MJN Technology Services is Long Island’s security-first MSP, GTIA Cybersecurity Trustmark Certified, 5.0-star rated, and leading businesses into the era of managed AI and Zero-Trust defense.
Steven Giacoppo is the President of MJN Technology Services, an IT, cybersecurity, and AI implementation firm based in Wantagh, New York. In 2024 he co-authored Your Business Will Get Hacked, a best-selling book that gives business owners a clear-eyed playbook for surviving the modern threat landscape.
With more than 20 years in the field, Steven built MJN on a simple conviction: businesses deserve a trusted adviser, not just another computer company. As cyber threats grew exponentially, he pivoted MJN to a security-first model — deploying Zero-Trust architecture, SASE, and 24/7 MXDR/SIEM threat hunting on the front lines of cyber defense. Today he is leading clients into the next frontier: managed AI implementation that drives growth while keeping data locked down.
MJN is powered entirely by experienced, US-based in-house engineers. Nothing critical is outsourced overseas when you call, you reach a dedicated team that knows your business and the complexities of modern security.
Away from the keyboard, Steven is an avid saltwater fisherman who spends his time with his wife and three young boys fishing, clamming, and crabbing along the shores of Long Island.
MJN Technology was founded on the belief that businesses don’t need another all-around computer company — they need a specialist who understands their industry and engineers their technology around it. That conviction shaped two decades of disciplined evolution: bulletproof continuity through daily screenshot-verified backups and automated Microsoft 365/SaaS protection, then a full security-first transformation built on 24/7 SIEM/MXDR threat hunting, automated endpoint remediation, and proactive risk assessments.
Today that same discipline powers our newest chapter: managed LLM integration, intelligent workflow automation, and predictive IT analytics that eliminate downtime before it happens.
To be the partner businesses trust to navigate both AI and cyber defense — proving every day that intelligent automation and absolute security belong together.
We do the right thing by our clients, always — full stop. Our flawless 5.0 Google rating wasn’t bought; it was earned one honest recommendation at a time, over 20 years.
Excellence is a discipline, not a milestone. From our GTIA Cybersecurity Trustmark certification to continuous training in emerging AI and security tooling, we never stop sharpening.
Trust is built on predictability. Daily screenshot-verified backups, 24/7 threat monitoring, and a US-based team that answers when you call — consistency you can set your watch to.
We move first so our clients never fall behind — pioneering managed AI implementation, Zero-Trust architecture, and intelligent automation that makes businesses safer, faster, and more efficient.
