What Texas Security General Insurance Agency does

Texas Security General Insurance Agency (TSGA) is a Texas-domiciled Managing General Agency founded in 1995 in San Antonio, operating as a subsidiary of Brown & Brown (the 5th largest insurance intermediary in the United States). The company underwrites and distributes both personal lines (Homeowners, Dwelling Fire, Mobile Homes, Coastal property) and commercial lines (Artisan Contractors, Property, Inland Marine, General Liability, Directors & Officers, Professional Risks) exclusively to independent insurance agents across Texas, supported by three offices (San Antonio headquarters, Dallas/Plano, Tyler) and a regional territory manager structure. The company's technology stack consists of three proprietary rating platforms — ISi Rater for personal lines, TARGET Rater for commercial lines, and The Bridge (partnered with Bridge Specialty Group) for HO3/DP3 homeowners quoting — through which agents quote, bind, and place coverage with carrier partners including Tower Hill Specialty, Aegis, USLI, and Atlantic Casualty.

TSGA's business model is the standard MGA construct: it earns commission income on premiums placed with carrier partners, augmented by two wholly owned subsidiaries — TSG Premium Finance, which provides premium financing to policyholders and generates interest income, and TSG Claims Management, founded in 2006, which provides third-party claims administration services. The go-to-market is wholesale distribution through independent agents rather than direct-to-consumer or captive-agent channels, giving TSGA a distributed volume model that mitigates individual-producer concentration while creating dependency on a small named set of carrier appointments. The company employs roughly 100+ staff and has scaled to approximately $112 million in net written premium. Recent senior leadership additions — Greg Riedel (EVP/Managing Director, July 2025, ex-USAA) and Hector Collazo (SVP P&C, 2023, ex-Travelers) — indicate a strategic refresh oriented toward deepening carrier relationships and expanding underwriting capacity within the Texas market.
