With benefits such as micro-segmentation of cyber attacks, security zoning, and immense scalability, NSVs are hard to ignore.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">These virtual firewalls can be found in public, private, and hybrid cloud environments and stack up quite well against traditional firewall applications. Aside from simple efficiencies and general ease of use, the mix of virtual security and cloud technology has substantial upside for any modern business.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For this article, you\u2019re going to get a brief comparison between a security virtual appliance and the traditional approach of firewall hardware.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6b04381 elementor-widget elementor-widget-heading\" data-id=\"6b04381\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Stepping Into Virtual Firewall Security<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6dd3192 elementor-widget elementor-widget-text-editor\" data-id=\"6dd3192\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">While traditional firewall hardware will still have its place for quite some time, integrations with virtual solutions are becoming increasingly popular.
