Simplify's Take

What believers are saying

  • Texas operations grew by acquisition: Marksman bought Austin's Priebe Security Services in January 2026, adding over 450 employees.
  • Frontline hires reach leadership: Marksman's Las Vegas vice president started as a guard in 2013, then earned five promotions.
  • Part-timers earn paid time off: Marksman's Buckhead, Atlanta officer posting grants eight hours for every 100 worked.

What critics are saying

  • Officer pay is modest: Marksman's part-time Mesquite, Texas retail officer posting pays $15.84 an hour.
  • Flex schedules are unpredictable: Marksman's Plano, Texas flex officer posting requires answering assignments with little to no notice.
  • Private equity backs the parent: Quad-C, a middle-market buyout firm, supports Marksman Titan Security Group.

What makes Marksman Security unique

  • Some teams fight fires: Marksman hires firefighters for Toyota's battery plant fire rescue team in Liberty, North Carolina.
  • Meta is a data center client: a Marksman vice president leads the security partnership supporting Meta's global portfolio.
  • Security systems work sits with a sister brand: Chicago-based Titan, part of Marksman's parent group, hires the installation technicians.
