IT Infrastructure for 50–300 Person Companies
At this stage companies usually add servers, branches and business systems faster than their original IT design evolves. The goal is a manageable baseline for segmentation, identity, backup and operations—not simply more equipment.
The company has grown but still uses an early-stage network and file-share design / Servers, NAS, VMs and ERP/MES expanded without architectural review

Typical situations
The company has grown but still uses an early-stage network and file-share design
This usually indicates that the environment lacks a consistent operating baseline. We first confirm ownership, dependencies and business impact.
Servers, NAS, VMs and ERP/MES expanded without architectural review
These issues often span several systems. Treating only the visible symptom can cause repeat incidents, so the dependency path is reviewed first.
Accounts, permissions, VPN and endpoint policy have become inconsistent
When support depends on ad-hoc fixes, recovery, handover and future expansion become harder to manage.
More equipment exists but topology, backup and change records are missing
For production systems, changes are planned around an approved window, validation steps and rollback conditions.
Scope of work
Network segmentation, core/access, Wi-Fi and server-zone design
Included in the operating baseline with clear ownership, checks and escalation boundaries.
AD/DNS/GPO, identity lifecycle and endpoint policy
Work is adapted to the existing architecture and business dependencies rather than forcing a rebuild for its own sake.
Server, virtualization, storage, NAS and application hosting plan
For business-critical systems, backup state, access paths and recovery options are verified before change work begins.
File-share permissions, offboarding and access audit
Material changes are documented with implementation notes, validation results and rollback information where required.
Veeam/backup storage, recovery tests and RPO/RTO
Cross-system work starts by confirming prerequisites, owners and the expected blast radius.
VPN/branch connectivity, monitoring, logging, documentation and operations baseline
The work can be delivered as a defined project or an ongoing support scope, depending on the requirement.

Engagement approach
Discovery
Confirm business systems, devices, impact, ownership and the current operating context.
Boundaries & risk
Map dependencies, access paths, backup state and services that cannot be interrupted.
Plan & window
Define scope, maintenance window, risk, validation steps and rollback conditions.
Implementation & validation
Execute the agreed work and validate service, access, performance or recovery outcomes.
Documentation & ongoing operations
Update topology, configuration, identity, backup or operations records and document follow-up items.
Frequently asked questions
Q: Is an on-site visit required first?
A: Not always. Initial discovery can often start from topology, screenshots and system information; on-site work is used when hardware, complex networking or production change requires it.
Q: Can you handle only one scoped area?
A: Yes. Server, network, permissions, backup and migration work can be scoped independently when boundaries are clear.
Q: Will this affect production systems?
A: Production changes are planned around a maintenance window, backup, validation and rollback. We do not make blind changes to an unknown environment.
Q: Do you provide documentation?
A: Yes. Depending on scope, deliverables can include inventories, topology, configuration records, implementation/acceptance records and maintenance guidance.
