Cybersecurity Services in Newnan, GA

Cybersecurity Services for Small Business in Newnan, GA

Newnan and Coweta County businesses face the same threat actors targeting Atlanta's financial corridors and automotive corridors along I-85, yet most operate without the security controls that enterprise IT teams take for granted. COMNEXIA, headquartered in Roswell, GA and operating for 35 years, delivers structured, security-first managed cybersecurity to Newnan-area businesses, including auto dealerships, professional services firms, and healthcare-adjacent practices. This page details exactly what that service includes, how it is configured, and what regulations it helps you satisfy.

Why Newnan Businesses Are a Target Worth Protecting

Coweta County's growth along the Newnan Crossing and Ashley Park corridors has added hundreds of small and mid-size businesses that process payment cards, store customer PII, and run cloud-connected systems. Ransomware groups actively target businesses with fewer than 100 employees precisely because those businesses often run unpatched endpoints, share credentials across applications, and lack 24/7 monitoring. A single successful phishing attack against an employee at a Newnan dealership or medical billing office can expose thousands of customer records and trigger regulatory penalties under the FTC Safeguards Rule or PCI DSS.

Endpoint Detection and Response: SentinelOne EDR on Every Machine

COMNEXIA deploys SentinelOne Endpoint Detection and Response (EDR) across every managed endpoint. Unlike traditional antivirus that relies on signature databases, SentinelOne uses behavioral AI to detect and roll back ransomware execution in real time, including fileless attacks that never write a traditional payload to disk. Every agent reports to a centralized console where COMNEXIA's security operations team monitors alerts around the clock. When a threat is confirmed, automated response can isolate the affected machine from the network within seconds, containing lateral movement before it reaches your server or DMS environment.

Identity Protection with Microsoft Entra ID Conditional Access and MFA

Stolen credentials are the leading initial access vector in small-business breaches. COMNEXIA configures Microsoft Entra ID (formerly Azure Active Directory) with conditional access policies that evaluate sign-in risk before granting access to any application. Policies are scoped so that a login attempt from an unrecognized device or an unusual location triggers a step-up authentication challenge or blocks access entirely. Multi-factor authentication is enforced for every user, including shared service accounts that are frequently left unprotected. For Newnan dealerships running Reynolds and Reynolds or Dealertrack through a browser, this means a compromised password alone cannot open your DMS to an attacker.

FTC Safeguards Rule Compliance for Auto Dealerships

Under the FTC Safeguards Rule (16 CFR Part 314), auto dealerships that arrange financing are classified as financial institutions and must maintain a written information security program, conduct risk assessments, and implement specific technical safeguards including access controls, encryption, and continuous monitoring. COMNEXIA builds that program around documented controls: SentinelOne EDR satisfies the continuous monitoring requirement, Entra ID conditional access satisfies access control requirements, and encrypted off-site backups satisfy the data protection requirement. If your dealership runs CDK Global, Reynolds and Reynolds, or Dealertrack, COMNEXIA maps your existing DMS access patterns to the Safeguards Rule requirements and closes the gaps.

Immutable Off-Site Backups Following the 3-2-1 Standard

COMNEXIA enforces a 3-2-1 backup architecture: three copies of your data, on two different media types, with one copy stored off-site in an immutable format that cannot be encrypted or deleted by ransomware. Backup jobs are verified with automated restore tests, not just completion logs. For a Newnan dealership or professional services firm, this means your critical files, QuickBooks data, and DMS exports can be recovered to a clean state even if every local machine is compromised.

Phishing Simulation and Security Awareness Training

COMNEXIA runs ongoing phishing simulation campaigns against your employee roster, sending realistic but controlled phishing emails to identify who clicks, who enters credentials, and who reports the attempt. Employees who fail a simulation receive immediate, in-context training rather than a quarterly slide deck. Click rates and completion rates are tracked in monthly reports delivered to management, giving you documented evidence of a training program that satisfies FTC Safeguards Rule Section 314.4(e) and PCI DSS Requirement 12.6.
