IT Support in Marietta, GA: Security-First Managed Services from COMNEXIA

Marietta businesses operating along the Barrett Parkway corridor, in the Town Center area, or near the Cobb County seat deal with the same IT pressure: endpoints that drift out of compliance, help-desk requests that pile up without a ticketing system, and security gaps that go undetected until something breaks. COMNEXIA has provided managed IT support to metro Atlanta and Cobb County businesses since 1991, with headquarters in Roswell roughly 15 miles north of Marietta on GA-120. Our approach starts with your security posture and builds outward, because patching a workstation that is already compromised solves nothing.

What "IT Support" Actually Means for a Marietta Business

Managed IT support from COMNEXIA is not a break-fix retainer. It is a documented, repeatable operating model built on four pillars: continuous remote monitoring and management (RMM) through NinjaOne, proactive patch deployment on a tested 30-day cycle, a staffed help desk with a ticketing queue in ConnectWise Manage, and monthly reporting that shows ticket volume, patch compliance percentage, and open vulnerabilities by severity. Every device COMNEXIA manages is enrolled in that RMM platform from day one of onboarding, not after the first incident.

Security Controls Embedded in Every Support Engagement

Because COMNEXIA is a security-first MSP, endpoint detection and response is not an add-on. SentinelOne EDR is deployed on every managed Windows and macOS endpoint during onboarding, with the policy set to Protect mode so threats are quarantined automatically rather than flagged for manual review. Identity is hardened through Microsoft Entra ID conditional access policies that enforce multi-factor authentication and restrict sign-ins to compliant, Entra-registered devices. For Marietta businesses running Microsoft 365, we also enable Defender for Business at the tenant level and configure attack surface reduction rules appropriate to office workloads.

Onboarding Process: What the First 30 Days Look Like

• Asset discovery scan across all subnets using NinjaOne to produce a full hardware and software inventory before any changes are made.
• Endpoint standardization: Windows devices brought to the current cumulative update baseline, bloatware removed, and a hardened configuration baseline applied via group policy or Intune MDM depending on directory setup.
• SentinelOne EDR agent deployed and policy confirmed in Protect mode within 48 hours of inventory sign-off.
• Microsoft Entra ID conditional access configured: MFA required, legacy authentication protocols blocked, named locations defined for the Marietta office network.
• Help-desk intake documented: escalation paths defined, business hours confirmed, on-site dispatch protocol agreed in writing.
• Baseline monthly report template delivered so the client can read patch compliance and alert counts without needing to log into any portal.

IT Support for Marietta Auto Dealerships

Cobb County has a dense concentration of franchised dealerships, and their IT environment is unlike a typical professional services office. A rooftop running CDK Global or Reynolds and Reynolds needs its dealer management system (DMS) workstations isolated from the guest Wi-Fi network, with DMS traffic treated as sensitive data in transit. Dealertrack users accessing financing and titling workflows require reliable, low-latency connectivity that a consumer-grade router cannot guarantee. COMNEXIA's support model addresses this directly: we document DMS server dependencies during onboarding, configure VLAN segmentation to separate DMS, sales, and service-drive traffic, and verify that every workstation touching customer financial data meets the FTC Safeguards Rule requirements effective since June 2023, including encrypted storage, access controls, and a written information security plan (WISP) on file.

The FTC Safeguards Rule applies to any dealership that qualifies as a financial institution under the Gramm-Leach-Bliley Act, which includes virtually all franchised auto dealers in Georgia. Non-compliance carries FTC enforcement risk. COMNEXIA's IT support engagement for dealerships includes a gap assessment against the Safeguards Rule's nine required program elements so ownership knows exactly where they stand before an audit request arrives.

Why Marietta Businesses Work with COMNEXIA Instead of a National Help Desk

A national help desk resets passwords and closes tickets. COMNEXIA's team in Roswell can dispatch a technician to a Marietta location the same business day for hardware failures or network outages that cannot be resolved remotely. That proximity matters when a service drive's lane management terminal goes down at 7 a.m. or a Marietta law firm loses access to its document management server before a filing deadline. Thirty-five years of operating in the Atlanta metro means our team already knows the Comcast Business and AT&T fiber circuits common in Cobb County, the building wiring constraints in older Marietta office parks, and the escalation contacts at local carriers.
