Summary
Dennis Vesterlund is an Information Technology Security Specialist with 11 years of experience building and operating security monitoring and incident response solutions across public and private sector environments in Sweden. He brings deep hands-on expertise with IBM QRadar, Linux, Python, data visualization and automation, and has progressed from service desk roles to security architect responsibilities. At Atea he combined customer-facing workshops, platform integration and automation with incident analysis and secure data transfer architecture, and now applies that experience at Swedish Customs.

He pairs technical depth with an ability to onboard and mentor teams, and has a practical background that once ranged from chimney sweeping to managing his own company vehicle—evidence of a grounded, service-oriented work ethic.
