Infrastructure — New York / Tri-State
IT infrastructure services for New York businesses
Networks, firewalls, Wi-Fi, and servers are the layer everything else stands on. Stedholm designs them from requirements, documents them as built, and monitors them continuously — instead of managing an accumulation.
Most networks are accumulated. Ours are designed.
The typical small-business network is archaeology: a switch added during an office move, firewall rules nobody dares delete, an access point screwed to the wall where the dead spot was, a server named after someone who left in 2019. Each decision was reasonable at the time. The sum is fragile, undocumented, and understood by exactly one person — if you are lucky.
We work in the opposite order. Requirements first, then a design, then documentation, then the build, then monitoring — and when we inherit an existing environment, we document it before we change anything, because you cannot responsibly modify what you cannot describe.
Infrastructure is one of the four things we run as a single discipline. It carries the managed IT your users feel and enforces the segmentation your security posture depends on — the same team runs both ends.
01 — Infrastructure services
Three layers, one discipline
Each service stands alone as a project or an ongoing engagement; together they cover the physical and virtual ground your business runs on.
Network
Network design & management
Segmentation, addressing, and resilience designed on paper before they exist in hardware — then monitored, backed up, and change-controlled. Documentation-first, always.
Edge
Wi-Fi, SD-WAN & firewalls
Firewalls with reviewed rulebases, remote access tied to identity, Wi-Fi engineered from surveys rather than guesswork, and SD-WAN that keeps multi-site firms on the air.
Compute
Virtualization & servers
Hyper-V and VMware management, hardware lifecycle, patching, and a straight answer on what belongs on-premises, in a colo, or in the cloud.
Documentation is a deliverable, not a byproduct
An undocumented network is a liability with blinking lights. Every change is risky because nobody knows what depends on what; every outage is longer because diagnosis starts from zero; and every departure of a knowledgeable person is a small disaster. Documentation is how infrastructure stops being tribal knowledge.
So we treat the documents as deliverables with the same status as the hardware: produced during the work, kept current by change control, and owned by you. If you leave Stedholm, the next provider inherits a described environment — that is a promise we are structurally comfortable making.
Every engagement produces
A current network diagram
An IP addressing and VLAN plan
Configuration backups with change history
A hardware inventory with lifecycle dates
A monitoring and escalation runbook
How we operate infrastructure
Continuous monitoring
Devices, circuits, and capacity are watched around the clock by our tooling, with engineer escalation when something needs a human.
Change control
Modifications are planned, communicated, and reversible — the configuration backup exists before the change does.
Firmware and lifecycle management
Updates on a schedule rather than after an incident, and replace-by dates budgeted years ahead, not discovered at failure.
Carrier and vendor coordination
We deal with ISPs, carriers, and hardware vendors on your behalf — one throat to choke is ours to provide, not yours to hunt for.
Capacity reviews
Utilization is reviewed on a cadence so growth is planned instead of announced by a saturated uplink.
Security alignment
Segmentation, firewall policy, and remote access are designed with our security practice — the network is where a security architecture becomes real.
Common questions
Can you take over a network you didn't build?
Yes — that is the normal case. We document what exists, stabilize it with config backups, monitoring, and credential custody, and only then start improving it on a prioritized plan. Nothing gets ripped out to satisfy a vendor preference.
Do you handle one-off projects, or only ongoing management?
Both. Office moves, network redesigns, firewall replacements, and server refreshes work as scoped projects with their own deliverables. Ongoing management is a separate decision, and the documentation is yours either way.
We have offices in New Jersey and Connecticut too. Does that work?
Yes — multi-site is where design pays for itself, and SD-WAN in particular. We work across the Tri-State area, remote-first with onsite when it is genuinely needed; see locations.
How does infrastructure relate to your security services?
The network enforces what security policy declares: segmentation limits how far an intruder can move, firewall rules are policy in packet form, and remote access is an identity decision. Device hygiene lives here; detection and response live in cybersecurity — same team, deliberately.
Put a design under your infrastructure.
An engineer will look at what you have accumulated and tell you what is sound, what is fragile, and what to fix first.
