Every open port is a doorway, and ransomware crews scan for them around the clock. This solution hardens the single point where your network meets the internet: firewall zoning, NAT and safe service publishing, intrusion prevention, first-line DDoS mitigation and internet-behavior audit — designed on open-brand security product categories, sized by users and real inspected throughput, with the limits stated out loud.
Four risks that sit at the internet edge of almost every company we assess:
Everything the internet can reach lives in its own zone; everything internal is segmented; only declared flows cross the firewall:
Architecture drawn by AtlasCommTech following carrier-grade network-security design practice. Diagram labels are kept in English for engineering clarity.
Why us: our founder spent 13 years inside the Huawei partner ecosystem delivering carrier networks, where the edge is attacked every single day. We design your edge with that assumption, not with optimism.
The solution is sized to your requirements and budget first — the same architecture can be delivered on several vendors' product lines. We help you choose by supply availability in your destination country, budget and your team's operating habits.
Six controls, one box family, one policy set — the whole edge becomes explainable in a single page of rules:
Firewalls are sized by what they inspect, not by what the datasheet celebrates — here is how the tiers differ:
| Scale tier | Typical site | What the design includes |
|---|---|---|
| ~50 users | Small office · single-site company | One desktop-class firewall with IPS and URL filtering on, NAT and a small DMZ if you publish anything, logs to the built-in store — one box, correctly configured, beats five gadgets. |
| ~200–500 users | Office building · school · hospital · hotel group HQ | Rack-class firewall — HA pair recommended — dual ISP egress, proper DMZ, segmented internal zones, dedicated log platform with retention to your regulator. |
| 1000+ users | Campus · government branch · data-heavy enterprise | HA firewall pair sized on inspected throughput with headroom, dedicated log and report platform, per-department policy, and — where public services justify it — a dedicated anti-DDoS appliance in front. |
The solution is built from these security product categories — the brand is chosen with you at design stage. Exact models depend on your bandwidth, enabled features and destination country — so we spec models after your requirements list, not before.
| Role | What it does |
|---|---|
| Next-gen firewalls | The core of the design: zoning, NAT, IPS, antivirus, URL filtering, VPN termination — desktop class to HA rack pairs, chosen by inspected throughput. |
| Log & report platform | Collects firewall and behavior logs, keeps them for your retention period, and turns them into the reports auditors actually accept. |
| Anti-DDoS appliances (when justified) | Dedicated scrubbing in front of heavily published services — for most companies the firewall's flood controls plus carrier support is the right-sized answer, and we say so. |
| Core / DMZ switches | Carry the segmented zones and connect published servers — the physical layer that makes the zone drawing real. |
| Signature & category licences | IPS signatures, antivirus databases and URL categories are living, licensed services — we state plainly which functions need them and for how long. |
| Endpoint protection (your side) | Not our box to sell here — but the gateway design assumes endpoints have their own protection and offline backups exist. We will not pretend the edge replaces them. |
