IT Consulting in St. Louis, MO

St. Louis organizations call in consultants when a decision is bigger than a ticket: a server that loses support in January 2027, a defense contract that brings NIST SP 800-171 with it, a merger, or a move out of a Clayton tower. NetSys turns those decisions into scoped, priced projects and carries them out remotely from Brooklyn.

The short answer

NetSys offers IT consulting to St. Louis organizations: technology and security assessments, priced multi-year roadmaps, moves to Microsoft 365 and Azure, HIPAA and NIST SP 800-171 readiness, designs for new networks and office relocations, acquisition due diligence and virtual CIO reviews. Every engagement comes with a written scope, a fixed price, milestones, acceptance checks and a documented handover. Consultants work with you remotely from Brooklyn and never travel to St. Louis. Help desk support after the project is a separate managed agreement, not part of the consulting fee.

How IT consulting is delivered in St. Louis

Every phase of a St. Louis engagement runs remotely, which keeps it quick to schedule and inexpensive to run. Interviews with leadership and department heads happen over Teams. Technical discovery pulls data straight from the systems: Microsoft 365 and Entra ID reports, Intune inventory, firewall exports, server and storage statistics, backup logs and license records. If a design depends on physical space, such as the network closet in a new suite, your facilities lead takes the photos and measurements we specify, since NetSys does not send consultants to the building. Deliverables are written documents with costs and dates, reviewed with you on a call, and each project closes with documentation your staff or another provider can use. Assessment, design and integration work is coordinated from Brooklyn, with meetings and change windows stated in Central time. The project has agreed milestones, acceptance checks and a handover. Ongoing monitoring and help desk require a separately defined managed scope.

Defense and aerospace suppliers: NIST SP 800-171 readiness

Boeing's fighter work in north St. Louis County, including the F-47 contract announced in March 2025 and a $1.8 billion expansion near Lambert, Scott Air Force Base with USTRANSCOM and Air Mobility Command, and the National Geospatial-Intelligence Agency's new western headquarters pull smaller St. Louis firms into defense supply chains. Contracts carrying DFARS 252.204-7012 require NIST SP 800-171 Revision 2 controls for controlled unclassified information. On July 13, 2026 the Department of War suspended CMMC Phase 2, the third-party Level 2 certification that was to begin November 10, 2026, while a reform task force reviews the program; Level 1 and Level 2 self-assessments, a current SPRS score and affirmation and the DFARS clause still apply. Our consulting work scopes the CUI boundary, builds a GCC High or segmented enclave, writes the system security plan and prepares an honest score. This is general information, not legal advice.

Cloud migrations and the Windows Server 2016 deadline

Extended support for Windows Server 2016 runs out on January 12, 2027, and Windows 10 lost support in October 2025, so many St. Louis offices are deciding this year what replaces an aging server closet. Our assessment sorts each workload into one of four paths: retire it, move it into Microsoft 365, move it to Azure, or replace the server. File shares usually go to SharePoint and Teams with permissions redesigned along the way. Line-of-business applications are tested in Azure, or moved to the vendor's hosted version where it is mature. Domain controllers give way to Entra ID with Intune. Every migration has a cost model comparing three years of cloud spending with a hardware refresh, a weekend cutover plan, a rollback path and restore tests before the old system is switched off.

Office moves, mergers and due diligence in St. Louis

Real estate decisions turn into IT projects. A firm moving from downtown to Clayton, consolidating floors in a Maryland Heights office park or opening a branch in St. Charles County needs circuits ordered months ahead, a network designed before the low-voltage contractor starts, and phones, printers and Wi-Fi working on the first morning. We write the move plan, specify equipment, coordinate the carrier and contractor and run the cutover remotely over a weekend. Acquisitions are the other common project. Ahead of signing, a NetSys diligence report examines the target's identity platform, tenant, endpoints, backups, security tooling, licensing and contracts and ranks what needs a price or a condition. After the deal closes we plan the tenant-to-tenant move, identity consolidation and device re-enrollment, each weekend with its own rollback plan.

