Technology support that actually supports you
We know what it's like when technology fails at the worst possible moment. That's why we build systems with redundancy, document everything, and stay reachable when you need us most.
- Real people answer the phoneNo ticket queues, no offshore support. When you call SD3 Tech, you talk to someone who knows your system.
- We document everythingClear system documentation means faster support, easier audits, and no knowledge locked in one person's head.
- Security-first from day oneEvery solution we design includes security by default — not bolted on at the end as an afterthought.
- Local to Northern UtahBased in Layton — we can be on-site quickly when remote support isn't enough.

Real Outcomes for Real Clients
A few examples of challenges we've solved — across industries, on time, without the drama.
Unplanned Downtime Cut by 60% with Predictive Monitoring
A mid-size manufacturer was averaging 14+ unplanned shutdowns per quarter due to sensor drift and missed alarm thresholds on aging PLC equipment. Maintenance was reactive and expensive.
"We went from chasing alarms to anticipating them. The ROI was visible within the first month."
Legacy Server Fleet Hardened and Auditable in Under 30 Days
A multi-site infrastructure operator had 40+ aging Linux servers with inconsistent configurations, no centralized logging, and no documented patch history — flagged as high risk in an internal audit.
"We went from audit panic to audit confidence. Every system is documented, patched, and monitored."
Real-Time Operations Dashboard Replaced $180K SCADA Upgrade
A regional utility was quoted $180K to upgrade their aging SCADA platform to gain better operational visibility. Their existing PLCs and historians were fully functional — just siloed.
"Same visibility the vendor promised, at a fraction of the cost. It's been running flawlessly for two years."
