The Department of Energy just did something it has never done before.
On March 19, 2026, the Office of Cybersecurity, Energy Security, and Emergency Response (CESER) released its first-ever comprehensive five-year strategic plan. This isn’t just another government report—it’s a clear signal that the federal government expects measurable progress on energy infrastructure security, and it expects it soon.
For energy sector operators, this plan fundamentally changes the conversation around cybersecurity investment and prioritization. Here’s what you need to know and how to prepare.
__________________________________________________
The Three Pillars of the CESER Strategy
The strategic plan is organized around three goals that will shape federal energy security policy through 2030:
Goal 1: Develop World-Class Security Technologies
CESER is investing heavily in advanced security capabilities, including AI-FORTS (Artificial Intelligence for Operationally Resilient Technologies and Systems). This program aims to leverage artificial intelligence to detect threats, maintain operations during incidents, and secure AI-based systems used in energy operations.
What this means for operators: The government is betting on AI-powered security, but these systems require something often overlooked—a comprehensive, accurate model of your network infrastructure. AI can only protect what it can see and understand. Before implementing AI-powered defenses, organizations need to establish foundational visibility into their cyber terrain.
Goal 2: Harden U.S. Energy Infrastructure
This is where the rubber meets the road. CESER’s Project ARMOR initiative has a specific objective: “Within a two-year period, rank and harden defense critical energy infrastructure for national security sites.”
The plan also extends beyond defense-critical facilities, calling for industry-wide hardening across generation, transmission, distribution, and supply chain infrastructure.
What this means for operators: The two-year timeline is significant. It suggests that regulators and federal partners will be looking for demonstrable evidence of infrastructure hardening—not just good intentions or compliance checklists. Operators should prepare to answer questions like:
- What is your current attack surface across IT and OT environments?
- Which vulnerabilities pose the greatest risk to your critical assets?
- How are you prioritizing remediation efforts?
- Can you demonstrate measurable risk reduction over time?
Goal 3: Respond and Recover from Incidents
CESER serves as the lead federal coordinating agency for energy sector emergencies. The plan emphasizes streamlining preparedness processes and standardizing emergency response capabilities.
What this means for operators: Organizations that have documented their network infrastructure and attack paths will be better positioned to respond effectively during incidents. When every minute counts, understanding how systems are connected and how attackers could move laterally becomes critical for containment and recovery.

The Challenge You’re Probably Facing
If you’re like most energy sector security leaders, you’re dealing with a familiar set of problems:
Too many vulnerabilities, too little context. Traditional vulnerability scanners can identify thousands of issues, but they can’t tell you which ones actually threaten your most critical assets. You end up with a backlog that grows faster than you can remediate.
IT/OT convergence creates blind spots. As operational technology becomes more connected, the attack surface expands. But many security tools weren’t designed for OT environments, creating visibility gaps precisely where risk is highest.
Cloud solutions don’t work everywhere. Many security platforms require internet connectivity, which simply isn’t an option for air-gapped control rooms and sensitive OT environments. This leaves critical infrastructure with fewer security options than typical enterprise IT.
Resource constraints are real. The CESER plan itself acknowledges that budget pressures are forcing the agency to “do more with less.” Energy operators face the same challenge—smaller teams, larger attack surfaces, increasing threat levels.

A Different Approach: From Vulnerability Lists to Continuous Threat Exposure Management
The CESER strategy emphasizes resilience—the ability to maintain operations through adverse conditions and recover quickly from disruptions. This requires a fundamentally different approach to security—one that aligns closely with Gartner’s Continuous Threat Exposure Management (CTEM) framework.
Gartner introduced CTEM as a strategic approach that shifts organizations from reactive vulnerability management to proactive, continuous exposure reduction. The framework consists of five stages: scoping, discovery, validation, prioritization, and mobilization. It’s no longer enough to simply find vulnerabilities; organizations must continuously identify which exposures actually matter and drive remediation of the highest-risk issues.
RedSeal is recognized in Gartner’s Exposure Management market, and for good reason. Our platform directly supports the CTEM methodology:
| CTEM Stage |
Traditional Approach |
RedSeal Approach |
| Scoping |
Asset inventories that are often incomplete or outdated |
Cyber terrain mapping that reveals all connected assets—including shadow IT and OT |
| Discovery |
Vulnerability scans that produce thousands of findings |
Attack path analysis that identifies which vulnerabilities create actual risk |
| Validation |
Theoretical severity scores (CVSS) |
Real-world exploitability based on network topology and attacker reachability |
| Prioritization |
Remediate by severity score |
Remediate by attack path risk to critical assets |
| Mobilization |
Tickets assigned without context |
Prioritized remediation with clear risk context and measurable outcomes |
The CESER plan’s emphasis on “measurable hardening progress” and “two-year objectives” aligns perfectly with CTEM principles. Energy operators need to demonstrate not just that they’re finding issues, but that they’re systematically reducing their exposure over time.
This is the shift from asking “What vulnerabilities do we have?” to “How could an attacker reach our critical assets?”—and ultimately to “Can we prove our exposure is decreasing?”
Attack path analysis models your network topology to understand how systems are connected and how an attacker could move from an initial access point to critical assets. Combined with CTEM’s continuous methodology, this transforms security from an endless list of problems into a focused, measurable exposure reduction program—exactly what CESER is expecting operators to demonstrate.

