In oil & gas and utility environments, identity issues rarely present themselves as abstract security concerns. They surface in moments that directly impact operations. A crew cannot access a system during outage restoration, a vendor retains unnecessary access into a control environment, or engineers accumulate privileges across systems over time.
These situations point to a common underlying issue: access is not consistently defined or governed.
Many organizations respond by investing in Identity and Access Management (IAM) platforms, expecting technology to solve the problem. Modern IAM tools promise automation and improved security, making them a logical starting point. But while these platforms provide an strong foundation, they do not address the more complex challenge of how access decisions are made and maintained over time.
Across critical infrastructure operations, access is inseparable from reliability. Control room operators, field technicians, plant engineers, and external vendors all rely on timely, appropriate access to systems that support generation and distribution. During outages or emergency response, access is often given immediately to stabilize conditions. However, it is rarely revisited with the same urgency. Over time, access granted for specific needs persists across IT systems and SCADA environments. This creates fragmented visibility and makes it difficult to answer an important question: who has access to what, and why.
At CTG, we view IAM as a framework of processes and governance models designed to ensure the right individuals have the right access at the right time. In energy environments, that definition must extend further: making sure access reflects real operational needs and is always validated across both IT and operational technology (OT) systems. Prioritizing software over the operational discipline required to make it effective introduces risk directly into the systems that support reliability and regulatory compliance.
We have seen organizations invest heavily in IAM implementations that look complete on paper, but struggle to deliver the intended outcomes in practice. It makes sense that, according to the Identity Security Threat Landscape report, 93% of organizations have experienced multiple identity-related breaches in the past 12 months. In energy environments, where identity spans IT, OT, and a wide vendor ecosystem, an overreliance on technology alone often expands access faster than it can be effectively governed.
Why IAM Software Is Often Overestimated
In conversations with our clients, in energy and beyond, we see a persistent belief that deploying Single Sign-On (SSO), Multi-Factor Authentication (MFA), or governance tools equates to IAM maturity. IAM vendors often reinforce this by positioning IAM as a product.
In energy organizations, this assumption is amplified by the divide between enterprise IT and operational systems. Access to corporate platforms such as cloud services and productivity tools is often centralized and well-controlled. Meanwhile, access to SCADA systems, energy management systems (EMS), plant control environments, and field applications is managed seperately, frequently by different teams. This creates a disconnect where IAM appears mature from an enterprise perspective, while critical operational systems are governed inconsistently.
Authentication improvements can create visible progress with smoother logins and measurable adoption, but they only represent part of the challenge. Authentication confirms identity; it does not determine whether that identity should have access to critical systems. That distinction is where most IAM gaps emerge.
The real complexity lies in access decisions: who gets access, for how long, and under what conditions. In critical infrastructure, these decisions must reflect how work is actually performed across outage response, scheduled maintenance, and vendor-supported projects. Without governance that accounts for these realities, access decisions persist long after the need has passed.
Over time, permissions accumulate across systems, often built over years of operational activity and rarely revisited. Redefining that access requires coordination across IT, security, engineering, operations, and compliance —a level of alignment many organizations struggle to achieve.
This dynamic is reinforced by how risk appears. Authentication failures are immediate and visible. Poor access decisions accumulate quietly, often surfacing during audits or operational incidents —when the stakes are highest.
Why IAM Success in Energy Depends on Structure
Based on our work with clients, we know that IAM success depends less on tools and more on structure.
IAM is only effective when identity lifecycle, authentication, and authorization are connected to a clear access model rooted in operational reality. For energy organizations, this means defining access around real roles like grid operators, control engineers, plant personnel, field technicians, and external service providers, and ensuring those roles are consistently enforced across systems.
If roles are unclear or inconsistently applied, automation can amplify risk by extending access across interconnected systems. In energy environments, where systems directly influence physical infrastructure, this risk extends beyond data exposure into operational disruption and safety impact.
IAM cannot be treated as a one-time deployment. It must operate as an ongoing discipline, adapting to infrastructure changes, workforce turnover, vendor involvement, and evolving regulatory requirements for the energy industry, such as NERC CIP.
Where IAM Programs Commonly Break Down
Despite years of evolution, IAM failures tend to follow predictable patterns. Organizations invest in modern platforms but continue to manage access in fragmented ways, resulting in environment that reflect years of accumulated decisions rather than deliberate design.
No Clear Ownership for Access Approvals
Ownership of access is often unclear, particularly when systems span multiple domains. This leads to delayed approvals during time-sensitive work or approvals granted without a full understanding of risk.
Temporary Exceptions Become Permanent Risk
Access granted during outages, emergency repairs, or vendor engagements is often left in place. Without structured review processes, these temporary permissions create long-term exposure within control systems and operational platforms.
IAM Is Treated as a One-Time Project
IAM is frequently tied to modernization or compliance initiatives. In reality, access must be continuously governed to reflect changing systems, evolving infrastructure, and ongoing operational demands.
The Impact of Poor IAM Execution for Energy Organizations
When IAM is not properly managed in energy environments, the impact is immediate and operational. Poorly governed access to control systems, substations, generation facilities, or remote assets can disrupt service delivery and introduce safety risks. Excess access increases the risk of unauthorized activity, while insufficient access slows down technicians and operators working under time-sensitive conditions.
Onboarding and offboarding processes often struggle to keep pace with operational needs. Contractors may wait for access to begin critical maintenance, while field teams encounter delays during outage response, extending restoration timelines and affecting reliability metrics. Inconsistent or overly restrictive controls drive workarounds that introduce additional risk. These challenges are compounded by compliance obligations, as organizations must demonstrate control over access to systems supporting critical infrastructure.
What Effective IAM Programs Do Differently
High-performing IAM programs treat access as a core operational capability, not just a security control. They establish clear ownership of access decisions and embed identity governance into the daily workflows of control rooms, field operations, plant management, and vendor coordination.
In practice, this means continuously aligning access to operational needs by making sure users have the right level of access for the right duration. As IT and OT environments converge and systems become more interconnected, maintaining accurate, real-time access control becomes essential to ensuring both security and operational resilience.
The IBM Cost of a Data Breach Report shows that among organizations reporting AI-related breaches, 97% identified gaps in access controls. In energy environments, these gaps often stem from access that no longer reflects current operational responsibilities but remains active within critical systems.
In our experience, organizations that focus on operational alignment and governance achieve better outcomes.
At CTG, we help energy organizations move beyond fragmented identity controls by assessing access across both IT and OT environments. We identify where access decisions introduce operational risk, tie those gaps to measurable outcomes such as downtime, safety exposure, and compliance risk, and deliver a phased roadmap that strengthens governance without disrupting critical operations.
