Network Security & Firewalls Indianapolis | Monon Technology Services
Network Security — Indianapolis

Your Firewall Is Your First Line of Defense.
Most Aren't Configured That Way.

A firewall that ships with factory defaults isn't securing anything — it's creating a false sense of protection. We configure, segment, and document your network infrastructure so it actually does what it's supposed to do.

What We Secure

Every Layer of Your Network — Not Just the Edge.

Perimeter
Firewall Configuration
Factory defaults replaced with hardened rulesets — inbound and outbound traffic controlled, logged, and reviewed.
Internal
Network Segmentation
VLANs separating staff, guest, IoT, and server traffic — so a compromised device can't reach everything on the network.
Wireless
Secure Wi-Fi
WPA3, isolated guest networks, SSID segmentation, and rogue AP detection — no more single shared Wi-Fi password.
Remote Access
VPN & Remote Access
Secure site-to-site VPN and remote access solutions — replacing insecure RDP exposure with properly configured tunnels.
DNS
DNS Filtering
DNS-layer protection blocking known malicious domains, C2 servers, and inappropriate content before connections are made.
Monitoring
Traffic Logging & Review
Firewall log collection and periodic review — identifying unusual traffic patterns, unauthorized access attempts, and policy violations.
Network Segmentation

Why Flat Networks Are a Security Liability.

A flat network means every device can reach every other device. One compromised endpoint — a laptop, a printer, a smart TV — can potentially reach your servers, your financial data, and your entire operation. VLANs stop lateral movement before it starts.

VLAN 10
Staff Network
Workstations and laptops — access to business applications and internet, isolated from servers and IoT.
VLAN 20
Server Network
File servers, database servers, and internal applications — restricted access, heavily logged.
VLAN 30
Guest / Visitor
Internet access only — completely isolated from staff and server networks. No internal resource access.
VLAN 40
IoT / Devices
Printers, cameras, smart devices — internet access where needed, no lateral access to other segments.

What Proper Segmentation Prevents.

Ransomware SpreadIf ransomware hits a workstation on a segmented network, it can't reach your file server or other workstations — damage is contained.
Lateral MovementAttackers who compromise one device can't use it as a stepping stone to reach higher-value targets on the same network.
Guest Network AbuseVisitors, clients, or compromised personal devices on your guest network can't reach anything internal.
IoT Risk IsolationSmart TVs, cameras, and printers are notoriously insecure — segmentation keeps their compromise from becoming your breach.

When Did Your Firewall Last Get a Security Review?

Most firewalls are configured once and never revisited. Let's see where yours actually stands.
