How managed IT is delivered in Fairfax, Virginia
Fairfax is served from Brooklyn, in the same Eastern time zone. Monitoring runs 24/7 from Brooklyn, and so does emergency service. Our staffed help-desk hours are 4 a.m. to 11 p.m. Eastern time, seven days a week. The proposal states severe-incident escalation, authorized remediation and any other after-hours work. On-site commitments outside our on-site coverage (New York City, Long Island, Westchester, the Hudson Valley, North Jersey and Fairfield County, CT) are arranged in advance and sized to the engagement: a mostly remote engagement needs no dedicated on-site engineer, while an engagement that calls for regular presence, such as a standing on-site day or two each week, can include a dedicated engineer with a drive time generally under an hour once availability, location and the visit schedule are confirmed in the proposal. Hardware can ship pre-configured where the project permits remote setup. Confirm landlord access, circuit diversity, cabling and equipment space before approving a network change. Carrier options to check in Fairfax, Virginia include Verizon Fios, Spectrum Business and Comcast Business; availability, routing and installation dates must be verified at your address before a failover design is approved.
Who managed IT in Fairfax, Virginia is built for
Businesses we can support in and around Tysons, Reston, Merrifield, Chantilly and the City of Fairfax include federal IT and defense contractors on Deltek Costpoint, mortgage lenders and financial firms on Encompass, IT and cybersecurity firms on Salesforce, engineering and construction firms on Procore, medical practices on Epic, and health and life-sciences companies on Benchling. These are examples of business and application needs, not a list of local clients. We coordinate infrastructure, identity and integration with the application vendor, and identify any compliance requirements during discovery. Companies with an internal IT person can agree a split of responsibilities, systems and coverage hours before work begins.
Continuity planning for your Fairfax, Virginia business
Start with the systems your team cannot work without. Record the impact of a building power outage, a failed internet circuit, a compromised account and an unavailable application vendor. Then agree recovery priorities, an independent access path, protected backup copies and a test for each critical workflow. Controls reduce particular risks; they do not guarantee that an incident cannot happen.
Managed IT Services in Fairfax, Virginia: what NetSys delivers
Help desk and monitoring
- Unlimited help desk by phone, email and Teams, staffed by engineers rather than a ticket queue, with severe problems such as ransomware, systems down, no internet or email not working answered immediately by your dedicated engineer
- 24/7 monitoring of every server, workstation and firewall through NinjaOne RMM, with alerts an engineer acts on rather than forwards
- Patching and routine maintenance on the schedule your business sets, weekly for some clients and quarterly for others, with urgent fixes applied as needed in between
- Documentation of the whole environment in IT Glue, so the answer to 'what is that box' exists in writing
Security, built in
- ThreatDown managed detection and response with EDR agents on every device, not just servers
- Microsoft Defender for Business, Entra ID Conditional Access and multifactor authentication across the Microsoft 365 tenant
- Barracuda Email Protection in front of every mailbox, with SPF, DKIM and DMARC set correctly
- KnowBe4 security awareness training and simulated phishing for every user, on a recurring schedule
Backups, devices and vendors
- Datto SIRIS or Veeam backups with immutable off-site copies, and live restores run on the schedule in the agreement with the result sent to you
- Intune and Windows Autopilot device management, so a new laptop ships sealed and configures itself at first sign-in
- Vendor management: we deal with the ISP, the line-of-business software vendor and the landlord's building IT
- A quarterly technology review with a written roadmap and budget, run by the engineer who knows your environment
A 30-person government contractor in Reston
This planning example shows how we could scope the work. It is not a claim about a customer in this market or a measured result. For published customer work, see our case studies.
A 30-seat government contractor in Reston that grew out of its setup: Deltek Costpoint plus a dozen browser tools, an Exchange Online tenant with no multifactor authentication, a Meraki firewall out of support and a Comcast Business connection with no failover. The office manager has become the IT department by default and wants out. The owner has become the help desk and the office manager keeps the passwords in a spreadsheet.
- Quarterly technology review scheduled, with the first written roadmap and budget delivered at the 90-day mark
- Credentials, licenses and documentation collected from the outgoing provider, and what was actually deployed audited against what was being paid for
- Microsoft 365 tenant review: dormant accounts closed, legacy authentication switched off, Entra ID Conditional Access and multifactor authentication applied to every user
- Intune enrollment for every laptop and phone, with Windows Autopilot registration for new hardware and a compliance policy that gates access to email and files
- Cisco Meraki firewall and switches configured with segmentation for servers, staff, printers and guests, and a cellular failover circuit
- Cutover in stages over three to four weeks, with the old provider's access removed at the end, planned disruption agreed in advance and rollback checks documented
The help desk answers, the monitoring is watched by a person, the backups restore on schedule and every new hire is set up the same way. The business gets one number to call and a written picture of what is covered. Month to month, like every NetSys agreement.
Law office: Microsoft 365 with layered security and cloud-to-cloud backup
A 25-attorney firm in the greater New York metro was losing unbillable hours to an outdated file server and an email server that needed weekly attention. NetSys mapped the firm's matters and document workflows first, moved email to Exchange Online and documents to SharePoint and OneDrive in a matter-based structure over a weekend cut-over, layered anti-phishing protection, DNS filtering, multifactor authentication and endpoint protection across attorney devices, and set independent cloud-to-cloud backup of the whole tenant. The firm reported 82% fewer IT support incidents per month within two quarters and about 3.5 hours per attorney per week recovered from IT friction.

