Mark Allers

Mark is the VP of Business Development at Cimcor and is responsible for driving the strategic focus and alignment with industry initiatives and partnerships. Mark has held executive management positions in both security and IT Service Management companies. His primary emphasis has been on software security and enterprise management for companies including Tripwire, CyberSafe, Symbium, SignaCert, TriStrata, and New Net Technologies, and he has served on several advisory boards. He is often invited to give keynote presentations on the topic of integrity monitoring, Zero Trust, and compliance. Most recently, he has helped author and assemble the controls for the Department of Homeland Security’s Zero Trust Framework.

Mark was also responsible for establishing a strategic partnership between Tripwire and Lloyds of London, where he launched the world's first cyber-insurance policy called e-Comprehensive. e-Comprehensive was designed to shield a company from loss due to unauthorized and malicious activity to corporate information systems. Lloyds provided a 10% premium discount to their e-Comprehensive clients when Tripwire technology and controls were deployed correctly.
