Window Zero
EXPOSURE GAPWindow Zero is the time the breach stayed in the open before anyone said so — the gap between when the attack was first discovered on the operator's leak site (t1) and when it was publicly disclosed (t2). The wider this window, the longer victims, staff and customers were exposed with no warning.
Attack Summary
Since 1964, Guaranteed Supply Company has grown to 15 locations. Along the way, we have expanded to feature product lines focused on Concrete Materials, Thermal and Moisture Protection, EIFS/Stucco Products and more. As well as building the largest, independently owned, custom rebar fabrication company in the Carolinas - JMS Rebar. Throughout this journey, Guaranteed Supply Company has kept the same attention to personal care and quality materials that started it all.
