Rock-sec OT playbook
Energy utilities, TSOs and DSOs
RockSec supports utility organizations operating large-scale OT environments in addressing the challenges of limited visibility, complex system dependencies, and increasing cyber risk exposure. Where thousands of connected devices make comprehensive testing impractical, RockSec applies a risk-based, architecture-led approach to cybersecurity. This includes establishing full visibility through asset discovery and mapping of IT and SCADA environments, followed by targeted vulnerability assessments to identify critical assets and high-risk exposure points. By prioritizing devices and third-party vendors based on operational impact and threat likelihood, RockSec enables utilities to focus efforts on deep technical evaluations—covering software, firmware, hardware, and network interfaces—where risk is greatest. This approach allows organizations to transition from reactive to proactive security management, strengthen regulatory compliance, reduce the likelihood of service disruption, and build a resilient OT security program with continuous monitoring aligned to 24x7x365 operational requirements.

Oil & Gas and Chemical
RockSec supports chemical manufacturing organizations in addressing the risks associated with fragmented OT and IT environments, where lack of centralized visibility and inconsistent security practices can hinder effective risk management and incident response across global production sites. By applying a structured, risk-based approach, RockSec conducts comprehensive assessments including site walks, technical validation, and threat modeling to establish a clear understanding of the organization’s security posture. Leveraging industry-aligned frameworks such as NIST-CSF, RockSec defines common risk metrics, builds centralized visibility through asset and risk registers, and develops tailored security profiles based on site maturity and operational criticality. This enables organizations to prioritize initiatives through a cost-, complexity-, and impact-driven roadmap that aligns with their ability to execute. The result is improved security visibility, measurable risk reduction, and stronger alignment between security and production teams, while laying the foundation for a scalable, holistic OT cybersecurity strategy across global operations.

Food & beverages industry
RockSec supports food and beverage manufacturers in securing newly built or modernized “factories of the future,” particularly in environments where evolving OT threats require late-stage security validation and enhancement prior to go-live. In cases where long-term facility design and construction efforts have overlooked critical security gaps, RockSec applies a structured, risk-based approach that includes architecture review, site assessments, and threat modeling to identify and document vulnerabilities through a centralized risk register. By coordinating closely with client teams and multiple third-party stakeholders, including engineering, automation, and installation partners, RockSec establishes a consistent security baseline across the facility. This enables the development of a strengthened, modernized architecture aligned with CPwE and Purdue models, while ensuring that security controls are embedded without disrupting operations. The outcome is a more resilient and secure OT environment, improved visibility into risks, and a clear, prioritized roadmap for future investments such as OT monitoring, SIEM integration, firewall enhancements, and risk-based security management.

Logistics and Distribution Centers
RockSec supports global logistics organizations in securing large, distributed OT environments by establishing standardized, scalable security operations across diverse facilities. In environments where limited global security standards and high volumes of false positives hinder effective threat detection, RockSec implements a structured approach combining OT sensor deployment, integration with existing security platforms, and automation through SOAR (Security Orchestration, Automation, and Response). By deploying and tuning OT sensors across multiple sites, integrating telemetry into SOC workflows, and aligning with firewalls, endpoint security, and CMDB systems, RockSec will enable centralized visibility and control. Through the implementation of automated response processes, RockSec will support reducing alert noise, improve detection accuracy, and enhance operational efficiency. Additionally, RockSec provides transitional support by triaging alerts and embedding OT security expertise, enabling internal SOC teams to build capability and take ownership over time. The result is a mature, standardized OT security operations model with measurable reductions in alert volumes, improved response effectiveness, and a scalable foundation for continuous security improvement across global operations.

In scenarios involving large-scale deployments—such as selecting OT sensors across hundreds of global sites, RockSec provides an independent, structured evaluation approach to ensure objective and outcome-driven decisions. This includes stakeholder alignment through cross-functional input, narrowing vendor options based on defined criteria, and conducting controlled laboratory testing of shortlisted solutions. RockSec works with client teams to develop a transparent, qualitative scoring and evaluation framework that assesses each technology based on performance, security capabilities, scalability, and operational fit—independent of external business influences. This enables organizations to confidently select the best-fit solution for their environment, maintain strategic partner relationships, and support global deployment at scale. The outcome is a defensible, unbiased selection process aligned with business objectives, ensuring long-term effectiveness and consistency across all operational sites.
