Top Security Features Every Colocation Cage Should Have

Without strong physical security, shared data centers are vulnerable to serious risks. A well-designed colocation cage is the last line of defense between your equipment and the outside world. We’ve helped secure thousands of data center spaces across the country. The best cages all share a few key features that go beyond just wire and steel.

Here are the security elements you should expect in any colocation cage worth investing in.

1. Heavy-Duty Steel Construction

If you’re putting your company’s infrastructure in someone else’s building, the cage protecting it must be rock solid. The foundation of any secure system is the material itself. We use 10-gauge wire welded into rigid steel frames with a 2" x 1" mesh pattern. Our Style 840 Wire Partition System is designed to resist cutting, prying, and tampering while maintaining visibility and airflow.

This isn't ornamental metalwork. It's a physical barrier designed to withstand 24/7 environments and enterprise-level security expectations.

2. Secure Access Control Points

No matter how strong the cage is, it’s only as secure as the entry points. Every colocation cage should include a locking system that fits your facility's access requirements. We offer hinged and sliding doors, which can be prepped for everything from padlocks to electronic strike plates and badge readers.

We often work with clients to integrate the cage’s entry systems with their building’s security infrastructure. This ensures that only authorized personnel can access the equipment inside and that access can be monitored and logged.

3. Ceiling Panels for Full Enclosure

In many data centers, the ceiling grid is open. Anyone with a ladder can bypass the cage without a secure top panel. WireCrafters provides welded wire mesh ceiling panels that match the structure and strength of the cage walls. These panels can be built to match varying heights and installed flush with or above the existing wall height, depending on what the facility allows.

We also account for sprinklers and other overhead fire suppression systems to maintain code compliance without sacrificing security.

4. Floor-to-Ceiling Fit

Gaps equal risk. An ideal colocation cage is custom-fitted to the room it's in. At WireCrafters, our modular systems allow us to build wall panels that fit precisely from floor to ceiling, even in rooms with uneven surfaces or awkward layouts. There are no open spaces along the floor or around the top, and there is no room to slip cables or tools through.

These small details matter when storing mission-critical hardware in a shared environment.

5. Tamper-Resistant Hardware

Every bolt and bracket on a cage should be selected with tamper resistance in mind. While not standard, we offer tamper-resistant hardware as an option designed to require specialized tools for removal and help prevent unauthorized access.

This feature alone can prevent downtime or worse, especially in environments with multiple tenants sharing the same data floor.

6. Expandable Design

Security today needs to work with your layout tomorrow. Whether you're planning a move, a rack expansion, or just keeping your options open, a cage that can adapt is a wise investment. Our modular partition systems can be expanded, relocated, or reconfigured without requiring complete teardown and rebuild.

It's a future-proof solution that doesn’t force you into long-term decisions based on short-term needs.

7. Visibility Without Vulnerability

Wire mesh is ideal for data center security because it allows visual inspections without requiring access. Cameras can monitor activity inside the cage, and facility staff can keep an eye on gear without breaching protocol.

If visual privacy is required, we offer sheet metal or polycarbonate panels that limit visibility while providing the same physical strength. Additionally, we offer solid vinyl screens that mount directly to wire mesh panels, adding privacy without compromising airflow or flexibility. In hybrid environments, mixing panel types to meet different zones of protection within the same cage is common.


When it comes to colocation cages, security is in the details.
