RTP | Recommended Technology Platform

The Stack We Build On

Every product below has earned its place in our environment through years of real-world deployments. This is what we recommend, what we deploy, and what we stand behind – from the domain controller to the desktop to the UPS in the closet.

nhdIT Recommended Technology Platform
What Is the RTP?

A Standard, Not a Sales Pitch

The Recommended Technology Platform is our published reference architecture – the specific vendors and products we have standardized on across every client we support. It exists so that decisions get made once, correctly, instead of over and over under pressure.

When your environment matches the RTP, everything downstream gets easier: our technicians already know the hardware, our documentation already covers the configuration, spare parts are already on the shelf, and security baselines are already written. When something breaks at 4:45 on a Friday, familiarity is worth more than features.

Proven in Production

Nothing lands on this list because of a datasheet. Every product here runs in environments we are personally responsible for.

Serviceable & Supported

Real vendor support contracts, obtainable parts, and long support lifecycles. No orphaned gear, no dead-end platforms.

Built to Scale

The same architecture works at five users and at two hundred. You grow into the platform instead of replacing it.

Predictable Cost

Known refresh cycles, known licensing, known lifespans. Standardization is how IT budgets stop producing surprises.

The Stack in Detail

Why Each Layer Is What It Is

Every choice below comes with a reason. If you disagree with one, we would genuinely like to hear it – that is how the list gets better.

LAYER 01

Microsoft 365

Productivity, Email & Identity

Microsoft 365 is the anchor of the platform. It delivers business email, the Office applications your staff already know, cloud file storage, collaboration, and – most importantly – a modern identity provider with conditional access and multi-factor authentication built in. Business Premium is our default recommendation because it bundles the security and device management capabilities that smaller organizations otherwise go without.

  • Exchange Online business email
  • Word, Excel, Outlook, PowerPoint
  • Teams for chat, meetings and calling
  • SharePoint & OneDrive file storage
  • Entra ID with MFA and conditional access
  • Intune device management and policy

Why it wins: one identity, one license, one support path covering email, documents, collaboration, and endpoint policy.


LAYER 02

Windows Server

Domain Controllers & Core Services

On-premises identity still matters. Active Directory Domain Services remains the cleanest way to centrally manage Windows machines, enforce Group Policy, control file and print access, and keep authentication working when the internet does not. We deploy current, in-support Windows Server releases – typically with a pair of virtualized domain controllers for redundancy – and hybrid-join them to Entra ID so cloud and on-premises identity stay in sync.

  • Active Directory Domain Services
  • DNS and DHCP services
  • Group Policy standardization
  • File and print services
  • Entra Connect hybrid identity sync
  • Certificate services where required

Why it wins: centralized control over Windows endpoints that no cloud-only approach fully replaces yet.


LAYER 03

Proxmox VE

Virtualization & Backup

Proxmox Virtual Environment is our hypervisor of choice. It is enterprise-grade KVM virtualization built on Debian, with clustering, high availability, live migration, ZFS storage, and snapshotting – without per-socket licensing that scales faster than your business does. Paired with Proxmox Backup Server, it gives you deduplicated, incremental, verifiable backups of every virtual machine, with restores measured in minutes.

  • KVM virtual machines and LXC containers
  • Clustering and high availability
  • Live migration for zero-downtime maintenance
  • ZFS with snapshots and replication
  • Proxmox Backup Server integration
  • Enterprise support subscriptions available

Why it wins: enterprise virtualization features at a cost structure that makes sense for a small business, with no vendor holding your workloads hostage.


LAYER 04

Dell PowerEdge

Server & Storage Hardware

Dell server hardware is the foundation everything else sits on. iDRAC out-of-band management means we can diagnose, reconfigure, and rebuild a server without driving to your office. ProSupport contracts put replacement parts on site the next business day – and in many cases, a technician with them. Redundant power supplies, hot-swap drives, and hardware RAID are standard, not upgrades.

  • PowerEdge tower and rack servers
  • iDRAC Enterprise remote management
  • Redundant power and hot-swap drives
  • Direct-attached and SAN storage
  • ProSupport next-business-day coverage
  • Certified refurbished options available

Why it wins: serviceable hardware with real support behind it, and remote management that turns most emergencies into remote fixes.


LAYER 05

TrueNAS

Shared Storage & File Services

Where a client needs serious shared storage – a file server, a datastore for the virtualization cluster, or a backup target – we deploy TrueNAS. It is built on OpenZFS, which is the reason it is on this list: end-to-end checksumming catches silent data corruption that traditional RAID never notices, and instant, space-efficient snapshots turn a deleted folder or an encrypted share into a rollback rather than a restore.

TrueNAS presents storage over SMB, NFS, and iSCSI, so it can serve Windows file shares and Proxmox datastores from the same pool. Scheduled replication pushes snapshots to a second unit or an off-site target, which pairs naturally with our off-site backup service.

