Introduction

Every system has a limit.
When you push your servers, networks, or applications beyond their capacity performance drops, downtime increases, and sometimes security fails.

That’s why ISO 27001 Control 5.29 Capacity Management focuses on planning, monitoring, and optimizing IT resources before problems occur.
It’s not just about keeping systems fast it’s about keeping them secure and reliable under pressure.

Why Capacity Management Matters

Imagine this:
Your company launches a new product, traffic surges, and your infrastructure can’t keep up.
To fix it fast, your team disables some safeguards “temporarily” and just like that, you’ve traded availability for vulnerability.

Control 5.29, from ISO/IEC 27002:2022 Section 5.29, ensures you never reach that point.
It’s an Organizational control that’s primarily preventive, supporting Confidentiality, Integrity, and Availability through the Protect and Detect cybersecurity concepts.
In simple terms: it’s about predicting demand, planning capacity, and preventing failures.

What This Control Involves

• Monitor System Utilization:
  Track usage of servers, storage, bandwidth, and applications to identify patterns and trends.

• Forecast Future Needs:
  Plan for growth — new users, services, and workloads — before capacity becomes a bottleneck.

• Implement Alerting:
  Set up thresholds and alerts when utilization nears critical levels.

• Maintain Security Controls:
  Ensure that increasing capacity doesn’t mean disabling protection mechanisms.

• Document and Review:
  Record performance metrics and revisit capacity plans regularly.

Common Pitfalls

• No performance monitoring or capacity planning at all

• Security configurations ignored to improve speed

• Reactive upgrades after incidents instead of proactive planning

• Poor communication between IT, DevOps, and management

Canadian Cyber’s Take

At Canadian Cyber, we help organizations balance performance, availability, and security by embedding capacity management into their ISO 27001 framework.
We design monitoring dashboards, review infrastructure scalability, and ensure your systems stay compliant even when workloads spike.

Because when capacity runs out, it’s not just performance that suffers security often follows.

Takeaway

Good capacity management isn’t about running faster  it’s about running smarter.
By staying proactive, you prevent downtime, maintain compliance, and protect data integrity even under stress.

ISO 27001 Control 5.29 helps you stay ahead of overload before it becomes a crisis.