Virtual CIO reviews for St. Louis leadership teams

For organizations without a senior IT leader, our virtual CIO service provides one part time. Each quarter we review the environment's health, the risk register, upcoming renewals and the budget with your leadership, and update a roadmap that names projects, costs and target dates. Between reviews the same engineer is available for decisions that touch technology: whether to renew the copier lease or move printing to the cloud, how to answer a hospital customer's vendor security questionnaire, which Microsoft 365 licensing tier fits, what cyber insurance underwriters will ask at renewal, and when the next firewall and laptop refresh is due. The roadmap is written so it stays useful whether your staff, NetSys or another provider carries it out.

Published case study

Large international food importer: the whole platform rebuilt in Azure

An extreme weather event knocked out power and connectivity to a food importer's building and cut a 120-person, three-warehouse business off from suppliers and clients worldwide for days. NetSys ran a two-week assessment of every workload with recovery objectives per system and a cost model comparing an on-premises refresh with Azure, designed a landing zone with hub-and-spoke networks and Entra ID Conditional Access, lifted the SQL environment to Azure SQL Managed Instance, rebuilt file shares on Azure Files, published applications through Azure Virtual Desktop, connected the warehouses by VPN, and layered Defender for Endpoint, Exchange Online Protection and immutable backups on top. The migration took ten weeks with a weekend cut-over.

What IT consulting costs in St Louis

Consulting is priced by the project or by the review rather than by the hour: an assessment has a fixed price based on the size of the environment, a migration is quoted from the workload inventory, and virtual CIO advisory is a monthly figure that scales with how many reviews and decisions a year you need. What moves the number is the number of systems and sites, the compliance standard in play and whether we are also managing the environment afterwards. Every quote is written from discovery, and the terms run month to month.

How the monthly fee is built

Who this fits, and who it does not

Best fit: 10 to 150 employees, a decision on the table that involves cloud, an office move, an acquisition, a compliance program or a system nobody trusts, and leadership that wants options with numbers rather than a sales deck.

Common Questions

IT Consulting in St Louis: FAQs

How does IT consulting work for St. Louis organizations?

Engagements run in three stages. A scoping call and written proposal fix the deliverables, schedule and price. Discovery and design follow, with interviews over Teams, data pulled from your systems and draft findings reviewed on a call. Implementation, if you want it, runs in agreed change windows in Central time with acceptance checks and a rollback plan. Nobody from NetSys travels to the St. Louis office; physical steps are completed by your staff or contractor from our checklist. Each project closes with acceptance sign-off and the documentation to run what was built.

How do I choose an IT consulting firm in St. Louis?

Judge a consultant by the paperwork and the people. Before signing, ask for an example assessment and a sample migration runbook, and check that every recommendation has a cost and a date. Find out whether the people writing the plan will be the ones executing it, whether they take referral fees on hardware or software, and how they handle security in a design. A consultant who tells a St. Louis firm to delay a purchase, and explains why, is usually one who can be trusted with the rest.

Which consulting services do you offer in St. Louis, and what drives the price?

The menu runs from assessments and multi-year plans to cloud migrations, office-move network designs, CUI and HIPAA readiness, pre-acquisition reviews and a part-time CIO. Billing follows the deliverable rather than the clock: assessments are fixed-fee and scaled to how many users and systems you have, migrations are quoted once every workload is counted, and the virtual CIO service is a set monthly amount. Sites on both sides of the river and the compliance standard involved also move each price.

Can you prepare our SPRS score and system security plan?

Yes. We start with a scoping exercise that identifies where controlled unclassified information enters, lives and leaves your environment, because a tight boundary makes everything after it cheaper. Then we assess the 110 NIST SP 800-171 Revision 2 requirements, write the system security plan and a plan of action for the gaps, and calculate the score using the DoD assessment methodology for you to submit and affirm in SPRS. Remediation can follow as a project or under a managed agreement.

What happens after the roadmap is delivered?

That is your decision. Your own staff can carry out the projects, NetSys can deliver them one at a time at fixed prices, or we can take over running the environment under a managed agreement. If you keep the virtual CIO service, we revisit the plan every quarter against new contracts, hires, threats and the budget, so it stays a working document. The plan is written so it never depends on NetSys staying involved.
