Managed Detection And Response in Alpharetta, GA

Managed Detection and Response in Alpharetta, GA | COMNEXIA

Why Alpharetta Businesses Need More Than Antivirus

Alpharetta's technology corridor along GA-400, home to hundreds of fintech, healthcare, and automotive businesses, draws sophisticated attackers who know traditional antivirus stops at the perimeter. Managed Detection and Response (MDR) closes the gap by combining SentinelOne EDR or Microsoft Defender for Endpoint with a 24/7 Security Operations Center (SOC) that hunts, isolates, and remediates threats in real time. COMNEXIA has delivered security-first managed IT from its Roswell, GA headquarters since 1991, and our MDR practice is built around the specific compliance pressures and DMS platforms that Alpharetta-area businesses actually run.

What COMNEXIA's MDR Service Delivers

MDR is not a product you install and forget. It is a continuous process: telemetry collection from every endpoint, correlation of alerts in a SOC, analyst investigation, and verified remediation before damage spreads. Here is exactly what that process looks like inside your environment:

• Endpoint Detection and Response (EDR) deployment: We deploy and configure SentinelOne Singularity or Microsoft Defender for Endpoint on every workstation, server, and laptop in scope. Policies are tuned to your environment, not left at default, so alert noise stays low and genuine threats surface immediately.
• 24/7 SOC monitoring and threat hunting: Our SOC analysts review telemetry around the clock. When SentinelOne flags a suspicious PowerShell execution or lateral movement attempt, an analyst validates it within minutes and isolates the affected endpoint before ransomware can propagate.
• Microsoft Entra ID conditional access and MFA enforcement: Identity is the most common attack vector. We configure Entra ID conditional access policies that block sign-ins from untrusted locations, require phishing-resistant MFA, and revoke sessions the moment an account shows anomalous behavior.
• Microsoft Defender for Cloud integration: For Alpharetta businesses running Azure workloads, we connect Defender for Cloud to your SOC feed so cloud misconfigurations and runtime threats are visible in the same dashboard as endpoint alerts.
• Immutable, off-site backups following the 3-2-1 rule: MDR contains active threats; backups resolve them if containment is incomplete. We configure three copies of critical data on two media types with one off-site, air-gapped or immutable copy so ransomware cannot encrypt your recovery point.
• Phishing-simulation security-awareness training: Simulated phishing campaigns run monthly against your staff. Users who click receive immediate remedial training. Click rates and completion metrics appear in your monthly report so you can track improvement over time.
• Patch management via NinjaOne RMM: Unpatched endpoints are the second-most-common ransomware entry point. NinjaOne deploys OS and third-party patches on a defined schedule, and our team reviews patch compliance in every monthly reporting cycle.

MDR for Alpharetta Auto Dealerships: FTC Safeguards Rule Compliance

Auto dealerships operating in the Alpharetta and North Fulton County market face a concrete regulatory deadline under the FTC Safeguards Rule (16 CFR Part 314.4), which requires a written information security program, continuous monitoring, and annual penetration testing for any dealership that handles consumer financial data. If your store runs CDK Global, Reynolds and Reynolds, or Dealertrack as your dealer management system, those DMS environments touch nonpublic personal financial information on every deal jacket. COMNEXIA's MDR service deploys SentinelOne EDR on the workstations connected to your DMS, monitors authentication logs from your Entra ID tenant, and produces the audit-ready incident response documentation that FTC examiners and your compliance officer need. We have experience with the network segmentation requirements that separate DMS traffic from general office traffic, which is one of the most commonly cited gaps in FTC Safeguards audits of Georgia dealerships.

MDR and PCI DSS for Businesses Handling Card Data

Alpharetta retailers, restaurants, and service businesses that process payment cards are subject to PCI DSS requirements including continuous log monitoring (Requirement 10) and malware protection (Requirement 5). COMNEXIA's SOC satisfies both by forwarding SentinelOne and Defender for Endpoint telemetry into a centralized log platform, retaining 12 months of log history, and generating the quarterly reports your QSA will request at assessment time.

Why Businesses in Alpharetta Choose COMNEXIA

COMNEXIA has operated from Roswell, GA for 35 years, which means our engineers know the Alpharetta business community, its compliance environment, and its infrastructure firsthand. We are not a national call center routing tickets overseas. When SentinelOne isolates an endpoint at your Alpharetta dealership or office at 2 a.m., a SOC analyst investigates the alert, and if physical response is needed, our North Metro Atlanta team is close. Every new MDR client goes through a documented onboarding process: asset discovery, EDR deployment, Entra ID policy review, and a baseline threat assessment before your first full month of monitoring begins.
