IT Consulting Services in Johns Creek, GA: Security-First Strategy from COMNEXIA

Johns Creek businesses operate in one of the fastest-growing commercial corridors in Fulton County, competing alongside firms clustered along McGinnis Ferry Road and Technology Park Atlanta. Growth creates IT complexity: multi-site networks, cloud sprawl, compliance obligations, and staff that outpaces existing infrastructure. COMNEXIA has provided IT consulting from its Roswell, GA headquarters since 1991, close enough to Johns Creek to conduct on-site assessments the same day. Our consulting practice starts with your security posture, because an architecture that cannot withstand a phishing campaign or a ransomware payload is not worth optimizing for speed.

What IT Consulting Means for a Johns Creek Business

IT consulting from COMNEXIA is a structured engagement, not an open-ended retainer where hours disappear. A typical engagement begins with a documented current-state assessment covering your Active Directory or Microsoft Entra ID configuration, firewall rule sets, endpoint inventory, and backup validation. We identify gaps against a defined baseline, such as CIS Controls v8 Level 1, and deliver a written remediation roadmap with prioritized action items, effort estimates, and named responsible parties. You receive a document you can act on independently or execute with us.

Security Posture Assessment: The Starting Point

Before recommending a single product, our consultants audit the controls already in place. That means reviewing Microsoft Entra ID conditional access policies to confirm multi-factor authentication is enforced for all users, not just administrators. It means checking whether SentinelOne EDR is deployed on every endpoint or only on company-issued laptops while contractor machines sit unmanaged. It means verifying that DNS filtering, email security (Microsoft Defender for Office 365 or equivalent), and privileged-access controls are configured, not simply licensed and idle.

Businesses in Johns Creek that handle sensitive customer data, including financial services firms near Medlock Bridge Road and professional services practices along State Bridge Road, often discover during this assessment that their Microsoft 365 tenants have legacy authentication protocols still enabled, a common vector for credential-stuffing attacks. Disabling legacy authentication in Entra ID and enforcing Conditional Access Policy baselines are concrete first-day actions our consultants document and, where engaged, implement.

IT Consulting for Auto Dealerships: CDK, Reynolds and Reynolds, and FTC Safeguards Compliance

COMNEXIA has specialized in automotive dealership IT for decades, and Johns Creek sits minutes from dealership clusters along Peachtree Industrial Boulevard and GA-400. Dealerships running CDK Global, Reynolds and Reynolds, or Dealertrack dealer management systems face a specific consulting challenge: those platforms require persistent network connectivity, role-based access controls, and audit-ready logging, and they must now comply with the FTC Safeguards Rule (16 CFR Part 314), which mandates a written information security program, annual penetration testing, and a designated qualified individual overseeing the program.

Our consulting work for dealerships includes mapping DMS data flows to identify where nonpublic personal information (NPI) travels, configuring network segmentation to isolate DMS servers from general office traffic, and producing the written inventory and risk assessment the Safeguards Rule requires. We document which CDK or Reynolds modules access customer financial data and whether those access paths are logged in a SIEM or centralized log management tool. These are audit artifacts, not checkboxes.

What COMNEXIA Delivers in a Consulting Engagement

• Current-state infrastructure assessment with documented findings mapped to CIS Controls v8 or the NIST Cybersecurity Framework, depending on your industry
• Microsoft Entra ID and Active Directory review covering conditional access policies, group policy objects, and privileged identity configurations
• Endpoint security gap analysis confirming SentinelOne EDR deployment status, patch currency via NinjaOne or ConnectWise Automate reporting, and endpoint standardization across device types
• Network architecture review including firewall rule audit, VLAN segmentation verification, and wireless security configuration
• FTC Safeguards Rule readiness assessment for auto dealerships, including written risk assessment, vendor access review, and incident response plan template
• Prioritized remediation roadmap with effort tiers (quick wins under 30 days, mid-term projects, and long-term architecture changes) and named technology recommendations
• Optional implementation support, where COMNEXIA transitions from advisor to hands-on executor under a managed services agreement

Why Johns Creek Businesses Choose COMNEXIA

Thirty-five years of operation means COMNEXIA has consulted through Windows NT migrations, the shift to cloud identity, and the current wave of AI-assisted phishing. That history produces consulting that accounts for technical debt common in established businesses, not only greenfield recommendations that ignore what is already running. Our Roswell headquarters puts a consultant physically in Johns Creek without travel overhead, which matters when an assessment requires hands-on access to server rooms or wiring closets that a remote-only firm cannot evaluate accurately.

We will schedule a scoped assessment, deliver written findings, and give you a prioritized plan your team can read and act on.
