Cybersecurity Assessment in Brookhaven, GA

Cybersecurity Assessment for Brookhaven, GA Businesses

Most Brookhaven businesses running on unaudited networks have no clear picture of where an attacker could enter, which credentials are overprovisioned, or whether their backups would actually survive a ransomware event. COMNEXIA, headquartered in Roswell, GA and in business since 1991, delivers structured cybersecurity assessments that answer those questions with documented evidence, not guesswork. We serve companies throughout DeKalb County and metro Atlanta, including auto dealerships whose compliance obligations under the FTC Safeguards Rule (16 CFR 314.4) make an unassessed network a regulatory liability.

What a Cybersecurity Assessment Actually Covers

A cybersecurity assessment is a systematic review of your environment against a defined control framework, typically NIST CSF or CIS Controls, that maps every finding to a concrete remediation step. It is not a vulnerability scan dropped into a PDF. COMNEXIA's assessment covers six domains: identity and access controls, endpoint protection posture, network segmentation, data backup integrity, email and phishing exposure, and regulatory compliance gaps.

• Identity and access review: We audit Microsoft Entra ID (formerly Azure AD) for stale accounts, missing conditional access policies, and users who have not enrolled in MFA. We document every account with Global Administrator rights and flag any that violate least-privilege principles.
• Endpoint protection gap analysis: We verify whether SentinelOne EDR or Microsoft Defender for Endpoint is deployed, correctly licensed, and actively managed. An installed agent running in passive mode provides almost no protection, and we check agent health and policy enforcement across every managed endpoint.
• Backup survivability test: We validate whether your backups follow the 3-2-1 rule (three copies, two media types, one off-site or immutable copy) and whether a restore has been tested recently. Backups that have never been restored are not backups; they are hopes.
• Email and phishing exposure: We review your Microsoft 365 or Google Workspace anti-phishing policies, DMARC/DKIM/SPF records, and whether your staff has completed phishing-simulation security-awareness training in the past 12 months.
• Network segmentation review: We examine firewall rule sets and VLAN configurations to determine whether guest Wi-Fi, point-of-sale or DMS terminals, and corporate endpoints share the same broadcast domain.
• Regulatory compliance mapping: We map findings to the specific regulation that applies to your industry, the FTC Safeguards Rule for dealerships, PCI DSS for any business storing cardholder data, or HIPAA for healthcare-adjacent practices in the Brookhaven corridor.

Why Brookhaven and DeKalb County Businesses Need This Now

Brookhaven sits at the intersection of Peachtree Road and I-285 and hosts a dense mix of professional services firms, medical offices, and multi-rooftop auto groups. That concentration of high-revenue, credential-rich environments makes the area a recurring target for business email compromise and ransomware campaigns. Many organizations in the area inherited their network architecture from a previous IT provider with no formal handoff documentation, meaning unknown firewall rules, unpatched servers, and shadow admin accounts are common findings we surface in the first 30 days.

The Dealership Scenario: FTC Safeguards Rule and CDK or Reynolds Environments

Auto dealerships operating CDK Global, Reynolds and Reynolds, or Dealertrack dealer management systems have a specific compliance deadline problem. The FTC Safeguards Rule, updated and enforced since June 2023, requires dealerships to implement a written information security program with named controls, including access controls, MFA, encryption, continuous monitoring, and an incident response plan. Our assessment produces a written gap report that maps your CDK or Reynolds network segment directly to each of the nine required program elements under 16 CFR 314.4. We identify whether the DMS terminal network is isolated from your general office LAN, whether technician workstations have SentinelOne or Defender for Endpoint deployed, and whether your service loaner or F&I terminals are covered under your current backup and monitoring scope.

What COMNEXIA Delivers After the Assessment

Every assessment closes with a prioritized remediation report, not a raw spreadsheet. Findings are ranked by exploitability and business impact so your leadership can make budget decisions against real risk. If you engage COMNEXIA for ongoing managed services, remediation moves directly into our NinjaOne RMM environment for patch management, and 24/7 SOC monitoring through Microsoft Defender for Cloud or SentinelOne's managed detection and response tier is activated. Conditional access policies in Microsoft Entra ID are configured to enforce MFA on every login outside your trusted IP ranges. Phishing-simulation training is scheduled quarterly. Monthly reporting covers open findings, closed tickets, and patch compliance percentages so the assessment does not become a document that sits on a shelf.
