ENSCO, Inc.

ENSCO, Inc. has been operating in defense and national security engineering since 1969. The privately held firm, headquartered in Vienna, Virginia, employs over 750 people across offices in California, Colorado, Florida, New Mexico, New York, Pennsylvania, and Virginia. Its client base spans government and private industry worldwide, with deep roots in aerospace and surface transportation alongside cybersecurity. The company's cybersecurity practice sits inside a broader systems engineering and integration operation. Threat models here skew toward the kinds of targets that matter at the national security level - critical infrastructure, aerospace systems, and the data pipelines that connect them. ENSCO holds CMMC Level 2 certification , meaning it has implemented the 110 security controls from NIST SP 800-171 required to handle controlled unclassified information. That's table stakes for defense contracting, but it also signals a security posture baked into operations, not bolted on after the fact. Work spans advanced technology services across multiple domains: systems engineering, integration, and applied cybersecurity for customers who operate in high-consequence environments. The company emphasizes a collaborative, team-oriented structure - less siloed specialist, more integrated engineering shop where cybersecurity professionals work alongside systems engineers and domain experts across aerospace, national security, and transportation verticals.
