NexusSec.NexusSec deploys and hardens MikroTik RouterOS for businesses, branch sites and service providers across India. MikroTik delivers remarkable routing, VLAN and VPN capability for the price — but it ships with weak defaults and is frequently deployed insecurely. Correct configuration and hardening are the entire difference between excellent value and a serious liability.
What MikroTik is good at
- Routing — full BGP, OSPF and policy routing at a fraction of enterprise pricing
- VLANs and switching — capable segmentation on inexpensive hardware
- VPN — IPsec, WireGuard and other tunnel types for site-to-site connectivity
- Bandwidth management — granular queueing and traffic shaping
- Scripting and automation — powerful for repeatable multi-site deployments
As a hardened edge router, VPN concentrator or segmentation device behind a next-generation firewall, MikroTik is difficult to beat on value.
What it is not
MikroTik is not a next-generation firewall. It has no deep intrusion prevention, no sandboxing, no application-aware inspection and no threat-intelligence feed. Deploying MikroTik as your only security control at the internet edge leaves significant gaps. We commonly deploy it alongside a proper NGFW, or in layered designs where it handles routing and segmentation.
The hardening problem
MikroTik devices are frequently compromised in the wild, almost always because of the same avoidable issues. Our deployment standard addresses each:
- Management exposed to the internet — Winbox, SSH and the web interface must never be publicly reachable
- Default or weak admin credentials — renamed accounts, strong authentication, no default admin
- Outdated RouterOS — a defined update process, because published vulnerabilities are actively exploited
- Unnecessary services enabled — disable everything not in use
- No firewall rules on the router itself — input chain protection is essential, not optional
- SNMP with public community strings — restricted or disabled
What our deployment includes
- Hardware selection appropriate to throughput and port requirements
- Interface, VLAN and routing design with documented addressing
- Firewall rules on both forward and input chains, with least privilege
- VPN configuration for site-to-site and remote access
- Full hardening baseline as above
- Configuration backup, monitoring and update process
- Documentation and handover
