Strategically designed, implemented, and manage a robust and secure IT infrastructure that provides essential services for a Town of over 30,000 residents. Hardened the security footing, resulting in a proven shield against ransomware and hacking and a consistent A-rating in our yearly penetration testing.o Perform ongoing Risk Management assessments that include areas of highest vulnerability, and annually provide a roadmap, strategic plan and cost analysis of mitigating or accepting each risk. This has saved approximately 100,000 per year and has improved the security footing of the Town and all facilities including our firehall, water treatment and operations buildings.o Implemented and administer a SIEM (AlienVault) that securely gathers system logs and provides real-time monitoring in the event of detected anomalies, providing greater insight and faster response to suspicious activity within the network.o Organized, manage, and assist in a yearly penetration test conducted by an independent third party (ION Systems), allowing for an unbiased review while adding layers of protection after identifying security deficiencies.o Implemented and administer an AI based endpoint protection platform (Blackberry Cylance Protect) with custom policies to restrict PowerShell, scripting, RDP, USB devices, resulting in zero security incidents since deployment.o Implemented an HA Fortinet Firewall with intrusion detection and monitoring, including tight security policies and isolated VLAN’s. Enabled FortiAnalyzer to gather all incoming and outgoing logs. This has provided industry leading protection, allowing Geolocation of all attempted threat vectors and quick action to stop malicious activity.o Designed a training program with monthly simulated phishing campaigns using KnowBe4, to score each user, assess security awareness and provide additional training as needed. This has strengthened the weakest security link in our infrastructure.