Compliance in Fairfax, Virginia: Virginia’s breach-notification statute and what sits on top of it
Virginia Code § 18.2-186.6 sets notice duties for covered breaches involving personal information and a risk of identity theft or fraud. The law distinguishes data owners from organizations maintaining another party’s data and includes exemptions and law-enforcement delay provisions. The service scope should identify the records, access controls, retention settings and incident evidence your business needs; your legal or compliance adviser determines which requirements apply. The managed agreement can include access reviews, patch reports, backup test results and a written incident response plan, with the evidence and responsibilities agreed in the scope. Discovery identifies missing records and assigns the documentation work. Applicable duties depend on the business, data, exemptions and contracts; your legal or compliance adviser determines which requirements apply.

What managed IT costs in Fairfax, Virginia
Managed IT is priced per user per month for a fully managed agreement, and the number moves with four things more than with headcount: how many servers you run, whether you need after-hours coverage beyond monitoring, how much compliance documentation you carry, and whether we are co-managing alongside an internal person or running everything. We quote from an assessment, not a phone call, and the agreement runs month to month. What belongs in the monthly fee versus what is billed separately is set out on our managed IT pricing page.
Who this fits, and who it does not
Best fit: 10 to 75 employees, one or two offices plus remote staff, already on Microsoft 365 or ready to move there, and either no internal IT or one person who is underwater.
Not a fit: businesses under five people, who are usually better served by the small-office baseline described in our five-person case study, or organizations over 250 seats, which need an internal team we can co-manage with rather than replace.

Managed IT Services in Fairfax, Virginia: FAQs
Do you support businesses in Fairfax, Virginia?
Yes. NetSys supports Fairfax, Virginia businesses remote-first from its only office, in Brooklyn. One month-to-month agreement covers the help desk, monitoring, security, backups and Microsoft 365. Windows PCs, Macs, Microsoft 365 and line-of-business applications such as Encompass and Salesforce are all supported, and problems on the vendor's side are taken up with the vendor directly. Onboarding starts with an assessment and a written scope, then a staged cutover, typically three to four weeks for a 20-seat office.
Is support in Fairfax, Virginia remote or on-site?
Remote-first. NetSys has one office, in Brooklyn, NY. Fairfax is served from Brooklyn, in the same Eastern time zone. The help desk, monitoring, security and Microsoft 365 work run remotely, with the help desk staffed seven days a week from 4 a.m. to 11 p.m. Eastern time and emergency service 24/7, and new hardware can ship pre-configured. Work that needs hands at an office in the City of Fairfax or Reston, such as hardware swaps, network closet work, new-hire setups and office moves, is a visit arranged in advance. How much on-site time an engagement includes is agreed before it starts: none for a mostly remote account, or a dedicated engineer where regular presence such as a standing on-site day or two each week is part of the scope. A drive time generally under an hour is an option subject to confirming engineer availability and your address. The proposal states the on-site arrangement and any travel in writing.
What does managed IT in Fairfax, Virginia include, and how is it priced?
One per-user fee pays for the help desk, round-the-clock monitoring, patching, ThreatDown MDR, Microsoft 365 and Intune administration, restore-tested backups and vendor calls. It is priced per user per month from an assessment, and server count, after-hours coverage beyond monitoring, compliance documentation and whether an internal IT person stays on move it more than headcount does. Calls to the vendors behind applications such as Procore and Epic are part of the fee. Planned visits to Fairfax, Virginia and any travel are quoted in the proposal. Hardware, licensing and projects such as migrations are quoted on their own, and our managed IT pricing page lists what the fee includes.
Can you work with our existing IT person?
Yes. That is a co-managed arrangement: your person keeps the relationships and the day-to-day, and we take monitoring, security, patching and after-hours coverage, with the split written into the agreement. Our co-managed IT page describes how the responsibility matrix is drawn.
Do we have to sign a long contract?
No. Every NetSys agreement runs month to month, with no long-term contract and no early-exit penalty. The scope, the responsibilities on each side and the monthly figure are written down before you sign.
How can IT support help with Virginia data-security requirements?
Virginia Code § 18.2-186.6 sets notice duties for covered breaches involving personal information and a risk of identity theft or fraud. The law distinguishes data owners from organizations maintaining another party’s data and includes exemptions and law-enforcement delay provisions. NetSys can help document the relevant systems, controls and incident evidence within an agreed scope; legal notification decisions remain with your authorized business and legal team.
