Network Security
Segmentation, NGFW, IPS, ZTNA and DNS security - the network layer of a coordinated cyber defence.

About network security
The network is still the layer that catches what the endpoint missed. Telappliant designs network security around segmentation, next-gen firewalls, intrusion prevention, ZTNA and DNS-layer security - all integrated with our managed SOC for 24/7 response.
Segmentation is the foundation. We split your network into zones - corporate, guest, OT, IoT, PCI, regulated data - with firewall control between them. A compromise in one zone does not become a compromise of the whole estate.
NGFW with IPS handles east-west and north-south traffic with deep inspection, application control, sandboxing and SSL decryption where appropriate. Threat-intelligence feeds keep signatures current.
ZTNA replaces traditional VPN for hybrid workforce. Users authenticate to specific applications rather than the whole network, with continuous posture checks - if a device falls out of compliance, access drops.
DNS security catches the early phase of most attacks - command-and-control, phishing destinations and known-bad infrastructure - at the DNS resolver, before the connection is even attempted.
