Network Segmentation (VLAN/ACL) for NJ Medical & Small Offices

Keep PHI safe and systems fast. We design and enforce VLANs with tight ACLs, isolate guest Wi-Fi, prioritize VoIP, and document ports and labels—purpose-built for billers, small doctor offices, and clinics across New Jersey.

VLAN and ACL network segmentation for NJ clinics

Purpose-Built for NJ Billers, Small Practices & Clinics

We secure solo medical billers, small doctor offices, dental/PT/chiro, and multi-suite clinics around Edison, New Brunswick, East Brunswick, Woodbridge, Princeton, Metuchen, Somerset, and East Windsor.

Medical Billers

VPN/MFA to client EHRs, print/scan VLANs, least-privilege rules for uploads/clearinghouses.

Small Doctor Offices

PHI vs staff vs guest segmentation, DNS filtering, scanner shares, eFax routes.

Clinics & Imaging

PACS/DICOM flows, modality subnets, printer queues, VoIP QoS and camera isolation.

Clear Design. Enforced Policies. Proper Docs.

VLAN Plan & ACL Rulebook

  • VLANs: PHI/EMR, staff, guest, VoIP, printers/scanners, imaging/PACS, cameras/IoT
  • ACLs: deny-by-default; allow specific ports (e.g., 443 to EHR, 389/636 to AD, 104 for DICOM as needed)
  • DHCP/DNS: per-VLAN scopes; filtering & safe search for guest
  • QoS: EF for SIP/RTP; WMM profiles; bandwidth limits for guest

Firewall & Switch Configuration

  • SonicWall/Fortinet/Meraki/UniFi VLAN interfaces, inter-VLAN policies
  • 802.1Q trunks, access ports, voice VLANs, LLDP-MED for phones
  • AP SSIDs mapped to VLANs; guest portal & isolation
  • Logging, backups, and versioned config exports

Compliance & Audit Support

  • Network diagrams, port maps, and labeling conventions
  • Change log & SOPs for adds/moves/changes
  • Risk finding remediation notes for HIPAA reviews

Ongoing Support

  • 24/7 remote help; on-site support in NJ
  • Routine rulebook reviews as your practice grows
  • Emergency changes & hypercare during go-lives

Quick Planning Checklist

Inputs We’ll Ask For

  • EHR, eFax, clearinghouse, portal URLs/IPs
  • Phone system/provider details for VoIP
  • Printer/scanner models and share locations
  • Any imaging/PACS servers and modalities
  • Current switch/firewall/AP models & versions

Security Defaults

  • Deny-by-default between VLANs
  • MFA for VPN/admin; audit logging enabled
  • DNS filtering; block risky TLDs on guest
  • Backups of configs; role-based access

Typical Segmentation Packages

Biller Suite

PHI + staff + guest + printers VLANs; ACLs & DNS filter; port/label doc.

FAQs

Can we keep our existing IP scheme?
Often yes—we carve ranges per VLAN and adjust DHCP scopes to fit, then migrate devices with minimal downtime.
Will phones still work across VLANs?
Yes—voice VLANs, LLDP-MED, and ACL pinholes ensure SIP/RTP signaling and media pass while other traffic is blocked.
How do you test?
Rulebook validation, ping/trace to allowed destinations, EMR login tests, claim uploads, eFax send/receive, and call quality checks.
Do you provide rollback?
We back up configs and can revert quickly if needed. Changes are scheduled after hours with hypercare.
What about cameras and IoT?
They live on an isolated VLAN with strict ACLs—no access to PHI; NVR access is limited to authorized admin stations.
