Help Desk Support
Remote and phone-based support for everyday IT issues — software problems, connectivity issues, device configuration, and general user support.
On-Site Service Calls
When remote support isn't enough, our technicians come to you. Fast on-site response for hardware failures, network issues, and hands-on troubleshooting.
Troubleshooting & Diagnostics
Systematic diagnosis of hardware, software, and connectivity problems — identifying the root cause and resolving it correctly the first time.
System Updates & Patching
Firmware updates, security patches, and software updates across your devices to keep systems current, stable, and protected against known vulnerabilities.
Basic Maintenance
Scheduled maintenance visits to inspect hardware, clean up software, verify backups, and address any issues before they cause downtime.
Device Setup & Configuration
Setup and configuration of computers, printers, mobile devices, and peripherals — properly configured and ready to use from day one.

Why Choose ET Security
Local IT support that knows your systems and responds fast.
Fast Response Times
IT issues cost you time. We prioritize fast response — remote support often within the hour, on-site same or next day depending on urgency.
Local Long Island Technicians
Our technicians are based in Hauppauge and serve Nassau and Suffolk Counties. No outsourced support — real people who know your systems.
Thorough Diagnostics
We don't guess. We systematically diagnose the root cause of every issue before recommending a fix, so the same problem doesn't come back.
No Long-Term Contracts Required
We offer flexible support options — pay-as-you-go service calls or scheduled maintenance agreements — with no pressure to commit to long-term contracts.
Attention to Detail
We take our time to do the job right. Every service call is documented, every fix is tested, and we don't close a ticket until the issue is fully resolved.
Transparent Pricing
We provide clear, upfront pricing before any work begins. No surprise charges, no hidden fees — just honest, professional service.
Our Process
A straightforward approach to getting your IT issues diagnosed and resolved quickly.
Contact & Assessment
Reach us by phone or email to describe your issue. We assess the problem, determine whether remote or on-site support is needed, and schedule a time that works for you.
Diagnosis & Repair
We systematically diagnose the root cause — remotely when possible, on-site when required — and carry out the repair, update, or maintenance work needed to resolve it.
Testing & Follow-Up
We test all affected systems to confirm everything is working correctly, document the work completed, and advise on any steps to prevent the issue from recurring.
