⚠️

Business Problem

A 65-user manufacturing company with several remote corporate users needed secure access to on-premise office systems from home and field locations. Their Sophos XG firewall had never been properly configured, leaving remote access either completely blocked or dangerously open without authentication.

✅

Our Solution

We assessed the Sophos XG configuration, created role-based firewall rules for remote users, set up SSL VPN with Azure AD authentication, and implemented VLAN segmentation to isolate corporate traffic from guest networks — all within a 3-day engagement.

Project Plan

Firewall Audit

Reviewed existing Sophos XG ruleset, identified misconfigured any-to-any rules and unused policies. Documented current network topology across all VLANs.

VLAN Segmentation

Segmented corporate, guest, and IoT traffic into separate VLANs with inter-VLAN routing rules enforced at the firewall layer.

SSL VPN Setup

Configured Sophos SSL VPN with Azure AD SAML authentication. Deployed VPN client to all remote users via Intune — zero manual installs required.

Policy Hardening & Testing

Applied IPS policies, enabled WAF rules for internal web apps, and ran penetration tests to confirm no unintended external exposure remained.

Outcomes

Users with secure remote access

Full configuration and go-live

VLANs

Segmented network for full isolation

"Our client had a manufacturing floor with flat network architecture — everything on one VLAN. Inputiv redesigned the whole thing with Sophos XG, proper segmentation, and SSL VPN. Three days, 65 users, no downtime on the production line. Exactly what we needed."
