Services
Practical technology work for
companies that make things.
Every engagement is scoped honestly. No retainers you don't need. No upsells into products. Just clear work with clear deliverables.
Infrastructure &
Virtualization
Most shops are still paying VMware or Hyper-V licensing on hardware they own. TAPCAVE migrates environments onto open-source alternatives — Proxmox for virtualization, TrueNAS for storage, SmartOS or Triton for cloud-native workloads on bare metal.
Cloud repatriation is increasingly common: workloads that made sense in AWS or Azure five years ago are often cheaper and faster on a single well-specced server in your rack. We'll tell you honestly whether that's true for your situation.
- — VMware / Hyper-V migration planning and execution
- — Proxmox cluster setup and ongoing configuration
- — Storage design (ZFS, replication, snapshots) Illumos and TrueNAS
- — Cloud repatriation assessment and migration
- — Staff training and full runbook documentation
Manufacturing
Network Design
Production networks in most small manufacturing shops were never designed — they grew. Office traffic shares a segment with PLCs and HMIs. Machines with no authentication run on the same subnet as accounts payable. One employee clicking a phishing email becomes a plant floor problem.
TAPCAVE designs IT/OT segmented networks from scratch or restructures what you have. The deliverable isn't just working infrastructure — it's documentation that a new IT person can pick up on day one.
- — IT/OT network segmentation design
- — VLAN architecture and switch configuration
- — Firewall rules for production isolation
- — Network diagrams and change documentation
- — Security assessment of existing environments
Legacy System
Integration
That CNC machine from 2003 still runs fine. The problem is it only speaks a protocol nothing else understands, it's air-gapped from your ERP, and the engineer who set it up retired four years ago.
TAPCAVE builds the bridges — serial-to-Ethernet converters, protocol translators, custom read/write interfaces — that let aging equipment participate in modern workflows without a capital expenditure.
- — Legacy protocol bridging (RS-232, RS-485, Modbus, proprietary)
- — Custom data collection and integration interfaces
- — ERP and scheduling system connectivity
- — Network configuration for isolated equipment
Custom Application
Development
The quoting process lives in a spreadsheet nobody understands. Scheduling runs through a chain of emails. Job status requires calling someone. These aren't software problems — they're process problems that software can actually solve, if it's built to fit the process instead of forcing the process to fit the software.
TAPCAVE builds focused web applications that solve a specific problem well. Maintainable code, no framework mystery boxes, no vendor lock-in on your own business data.
- — Quoting and job costing tools
- — Scheduling and capacity planning applications
- — Workflow automation and approval routing
- — Integrations with legacy systems and ERPs
- — Internal dashboards and reporting
IT Architecture
& Assessment
If you're not sure what you have or what it would take to fix it, start here. TAPCAVE evaluates your existing environment — network, servers, security posture, vendor relationships — and gives you a straight answer about what's working, what's not, and what it would cost to change.
No product recommendations. No sales attached to the assessment. Just an honest evaluation from someone who's seen what goes wrong.
- — Infrastructure inventory and documentation
- — Security assessment (internal and external)
- — Vendor contract and licensing review
- — Prioritized remediation roadmap
- — Firewall rule audit and best practices implementation
Network Privacy
& Security
Consumer routers are surveillance devices with a DHCP server attached. Your ISP-provided router reports your traffic patterns to its manufacturer. The "smart" devices on your network have persistent connections to servers you've never heard of.
TAPCAVE installs and configures pfSense-based firewalls for small businesses and security-conscious home users — hardware you own, software you control, sensible defaults out of the box, fully documented so you understand what it does.
- — pfSense firewall hardware selection and configuration
- — DNS filtering and privacy configuration
- — VPN setup for remote access (WireGuard, OpenVPN)
- — IoT and guest network isolation
- — Ongoing monitoring and alerting setup
