Penetration Testing in Alpharetta, GA: Find Your Gaps Before Attackers Do

COMNEXIA has provided managed IT and cybersecurity services to Alpharetta and metro Atlanta businesses from its Roswell, GA headquarters since 1991. Penetration testing is not a checkbox exercise for us. It is a structured, adversarial simulation that tells your leadership exactly which doors are unlocked, which credentials are reusable, and which network segments an attacker could reach after an initial foothold. If your business holds payment card data, protected health information, or consumer financial records under the FTC Safeguards Rule (16 CFR 314.4), a penetration test produces the documented evidence regulators and auditors expect to see.

What a Penetration Test Actually Covers for an Alpharetta Business

A penetration test is a time-boxed, authorized attempt to exploit real vulnerabilities in your environment using the same techniques a threat actor would use. COMNEXIA scopes each engagement around the assets that matter to your specific operation. For a North Fulton County professional services firm, that typically means external network testing against your public IP ranges, internal network testing from a simulated insider position, and web application testing for any client-facing portals. For an Alpharetta auto dealership running CDK Global, Reynolds and Reynolds, or Dealertrack, the scope also includes the dealer management system (DMS) network segment, the service lane tablets, and any remote-access paths your OEM or vendor uses to connect to your environment.

Why Alpharetta Dealerships Face Specific Penetration Testing Pressure

The FTC Safeguards Rule (16 CFR 314.4(f)(2)) requires financial institutions, including auto dealers that arrange financing, to conduct periodic penetration testing and vulnerability assessments. This is not optional guidance. The Rule specifies that penetration testing must occur at least annually and that vulnerability assessments must occur at least every six months or whenever there is a material change to your infrastructure. A dealership running CDK or Dealertrack that added a new F&I kiosk, changed a firewall rule, or migrated to a cloud-hosted DMS in the past year has experienced a material change. COMNEXIA documents each test against the 314.4 control set so your compliance officer has a defensible record.

COMNEXIA's Penetration Testing Process: Six Concrete Phases

• Scoping and Rules of Engagement: We document every IP range, domain, application, and system that is in scope, define blackout windows to avoid testing during month-end closes or F&I peak hours, and get written authorization before a single packet is sent.
• Reconnaissance: Passive and active discovery using open-source intelligence (OSINT) against your public footprint, DNS records, certificate transparency logs, and LinkedIn data to mirror what a targeted attacker would learn before touching your network.
• Vulnerability Identification: Authenticated and unauthenticated scanning of in-scope systems, cross-referenced with CVE data and vendor advisories, including Microsoft patch gaps that NinjaOne-managed endpoints may surface in monthly reporting.
• Exploitation: Manual, controlled attempts to exploit confirmed vulnerabilities, including credential stuffing against Microsoft Entra ID login pages, lateral movement testing within Active Directory, and privilege escalation attempts on endpoints protected by SentinelOne EDR to verify that behavioral detection fires as expected.
• Post-Exploitation and Impact Assessment: If a foothold is established, we document what data was reachable, which accounts could be compromised, and whether immutable backup repositories (3-2-1 architecture) were accessible from that position. Ransomware actors specifically target backup paths.
• Reporting and Remediation Guidance: You receive an executive summary with business-risk language and a technical findings report with CVSS scores, evidence screenshots, and named remediation steps, such as enforcing Microsoft Entra ID conditional access policies to block legacy authentication protocols or enabling tamper protection in SentinelOne.

How Penetration Testing Connects to Your Ongoing Security Posture

A penetration test produces a prioritized list of gaps. COMNEXIA closes those gaps within the managed services framework your business already relies on. Findings related to unpatched software feed directly into NinjaOne RMM patch management cycles. Findings related to weak authentication drive Microsoft Entra ID conditional access rule changes and phishing-simulation security-awareness training cadences. Findings related to detection gaps are validated against your SentinelOne EDR or Microsoft Defender for Endpoint configuration and reviewed by our 24/7 SOC. The test result becomes a work order, not a PDF that sits in a drawer.

For businesses that must also satisfy PCI DSS Requirement 11.4, CMMC Level 2 assessment preparation, or HIPAA Security Rule risk analysis obligations, COMNEXIA maps penetration test findings to the relevant control framework so that a single engagement produces evidence for multiple compliance requirements simultaneously.

Schedule Your Alpharetta Penetration Test

COMNEXIA serves Alpharetta, Roswell, Johns Creek, Milton, and surrounding North Fulton County businesses from our Roswell headquarters. If your last penetration test was more than twelve months ago, or if you have never had one, your environment has untested exposure.
