Data centres carry a security burden that few other buildings match. A single hall can hold servers for dozens of tenants, each with its own compliance obligations, so the physical controls have to hold up to outside audit and internal scrutiny at the same time. For Canadian integrators and consultants working colocation and enterprise sites, the job is less about one clever product and more about layers that reinforce each other from the fence line to the cabinet door.
Layered physical access
The working model is concentric. You control the site perimeter, then the building envelope, then the data hall, then the individual cabinet. Each boundary uses its own access control reader group and its own permission set, so a technician cleared for one hall cannot badge into another. Keep the credential technology consistent across layers where you can, and document which reader belongs to which zone before commissioning. When a client asks how to compare products, how to choose an access control platform walks through the criteria that matter at this scale.
Mantraps and cabinet-level control
Anti-tailgating is where most access designs succeed or fail. Mantraps, sometimes specified as interlocking door pairs, force one person through at a time and refuse the second door until the first is secured. At the cabinet, electronic locks with per-door audit logs record who opened which rack and when, which is the granularity auditors expect. Pair those logs with the access events from the hall so a reviewer can reconstruct a full path.
TIA-942 and infrastructure
ANSI/TIA-942 defines data centre infrastructure and the tier ratings that describe redundancy and availability. It is not only a cabling document. It sets expectations for space, power, cooling, and the security provisions that sit alongside them, which makes it a useful common reference when you are coordinating with the facility and mechanical teams.
SOC 2 and audit trails
SOC 2 Type II reports are the trust evidence colocation and cloud providers hand to their customers. The security controls you install feed those reports directly. Video retention windows and access audit trails are the records auditors sample, so set retention to match the client’s stated policy and confirm the logs survive a hardware swap.
Video, cabling, and power
The video surveillance coverage, the structured cabling that carries it, the datacom backbone, and the power feeds are one physical build, not four projects. Plan the pathways together, label everything, and hand over a record that the next contractor can read.
