Running a local ISP comes with enough challenges — worrying about network failures and blocking non-paying customers definitely shouldn’t be one of them. In this context, Splynx offers a suite of built-in tools that could quietly reshape your day-to-day network management, forgetting costly downtime and late-night troubleshooting once and for all. Here are 5 tips to keep you on the safe side so you can focus on growing your business — not just keeping it afloat.

1. Built-in and fully customizable RADIUS server for central admin access & customer authorization

You don’t need a lecture on what RADIUS does — you’re already in the know. With Splynx’s built-in RADIUS server, you’ve got a rock-solid base for centralized admin access control and automated customer authorization. If a customer doesn’t pay, they’re blocked or redirected to a special page automatically. The moment they pay, access is restored instantly.  It’s the kind of seamless control that ensures no one’s sneaking free internet on your dime. BTW, administrators can block customers manually as well.

For internal teams? Say goodbye to shared passwords and security headaches. Splynx lets you manage admin access to your equipment from one dashboard. Staff change? Update permissions in a snap — no need to reset passwords across hundreds of devices. It reduces the chaos of shared logins, tightening security without fanfare. Result?

2. Stay online no matter what with RADIUS failover

Networks, like any system, can stumble. Overall, in this business, you’re always one glitch away from a flood of support calls. What happens if your main server goes down (planned maintenance or a freak outage)?

With Splynx RADIUS Failover, you don’t have to find out the hard way; your customers won’t notice the problem. Authentication requests automatically switch to the backup server (active-active configuration maintains synchronization between servers every four hours to keep things current), ensuring backup systems always have current authentication data. Not as a cure-all but as a practical fallback.

For ISPs in rural areas or places where connectivity is a lifeline, this is a godsend. No more midnight heroics from your team — just reliable service that keeps your reputation intact.

Beyond emergency scenarios, RADIUS failover provides peace of mind through improved security posture. If your primary server faces a targeted attack, the redundant system ensures your network remains operational while you address the security concern, protecting both your infrastructure and your customers’ experience. It has already saved our clients many times.

3. Automatic device backups. Your time machine for fixes and change management record keeper

Network engineers every day deal with many routers that usually have different configurations. Mistakes happen — one tiny config tweak can trigger a domino effect, taking down a critical node and disrupting countless users. With Splynx SSH backup tool, every device configuration is automatically backed up and every change is tracked. So, you can precisely identify what changed (there’s side-by-side comparison between versions), who did it, and when — then roll back to a working setup in minutes, not hours. It’s like having a “rewind” button for your routers and other network equipment.

Configuration is straightforward in the Networking → Hardware →. Simply enter SSH credentials (login, password, communication port), specify the command to extract configurations (such as “export” for MikroTik or “show running-config” for Cisco), and set your preferred backup schedule. The system will securely connect to your devices, execute the specified commands, and store configuration snapshots for future reference.

Need more control? It’s possible to get a notification when a device goes down, helping you to see and resolve the issue as fast as possible. First, you need to create a notifications group. Let’s say that some “Engineers” groups are comprised of selected administrators. If equipment goes down for more than 5 minutes (for examle), they all get both email and portal notifications on the dashboard. And for the larger teams and better control, administrator permissions can be configured to control who can view, modify, or restore device configurations, ensuring proper change management protocols.

For ultimate efficiency, combine this with our newest Network Sites tool, which allows you to organize equipment, clients, and services into logical groups and manage them from one place. If a device goes offline, you instantly know who’s affected and can notify them in two clicks. This structure becomes invaluable during maintenance or outages, allowing you to quickly identify affected customers and send targeted mass notifications via email or SMS. This results in fewer angry calls, happier customers, and engineers who aren’t pulling their hair out.
