Managed IT Services in Marietta, GA: Security-First Support for Cobb County Businesses

COMNEXIA has delivered managed IT services from its Roswell, GA headquarters since 1991, and Marietta businesses sit squarely in our primary service corridor along the GA-400 and I-75 corridors. We are not a generalist break-fix shop that added an MSP tier. Security controls are the foundation of every engagement, and every tool we deploy, every policy we write, and every endpoint we touch is configured to reduce your attack surface before we worry about uptime metrics.

What Managed IT Actually Covers for a Marietta Business

Managed IT is a flat-rate, proactive model where COMNEXIA owns the ongoing health and security of your environment rather than billing you per incident. For a Marietta law firm, accounting practice, or auto dealership, that means we monitor every endpoint 24/7 through our RMM platform (NinjaOne), push Microsoft patch updates on a tested schedule within 14 days of release to align with CIS Benchmark patch cadence, and close tickets through a documented help-desk workflow in ConnectWise Manage so nothing falls through the cracks. You receive a monthly report that maps open vulnerabilities, patched items, and endpoint compliance status, not a one-page summary with green checkmarks.

The Security Stack We Deploy, Named

Generic antivirus is not part of our stack. Every managed endpoint runs SentinelOne EDR, which provides behavioral AI detection and automated rollback of ransomware-encrypted files, even offline. Identity is governed through Microsoft Entra ID with conditional access policies that block authentication attempts from non-compliant devices or unexpected geographies. Multi-factor authentication is enforced via Microsoft Authenticator, not optional. DNS filtering runs through Cisco Umbrella, blocking malicious domains before a connection is established. For businesses in Marietta that handle sensitive data across a VPN, we configure split-tunnel policies explicitly to route internal traffic through the corporate gateway while keeping general browsing off it.

Onboarding: The First 30 Days

We follow a documented onboarding process, not an ad-hoc one. During week one, we conduct a full network discovery using NinjaOne's asset inventory to catalog every device, OS version, and installed application. Week two covers endpoint standardization: machines running Windows 10 21H2 or earlier are flagged for upgrade, non-standard software is documented and either approved or scheduled for removal, and NinjaOne agents are deployed to every managed node. Week three focuses on policy configuration: SentinelOne policies are set to Protect mode (not Detect), Entra ID conditional access baselines are applied, and Cisco Umbrella DNS policies are linked to your Active Directory groups. Week four is a handoff review with your designated contact, walking through the monthly reporting template and escalation paths so you know exactly who calls whom when an alert fires at 2 a.m.

Managed IT for Marietta Auto Dealerships

Auto dealerships in the greater Marietta and Cobb County area face a regulatory layer that most businesses do not: the FTC Safeguards Rule, which since June 2023 requires dealerships to maintain a written information security program, encrypt customer data in transit and at rest, implement MFA for any system accessing customer financial records, and conduct annual penetration testing. COMNEXIA's managed IT program is built around these requirements. We support CDK Global, Reynolds and Reynolds, and Dealertrack DMS environments, and we configure network segmentation so DMS traffic runs on isolated VLANs, separate from the guest Wi-Fi and service loaner device networks. When CDK or Reynolds pushes an update, our NinjaOne maintenance windows are scheduled outside peak sales hours, and a rollback snapshot is confirmed before the update runs. Our documentation package satisfies the Safeguards Rule's requirement for a documented asset inventory and access control log.

Help Desk and Escalation

Every ticket enters ConnectWise Manage and is categorized by priority. A workstation that will not boot is not in the same queue as a request to install Adobe Reader. Tier-1 issues are addressed by remote technicians first; issues requiring physical presence in Marietta are dispatched from our Roswell office. You do not reach a national call center that has never seen your environment. The technician who answers your ticket has access to your full asset history and configuration notes in ConnectWise.
