Profile bio

About John Harrison

I am a proven leader that has operated from the trenches in Afghanistan, Iraq, and now in cyber security operations centers preventing, detecting, and mitigating all forms of malicious activity. I am passionate of applying battlefield testing and proven artificial intelligence methods and other advance analytical capabilities to the cybersecurity detection and response problems many companies and agencies face today.Over the past 15 years I have helped the Federal Government build and deploy analytical and response capabilities for problem-sets such as counterterrorism financing, financial fraud and money laundering, computer forensic analysis, and cybersecurity operations. My focus and strength is communicating in business terms that leadership understands and building strategies that take a “small-win” iterative approach to reaching a desired maturity level. Though, what motivates me the most is to provide assurance and comfort to customers and leaders that they are protected and in the event a cybersecurity breach does occur they are well-prepared to respond quickly with focus and determination.Specialties: Intrusion Detection, All-source and Cyber Threat Analysis, Cloud/On-premise/Hybrid Security Architecture Design, Vulnerability and Compliance Assessments, Incident Response Planning and Automation, Insider Threat Detection and InvestigationsPlease connect and contact me at john.harrison@criterion-sys.com if I can be of any assistance.
