Lumen

Lumen Technologies (NYSE: LUMN) is a publicly traded Tier 1 carrier headquartered in Monroe, Louisiana, delivering enterprise connectivity, cloud networking, security, and communication services globally. The company's connectivity infrastructure is built on the foundation of the Level3 Communications fiber network — one of the world's most extensive subsea and terrestrial fiber backbones — acquired through CenturyLink's 2017 merger that created Lumen.

Network Scale and Reach

Lumen's global connectivity infrastructure includes 40+ Network Operations Centers (NOCs) and hundreds of Points of Presence (POPs) across all global regions — Africa, Asia-Pacific, Europe, Latin America, and the Middle East. International business represents $4B annually, with connectivity sold into 100+ countries and billing currencies available on ICB.

Connectivity Portfolio

Top connectivity products include Internet (dedicated and broadband), SD-WAN, and SIP Trunking — a combination purpose-built for enterprises that need both network transport and voice modernization. Public data services span 4G/LTE/5G, broadband, DIA, fixed wireless, and satellite (LEO). Private networking includes Private LTE/5G, MPLS, VPLS, and point-to-point private lines. DDoS mitigation is available.

Cloud connectivity is delivered directly and via 3rd party to AWS, Azure, GCP, IBM, and Oracle on a global basis. SD-WAN platform support covers Cisco Meraki, Cisco SD-WAN, Fortinet, VeloCloud, and Versa Networks.

Security and Intelligence

The Black Lotus Labs acquisition brought Lumen a dedicated threat intelligence and DDoS mitigation capability that is integrated into its connectivity infrastructure — an increasingly important differentiator for enterprises seeking security-aware networks rather than overlay solutions.

Strategic Acquisitions

Key acquisitions include Level3 (backbone fiber), Savvis (data centers), ElasticBox (cloud automation), Cognilytics (analytics), DataGardens (disaster recovery), SEAL Consulting, Tier3, and Black Lotus Labs — each deepening Lumen's ability to deliver connectivity, cloud, and security as an integrated solution.
