The energy sector is facing a significant regulatory shift. Historically, the most
stringent cybersecurity requirements were reserved for high and medium-impact facilities.
However, with the upcoming enforcement of the [NERC CIP-003-9 reliability standard](https://www.nerc.com/pa/Stand/Reliability%20Standards/CIP-003-9.pdf),
strict access controls are being extended to the edge of the grid. This whitepaper
explains how energy utilities can quickly achieve compliance for their low-impact
Bulk Electric System (BES) cyber assets—implementing robust multi-factor authentication
for third-party vendors without requiring network or configuration changes.

## **Understanding Low-Impact BES Cyber Assets**

In the context of the North American Electric Reliability Corporation (NERC), a 
low-impact BES cyber asset refers to infrastructure that, while critical to the 
overall grid, does not pose an immediate, catastrophic risk to the bulk electric
system if compromised individually. These include smaller distribution substations,
remote wind farms, solar arrays, and municipal hydroelectric plants.

Because of their distributed nature and lower individual risk profile, these assets
have traditionally operated with lighter security controls. They frequently rely
on legacy operational technology, basic perimeter firewalls, and simple password-
based authentication. They are often unstaffed, requiring remote access for routine
maintenance and troubleshooting by third-party integrators and vendors.

## **The Impact of NERC CIP-003-9**

Effective April 2026, the NERC CIP-003-9 standard fundamentally alters how these
low-impact assets must be secured. A core component of this mandate focuses on Vendor
Electronic Remote Access. Regulators recognise that supply chain vulnerabilities
and compromised vendor credentials represent a systemic threat to the grid.

Under the new rules, simply providing a vendor with a shared password or a generic
virtual private network (VPN) connection is no longer compliant. Utilities must 
enforce strict identity verification, primarily through multi-factor authentication,
before allowing any remote connection to a low-impact asset. The challenge is that
the legacy programmable logic controllers and human-machine interfaces at these 
sites lack the native capability to prompt for or validate modern authentication
tokens.

## **The Challenge with Third-Party Access**

Securing third-party access introduces significant operational friction. Vendors
often refuse to install utility-managed VPN clients on their corporate laptops. 
Furthermore, coordinating complex network configurations—such as opening inbound
firewall ports or managing static IP addresses across cellular modems and satellite
connections—adds weeks of delay to critical maintenance tasks.

Utilities need a solution that secures the connection without touching the legacy
endpoint, modifying the network perimeter, or burdening the third-party vendor with
complex software installations.

## **The Agilicus AnyX Solution: Compliant, Quick, and Simple**

Agilicus AnyX offers a zero trust identity-aware proxy that solves the NERC CIP-
003-9 compliance challenge for low-impact assets elegantly and efficiently. It allows
utilities to be compliant, be quick, and be simple, with absolutely no changes to
the existing infrastructure.

 * **Multi-factor authentication natively:** Agilicus AnyX acts as an intermediary
   layer. It intercepts the vendor’s connection request, challenges them with multi-
   factor authentication using their existing corporate identity, and only brokers
   the connection to the legacy device once their identity is proven. The legacy
   device never knows the difference.
 * **No network or configuration changes:** The platform utilises a lightweight,
   outbound-only connector. There is no need to open inbound firewall ports, configure
   complex VPN routing, or manage public IP addresses. The low-impact asset remains
   completely invisible to the public internet.
 * **Frictionless for third parties:** Vendors access the specific resources they
   need (such as a [remote desktop](https://www.agilicus.com/infosheet/zero-trust-vnc-remote-desktop/)
   or web interface) directly through their standard web browser. There are no VPN
   clients to install and no complex login procedures to learn.

## **Conclusion**

Meeting the April 2026 deadline for NERC CIP-003-9 does not require a massive capital
expenditure to rip and replace operational technology, nor does it require a redesign
of your network architecture. By leveraging [a zero trust architecture](https://www.agilicus.com/what-we-do/vpn-alternative/)
like Agilicus AnyX, energy utilities can secure their low-impact BES cyber assets,
streamline third-party access, and achieve full compliance with a system that is
fundamentally quicker and simpler to deploy.
