US Signal Data Centers

Compliance Built Into Every Facility

Data compliance isn’t an add-on at US Signal — it’s audited. Every facility operates under a formal Governance, Risk, and Compliance (GRC) program overseen by our CISO, with third-party audits and attestations conducted annually for:

• SOC 1, Type 2
• SOC 2, Type 2
• HIPAA / HITECH
• PCI DSS
• GDPR
• CJIS

Our internal audit team, staffed by CISA-certified professionals, uses the ISO-19011 framework to plan, conduct, and report on audits year-round — separate from and in addition to third-party attestations. If your organization requires a Business Associate Agreement (BAA) as part of a HIPAA-compliant deployment, we execute one directly, and extend the same requirement to any third party involved in delivering your compliant services.

Physical Security at Every Location

Every US Signal data center — regardless of size or market — is built around the same layered physical security model:

• Biometric access control using iris scan or access card credentials depending on location — with mantrap entry requiring scan-in and scan-out
• Secure vestibules at every entry point, adding a controlled buffer before the data center floor
• 24/7/365 video surveillance, with footage retained a minimum of 90 days and stored off-site
• Physical access logs retained for seven years
• 6-foot perimeter fencing, pylons, and bollards protecting entrances and generator areas
• Segregated shipping and loading areas, kept separate from the data center floor
• Mandatory visitor sign-in, badging, and escort for the duration of any site visit

Two of our facilities — Grand Rapids (MI01) and Detroit Metro (MI03) — go a step further with dedicated 24/7 on-site security personnel, in addition to round-the-clock monitoring by our Technical Operations Center (TOC). Every other location is continuously monitored by the same TOC team, with the same alarm coverage for HVAC, water flow, power, humidity, and generator status.

Technical Safeguards

Protecting what’s inside the building matters as much as protecting the building itself. Our technical safeguards follow a defense-in-depth model:

• Routine system hardening and vulnerability assessments, backed by structured patch management
• Identity and access management with mandatory multi-factor authentication (MFA) on all administrator accounts
• Conditional access and VPN-based remote access controls
• Perimeter and host-based firewalls, plus web application firewalls (WAFs)
• Encrypted, access-controlled backups tested for recovery readiness
• 24/7 monitoring by our Security Operations Center (SOC), using centrally managed EDR/XDR platforms including Microsoft Defender, SentinelOne, and CrowdStrike

Power & Cooling You Can Rely On

Every facility is built on redundant power and cooling, engineered to keep your infrastructure running through any disruption:

• Backup power through a combination of generators, UPS battery systems, and DC power plants
• Priority refueling contracts to sustain generator runtime during extended outages
• Quarterly preventative maintenance and semi-annual load-bank testing on all generators
• Minimum N+1 redundancy on HVAC systems facility-wide

Exact generator, UPS, and cooling capacity vary by location and are detailed on each facility’s individual page.

A Network Built for Performance

US Signal’s data centers are connected by a private, multi-state fiber network built on a meshed MPLS core (Cisco ASR 9000) and DWDM transport supporting waves up to 100 GB and beyond. Our peering program spans more than 140 companies, with direct, on-net presence at Equinix Ethernet Exchanges in Chicago, Detroit, Ohio, and Ashburn, VA — giving customers one-hop access to many of the internet’s most heavily used services and cloud platforms.
