Comcast Business

Comcast Business is the enterprise division of Comcast Corporation, the nation's largest cable company, publicly traded on NASDAQ (CMCSA) and headquartered in Philadelphia, Pennsylvania. With approximately 186,000 employees and a connectivity portfolio that spans broadband, fiber, SASE, SD-WAN, and cloud networking, Comcast Business has transformed from a regional cable provider into a credible global enterprise connectivity contender — largely through the acquisition of Masergy, one of the enterprise SD-WAN and security market's most respected names.

Network Ownership and Last-Mile Control

A critical differentiator for Comcast Business in the enterprise connectivity market is its owned network and last-mile infrastructure. Covering approximately 67%+ of the domestic market, Comcast Business can deliver broadband and fiber without relying on third-party local loops in its footprint — reducing installation complexity, improving SLA accountability, and eliminating the finger-pointing that plagues multi-vendor connectivity deployments. Outside the Comcast footprint, the company leverages its aggregator capability and the Masergy-inherited global network to extend reach.

Connectivity Portfolio

Top products include Broadband Internet, Ethernet DIA (both EDI and SLA-based DIA options), and SASE/SD-WAN — a combination that positions Comcast Business for both connectivity-first and security-first enterprise buying decisions. Public data services span the full range: 4G/LTE/5G, asymmetrical and symmetrical broadband, DIA, fixed wireless, and satellite (high and low earth orbit). Private networking options include Dark Fiber (ICB), Private LTE/5G, MPLS, VPLS, and point-to-point private lines. DDoS mitigation is included.

SD-WAN and SASE Depth

The Masergy acquisition gave Comcast Business a sophisticated SD-WAN and SASE capability. SD-WAN platform support extends across Cisco Meraki, Cisco SD-WAN, Fortinet, HPE Aruba, VeloCloud, and Versa Networks — one of the broadest platform partnerships in this analysis.

Global Footprint

Comcast Business has sold connectivity services into 100+ countries with 50+ global POPs, and supports billing in seven currencies: AUD, CAD, EUR, GBP, NZD, SGD, and USD — a strong foundation for multinational enterprise deployments.
