A Review After the First Month

We installed the Jabronifree suite on our factory network at the beginning of last month. The main goal was to isolate the M2M traffic between the assembly line robots and the central server, without slowing down production cycles. The first week was mostly about mapping all the existing connections and identifying which flows were critical and which could be restricted.

The hardware firewall arrived pre-configured for our Modbus and Profinet segments. The on-site engineer spent two days with our IT team to fine-tune the segmentation policies. We saw an immediate drop in unexpected broadcast traffic from the older PLCs. The dashboard showed a clear map of every device talking to the server, and we could finally see which machines were trying to reach external IPs during off-hours.

By the third week, we had blocked three unauthorized connection attempts from a contractor's laptop that was plugged into the network without approval. The alert system sent a notification to the security desk within seconds. Without the Zero Trust policy, that laptop would have had full access to the production database.

• Setup time: two days of on-site configuration with existing IT staff
• First blocked intrusion detected on day 12
• Network latency impact: less than 2 ms on critical M2M paths
• Dashboard visibility: all 47 devices mapped and categorized

The only friction point was the initial learning curve for the policy editor. The interface is terminal-style, which our network admin appreciated, but the shift engineer needed a quick walkthrough. After the first week, the daily reports became routine. We now have a weekly review of the access logs, and the system flags any new device that tries to join the network.
