The OT environment—whether it’s a warehouse, factory, or plant—requires a unique approach to cybersecurity. Unlike traditional IT offices, OT systems have different priorities and risks. Establishing strong managed cybersecurity services for these environments calls for a specialized strategy.
At Summer Digital, we provide cybersecurity consulting services and cybersecurity managed services that help industrial organizations navigate all four stages of OT security maturity.
Stage 1: Getting Started
This is the foundation for any successful cyber security managed services plan:
- Conduct a full asset inventory.
Know every detail of your environment: hardware, software, OS, ownership, usage, and purpose. - Control physical access.
Without a secure physical environment, even the best cyber solutions won’t protect you. - Get executive buy-in.
Strong cybersecurity advisory services need backing from leadership to be effective.
Draft a resource plan with responsibilities clearly defined.
A RACI diagram can help outline roles. Since many stakeholders outside of IT (like production, health & safety, and unions) are involved, clarity is key.
Stage 2: Managed Security
This is where real protection begins. Our managed cybersecurity experts help you implement foundational controls:
➡️ Patch management
Regular patching is essential. If a system can’t be patched, document it and mitigate the risk.
➡️ Application whitelisting
Only approved applications should run—an essential tactic in cyber security consulting services.
➡️ Isolate vulnerable networks
Don’t forget to include your WiFi network. It can be hard in urban centers like Toronto that are not manufacturing hubs to find OT specialists who can create robust, secure industrial networks, segmented from non-industrial traffic.
➡️ Establish a dedicated OT security team
OT isn’t office IT. You need cybersecurity specialists who also understand the production floor.
➡️ Implement robust logging
You can’t analyze what you never recorded. Logging is a core function in cybersecurity managed services.
Stage 3: Proactive Security
Industrial organizations in Toronto and across North America are moving toward proactive, intelligent security with cyber security managed services like ours:
- Develop incident response plans
And test them regularly through exercises. - Conduct regular penetration testing
At Summer Digital, we recommend ongoing pen testing as a service. Static testing isn’t enough anymore. - Implement active threat detection and response
Modern cybersecurity services in Toronto use automated, smart platforms that replace legacy SIEM-SOAR systems. - Adopt a zero-trust model
Especially for OT systems where assumptions of trust are risky.
Use standards like IEC 62443 or NIST ICS Security Guide
Regular auditing against these standards supports your overall cybersecurity advisory services approach.
Stage 4: Secure by Design
This is the long-term vision of managed cybersecurity—making security intrinsic to every component: At this stage, you have a trained team, documented plans, organizational buy-in, and basic controls have already been implemented. Now, you want to build an environment which is inherently and intentionally secure, rather than an insecure environment with a series of controls pasted onto it.
- Defense in depth
Layered defenses help compensate for inevitable OT-specific security limitations. - Embrace open standards
Avoid vendor lock-in. OT hardware often outlasts vendors, so flexibility is key. - Prefer products that are secure by default and fail-safe
Just like you wouldn’t accept machinery that fails into an unsafe state, you shouldn’t accept software that fails in an insecure way.
Own your software
Reject black-box solutions with zero transparency. If it’s in your OT environment, you must ensure it meets your managed cybersecurity services standards.
