IT Services & Cybersecurity in Hawaii
Hawaii businesses work across islands that each run their own power grid, linked by undersea cables and inter-island freight. NetSys is an IT company that gives organizations from Honolulu to Hilo, Kahului and Lihue managed IT, help desk support, cybersecurity and consulting, delivered remotely from Brooklyn on month-to-month agreements.
The short answer
NetSys provides managed IT, help desk support, cybersecurity and IT consulting to organizations across Hawaii, entirely remotely. Engineers in Brooklyn run Microsoft 365, Intune, ThreatDown managed detection and response, firewalls, Wi-Fi and backups for offices on any island, and handle the mainland vendors behind your software. NetSys does not send engineers on site anywhere in Hawaii; laptops ship enrolled in Windows Autopilot, and local staff or contractors connect other equipment. The help desk is staffed 4 a.m. to 11 p.m. Eastern time, closing in the late afternoon or early evening Hawaii time, and monitoring runs 24/7. Managed IT is priced per user per month after an assessment.
- One office, in Brooklyn, NY; every Hawaii island is served remotely, and NetSys sends no engineers on site in the state
- Neighbor-island offices share one Microsoft 365 tenant, one Intune policy set and one firewall dashboard with Oahu
- Monitoring and emergency service run 24/7; the help desk is staffed seven days a week from 4 a.m. to 11 p.m. Eastern time
- Month-to-month agreements and 98% client retention
What an IT company handles for a Hawaii organization
Searching for an IT company in Hawaii usually means one of two situations: a Honolulu office that has outgrown part-time help, or a business with people on several islands and no single owner for its technology. NetSys can take either. One agreement covers engineers on the help desk, patching and monitoring through NinjaOne, ThreatDown on every endpoint, Microsoft 365, Intune and Entra ID administration, Barracuda email filtering, Keeper passwords, KnowBe4 training and Datto or Veeam backups proven by restore tests. We manage firewalls, switches and Wi-Fi at each site from cloud dashboards, keep the documentation in IT Glue and take every call to carriers and software vendors. For a multi-island business, that means one set of security policies and one help desk number whether an employee sits in Kakaako, at a resort office in Wailea or in a clinic in Hilo. Companies with their own IT person can split the work with us as co-managed IT.
How remote support works across the islands
Every Hawaii engagement is remote, on Oahu and on the neighbor islands alike. Engineers reach computers through the NinjaOne agent and network equipment through Meraki or Fortinet cloud consoles, and staff reach us by phone, email or Teams. Hardware travels as freight: a replacement laptop is shipped by the supplier already enrolled in Windows Autopilot, and a firewall for a branch in Kahului or Lihue arrives configured so an office manager or local cabling contractor can install it while we watch it connect. Inter-island shipping adds a step, so each site should keep an enrolled spare. Time zones shape the day as well. Hawaii does not observe daylight saving time, so the gap to New York is six hours from March to early November and five hours in winter. Our help desk, staffed 4 a.m. to 11 p.m. Eastern, closes at 5 p.m. Hawaii time in summer and 6 p.m. in winter and reopens late that night; urgent problems in between reach your dedicated engineer.
Industries across the islands and the systems they run
Tourism leads the state's economy: preliminary DBEDT figures show 9.64 million visitors in 2025, spending $21.75 billion. Resorts from Waikiki to Wailea, Kaanapali and the Kona and Kohala coasts run property-management systems, point-of-sale terminals and guest Wi-Fi that must stay separate. Defense is the second largest industry, according to the state's defense economy office, with Pearl Harbor and the Indo-Pacific Command on Oahu, the Maui High Performance Computing Center in Kihei and the Navy's Pacific Missile Range Facility at Barking Sands on Kauai, each with contractors handling controlled information. Health care employs on a similar scale: The Queen's Health Systems and Hawaii Pacific Health are the state's two largest private employers, and Maui Health and Adventist Health Castle also rank in the top 25. Banks, insurers, construction firms, property managers and nonprofits fill out the picture. We build each environment around its applications and the rules that come with them.
Inter-island cables and why every site needs a backup path
Data moves between the islands over a short list of undersea cables. The University of Hawaii says three systems connect the islands and two of them have run past their 25-year design life. The risk is not theoretical: on October 27, 2019, a fault in the cable between Oahu and Kauai cut most of Kauai off from internet, cable TV and phone service for about a day, and service failed again days later. The Hawaiian Islands Fiber Link, a roughly $140 million open-access system with new landings on Kauai, Oahu, Molokai, Lanai, Maui and Hawaii Island, was first targeted for 2026 and is now expected in 2027. Hawaiian Telcom, meanwhile, aims to bring fiber to every home and business in the state by the end of 2026. Until the new cable is in service, we treat each neighbor-island office as one that may lose its link: a second carrier or a Starlink Business terminal, offline file sync and a local backup copy.