Aligning with CESER’s Two-Year Hardening Mandate
With Project ARMOR’s two-year timeline for infrastructure hardening, energy operators need a structured approach to demonstrate progress. Here’s a practical framework:
Phase 1: Establish Baseline (0-90 days)
Before you can harden infrastructure, you need to know what you’re hardening. This phase focuses on:
- Mapping your cyber terrain across IT and OT environments
- Identifying all network connections, including third-party and vendor access
- Establishing an attack surface baseline
- Documenting critical asset inventory and dependencies
Phase 2: Prioritize and Plan (90-180 days)
With visibility established, focus on what matters most:
- Identify attack paths that pose the greatest risk to critical assets
- Prioritize vulnerabilities based on actual exploitability, not just severity scores
- Develop remediation roadmap aligned with operational constraints
- Establish metrics for measuring hardening progress
Phase 3: Execute and Verify (180+ days)
Implementation with accountability:
- Execute prioritized remediation actions
- Verify hardening effectiveness through continuous modeling
- Document before/after risk posture
- Prepare evidence for regulatory and stakeholder inquiries

The Air-Gapped Reality
One aspect of the CESER strategy that deserves particular attention is its focus on operational technology environments. The plan explicitly prioritizes securing control systems—the physical processes that keep energy flowing.
For many energy operators, this means securing environments where cloud connectivity is prohibited. Control rooms, SCADA systems, and industrial control systems often operate in air-gapped or highly restricted networks.
This creates a significant challenge: many modern security platforms are cloud-native or require internet connectivity for full functionality. When evaluating security solutions, energy operators should ask:
- Does this tool work without internet connectivity?
- Can it be deployed entirely on-premise?
- Will it function in our OT environment without introducing new risk?
The ability to operate in air-gapped environments isn’t a nice-to-have for energy security—it’s a requirement.

Automation Without Cloud Dependency
The CESER plan also emphasizes the need for automation and AI to scale security capabilities. With limited staff and expanding attack surfaces, automation is essential for keeping pace with threats.
But automation in OT environments requires careful consideration. Cloud-based automation platforms may not be suitable for air-gapped infrastructure. On-premise workflow automation that can operate without internet connectivity offers a path forward.
When evaluating automation capabilities, consider:
- Can security workflows run entirely on-premise?
- Does the automation integrate with existing OT security tools?
- Can incident response processes be automated without introducing operational risk?

What Success Looks Like
As the CESER strategy moves from plan to implementation, energy operators will increasingly be asked to demonstrate security progress. Success looks like:
Measurable risk reduction. Instead of vulnerability counts going up, risk scores going down. Attack paths being eliminated, not just vulnerabilities being patched.
Documented due diligence. Clear evidence that leadership has visibility into the attack surface and is making informed decisions about where to invest security resources.
Operational resilience. The ability to maintain critical operations during adverse conditions and recover quickly from incidents.
Regulatory readiness. Documentation and evidence prepared for NERC CIP compliance, federal inquiries, and stakeholder questions about security posture.

The Bottom Line
The DOE’s CESER Strategic Plan 2026-2030 represents a significant milestone in federal energy security policy. For the first time, there’s a clear expectation of measurable progress on infrastructure hardening within a defined timeframe.
Energy operators who can demonstrate visibility into their attack surface, prioritize remediation based on actual risk, and operate security capabilities in OT environments will be well-positioned to meet these expectations.
The strategy is clear. The timeline is defined. The question now is execution.