  • OpenZFS with end-to-end checksumming
  • Instant snapshots for fast recovery
  • Replication to a second or off-site unit
  • SMB, NFS and iSCSI from a single pool
  • Active Directory integration for share permissions
  • Scrubs, SMART monitoring and alerting

Why it wins: ZFS data integrity and snapshot-based recovery on hardware you own, with no per-terabyte licensing. Read-only snapshots are also one of the most effective ransomware defenses available – encrypted files simply get rolled back.


LAYER 06

Dell & HP

Desktops & Laptops

We deploy business-class machines only – Dell OptiPlex and Latitude, HP Elite and Pro. Consumer models cost less up front and more over their lifetime: shorter warranties, no on-site service, no standardized imaging, no firmware management, and no guarantee the same model exists in six months. Business lines give us stable configurations we can image, document, and support consistently across your fleet.

  • Dell OptiPlex desktops and micro form factor
  • Dell Latitude business laptops
  • HP EliteDesk / ProDesk desktops
  • HP EliteBook / ProBook laptops
  • TPM 2.0 and BitLocker encryption standard
  • On-site warranty and business support lines

Why it wins: longer warranties, on-site service, stable model lines, and manageable firmware – the things that actually determine total cost of ownership.


LAYER 07

Windows 11 Pro

Desktop Operating System

Windows 11 Pro or newer, on every workstation. Pro is the minimum edition – Home cannot join a domain, cannot be managed by Group Policy or Intune, and cannot use BitLocker properly, which rules it out of any managed environment. We keep endpoints on supported feature releases and patch them on a defined cadence rather than whenever a user happens to reboot.

  • Windows 11 Pro minimum on all endpoints
  • BitLocker full-disk encryption
  • Secure Boot and TPM 2.0 enforced
  • Managed patching on a defined schedule
  • Standardized imaging and provisioning
  • Supported feature releases only

Why it wins: it is the only desktop OS that fully supports the management, encryption, and policy controls the rest of this platform depends on.


LAYER 08

Ubuntu & Debian

Linux Server Platforms

For Linux workloads – web applications, databases, internal tooling, container hosts, appliances – we standardize on Ubuntu Server LTS and Debian Stable. Both offer multi-year support windows, predictable release cadences, enormous package ecosystems, and security update streams you can actually plan around. Ubuntu LTS gives five years of standard support out of the box; Debian Stable prioritizes conservatism, which is exactly what you want under a database.

  • Ubuntu Server LTS long-term support releases
  • Debian Stable for conservative workloads
  • Unattended security updates
  • Docker and container hosting
  • Hardened SSH and firewall baselines
  • Centralized monitoring and log shipping

Why it wins: long support lifecycles, no licensing overhead, and the same two distributions our team knows inside out.


LAYER 09

Cisco & Ubiquiti

Managed Switching

Managed switches, always. Unmanaged switches are invisible – no VLANs, no port security, no PoE control, no visibility when something floods the network. Cisco Catalyst is our recommendation where deep feature sets, strict compliance requirements, or existing Cisco investment are in play. Ubiquiti UniFi is our recommendation where a clean, unified management plane and excellent price-to-capability matter more.

  • VLAN segmentation for voice, data and guest
  • PoE / PoE+ for phones, cameras and APs
  • Link aggregation and uplink redundancy
  • Port-level monitoring and alerting
  • 802.1X where the environment calls for it
  • Documented port maps and configurations

Why it wins: segmentation and visibility at the network edge – the cheapest security control you will ever buy.


LAYER 10

UniFi Wireless

Access Points & Coverage

Ubiquiti UniFi access points give you genuine enterprise wireless – seamless roaming, multiple SSIDs mapped to separate VLANs, band steering, per-client visibility, and centralized firmware management – without a controller licensing model. We design coverage around your floor plan and construction, not around guesswork, and we put guest traffic on its own isolated network as a matter of course.

  • Wi-Fi 6 / 6E access points
  • Seamless roaming across the facility
  • Isolated guest network by default
  • Per-SSID VLAN mapping
  • Centralized controller management
  • Coverage planning and post-install validation

Why it wins: enterprise wireless behavior, centrally managed, with no recurring per-AP licensing.


LAYER 11

UniFi / pfSense / OPNsense

Routing & Perimeter Firewall

The edge is where your network meets everything else, and the ISP-supplied box is not a firewall. For environments already standardized on UniFi, a UniFi gateway keeps routing, switching, and wireless under one management plane. Where you need deeper policy control, granular VPN configuration, or full transparency into the ruleset, we deploy pfSense or OPNsense on purpose-built hardware.

  • Stateful firewalling with documented rules
  • Site-to-site and remote access VPN
  • Inter-VLAN policy enforcement
  • Intrusion detection and prevention
  • Multi-WAN failover where uptime demands it
  • Configuration backups held off-site

Why it wins: a real firewall with a ruleset we control, document, and can restore in minutes.


