Cyber Managed Services

Build digital trust through advanced cybersecurity managed services

Adversarial attacks are increasingly targeting the operational technology (OT) that underpins critical infrastructure operations. Preventing these attacks from affecting the safety, reliability and resilience of your operations requires carefully integrated security measures.

But securing these often mission-critical systems can be challenging for organizations with insufficient visibility into OT-specific security risks and regulatory requirements.

Our teams of engineers, security specialists and former operators help you gain a panoramic view of your OT security risks. This lets you identify new threats faster and prepare, respond and emerge more confident from OT security incidents.

Our approach

Our services are about more than checking boxes. We focus on initiatives and managed services that measurably improve your security posture.

We’ll help you transform how you defend your operations with a suite of customizable services tailored to your unique business needs across risk, resilience, recovery and reputation management. Our holistic approach combines the power of your existing security controls and enhanced technology with our deep human expertise. This helps you secure your OT, IoT and critical infrastructure assets by:

Developing a broad security architecture, from cloud to control room, that limits gaps for adversaries;

Providing guidance on security leading practices and benchmarking your organization against industry peers;

Defining and prioritizing security initiatives in line with your risk appetite and budget;

Securing your networks, improving user access controls and hardening connected devices to help protect against cyber threats;

Enhancing your ability to protect, detect and respond to attacks with 24/7 PowerSOC monitoring and custom incident response playbooks.

PwC Canada's OT Security Lab

At PwC Canada, we don’t just help you identify and monitor your operating assets—we also help you test them in a secure sandbox environment to see how they stack up against the latest threats. Located adjacent to PwC’s Digital Resilience Center (DRC), our OT Security Lab can demonstrate:

Asset discovery and visibility: Try out OT monitoring tools with proof-of-concept testing, product comparisons and integrations with asset tracking products.

Detection and response: Test the integration of firewalls, intrusion detection and OT monitoring tools with SIEM software and SOC procedures.

Product technical review and testing: Conduct zero operational impact product and site acceptance testing and safe destructive testing (including OT penetration testing) in a near-production training environment.

Our OT Security Lab includes pre-configured environments with:

OT security monitoring tools

vendor-supplied HMIs and workstations

vendor-supplied programmable logic controllers (PLCs)

network firewalls

Active Directory
Microsoft Sentinel
