Cybersecurity Services in Roswell, Georgia

Cybersecurity Services in Roswell, GA, COMNEXIA

COMNEXIA has operated out of Roswell, Georgia since 1991, and cybersecurity has moved from a line item on our service list to the organizing principle of everything we deliver. Businesses in Roswell and across Fulton County face the same threat environment as enterprises in Buckhead or Midtown Atlanta: ransomware groups that target unpatched endpoints, credential-stuffing attacks against cloud portals, and phishing campaigns that bypass default email filters. What differs is that smaller and mid-size businesses here rarely have a dedicated security team to respond when something triggers an alert at 2 a.m. COMNEXIA fills that gap with specific, named controls, not a generic "layered security approach."

Endpoint Detection and Response: SentinelOne EDR on Every Device

We deploy SentinelOne EDR on every managed endpoint, including Windows workstations, servers, and macOS devices. SentinelOne uses behavioral AI to detect lateral movement and fileless attacks that signature-based antivirus misses entirely. When a threat is confirmed, the agent can autonomously quarantine the device and roll back malicious changes, shrinking the window between detection and containment without waiting for a human to approve each step. All telemetry feeds into our 24/7 SOC, where analysts triage alerts, correlate events across your environment, and escalate only confirmed incidents to your staff.

Identity and Access Controls Through Microsoft Entra ID

Stolen credentials are the entry point in the majority of breaches that hit Georgia businesses. We configure Microsoft Entra ID conditional access policies that enforce multi-factor authentication, evaluate sign-in risk in real time, and block login attempts from geographic locations or device states that fall outside your defined baseline. For businesses running Microsoft 365, we also enable Entra ID Protection to score each authentication attempt and trigger step-up verification or block access automatically. These are specific policy configurations we document, test, and hand off to you in monthly reporting, not settings applied once and forgotten.

Cybersecurity for Roswell Auto Dealerships: FTC Safeguards Rule Compliance

Automotive dealerships in the Roswell and greater Atlanta area that use CDK Global, Reynolds and Reynolds, or Dealertrack are required to comply with the FTC Safeguards Rule (16 CFR Part 314), which mandates a written information security program, access controls, encryption, continuous monitoring, and annual penetration testing for financial data. Non-compliance carries FTC enforcement risk and can void cyber-liability insurance coverage. COMNEXIA delivers the specific technical controls the Rule requires:

• Conditional access and MFA via Microsoft Entra ID, scoped to DMS and F&I portal accounts
• SentinelOne EDR on all dealership workstations and the server hosting your DMS connector
• Encrypted, immutable backups following the 3-2-1 rule: three copies, two media types, one off-site (cloud-based, geographically separate from your Roswell location)
• Network segmentation separating the sales floor guest Wi-Fi from the F&I workstations and DMS servers
• Quarterly phishing-simulation and security-awareness training campaigns for all dealership staff, with pass/fail reporting per employee
• A written Incident Response Plan naming roles, notification timelines, and escalation paths to satisfy Safeguards Rule Section 314.4(h)

Cloud Security with Microsoft Defender for Cloud

For Roswell businesses running workloads in Azure, we activate Microsoft Defender for Cloud, which continuously assesses your cloud configuration against CIS Benchmarks and Microsoft's own Secure Score recommendations. Misconfigured storage accounts, overly permissive network security groups, and unencrypted databases generate prioritized remediation tasks that our engineers resolve on a defined patch cycle managed through NinjaOne. Every change is logged and included in your monthly security report.

Phishing Simulations and Security Awareness Training

Technical controls fail when an employee pastes their credentials into a convincing lookalike page. We run monthly phishing simulations against your staff, using templates that mirror current lure styles: invoice fraud, IT help-desk impersonation, and shipping-notification attacks. Employees who click are immediately redirected to a short training module. Aggregate results, including click rates by department, are included in your monthly reporting so you can demonstrate a measurable improvement in human-layer risk over time.

Patch Management and Baseline Hardening

Unpatched software is the second most common attack vector after compromised credentials. We manage patch deployment through NinjaOne RMM, applying operating system and third-party application patches on a tested, scheduled cadence. Endpoints are standardized to a documented baseline configuration before onboarding, and any drift from that baseline triggers an automated alert. This is not a quarterly scan; it is continuous monitoring with a documented remediation workflow.

COMNEXIA serves businesses in Roswell, Alpharetta, Sandy Springs, Marietta, and across the greater Atlanta metro. If your organization needs to close a compliance gap, harden a dealership's DMS environment, or simply understand exactly which endpoints are unprotected today, call us at (877) 600-6550. We will start with a concrete review of your current endpoint, identity, and backup posture, not a sales presentation, and give you a written findings report before any engagement begins.
