yes and no. It's normal to have software that safeguards company's intellectual property (how suitable this particular software is, I cannot speak). However, with that goal in mind, it's also normal for company to provide a dedicated, company-owned-and-managed hardware as well, such as laptop or phone. Demanding that employee or contractor use personal hardware but install monitoring software seems a lose-lose proposition for everybody - it will not necessarily achieve the level of control and safeguards that company desires, and it compromises the contractor's ability to safeguard their own and other clients' data. Depending on circumstances, my own approach would be to start with a friendly email indicating that you understand and support their goals, and propose that the best way to achieve them is to use customer provided and managed hardware.
