Operational Technology & Specialist Security Reviews
Operational and specialised technology environments operate under constraints that standard IT security approaches do not address. Availability takes precedence over confidentiality. Patching cycles are measured in months or years, not days. Legacy protocols lack built-in authentication. And the consequence of a security failure is not data loss, it is operational disruption, safety risk, or physical impact.
London Strategy Centre provides security assessments designed specifically for these environments, addressing the distinct risk profiles of industrial systems, payment environments, connected platforms, and enterprise configurations.
Standard IT security models do not translate to operational environments
The frameworks, tools, and assumptions that govern enterprise IT security were designed for environments where systems can be patched, rebooted, and reconfigured with relative agility. Operational technology environments, industrial control systems, manufacturing networks, building management systems, and critical infrastructure, do not operate under these assumptions.
Applying IT security models directly to OT environments creates two risks: controls that are technically incompatible with operational requirements, and a false sense of security based on assessments that did not account for the constraints of the environment. Effective OT security requires assessments designed for these conditions.
Four specialist security disciplines
LSC's operational technology and specialist security reviews are structured to address the specific challenges of non-standard technology environments.
Point-of-Sale Security Hardening
Retail payment environments are frequent targets for cyber-attacks because they process high volumes of financial data through distributed systems with varied configurations. Security reviews examine system configurations, network segmentation, access controls, and monitoring capabilities to identify weaknesses and strengthen protection for payment systems and customer data. Findings are aligned with PCI DSS requirements where applicable.
Industrial & Operational Technology Security
Industrial control systems, SCADA environments, and manufacturing networks require strong security controls to prevent disruption that could affect production, safety, or service delivery. Assessments review network architecture, remote access controls, network segmentation between IT and OT environments, and the security of legacy protocols - providing prioritised recommendations that account for operational constraints.
Connected Platform Risk Assessments
Connected systems and IoT platforms expand the attack surface by introducing networked devices with varied security capabilities into operational environments. Risk assessments identify vulnerabilities within connected devices, communication protocols, and integrated systems - evaluating how the platform's security posture affects the broader organisational environment.
Secure System Configuration
Enterprise systems deployed without security hardening carry unnecessary risk from default settings, unused services, and permissive access configurations. Configuration guidance ensures systems are deployed using security best practices, with baseline configurations that reduce vulnerabilities and improve resilience across IT and OT environments.
Assessments designed for operational reality
Every assessment LSC delivers in operational technology environments is designed with operational continuity as a primary constraint. Testing approaches are non-disruptive. Recommendations account for patching limitations, legacy system dependencies, and safety requirements. The aim is to strengthen security within the operational reality of the environment - not to impose controls that conflict with it.
Who this is for
These services are designed for organisations operating industrial control systems and SCADA environments, retailers and payment processors managing distributed point-of-sale systems, organisations deploying or managing connected IoT platforms, enterprises requiring secure baseline configurations across complex environments, and operations directors balancing security improvement with operational continuity.
Frequently Asked Questions
Yes. LSC scopes all OT assessments carefully to work within operational constraints. Passive assessment techniques are used where active testing would carry operational risk, and out-of-hours windows can be arranged.
LSC assesses industrial control systems (ICS), SCADA platforms, distributed control systems (DCS), point-of-sale environments, building management systems, and connected IoT infrastructure.
OT environments prioritise availability and safety over confidentiality — the opposite of most IT environments. Legacy systems with limited patching capability, long replacement cycles, and safety-critical functions require a fundamentally different security approach.
Yes. LSC can align OT security assessments with IEC 62443, NIST SP 800-82, and sector-specific frameworks including those applicable to critical national infrastructure.
