NIST 800-171 Rev 3 raises the bar by requiring a <strong>&#8220;deny-all, allow-by-exception&#8221;<\/strong> software execution policy. In other words, unless a piece of software is explicitly allowed, it shouldn\u2019t run.<\/p>\n\n\n\n<p>Application allowlisting enforces this principle by flipping the traditional cybersecurity model on its head\u2014blocking all unauthorized applications instead of reactively scanning for known threats like antivirus software does.<\/p>\n\n\n\n<p>But while the concept sounds simple, execution can be tricky\u2014especially for small businesses with limited IT staff.<\/p>\n\n\n\n<p>That\u2019s where this webinar comes in.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">What You\u2019ll Learn<\/h2>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">A Practical Understanding of Application Allowlisting<\/h4>\n\n\n\n<p>Totem Technologies will break down how allowlisting works, why it matters for compliance, and how it significantly reduces your organization\u2019s exposure to ransomware, malware, and insider threats.<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">Insights from Industry Leaders<\/h4>\n\n\n\n<p>You\u2019ll hear from:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Adam Austin<\/strong>, Owner, Totem Technologies \u2013 CMMC expert specializing in DoD contractor readiness.<\/li>\n\n\n\n<li><strong>Corey Munson<\/strong>, VP, PC Matic \u2013 Pioneer of automated allowlisting technology tailored to simplify compliance.<\/li>\n\n\n\n<li><strong>Willie Crenshaw<\/strong>, CEO, CyberPrime \u2013 Architect of NASA\u2019s Continuous Diagnostics and Mitigation program.<\/li>\n<\/ul>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">The PC Matic Advantage<\/h4>\n\n\n\n<p>Discover how PC Matic\u2019s automated allowlisting solution simplifies setup and maintenance\u2014making it achievable for even the smallest IT teams.
