The data center industry is moving at a pace that’s hard to keep up with. Demand is outrunning supply, campuses are breaking ground faster than they’re finishing, and colocation operators are juggling tenant deadlines, certification timelines, and construction schedules all at once.
In that environment, a lot of facility planners fall into the same trap: build now, worry about compliance later. Get the suite up, get the tenant in, deal with the audit when it comes.
The problem is that compliance audits don’t grade on intent. They grade on what was actually built and whether it matches what was documented. By the time an auditor is walking your suite, the construction decisions are already locked in.
Strip away the technical controls, the policy documentation, and the incident response requirements, and each of these frameworks converges on the same three physical requirements: controlled and documented physical access, visual security that protects tenant anonymity, and verifiable infrastructure with documentation that matches what was actually installed.
A single well-designed physical suite can satisfy all four frameworks at once, or a single poorly-designed one can create audit findings across all four simultaneously. The choices you make during the buildout determine which outcome you are heading toward.
Of the four, HIPAA is the most physically specific and the framework where Starrco’s modular suite design has been most directly proven in colocation environments. If the physical infrastructure satisfies HIPAA’s requirements, the same design decisions usually apply across ISO 27001, SOC 2, and PCI-DSS as well.
For colocation operators, a wire cage design limits the business you can win. Prospective tenants under HIPAA, SOC 2, or PCI-DSS require solid-walled, physically secure suites. If your facility cannot offer that, those tenants go elsewhere. For compliance-driven tenants, solid walls are a baseline requirement.
In a multi-tenant environment, vendors, contractors, other tenants, and facility staff move through the floor regularly. Wire cages give every one of them a direct line of sight into the equipment inside: server brands, rack configurations, and enough contextual detail to identify whose data is being processed and who it belongs to. What looks like a simple infrastructure choice on the construction side creates a demonstrable security gap on the compliance side.
Under HIPAA’s Security Rule physical safeguards (45 CFR § 164.310), that visibility is a documented compliance finding. For SOC 2 and PCI-DSS, the standard is the same: data environments must be isolated from unauthorized observation. Wire cages fail that test. A solid-walled suite passes it and positions your facility to compete for the compliance-driven tenants driving growth in the colocation market.
Believe it or not, the door frame is where most compliance-driven buildouts go sideways.
Compliant colocation suites require keypads, card readers, door controllers, wiring runs, and sometimes biometric hardware, all with specific mounting and clearance requirements that go well beyond a standard commercial door frame. Most modular wall systems were not designed with this in mind. So field crews often have to modify the frame to make it work. The installation functions, but the as-built drawings now reflect a deviation from the documented spec, there are chances of this being flagged.
Starrco addresses this by handling door frame prep at the factory before the system ships. Hardware clearances, framing dimensions, and mounting accommodation are built in during manufacturing rather than worked out on-site. Factory prep currently covers the significant majority of that work, with ongoing product development aimed at eliminating field modification entirely. When the system arrives, the frame is ready for the hardware, and the as-built documentation stays clean.
Since the same physical infrastructure decisions show up across all four frameworks, it is worth understanding each one.
Addresses physical and environmental security through Annex A, specifically through controls requiring secure areas, physical entry controls, and protection of equipment against physical threats. The documentation requirements built into the ISO audit process make clean as-built drawings and factory-prepped installations directly relevant, not just the physical hardware itself.
Addresses physical access controls through the Common Criteria, requiring that access to the physical environment be restricted, monitored, and documented. Solid walls and factory-prepped access control hardware satisfy the physical isolation requirements. Wire cages create the monitoring problem that solid walls eliminate.
(45 CFR § 164.310) covers facility access controls, workstation use and security, and device and media controls under the Security Rule’s physical safeguards. Of the four frameworks, HIPAA is the most specific in its physical requirements and the most directly addressed by solid-walled modular suite design with proper access control infrastructure. It has also been the compliance driver behind Starrco’s strongest real-world colocation deployments.
(Requirement 9) requires restricting and monitoring physical access to system components and cardholder data. The visual security that solid walls provide, combined with hardware-ready access control infrastructure and clean documentation, addresses Requirement 9 directly in a way wire cages simply cannot.
Before selecting a modular wall system supplier for a compliance-driven buildout, three questions are worth asking directly:
Starrco has been building modular systems for environments with strict physical requirements for 60 years. In colocation data centers specifically, the product design reflects what happens during compliance audits: the details of the physical installation become part of the evidentiary record. Getting those details right starts at the factory.
