Managed IT Services in Fresno, CA
Managed IT Services and IT Support for Fresno Businesses
Managed IT services replace the break-fix model, where you call someone after a problem stops work, with ongoing, proactive management. Your systems are monitored around the clock, maintenance happens on a schedule, and your staff has a help desk to call when something goes wrong.
Managed IT is usually the right fit when:
- Your business has grown past the point where one employee or an occasional contractor can keep up with IT
- Downtime, slow networks, or recurring problems are costing your team hours every week
- You don’t have a clear picture of your backups, security, or which devices are on your network
- You want predictable IT costs instead of surprise repair bills
- You need IT support that can also come on site when a problem can’t be solved remotely

Cybersecurity for Fresno Businesses
Cybersecurity is part of every managed IT relationship, not an add-on. Small and midsize businesses in Fresno face the same threats as larger companies, including phishing, ransomware, and compromised passwords, usually with fewer resources to respond.
Our approach focuses on the protections that matter most for a growing business:
- Firewalls and intrusion prevention to block threats at the edge of your network
- Continuous monitoring and alerts so suspicious activity gets attention quickly
- Secure business WiFi, designed and configured to keep guest and business traffic separate
- Backup and recovery planning, so a hardware failure or ransomware incident doesn’t mean lost data
- Guidance for your team on the everyday habits that prevent most incidents

IT Consulting and Technology Planning in Fresno
Not every IT need is a monthly service. Our IT consulting helps Fresno businesses make larger technology decisions with a clear plan:
- IT and network assessments that document what you have, what’s at risk, and what should change first
- Network design for new offices, expansions, and relocations
- Cloud migration planning to decide what belongs in the cloud and what should stay on site
- Technology planning that ties IT upgrades to your budget and growth plans

Remote and On-Site IT Support
Most IT issues can be solved remotely, and remote support is usually the fastest way to get your staff back to work. Some problems, like a failed switch, a new workstation setup, or a wiring issue, need someone on site. As a Fresno-based company, Sebastian can do both.

Why Fresno Businesses Choose Sebastian for Managed IT
- Local since 1946. Sebastian began as Kerman Telephone Co. in 1946 and is headquartered in Fresno at 7600 N Palm Ave. Our team lives and works in the communities we support.
- One team from the wall jack to the cloud. Most IT providers stop at the server and the software. Sebastian also installs structured cabling and low voltage systems, commercial electrical, access control and security, and commercial AV. When a network problem turns out to be a cabling or power problem, you don’t need to call a second company.
- Telecommunications roots. Decades of running networks for homes and businesses across California shape how we design and support business networks.

Sebastian was able to determine the issues and make recommendations for solving those problems. We would most definitely recommend Sebastian to other colleges or businesses because of their well-rounded yet technical knowledge base, outstanding customer service, and continuing evolution of technology awareness.
Sebastian is one of the best companies I have worked with from a customer standpoint.
Sebastian is a well-recognized and highly recommended local company and a leader in the technology industry. Sebastian employees were all very gracious, friendly and technically competent. They were very quick to address our concerns.
Sebastian did a great job and I would use them again to run or fix fiber optic cables. Their team was very professional and did very clean work.
Karlene was a pleasure to work with and kept me updated during the entire process until the job was complete. I’ve worked with others in this industry and none compare to her experience or her professionalism!!
We are extremely appreciative and impressed not only with the work Sebastian has completed at Fresno State so far this year, but also the flexibility and commitment. We continually hear great things about Sebastian and are very excited to work with us on a new campus wide Access Point project.
