Cybersecurity Services in Newnan, Georgia

Cybersecurity Services for Newnan, GA Businesses

Newnan and Coweta County businesses face the same threat actors targeting Atlanta's metro corridor, but often without the dedicated security staff to stop them. COMNEXIA, headquartered in Roswell, GA and operating since 1991, delivers enterprise-grade cybersecurity to Newnan-area companies that need real protection, not a checkbox. Every engagement starts with a security-first posture: endpoint detection, identity controls, and monitored response before anything else.

What Cybersecurity Actually Means for a Newnan Business

Cybersecurity is not a firewall and a prayer. For a Newnan manufacturer, logistics firm, medical practice, or auto dealership, it means knowing that every endpoint is monitored for behavioral anomalies, every login is gated by multi-factor authentication, and every backup can survive a ransomware event. The specific problems COMNEXIA solves are concrete: credential theft via phishing, ransomware encrypting shared drives, unpatched Windows servers exploited over the weekend, and compliance gaps that trigger regulatory penalties.

Endpoint Detection and Response (EDR/MDR)

COMNEXIA deploys SentinelOne EDR across client endpoints. SentinelOne uses AI-driven behavioral analysis to detect threats that signature-based antivirus misses, and its Storyline feature maps every process, file, and network connection involved in an attack so analysts can see the full kill chain, not just an alert. For organizations that need full managed detection and response coverage, COMNEXIA pairs SentinelOne with 24/7 SOC monitoring, meaning a human analyst reviews high-confidence alerts around the clock, not just during Newnan business hours.

Identity and Access Controls with Microsoft Entra ID

Compromised credentials are the leading entry point in business email compromise and ransomware attacks. COMNEXIA configures Microsoft Entra ID conditional access policies that evaluate every sign-in against signals including device compliance, IP location, and user risk score before granting access to Microsoft 365 or line-of-business applications. Phishing-resistant MFA (Microsoft Authenticator or FIDO2 keys) is enforced at the policy level, not left as an opt-in. Privileged accounts are scoped with role-based access controls so a compromised helpdesk credential cannot escalate to domain admin.

Backup Architecture That Survives Ransomware

COMNEXIA implements a 3-2-1 backup strategy: three copies of data, on two different media types, with one copy stored off-site and immutable. Immutable means ransomware cannot encrypt or delete the backup, even if it reaches the backup server. Recovery point objectives and recovery time objectives are tested on a documented schedule, not assumed. A Newnan business that has never run a restore test does not know whether its backup actually works.

Security Awareness Training and Phishing Simulation

Most breaches start with a human clicking a link. COMNEXIA runs phishing-simulation campaigns that send realistic lure emails to client staff and track click rates by department. Employees who click receive immediate in-context training, and aggregate results feed into monthly reporting so management can see which teams need additional coaching. This is not a once-a-year compliance video; it is a continuous program that measurably reduces click rates over time.

Auto Dealerships in Newnan: FTC Safeguards Rule Compliance

Dealerships in Coweta County that operate dealer management systems (DMS) through CDK Global, Reynolds and Reynolds, or Dealertrack are subject to the FTC Safeguards Rule (16 CFR Part 314), which has been fully enforced since June 2023. The rule requires a written information security program, access controls, encryption of customer financial data in transit and at rest, multi-factor authentication, and annual penetration testing or vulnerability assessments. COMNEXIA's cybersecurity stack directly addresses each of these requirements: Microsoft Entra ID conditional access satisfies the access-control and MFA mandates, SentinelOne EDR supports continuous monitoring requirements, and immutable off-site backups address the data-recovery provisions. COMNEXIA documents these controls in a format that can be presented to an FTC examiner or a dealer group's compliance officer.

Patch Management and Endpoint Standardization

Unpatched systems are the second most common ransomware entry point after phishing. COMNEXIA uses NinjaOne RMM to enforce patch policies across Windows, macOS, and third-party applications (Chrome, Adobe, Java), with patching windows defined per client and compliance reports delivered monthly. Endpoints are standardized to a vetted configuration baseline so that a new workstation at a Newnan dealership or professional services firm is not deployed with default settings that leave admin shares open.