Fire, floods and separate grids: continuity across Hawaii
The August 2023 wildfires showed how fast a business can lose everything at once. FEMA declared disaster DR-4724 on August 10, and the FCC's status reports show that all 21 cell sites serving West Maui from Kapalua to Olowalu were out of service in the first days, while cable and wireline providers still counted 14,466 subscribers without service on August 20. In March 2026 Kona low storms led to declaration DR-4909 for Hawaii, Honolulu and Maui counties. Power is island by island: the Public Utilities Commission notes that each main island's grid connects to no other, and on the morning of January 30, 2024 Hawaii Island saw rolling outages for about 25,500 customers after several large generators went offline. Our continuity plans for island businesses assume the building may be unreachable: Microsoft 365 and line-of-business data backed up outside the state, laptops staff can take home, and contact lists that do not rely on the office phone system.
State law and industry rules that shape IT in Hawaii
Two state statutes apply to almost every business. Under HRS 487N-2, an organization that owns or licenses personal information about Hawaii residents must notify affected people without unreasonable delay after discovering a breach; when more than 1,000 people receive notice at one time, the business must also tell the State Office of Consumer Protection and the national consumer reporting agencies in writing. HRS 487R-2 requires reasonable measures against unauthorized access when records are thrown out, including erasing electronic media. Hawaii adopted the NAIC insurance data security model in 2021 as Act 112, now HRS article 431:3B, which requires a written information security program and gives covered licensees three business days to report qualifying events to the commissioner. Health care providers work under the HIPAA Security Rule, merchants under PCI DSS, and Department of War suppliers under DFARS 252.204-7012 and NIST SP 800-171, with CMMC Phase 2 suspended since July 13, 2026. This is general information, not legal advice.

Hawaii FAQs
Who provides IT services across Hawaii?
Hawaii has local IT firms on Oahu and the larger neighbor islands, plus national providers that work remotely; NetSys is one of the remote options. We are a managed IT and cybersecurity company founded in 1998 with one office, in Brooklyn, and we support Hawaii organizations over the network without sending anyone on site. A business that needs a technician physically present within the hour should hire locally. One that wants an engineering team, written response commitments and the same security stack on every island can work with us on month-to-month terms.
How does IT support work for Hawaii organizations?
Through phone, email, Teams and remote-control tools, all from Brooklyn. Engineers fix devices through the NinjaOne agent, manage Microsoft 365 and Intune in Microsoft's consoles and run firewalls from the cloud. Computers ship to any island ready for first sign-in, and local staff or contractors connect network equipment while we verify it. Staffed hours are 4 a.m. to 11 p.m. Eastern time; ransomware, systems down, no internet or failed email go to your dedicated engineer, and emergency service runs 24/7. We do not send engineers on site in Hawaii.
Can one agreement cover offices on several islands?
Yes. A business with staff in Honolulu, Kahului and Kailua-Kona gets one Microsoft 365 tenant, one set of Intune and Conditional Access policies, one help desk number and one monthly invoice. Each site gets its own firewall, managed from the same cloud dashboard and linked back to the main office over site-to-site VPN or SD-WAN if it needs shared resources. Pricing is per user, with site-specific items such as a backup circuit quoted per location. Documentation in IT Glue lists each site's carrier, circuit ID and local contacts.
How much do IT services cost for a Hawaii business?
Managed IT is a per-user monthly fee set after an assessment; we do not publish prices. What moves the figure in Hawaii is mostly structural: how many islands and sites you run, whether servers still sit in a closet, backup internet and power at each location, compliance evidence for HIPAA, PCI DSS, insurance regulators or a defense contract, and coverage beyond monitoring outside staffed hours. Hardware, freight and licensing are quoted separately, and projects such as a tenant migration are priced after scoping. Agreements run month to month.
What happens when an inter-island cable fails?
Offices on the affected island may lose internet, phone service or both, and we lose our path in as well, because remote support needs a working connection. That is why we design neighbor-island sites with a second path from a different provider, satellite service included, chosen after checking how each provider's traffic leaves the island, and keep a local backup copy so restores do not depend on the link. Staff keep working from files synced offline and cached sign-ins. When service returns, monitoring catches up and we review what failed.
How does remote onboarding work for businesses in Hawaii?
The first conversation is a video call, followed by read-only access to Microsoft 365, the firewall and backups. Staff on every island install the NinjaOne agent from an emailed link, and we document devices, accounts, licenses, circuits and vendors site by site. A written plan with dates and costs follows in about two weeks. Cutover runs in stages, often one island at a time, with changes timed for our early morning, which is the night before in Hawaii. Hardware that needs replacing is ordered early because freight to the neighbor islands takes longer.
What did the Maui wildfires teach businesses about IT continuity?
Mainly that a plan has to work when the building, the phones and the local network are gone at the same time. In West Maui, cell service and wired connections failed together, and many businesses lost their premises outright. A business is far better placed in that situation when its email and files live in Microsoft 365, its backups sit off the island, its staff carry laptops rather than relying on desktops, and it can reach employees without office lines. We build those pieces into every Hawaii agreement and run restores on a schedule, because an untested backup is only a hope.
Which Hawaii industries does NetSys build IT for?
Our industry pages cover hospitality, health care, government contractors, banks and credit unions, real estate, construction and nonprofits, the sectors that dominate Hawaii's economy. For hotels and resorts we separate guest networks from payment systems. For clinics we document HIPAA safeguards. For defense suppliers on Oahu, Maui and Kauai we build an enclave for controlled unclassified information and keep the SPRS score current. The industry pages describe that work in detail; none of the employers named on this page is a NetSys client.
