About Portolan Networks
Portolan Networks LLC is a managed IT and cybersecurity company based in Sarasota, Florida. Pat Midzio founded it in 2020, and we support businesses across Sarasota, Manatee and Charlotte counties with managed and co-managed IT, cybersecurity, Microsoft 365, backup, business phones and internet connectivity.
Why “Portolan”?
Portolan charts were the sailing charts navigators relied on from the late Middle Ages: practical maps built from real voyages, marking coastlines, harbors and hazards so a crew could reach port safely. That’s the job we want to do for your business: know the terrain, spot the hazards before you hit them, and help you plan the route.
How We Work
- Security is part of every plan. Every Managed IT plan includes 24/7 monitored EDR, DNS filtering and privileged access management. It isn’t an upsell. See what’s included.
- Plain language. We explain what we recommend, why, and what it costs before we do it.
- Named tools. We tell you which products protect your business: Huntress, DNSFilter, Proofpoint, Keeper and others.
- Planning, not just fixing. Technology roadmaps, IT budgets and hardware lifecycle plans keep surprises to a minimum. IT consulting.
- A small team on purpose. With over 70 years of combined IT experience, you work with people who know your setup.
Who We Work With
Most of our clients are small and midsize businesses that want their IT handled for them, or that have their own IT person and need a partner behind them. Over his career, Pat has supported organizations from small offices to a school district with about 40,000 computers, in manufacturing, construction, education, legal, finance, golf clubs and membership organizations.
Where We Work
We’re based in Sarasota and serve all of Sarasota, Manatee and Charlotte counties, from Bradenton, Palmetto and Lakewood Ranch to Venice, North Port, Englewood, Port Charlotte and Punta Gorda. Most support happens remotely. We come on site when the work needs hands on hardware.
