Practical help across your IT infrastructure.

Secure Infrastructure & Topology

Sound security begins with a sound topology — the way your computers, network, and applications are laid out, connected, and separated. ISMC designs and refines that structure, then adds the controls that protect it, so security is built into how your IT works rather than bolted on afterward.

• Secure design & architecture — laying out your computers, network, and applications so the right things can talk to each other, and the wrong things can't.
• Segmentation & microsegmentation — isolating critical assets so a single problem can't spread across your organization.
• Firewalls & access controls — selecting, configuring, and validating the firewalls, proxies, and gateways that enforce your design.
• Remote-access & rule-base review — securing VPNs and connections to the outside world, and clearing out the stale, overly permissive rules that quietly widen your exposure.
• Infrastructure as Code (IaC) — defining your network and its security rules in version-controlled files, so the topology can be reviewed before it's built and reproduced reliably as you grow, rather than hand-configured and left to drift.

Built for today's perimeter-less reality: the same discipline now extends far beyond a single appliance. ISMC designs Zero Trust and microsegmentation strategies, host-based and distributed firewall policies, and encrypted "TLS-everywhere" architectures that protect cloud and hybrid networks where the old network edge no longer exists.

Security Assessments & Audits

You can't fix what you can't see. ISMC delivers a clear, prioritized picture of your security posture — separating the issues that genuinely expose you from the noise — so your investment goes where it matters most.

• Network & infrastructure risk assessment — a structured review of your architecture, controls, and exposure.
• Topology & configuration audits — verifying that what's deployed matches what you intended, and closing the gaps.
• Compliance gap analysis — mapping your controls against the frameworks your customers and regulators expect.
• Policy & procedure review — checking that the rules your people follow actually match the security your computers, applications, and network need.
• Prioritized remediation roadmap — a plain-language plan ranked by risk and effort, not a 200-page report you'll never read.

Measured against today's threat model: assessments evaluate Zero Trust readiness, how much of your traffic still travels in cleartext, segmentation and lateral-movement risk, your cloud and identity (MFA) posture, and the security of your Infrastructure-as-Code definitions — not just yesterday's perimeter.

Self-Hosted Infrastructure & IaC

The tools for running your own infrastructure have never been better — or more secure when set up well. ISMC helps you stand up modern, self-hosted services using current Infrastructure-as-Code practices, so your systems are reproducible, portable, and under your control rather than scattered across someone else's cloud.

• Containerized services with Docker — packaging applications so they run the same way everywhere, update cleanly, and stay isolated from one another.
• Caddy reverse proxy & automatic HTTPS — a modern, secure front door for your services, with TLS certificates issued and renewed automatically.
• Self-hosted collaboration with Nextcloud — file sharing, calendars, and document collaboration you own, instead of renting per seat.
• Email & core services — standing up and securing reliable email and the other building blocks your organization runs on every day.
• Defined as code — every piece captured in version-controlled configuration, so the whole stack can be reviewed, reproduced, and rebuilt on demand.

Security comes built in: containers are isolated, traffic is encrypted by default, and because the topology lives in code, every change is reviewable and every environment is reproducible.

Training & Education

Security shouldn't depend on a single outside expert. ISMC's founder has spent a career not only doing the work but teaching it — writing published training material and leading courses for companies and government teams. We bring that same approach to your team, so the knowledge stays with you.

• Custom on-site training — tailored to your stack, your team's level, and the threats you actually face.
• Network security & topology courses — from fundamentals to advanced design, configuration, and troubleshooting.
• Security-awareness sessions — practical, jargon-free training for non-technical staff who are often the real attack surface.
• Knowledge transfer engagements — pairing with you or your staff to introduce the newest advancements and technologies, such as A.I., drones, and Infrastructure as Code (IaC) for dynamically scalable infrastructure topologies.

Keeping pace with where security is heading: training covers Zero Trust principles, microsegmentation, encryption and TLS, Infrastructure as Code, and the practical use — and risks — of A.I. on both sides of the firewall.

Home Networks & Entertainment

Homes have quietly become small data centers. Your washer, dryer, refrigerator, thermostat, doorbell, and speakers are all online now, and most television comes through streaming rather than a cable box. When something won't connect — or you simply want it set up safely and made easy to use — ISMC can help.

• Home network & Wi-Fi — reliable coverage in every room, set up securely so your devices and personal data stay protected.
• Smart home & IoT — getting appliances, cameras, thermostats, doorbells, and speakers connected and working together, without leaving your home exposed to the internet.
• Streaming & entertainment — cutting the cable cord, setting up streaming services and smart TVs, and making the whole thing simple to use.
• Privacy & parental controls — keeping your network private and giving you control over what reaches the kids.
• Patient, plain-language help — friendly one-on-one troubleshooting and guidance, explained without the jargon.