LAYER 12

SentinelOne

Endpoint Protection & EDR

SentinelOne is our standard for endpoint protection on every workstation and server. It is not signature-based antivirus – it watches behavior, and when it identifies an attack it contains the machine and remediates automatically, including rolling back ransomware encryption. That distinction matters most at 2:00 AM, when the response has to happen without a human in the loop.

  • Behavioral AI threat detection
  • Automated containment and remediation
  • Ransomware rollback
  • Windows, Linux and macOS coverage
  • Threat hunting and forensic timelines
  • Monitored by our team, not left to alert you

Why it wins: autonomous response. It stops the attack whether or not anyone is watching the console. See our full security software stack for the layers that sit alongside it.


LAYER 13

DNSFilter

DNS Security & Content Filtering

Almost every attack has to resolve a domain name before it can do anything. DNSFilter sits at that step and refuses to answer for known-malicious and newly-registered domains, which stops a great deal of malware and phishing before a single packet reaches the target. It is the broadest protection in the stack: it covers every device on the network – printers, cameras, phones, guest laptops, anything you cannot install an agent on.

The same platform handles content filtering by category, so acceptable-use and compliance requirements are enforced without a separate product. Roaming agents extend the same policy to laptops that have left the office.

  • Malicious and phishing domain blocking
  • Real-time domain categorization
  • Category-based content filtering
  • Roaming client for off-network laptops
  • Agentless coverage for IoT and guest devices
  • Query logging and reporting

Why it wins: the cheapest and widest-reaching control on this list. It protects things you cannot put software on, and it blocks threats before the connection is ever made.


LAYER 14

Proofpoint

Email Security & Threat Protection

Email remains the way most breaches start, and the filtering bundled with a mail platform is not built to stop a targeted attack. Proofpoint sits in front of Microsoft 365 and inspects mail before it reaches the mailbox – sandboxing attachments, rewriting links so they are checked again at click time, and catching the business email compromise attempts that carry no payload at all and therefore sail past conventional scanning.

That last category is the one that costs businesses real money: a convincing message from “the owner” asking accounting to change wire instructions. There is no malware to detect, only intent, and that is precisely what this layer is tuned for.

  • Advanced phishing protection
  • Business email compromise defense
  • Attachment sandboxing
  • URL rewriting and click-time protection
  • Email encryption for sensitive messages
  • Security awareness training

Why it wins: it filters your single largest attack surface before delivery, and it catches the social-engineering attempts that contain nothing for an antivirus engine to find.


LAYER 15

APC & CyberPower

Uninterruptible Power

Every server, switch, firewall, and access point belongs on a UPS – ideally a line-interactive or online model with pure sine wave output, because modern power supplies do not tolerate simulated waveforms well. APC Smart-UPS is our default; CyberPower PR and OR series are an excellent value alternative. We size units to real load, configure automatic graceful shutdown, and track battery age so replacement happens on schedule instead of during an outage.

  • APC Smart-UPS line-interactive and online
  • CyberPower PR / OR series
  • Pure sine wave output
  • Network management cards for monitoring
  • Automated graceful shutdown integration
  • Battery lifecycle tracking and replacement

Why it wins: clean power and controlled shutdowns prevent the filesystem corruption and hardware failures that turn a brief outage into a multi-day recovery.

The Case for a Standard

Why Standardization Beats Best-of-Breed

An environment assembled from whatever was on sale each year is an environment nobody fully understands – including the people who built it. A standard platform trades a little theoretical optimization for something far more valuable: predictability.

Faster Resolution

Our technicians have seen your exact configuration before. Diagnosis starts from knowledge, not discovery.

Interchangeable Spares

Common models mean common parts. A failed workstation gets swapped from stock instead of ordered and waited on.

Consistent Security Baselines

One hardening standard applied everywhere. No forgotten device running a configuration nobody documented.

Planned Lifecycles

Known refresh windows and known end-of-support dates mean capital planning happens in advance, not in crisis.

Standardized IT infrastructure
Adoption

You Do Not Replace Everything on Day One

Nobody rips out a working environment to match a document. We align you to the platform over time, at natural replacement points.

1
Inventory

We document what you actually have – hardware, licensing, firmware, warranty status, and end-of-support dates.

2
Gap Analysis

We compare it against the RTP and rank the differences by risk, age, and business impact – not by what we would like to sell.

3
Roadmap

A multi-year plan tied to your budget cycle. What changes this quarter, what waits, and what it will cost when it comes due.

4
Converge

Each refresh, each failure, each expansion moves you closer to the standard. Over a few cycles, the environment simply becomes it.

A Standard, Not a Religion

If you run Hyper-V, Meraki, Fortinet, Lenovo, Google Workspace, or something else entirely, we can absolutely support it. The RTP is where we start when there is nothing to preserve and no constraint pulling us elsewhere. It is not a condition of working with us.

It also is not static. Products get added, and products get removed when they stop earning their place. We revisit this list as the market changes, and we will tell you plainly when something we previously recommended no longer makes the cut.

How Does Your Environment Compare?

We will inventory what you have, show you where it lines up with the platform, and give you a straight answer on what actually needs attention. No obligation.
