Business in Ventura County
Ventura County sits just west of Los Angeles County along the 101 and the 118, and its business life is spread across several distinct cities rather than one downtown. The Conejo Valley, centered on Thousand Oaks and Westlake Village, holds biotech, corporate headquarters and professional firms. Simi Valley has manufacturing and defense suppliers. Camarillo, Oxnard and Port Hueneme add agriculture, logistics and the Navy's presence at Naval Base Ventura County.
Wildfire is part of business planning here. The Thomas Fire in 2017, the Woolsey Fire in 2018 and the Mountain Fire near Camarillo in 2024 all closed roads and businesses, and in high fire weather Southern California Edison can cut power through Public Safety Power Shutoffs. Ventura County businesses benefit more than most from cloud-based files, a second internet connection and a business continuity plan that works from home.
Thousand Oaks
Thousand Oaks is the largest city in the Conejo Valley and the anchor of its business community. Amgen has its headquarters here, and life-science suppliers, medical groups and professional firms have grown up around it. Los Robles Regional Medical Center and a dense network of physician and dental practices make healthcare a major part of the local economy, and business parks line the 101 and Rancho Conejo Boulevard in Newbury Park.
Life-science suppliers often face customer security audits and strict record-keeping, and medical practices work under HIPAA. For both, the core is HIPAA compliance or equivalent controls, access that is reviewed and documented, and backups that are tested by restoring them.
Westlake Village
Westlake Village straddles the county line: the incorporated city is in Los Angeles County, while the adjoining Westlake neighborhoods of Thousand Oaks are in Ventura County. Office parks along Westlake Boulevard, Townsgate Road and Agoura Road hold corporate headquarters, wealth management and financial firms, insurance agencies and law practices.
For these firms, confidentiality and fraud prevention come first: email security against wire fraud and impersonation, multi-factor sign-in everywhere, and the written security programs the FTC Safeguards Rule and SEC rules expect from financial firms.
Simi Valley
Simi Valley, along the 118 at the county's eastern edge, has one of Ventura County's larger concentrations of manufacturing, including aerospace, defense and electronics suppliers in industrial and business parks near the freeway. Many of its residents commute to jobs in the San Fernando Valley, which makes secure remote work a practical need for local employers.
Defense suppliers here face NIST SP 800-171 and CMMC terms in their contracts, and plant networks need to be kept apart from business systems, with older machines isolated. Our manufacturing page covers each step.
Camarillo
Camarillo, further west on the 101, has grown into a business hub with business parks near Camarillo Airport and along the freeway, technology and manufacturing companies, and firms that serve the farms and logistics operations of the Oxnard Plain. California State University Channel Islands is just south of the city, and Naval Base Ventura County is nearby.
Businesses here often run across several sites, such as a headquarters in Camarillo, a warehouse or cooling facility in Oxnard and field operations elsewhere. Secure connections between sites, managed devices for field staff, quick onboarding and offboarding for seasonal workers, and reliable backups matter most.
