I’m Tom Tassi—GSEC (SW), USN (Ret), a dad, a grandpa, and a business owner. I run Absolute Computer Systems and spend my days helping people and organizations get and keep their technology secure, stable, and working the way it should. I value ownership, clear communication, and doing what I say I will do. I’m grateful for every day I get—and always willing to give a hand up to fellow vets and the community.

Absolute Computer Systems is a veteran-owned (SDVOSB) IT support and cybersecurity team serving Wisconsin businesses and families. We help reduce downtime, strengthen security, and keep systems running the way they should—so work gets done and stress stays low.
Our approach is practical and proactive: we fix the immediate problem, get to the root cause, and put guardrails in place to prevent repeat issues. That includes layered security (MFA, endpoint protection/EDR, email security, patching, monitoring), reliable backups and recovery planning, and clear guidance your team can actually follow.
We support day-to-day needs like computer and network troubleshooting, Wi-Fi reliability, Microsoft 365/email, new device setup, and remote + on-site help. For businesses, we also help establish sensible standards (documentation, access control, least privilege, backup verification) without turning your environment into a science project.
We’re proud to support fellow veterans and veteran-owned businesses whenever we can. If you’re tired of unreturned calls, vague answers, or recurring problems that never get resolved, you’ll appreciate our ownership mindset and plain-English communication.
