In cities where the security workforce is increasingly costly and aging, hiring and ensuring adequate security is becoming a serious challenge.

Security robot-as-a-service (RaaS) enables companies and security contractors to fill gaps in their security coverage and yet avoid having to invest in high, upfront capital expenditure.
