BlastShield maps directly to the electronic security perimeter, remote access, and access control requirements that bulk electric system operators must satisfy under NERC CIP — without adding firewall complexity or requiring new hardware.
Electronic Security Perimeters
Systems Security Mgmt
Config & Vulnerability Mgmt
The North American Electric Reliability Corporation's Critical Infrastructure Protection (NERC CIP) standards are mandatory cybersecurity requirements for owners and operators of the North American Bulk Electric System (BES). Enforced by NERC and regional entities with penalties reaching $1 million per violation per day, they are among the most consequential cyber regulations in any industry.
NERC CIP covers the full lifecycle of BES Cyber System security: how assets are identified and categorized, how electronic perimeters are established, how remote access is controlled, how personnel are trained, and how incidents are managed and recovered from.
The standards most directly addressed by an OT network access solution like BlastShield are CIP-005 (Electronic Security Perimeters), CIP-007 (Systems Security Management), and CIP-010 (Configuration Change Management and Vulnerability Assessments).
Who is covered? NERC CIP applies to registered entities in the bulk power system: transmission owners and operators, generation owners and operators, load-serving entities, and reliability coordinators. Coverage extends to high- and medium-impact BES Cyber Systems and their associated Electronic Access Points (EAPs).
Interactive Remote Access (IRA) is one of the most heavily audited areas. CIP-005 R2 requires that all IRA to high- and medium-impact BES Cyber Systems use encryption, multi-factor authentication, and an Intermediate System that prevents direct connectivity from external networks. BlastShield's architecture satisfies all three.
The table below maps key NERC CIP requirements to specific BlastShield capabilities. Use this as the starting point for your compliance documentation.

Coverage
CIP-005 R1
Electronic Security Perimeter
Define and control all Electronic Access Points to BES Cyber Systems
Identify the ESP boundary. All connections into the ESP must pass through a documented Electronic Access Point with inbound and outbound access control.
BlastShield's Software-Defined Perimeter establishes a cryptographically enforced access boundary. No unauthorized device can reach a BES Cyber System — not because a firewall rule blocks it, but because it is literally invisible to unauthenticated endpoints. The BlastShield Security Gateway acts as a documented, auditable EAP for every protected system.

CIP-005 R2
Interactive Remote Access Management
MFA + encryption + Intermediate System for all IRA to high/medium impact BES Cyber Systems
Require: (1) encryption for all IRA sessions; (2) multi-factor authentication before granting access; (3) an Intermediate System so external parties never directly connect to BES assets.
BlastShield satisfies all three simultaneously. The BlastShield Security Gateway acts as the Intermediate System — external users authenticate to the gateway, never to the asset directly. All tunnels use strong end-to-end encryption. The BlastShield Authenticator provides phishing-resistant passwordless MFA (biometric + QR challenge-response + device keystore), far exceeding the minimum MFA bar. BlastAccess adds session recording for auditability.

CIP-007 R1
Ports and Services
Disable all unnecessary ports and services on BES Cyber System components
Identify all enabled ports and services. Disable any that are not needed for normal operations or security functions. Document and justify all enabled ports.
Network Cloaking removes BES assets from the visible network entirely. Protected systems respond only to authenticated BlastShield clients — all other traffic is silently dropped. This functionally eliminates open ports as an attack surface without requiring per-device OS-level hardening on legacy systems that cannot be patched.

