Invisicade Crisis Shield CS\-650 combines exceptional engineering with a commitment to glazing security ensuring that facilities remain secure, efficient, and compliant with the latest standards\.\ \In response to rising retail crime, forced entry incidents, and mass casualty events involving glazing, applied security glazing retrofits needed to have increasing levels of break strength and other physical properties to meet increasing threat levels and testing standards, Crisis Shield CS\-650, a high\-performance security laminate developed by a globally recognized manufacturer, was introduced as the thickest and strongest such manufactured product to meet those needs\. Initially marketed under a different name, it has been installed on over 700,000 sqft of glazing in U\.S\. education, retail, and commercial sectors\. After the original partnership ended, Viscera Brands secured exclusive U\.S\. rights, rebranded it as Crisis Shield CS\-650, and conducted rigorous testing to showcase its capabilities\. Today, it is distributed nationwide through NGS, the nation's leading retrofit glazing security contractor\.\ \
