Startup cost: $500 - $5k

To start a side hustle in cybersecurity for IoT, costs range from $500 to $5,000. At the low end, this budget covers basic tools like software subscriptions and online training materials. On the high end, expenses include premium cybersecurity software, hardware for testing IoT devices, and professional certifications. Essential expenses include software subscriptions, training materials, and basic cybersecurity tools. Optional expenses might include advanced software tools and specialized training programs. Hidden fees could arise from ongoing software subscriptions or certification renewals. Costs can creep up as one commits due to the need for better tools and certifications. A serious approach would require a budget of $5,000 to cover all necessary tools, training, and certifications.
