

Per-session authentication and authorization, least-privilege access, and an assume-breach posture enforced by the Orchestrator (policy) and Gateway/Client/Agent.

IEC 62443 (zones & conduits)

Software-defined micro-perimeters and egress policies implement zoning and controlled conduits without physical re-architecture.

NERC CIP (ESP & remote access)

Cloaking, passwordless MFA, least-privilege access, and session recording support electronic access controls and auditable remote access.

TSA Security Directives

Segmentation, access control, and IT/OT separation support the directives, with rapid deployment to meet timelines without downtime.

Independently Validated

BlastShield's Zero Trust Network Access performance has been independently evaluated by The Tolly Group, and its protection model is documented across 23 real OT attacks in the BlastWave Hackopedia, including Colonial Pipeline, NotPetya, and Volt Typhoon.

Proof, not promises. Trusted across 500M+ device hours of preventing cyberattacks in critical infrastructure.

CISO FAQ

What security leaders ask first

IEC 62443-3-3 defines 51 System Security Requirements (SRs) across seven Foundational Requirements (FRs). Below are the SRs most directly addressed by BlastShield.

How does BlastShield reduce the OT attack surface?

It places OT systems on a cloaked overlay so they do not respond to ICMP, ARP, or port scans and cannot be discovered by unauthorized users, scanners, or AI reconnaissance. Combined with passwordless MFA and least-privilege microsegmentation, it removes the exposed attack surface rather than defending it.

‍

Does BlastShield help with OT compliance mandates?

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 does BlastShield stop credential theft and phishing?

It replaces passwords and brittle 2FA with phishing-resistant passwordless MFA (QR challenge-response, biometrics, device keystore, human-in-the-loop), so attackers cannot gain access with stolen credentials, the number-one breach vector.

Can we prove and audit remote access for the board and auditors?

Yes. Access is default-deny and policy-driven, event logs export to syslog, and BlastAccess records remote desktop sessions for forensics and audit, giving defensible evidence of who accessed what and when.
