Perimeter
Defence &
Network Visibility

The network perimeter has expanded far beyond the traditional edge firewall, but perimeter security remains the most important layer of defence. Modern NGFW platforms inspect application-layer traffic, enforce identity-based policies, decrypt SSL/TLS, and integrate with threat intelligence feeds to block attacks in real time.

Network Detection & Response (NDR) platforms complete the picture โ€” using machine learning to analyse east-west traffic flows within your network, detecting lateral movement, C2 communication, and anomalous behaviour that perimeter firewalls never see.

The CSIT Advantage

๐Ÿ”ฌ
Policy-First Design
We design firewall policies based on your business application flows, not open rules that get tightened later. Zero Trust from Day 1.
๐Ÿค–
AI-Driven NDR
Darktrace and Vectra AI use unsupervised machine learning to establish a baseline of normal network behaviour โ€” detecting deviations that indicate compromise instantly.
๐Ÿ”
SSL/TLS Inspection
Over 80% of malware now hides in encrypted traffic. We configure SSL inspection with certificate trust chains and privacy policy exceptions for financial and medical sites.
๐Ÿ“‹
Rule Base Hygiene
We perform firewall policy audits identifying bloated, redundant, and overly permissive rules, delivering a cleaner, more secure rule base that's easier to audit.
โšก
HA & Redundancy Design
All firewall deployments designed as active-passive or active-active HA clusters, eliminating the firewall as a single point of failure in your network architecture.
๐Ÿท๏ธ
Managed Firewall Service
We operate firewalls under your brand as a managed security service, 24ร—7 monitoring, rule change management, threat feed updates, and monthly reporting.

How We Work

1
Network Assessment
Map traffic flows, review existing rules, identify gaps, and define security zones.
2
NGFW Design
Design zone model, HA topology, security policies, and SSL inspection architecture.
3
Deployment
Install, configure, and validate NGFW in maintenance window with rollback plan.
4
NDR Integration
Deploy NDR sensors, connect to SIEM, and baseline network behaviour for 2 weeks.
5
Managed Operations
24ร—7 monitoring, rule change management, threat intelligence updates, and reporting.
