Cybersecurity Services in Kennesaw, GA

Cybersecurity Services for Small Business in Kennesaw, GA

Kennesaw businesses face the same threat actors targeting companies across metro Atlanta, but most lack the in-house security staff to stop them. COMNEXIA has delivered security-first managed IT from its Roswell, GA headquarters since 1991, and we work with small and mid-size businesses throughout Cobb County, including auto dealerships on Barrett Parkway and professional services firms near Town Center. Our cybersecurity program is built on named, auditable controls, not marketing promises.

What Cybersecurity Services Actually Means for a Kennesaw Business

Cybersecurity is not a product you purchase once. For a Kennesaw small business, it means running endpoint detection and response on every workstation and server, enforcing identity controls so stolen passwords alone cannot open your network, maintaining offsite backups that ransomware cannot reach, and having a 24/7 SOC reviewing alerts while your staff focuses on operations. COMNEXIA packages those controls into a managed program so the configuration, monitoring, and response work sits with our team, not yours.

Endpoint Detection and Response: SentinelOne and Microsoft Defender for Endpoint

Antivirus signatures miss modern fileless attacks and living-off-the-land techniques. COMNEXIA deploys SentinelOne EDR or Microsoft Defender for Endpoint, depending on your existing Microsoft licensing, on every managed endpoint. Both platforms use behavioral AI to detect lateral movement, privilege escalation, and ransomware encryption in real time. When a threat is confirmed, automated response can isolate the affected machine from the network in seconds without waiting for a technician to intervene. Agents are deployed and version-controlled through our NinjaOne RMM platform, so patch status and sensor health appear in the same monthly report you receive.

Identity Security with Microsoft Entra ID

Compromised credentials remain the leading initial access vector in Georgia small-business breaches. COMNEXIA configures Microsoft Entra ID conditional access policies that require MFA for every sign-in and block authentication attempts from high-risk locations or non-compliant devices. We also enable Entra ID Protection, which scores sign-in risk in real time and can force a password reset or block access automatically when anomalous behavior is detected. For businesses running hybrid environments, those policies extend to on-premises resources through Entra ID Application Proxy, closing a gap that attackers commonly exploit.

Compliance Requirements Kennesaw Businesses Cannot Ignore

Specific industries operating in Cobb County carry legal cybersecurity obligations, and COMNEXIA's program is built to address them directly:

• Auto dealerships (FTC Safeguards Rule, 16 CFR 314.4): Franchised and independent dealers that handle consumer financial information must maintain a written information security program, designate a qualified individual, conduct risk assessments, and implement access controls and encryption. COMNEXIA has direct experience with CDK Global, Reynolds and Reynolds, and Dealertrack environments. We document the required controls, configure encryption in transit and at rest, and produce the annual reporting your qualified individual must review.
• Businesses that store payment card data (PCI DSS): PCI DSS v4.0 requires multi-factor authentication for all access to the cardholder data environment, network segmentation, and quarterly vulnerability scans. Our program addresses each of those requirements with named controls rather than checkbox attestation.
• Healthcare-adjacent businesses (HIPAA): If your Kennesaw business handles protected health information, HIPAA's Security Rule requires technical safeguards including access controls, audit controls, and transmission security. COMNEXIA maps our EDR, Entra ID, and backup configurations directly to those requirements.

Immutable Backups and Ransomware Recovery

A working backup is your last line of defense when prevention fails. COMNEXIA implements a 3-2-1 backup strategy: three copies of data, on two different media types, with one copy stored offsite in an immutable format that cannot be altered or deleted by ransomware, even if it reaches your backup server. Retention policies and recovery point objectives are documented before deployment, and we run quarterly restore tests so recovery time is a known number, not a guess during an incident.

Security Awareness Training and Phishing Simulation

Human error causes most successful breaches. COMNEXIA runs managed phishing simulation campaigns that send realistic test phishes to your employees, track click rates by department, and automatically assign short remediation training to anyone who interacts with a simulated threat. Over a 90-day baseline period, most Kennesaw clients see measurable reductions in click rates as employees learn to recognize credential-harvesting emails, fake invoice attachments, and spoofed vendor requests.

24/7 SOC Monitoring

Alerts generated at 2 a.m. on a Saturday do not wait until Monday. COMNEXIA's managed SOC reviews telemetry from SentinelOne or Defender for Endpoint, Entra ID sign-in logs, and Microsoft Defender for Cloud around the clock. When a confirmed incident requires action, our team responds directly rather than routing a ticket for you to action in the morning.