CIP-007 R5
System Access Controls
Limit access to only necessary BES Cyber System capabilities for each user; manage generic and shared accounts
Implement least-privilege access. Define minimum necessary access for each user. Restrict generic or shared account usage. Enforce session timeouts and authentication requirements.
BlastShield enforces least-privilege access at the application level via the Orchestrator. Each user or role is granted access only to the specific BES Cyber Systems — down to individual PLCs, HMIs, or SCADA interfaces — they need. No user can see or reach systems outside their defined scope, even on a flat Layer 2 network. Shared accounts are eliminated by the identity-based architecture.
Full Coverage
CIP-010 R1
Configuration Change Management
Maintain a baseline configuration for each BES Cyber System; authorize and document all changes
Document and maintain a configuration baseline. Verify configuration before changes. Detect unauthorized modifications within 35 days.
The BlastShield Orchestrator maintains a centralized, auditable policy record for all access configurations and network topology. Any change to access permissions, gateway configuration, or segment definitions is version-controlled and logged. This creates a clear, defensible baseline that maps to BES Cyber System configuration documentation requirements.
Partial Coverage
CIP-010 R3
Vulnerability Assessments
Perform vulnerability assessments of BES Cyber Systems; remediate or document identified vulnerabilities
Annual paper-based or active vulnerability assessments. Identify, document, and track remediation of vulnerabilities in BES Cyber Systems.
Network Cloaking eliminates the reconnaissance phase that vulnerability-based attacks depend on — attackers cannot discover or fingerprint systems to exploit. For legacy systems that cannot be patched, BlastShield's "virtual air-gap" ensures unpatched CVEs are operationally irrelevant because the vulnerable surface is never exposed. This dramatically reduces the remediation backlog that stalls compliance programs.
Partial Coverage
CIP-004 R4
Access Management
Implement access management processes; revoke access within 24 hours of role change or termination
Authorize and periodically review access to BES Cyber Systems. Revoke access within 24 hours of personnel changes. Maintain access logs.
Access revocation in BlastShield is immediate and centralized through the Orchestrator. Removing a user from a group or deactivating their identity instantly terminates all BlastShield access — there are no per-device credentials to hunt down or VPN tunnel entries to remove. All access events are logged with user identity, timestamp, and target system.
Full Coverage
CIP-013 R1
Supply Chain Risk Management
Manage cybersecurity risks from vendor remote access
Develop plans to identify and address supply chain risks, including controls for vendor-initiated remote access sessions.
BlastAccess provides a dedicated vendor remote access channel with session recording, time-limited access grants, and identity-bound authentication. Vendor sessions are isolated to their specific maintenance enclave — a compromised vendor cannot pivot to adjacent systems. Session recordings provide forensic evidence for supply chain audits.

Most organizations struggle with NERC CIP because legacy tools force a choice between security and operational continuity. BlastShield eliminates that tradeoff.
The BlastShield Security Gateway creates a verified Electronic Security Perimeter without requiring physical network redesign. All access is controlled at the identity layer — before any packet is exchanged. Undocumented connections are structurally impossible.
The BlastShield Authenticator combines biometric verification, QR-code challenge-response, and device keystore cryptography. There are no passwords to steal, no OTP codes to intercept. This exceeds NERC CIP's Interactive Remote Access authentication standard and eliminates the most common breach vector in energy infrastructure.
BES Cyber Systems protected by BlastShield are invisible to network scans and probes. Unauthorized parties cannot discover, fingerprint, or exploit what they cannot see. This addresses the port-and-services hardening requirement without requiring OS-level changes on unpatchable legacy hardware.
BlastAccess records all remote desktop sessions with full fidelity — keystroke logging, screen capture, and protocol metadata. Every access event is logged with user identity, source, destination, and duration. Audit evidence is available for NERC auditors on demand, without relying on SIEM correlation.
BlastShield operates at Layer 2 and Layer 3 without requiring IP reconfigurations or production outages. Security zones can be defined in hours, not months. Least-privilege access policies are enforced at the application level — engineers see only the systems they're authorized for, even on a flat network.
The BlastShield Orchestrator provides a single pane of glass for access policy, segment configuration, and identity management — deployable on-premises or in the cloud. Configuration baselines are documented, version-controlled, and exportable for compliance submissions. Access can be revoked instantly across all systems simultaneously.
Most NERC CIP compliance programs are built around IT security controls: firewalls, SIEMs, PAM tools, and identity governance platforms. These work well for IT environments. They consistently fail in OT environments for three reasons.
Legacy systems cannot be hardened. The RTUs, PLCs, and SCADA systems at the core of BES infrastructure run on firmware from the early 2000s. They cannot be patched, cannot run endpoint agents, and cannot be taken offline for updates. Traditional security tools that require OS-level access don't apply.
Firewall-based segmentation is fragile. Complex ACL rulesets require constant maintenance. Human misconfiguration is the leading cause of firewall-related incidents. In highly dynamic OT environments where contractors come and go and operational needs change weekly, firewall-based control creates compliance gaps faster than auditors can find them.
VPNs grant too much access. Interactive Remote Access using standard VPNs grants broad network-level access. Under CIP-005 R2, this must be restricted using an Intermediate System. Most VPN architectures weren't designed for this constraint and require expensive add-on products to comply.
The BlastShield approach: Rather than adding security layers on top of a vulnerable architecture, BlastShield changes the architecture. The OT network is overlaid with a cryptographically enforced access layer. Authorized users authenticate and establish point-to-point tunnels to specific assets. Everything else is invisible. There are no open ports, no exposed management interfaces, and no pathways for lateral movement — by design, not by firewall rule.
Deployment without downtime: BlastShield can be deployed in hours on existing infrastructure as a software-only overlay. No hardware replacements, no IP address changes, no production outages. Compliance improvements are visible to auditors immediately after deployment — not after a 12-month firewall refresh cycle.
Our European compliance specialists help OT operators develop a defensible compensating control architecture that addresses both CRA and NIS2 — before enforcement deadlines arrive.
