SVC / 01
Managed IT Services
Day-to-day operational ownership of the environment. Patching, monitoring, ticket triage, identity, and the runbook that ties the rest of the stack together.
[ SVC / 01 ]Service Catalog
Enterprise IT Infrastructure Services
Six operational disciplines. One runbook.
Every Licht Data engagement is staffed by senior engineers who own the stack end to end — from the cloud and server tier through the network edge, the voice fabric, and the security posture that holds it all together. The catalog below is what we run, day in and day out, for multi-site enterprise teams.

[ SVC / 02 ]The Catalog
Six capabilities, one senior engineering practice.
Each capability is staffed by senior engineers who carry the context across the stack. No tier-one handoffs, no tribal knowledge trapped in a single head.
SVC / 02
Cybersecurity
A defended environment, not a checklist. Endpoint detection, identity hardening, privileged-access controls, and compliance evidence maintained as a living operational artifact.
SVC / 03
Network Infrastructure
Multi-site connectivity engineered for predictable performance — branch to data center, branch to cloud, and SD-WAN topologies that hold up under load.
SVC / 04
Cloud Infrastructure
Hybrid cloud and on-premises server estates operated as one continuous tier — tenancy design, hypervisor operations, and recovery posture rehearsed against documented objectives.
SVC / 05
Business Communications
Voice, SIP trunking, and unified communications — operated as production infrastructure, with number porting, E911, and regulatory posture handled alongside the rest of the stack.
SVC / 06
Business Internet
Business-grade connectivity — dedicated internet access, fiber and broadband, carrier selection and coordination, primary and secondary circuit design, and lifecycle management across multi-site footprints.
[ SVC / 02.B ]Integrated Infrastructure Model
Capabilities operate as one interconnected environment — not isolated products.
The six capabilities above are not a menu of unrelated services. Below is how the layers are sequenced in operating practice — an explanatory model, not a mandatory technical dependency.
01
Business Internet / Carrier Connectivity
Where the environment meets the outside world. Circuit selection, primary/secondary design, and carrier coordination that the rest of the stack depends on.
02
Network Infrastructure
The fabric that carries traffic between sites, clouds, and users. SD-WAN, routing, and QoS policy shaped around the workloads that actually run.
03
Cybersecurity
The posture that holds everything accountable. Detection, identity, and privileged-access controls aligned with the existing security operations.
04
Cloud + Server Infrastructure
Where workloads live. Tenancy design, hypervisor operations, and recovery procedures tested against documented time objectives.
05
Business Applications + Communications
Microsoft 365, line-of-business applications, voice, and unified communications — operated as production infrastructure, not productivity shelfware.
06
Managed Operations
The senior engineering practice that ties the layers together. Monitoring, patching, escalation, and the runbook that keeps the environment from drifting.
The stack above is descriptive of how Licht Data sequences operations across an environment. Each engagement is shaped to the customer's context — not every layer exists in every footprint, and the order is a working model rather than a fixed contract.
[ SVC / 03 ]Engagement Model
How an engagement actually starts.
No bait-and-switch staffing. No discovery deck that never becomes an implementation. The same engineers who scope the work run the work.
01
PHASE / 01Step one
Architecture Review
A senior engineer walks the full stack with you — current state, gaps, and the operational risks that matter most. Findings are written as a working document, not a slide deck.
02
PHASE / 02Before any handoff
Runbook Construction
The runbook is built before day-to-day operations transfer. Monitoring thresholds, escalation paths, change windows, and recovery procedures are documented and rehearsed against the live environment.
03
PHASE / 03When the runbook is ready
Operational Handoff
Day-to-day operations transfer to the on-account engineering team. The same engineers who built the runbook remain on the account — no context loss, no tier-one handoff.
04
PHASE / 04Ongoing
Continuous Posture Review
The runbook is walked against the live environment on a recurring basis. Drift is documented, gaps are closed, and the next cycle is planned against evidence.
[ SVC / 04 ]Fit & Scope
Where Licht Data is the right fit — and where we are not.
Fit is determined by infrastructure complexity, operational dependency, regulatory requirements, and how business-critical the IT perimeter has become — not by site count alone.

[ SVC / 05 ]Next Step
Begin with an Architecture Review.
Written findings, not a slide deck.
The Architecture Review begins with a senior engineer walking the full stack alongside your team. You receive a written assessment of the current operational posture, the gaps that matter, and a sequenced path forward — whether or not you ever become a Licht Data customer.
