What You’ll Learn
Personal phones are already part of how most companies work, whatever the policy says. This guide, built on Verizon’s 2025 Mobile Security Index, Palo Alto Networks’ 2025 device research and NIST guidance, compares the four device models a 200 to 2,000-person company can use: company-owned, BYOD with full management, BYOD with app protection only, and a managed workspace. It shows which model fits which group of people, what each costs per person, the controls that apply to all of them, what the written policy has to say, and six questions to ask a device management provider.
