A Smart Group Company
Defend your network perimeter, segment traffic, and detect threats in real time with enterprise-grade security appliances and platforms.
Network security is the first line of defence against cyber threats. DEL designs, supplies, and implements network security solutions that protect organisations from unauthorised access, malware, and advanced persistent threats.
Engagements run from edge firewall refreshes to full segmentation programmes — policy design, deployment, tuning and rule documentation delivered by NSE-certified engineers, with 24/7 monitoring and incident response available under AMC.
SME applicability: a single UTM appliance brings firewall, antivirus, web filtering and VPN to a small office in one supported box.
Firewalls, detection, secure access, application delivery and Wi-Fi — the full network security stack.

Five scenarios we harden most often.
Deploy NGFW at internet edge to inspect all inbound and outbound traffic for threats.
Segment ministry/department networks to contain breaches and enforce access policies.
Enable staff to work securely from any location with VPN and zero-trust access.
Defend public-facing services against volumetric and application-layer DDoS attacks.
What authorisation, certification and process add up to.
Fortinet (Bangladesh).
NSE-trained technical engineers.
Security architecture and policy design.
Deployment, tuning, and rule configuration.
Direct authorisations across firewall, application delivery and secure access.

A sample of what this solution draws from — the full catalogue carries live specifications and datasheets.
Case studies where network security was the delivered solution.
Passed the group’s global cyber-audit with zero critical findings; lateral movement between OT and IT is now blocked by policy.
One policy board governs all entities; phishing attempts are quarantined before reaching inboxes.
Branch interconnect latency dropped by half and link failures are now detected in seconds, not hours.
Whitepapers and posts that pair with this solution.
Describe your perimeter and compliance drivers — our NSE-certified engineers return an architecture, BOM and phased rollout plan.
