MSP in Brookhaven, GA

MSP Atlanta: Managed IT Services for Brookhaven, GA Businesses

COMNEXIA has delivered managed IT services from its Roswell, GA headquarters since 1991, supporting businesses across DeKalb County and metro Atlanta, including Brookhaven's growing corridor of professional services firms, medical practices, and auto dealerships along Peachtree Road and Dresden Drive. A managed service provider handles the ongoing work of keeping your network secure, patched, and performing, so your internal staff does not have to. For Brookhaven businesses, that means a security-first posture backed by named platforms and documented processes, not a generic help-desk ticket queue.

What "Security-First MSP" Actually Means for Your Brookhaven Office

COMNEXIA leads every managed IT engagement with endpoint protection before layer-two connectivity and cloud migrations. Every managed endpoint runs SentinelOne EDR, which uses behavioral AI to detect ransomware execution patterns rather than relying on signature-based antivirus. Workstation and server patch cycles are managed through NinjaOne RMM, with critical patches deployed within 72 hours of release and third-party application patches (Adobe, Chrome, Java) on a defined weekly schedule. Microsoft Entra ID conditional access policies enforce multi-factor authentication and block sign-ins from non-compliant devices, which closes the credential-stuffing exposure that static VPN setups leave open.

DNS filtering through a dedicated DNS security layer blocks known-malicious domains at the resolver level before a payload reaches the browser. Email is secured with DMARC, DKIM, and SPF records configured and monitored, reducing spoofed-sender attacks that target Brookhaven accounting and HR staff. These are not optional add-ons. They are baseline controls applied at onboarding for every client.

The Onboarding Process: What Happens in the First 30 Days

Ambiguous onboarding is the reason most MSP relationships fail inside 18 months. COMNEXIA runs a documented four-phase onboarding for every new Brookhaven client. Phase one is a full network and asset discovery using NinjaOne's agent deployment, producing a named inventory of every managed endpoint, server, firewall, and switch. Phase two is baseline security hardening: Entra ID conditional access configuration, SentinelOne deployment and policy tuning, and DNS filtering profile assignment. Phase three is help-desk integration, giving your staff a ticketing portal with assigned priority tiers. Phase four is a written 30-day report showing asset count, patch compliance percentage, and any open vulnerabilities ranked by CVSS score. Your team sees exactly what was found and what was fixed.

Monthly Reporting and Ongoing Help-Desk Support

Every COMNEXIA client receives a monthly executive summary generated from NinjaOne data. It includes patch compliance rates by device group, SentinelOne alert count with resolution notes, and a list of any endpoints that fell out of compliance during the period. Help-desk requests are submitted through a ticketing system, and each ticket is categorized by severity on intake. Network-down and server-offline events are treated as critical and escalated immediately. Password resets and software installation requests are handled within standard business hours. Ticket history is available to your team through the client portal, so you can audit response history without asking COMNEXIA for a report.

Auto Dealerships in Brookhaven and the FTC Safeguards Rule

COMNEXIA serves auto dealerships throughout metro Atlanta, and Brookhaven's proximity to dealership clusters along Peachtree Industrial and Buford Highway makes this relevant to the local market. Dealerships using CDK Global, Reynolds and Reynolds, or Dealertrack operate DMS platforms that process non-public customer financial information, which places them under the FTC Safeguards Rule (amended 2023). The Safeguards Rule requires a written information security program, designation of a qualified individual, periodic risk assessments, and technical controls including encryption, MFA, and continuous monitoring.

COMNEXIA's managed IT stack addresses each of those requirements directly. Entra ID MFA satisfies the multi-factor authentication mandate. SentinelOne EDR logs provide the continuous monitoring documentation the rule requires. NinjaOne patch records serve as evidence of vulnerability management. For dealerships on CDK Global's environment, COMNEXIA coordinates network segmentation so DMS traffic is isolated from general office traffic, reducing the blast radius of any intrusion. Reynolds and Reynolds environments receive the same segmentation review at onboarding. This is not general compliance consulting. It is specific technical configuration tied to the regulation your dealership already has to meet.

Why Brookhaven Businesses Call COMNEXIA Instead of a Generalist MSP

• 35 years of continuous operation from Roswell, GA, with institutional knowledge of metro Atlanta's network infrastructure vendors and carriers
• SentinelOne EDR and NinjaOne RMM deployed as standard baseline, not upsold after onboarding
• Documented FTC Safeguards Rule alignment for auto dealership clients on CDK Global, Reynolds and Reynolds, and Dealertrack
• Microsoft Entra ID conditional access configured at onboarding, not flagged as a future project
• Monthly patch compliance and security alert reports delivered in writing with device-level detail
• Help-desk ticketing with defined escalation tiers and client-accessible ticket history

If your Brookhaven business is running on reactive IT support, an unclear patch schedule, or a DMS platform without network segmentation, the exposure is specific and measurable. Call COMNEXIA at (877) 600-6550 to schedule a network assessment. The assessment produces a named asset inventory and a prioritized list of open vulnerabilities. That list, not a sales deck, is where the conversation starts.
