Network Security
Secure the perimeter. Inspect every packet. Trust nothing by default.
Jiva Technologies designs, integrates, and supports network security architectures across data centre, campus, branch, and cloud — including next-generation firewalls, IDS/IPS, segmentation, secure remote access, SASE, ZTNA, and DDoS protection.
Palo Alto, Fortinet, Cisco, Check Point.
Zone, VLAN, VXLAN, and microsegmentation.
SASE, ZTNA, and per-application access.
What we deliver
Next-Generation Firewalls (NGFW)
Application-aware perimeter and internal firewalls with deep packet inspection, TLS decryption, IPS, and threat-intelligence integration on platforms including Palo Alto Networks, Fortinet, Cisco Secure Firewall, and Check Point.
Intrusion Detection & Prevention (IDS/IPS)
Signature and behaviour-based detection engines that inspect north-south and east-west traffic to block exploits, malware command-and-control, and lateral movement.
Network Segmentation & Microsegmentation
VLAN, VXLAN, and software-defined segmentation designs that contain breaches, isolate OT and IoT, and enforce least-privilege lateral access across data centre and campus networks.
Secure Remote Access & VPN
Modern remote-access architectures — SSL VPN, IPsec, and ZTNA — with MFA, device posture checks, and per-application access that replace legacy always-on VPN concentrators.
SASE & Zero Trust Architecture
Cloud-delivered SWG, CASB, ZTNA, and FWaaS unified as SASE, plus a Zero Trust roadmap covering identity, device, workload, network, and data pillars aligned to NIST 800-207.
DDoS Protection & DNS Security
Volumetric, protocol, and application-layer DDoS mitigation with cloud scrubbing, plus protective DNS to block phishing, malware, and command-and-control domains at the resolver.
Why teams call us
- Flat networks amplify breaches
Once inside, attackers move laterally in minutes because there is no segmentation between workloads or user zones.
- Legacy VPNs are the new perimeter
Always-on VPN trust exposes internal applications to any compromised laptop or unmanaged device.
- Encrypted traffic hides threats
Most traffic is TLS-encrypted, so firewalls without inspection miss modern malware and data exfiltration.
- Multi-cloud and branch sprawl
SaaS, IaaS, and branch offices each need their own security stack — cost and policy consistency drift over time.
Our approach
Layered network defence that inspects every packet, segments every workload, and treats no session as inherently trusted.
- Assess
Network architecture review, firewall rule-base audit, and segmentation gap analysis against Zero Trust and CIS benchmarks.
- Design
Target NGFW, SASE, and ZTNA architecture, segmentation blueprint, and phased Zero Trust roadmap tailored to the topology.
- Implement
Deploy NGFWs, IPS, segmentation, secure remote access, and DDoS protection in prioritised waves with planned change windows.
- Manage
Monitoring, rule-base hygiene, threat-intelligence updates, and periodic posture reviews as the network evolves.
End-to-End IT Integration and Support
From assessment and solution design through implementation, remediation, ongoing support, and lifecycle optimization.
Fix What's Broken — Remediation Sprints
Already running NGFWs, IDS/IPS, segmentation or ZTNA but rulebase bloat, false-positive noise, or coverage gaps are weakening protection? We run fixed-scope remediation sprints against your existing network security estate.
- Firewall rulebase audit, shadow-rule cleanup, and IPS signature tuning
- Segmentation and ZTNA policy gap-closure with least-privilege enforcement
- Post-incident hardening, TLS-inspection tuning, and auditor evidence pack
Support & Maintenance — AMC-Backed
Keep your NGFW, IDS/IPS, segmentation and ZTNA controls healthy after go-live — firmware, policy hygiene and vendor-TAC escalation under a Jiva AMC with contractual SLAs.
- L1/L2/L3 support for leading network security platforms and services
- Quarterly rulebase hygiene, IPS tuning and segmentation policy reviews
- Firmware, license renewal, vendor-TAC escalation and lifecycle refresh
