Co Managed IT Services in Sandy Springs, GA

Co-Managed IT Services in Sandy Springs, GA | COMNEXIA

If your Sandy Springs business already has an internal IT person or small team, co-managed IT services let that team offload specific functions to COMNEXIA without surrendering control of your infrastructure. COMNEXIA has operated from Roswell, GA since 1991, giving us 35 years of hands-on experience supporting businesses across Fulton County, including auto dealerships running CDK Global, Reynolds and Reynolds, and Dealertrack environments. The model is straightforward: your staff handles what they know best, and COMNEXIA fills the gaps with licensed engineers, enterprise-grade tooling, and a documented security-first process.

What Co-Managed IT Actually Means for a Sandy Springs Business

Co-managed IT is not a vague "partnership." It is a contractually defined division of IT responsibilities between your internal staff and COMNEXIA. Before work begins, we conduct a documented onboarding assessment that maps every endpoint, server, firewall, and cloud tenant in your environment. From that inventory, we build a shared responsibility matrix: your team retains day-to-day user support and application ownership; COMNEXIA owns security monitoring, patch management, backup verification, and escalation engineering. Each role is written down so nothing falls through the cracks at 2 a.m.

Security Controls Your Internal Team Gets Immediately

Most internal IT teams at Sandy Springs companies manage five to fifteen things at once and lack time to maintain a strong security posture. COMNEXIA layers in controls that take weeks to configure correctly on your own.

• Endpoint detection and response (EDR): We deploy SentinelOne EDR on every managed endpoint, configured with behavioral AI detection and automatic threat isolation, not just signature-based antivirus.
• Remote monitoring and management (RMM): NinjaOne or ConnectWise Automate monitors every device in real time, enforces patch compliance on a defined cycle (critical OS patches within 72 hours of release), and generates the monthly reporting your leadership team can actually read.
• Identity and access controls: We configure Microsoft Entra ID conditional access policies that block sign-ins from non-compliant devices or unexpected geographies, reducing credential-stuffing risk without requiring your IT person to hold a Microsoft certification.
• DNS-layer filtering: Cisco Umbrella or a comparable resolver blocks malicious domains before a connection is established, which matters when employees visit phishing URLs in Sandy Springs office Wi-Fi or on the road.
• Backup and recovery verification: We test restores on a documented schedule. Backup alerts that nobody checks are not a backup strategy.

Co-Managed IT for Sandy Springs Auto Dealerships

Auto dealerships in and around Sandy Springs face regulatory pressure that most other small businesses do not. The FTC Safeguards Rule (16 CFR Part 314), updated and enforced as of June 2023, requires dealers to maintain a written information security program, designate a qualified individual to oversee it, conduct annual risk assessments, and implement specific technical safeguards including encryption, multi-factor authentication, and access controls on customer financial data. If your dealership runs CDK Global or Reynolds and Reynolds as its dealer management system (DMS), those platforms hold exactly the customer nonpublic personal information (NPI) the Safeguards Rule covers.

COMNEXIA's co-managed model is well-suited to this compliance need. Your dealership's existing IT contact handles day-to-day DMS user requests; COMNEXIA owns the Safeguards Rule technical controls: network segmentation between the DMS environment and general office traffic, MFA enforcement on Dealertrack and CDK portals through Microsoft Entra ID, SentinelOne EDR on every service-lane and finance-office workstation, and the documented annual risk assessment your qualified individual must sign off on. We do not write a policy and disappear. We produce the evidence your regulator would ask to see.

The Shared Help-Desk and Ticketing Structure

Under a co-managed agreement, COMNEXIA does not replace your help desk. We integrate with it. We use a shared ticketing workflow so your IT staff can escalate a ticket directly to COMNEXIA Tier 2 or Tier 3 engineers without re-explaining the issue. If your team uses ConnectWise Manage or a similar PSA, we can work within that existing instance or mirror ticket data into ours. Your internal person stays the face of IT for your employees; COMNEXIA handles the cases that exceed their bandwidth or expertise, such as a SentinelOne alert requiring forensic triage or a Microsoft Entra ID configuration change that requires tenant-level permissions.

Monthly Reporting That Means Something

Every month, COMNEXIA delivers a written report covering patch compliance rates by device group, open versus closed tickets by category, EDR threat detections and their resolutions, and backup job success rates. If your internal IT team needs to show leadership that the environment is healthy and the Safeguards Rule controls are functioning, that report is the documentation they use.
