When high profile celebrities, athletes, rock stars and other prominent notables come to Boston, it’s important they have an incredible time in our city but remain safe and secure while doing so. That’s why they call RSIG Security in advance of their visit. Event security and private entertainment industry protection are the company’s specialties. To find out what it’s like to travel on the road with a rock star, we chatted recently with RSIG owner Tim Mazzie. Mazzie, who got his start in the security business while in college, quickly realized there was an opportunity in the private sector for personal security. “When we are asked to supply executive protection for a band, we assign one person to each band member, who stays within five feet of that person at all times,” Mazzie said. “At concerts, we make sure that fans don’t get up on stage and ensure that there is someone always around the celebrity.”
