Network resilience: a stable and secure IT network

A vulnerable or unstable network is at the root of 60% of all cyber incidents. ZETA designs, secures and monitors your infrastructure, from network segmentation to 24/7 monitoring, so you can work undisturbed.

What makes a network truly resilient?

Resilience does not just mean that the network "works". It means that attackers cannot simply get through it, and that if something does go wrong, the damage stays limited.

Stable

No unexpected downtime, redundant connections, load balancing and SLA-driven uptime. Your employees work undisturbed.

Secure

Network segmentation, zero-trust access, encrypted connections and continuous monitoring for deviating traffic.

Verifiable

Full network visibility: who communicates with whom, which traffic deviates from the norm, which devices are active.

What does ZETA do for your network?

PREVENTION

Network segmentation & VLAN design

One large flat network is an attacker's dream: once inside, free rein everywhere. ZETA designs a segmented network architecture:

  • Separate VLANs for office, servers, OT/IoT and guests
  • DMZ for publicly reachable systems (web servers, mail gateways)
  • Isolation of critical systems (ERP, financial, production)
  • Micro-segmentation for sensitive environments

Result: an attacker who breaks into one segment cannot move laterally to the rest of your organization.

SECURITY

Next-generation firewall management

Setting up a firewall is one thing, keeping it up to date and correctly configured is a profession in itself. ZETA manages your firewall as a managed service:

  • Regular ruleset review and clean-up
  • Application-aware filtering (NGFW)
  • Intrusion Prevention System (IPS)
  • SSL inspection of encrypted traffic
  • Firmware updates and patch management

Works with all common firewalls

DETECTION

Network monitoring & logging

What you do not see, you cannot secure. ZETA implements full network visibility:

  • Central SIEM for network logs and events
  • Netflow analysis: see every conversation on your network
  • Anomaly detection
  • Automatic alerts on suspicious behaviour
  • Log retention in line with NIS2 / ISO 27001

CONTINUITY

SD-WAN & redundant connections

What if your internet line fails? Or a location loses its connection? ZETA designs for continuity:

  • SD-WAN for multiple locations
  • Automatic failover on line disruption
  • Load balancing across multiple providers
  • Prioritization of business-critical traffic (VoIP, ERP)
  • Encrypted site-to-site VPN tunnels

How a network assessment works

In four steps you get a complete picture of the current state of your network, and a concrete plan of action.

01

Inventory

All active devices, connections and network segments are mapped out.

02

Vulnerability analysis

We test your network architecture against best practices and detect misconfigurations.

03

Reporting

Findings by priority: critical, high, medium. With concrete recommendations per point.

04

Implementation

Optional: ZETA implements the improvements and takes over the ongoing management.

Do you know how resilient your network really is?

Most networks have grown without structural design. An assessment shows what can go wrong, before attackers discover it.
