Network Security

The connective layer between users, cloud services, and the internet. Segmentation, Secure Web Gateway, and CASB — controlling what moves, where, and to what.

Common challenges

  • Flat networks with limited segmentation
  • No control or visibility over cloud app usage
  • Unfiltered internet access across the organisation
  • Legacy trust assumptions between network zones
  • Slow detection of lateral movement

Business risk

Without segmentation and traffic controls, a single compromised endpoint becomes an open path — to internal systems, cloud apps, and internet destinations alike.

How Mitigence helps

  1. 1Architecture review — segmentation model, firewall topology, traffic flows
  2. 2SWG deployment — filter and inspect outbound internet traffic
  3. 3CASB implementation — visibility and control over cloud and SaaS app usage
  4. 4Segmentation engineering — micro-segmentation, firewall policy hardening
  5. 5Configuration review — validate firewall rules, ACLs, routing policies
  6. 6Operational readiness — anomaly detection thresholds, monitoring integration

SWG — Secure Web Gateway

A Secure Web Gateway inspects and filters all outbound internet traffic — blocking malicious destinations, enforcing acceptable-use policy, and providing full visibility into what users and systems are reaching on the internet.

  • URL filtering and category-based access control
  • SSL/TLS inspection for encrypted traffic visibility
  • Malware detection and threat intelligence integration
  • Data loss controls on outbound web transfers

CASB — Cloud Access Security Broker

CASB sits between users and cloud services — giving you visibility into which cloud and SaaS applications are in use, who is using them, and what data is moving through them. It enforces policy on cloud app usage that firewalls alone cannot see.

  • Shadow IT discovery — identify unsanctioned cloud and SaaS usage
  • Access control for sanctioned cloud apps — conditional, policy-driven
  • Data security — prevent sensitive data being uploaded to unsanctioned services
  • Threat protection — detect compromised accounts and anomalous cloud behaviour

SWG and CASB are often deployed together as part of a broader SSE (Security Service Edge) architecture — alongside ZTNA for private application access. Mitigence designs and implements these as a cohesive program, not as standalone tools.
