01 / 08 — Banking & Financial Services

Infrastructure that holds under audit pressure and incident pressure simultaneously.

Case Study · Banking Apex Commercial Bank

"Nexora did what two previous integrators couldn't — they delivered a PCI-compliant, active-active data centre that our QSA was satisfied with on first review. The failover tests they ran during commissioning gave our board the confidence to sign off on the new core banking platform."

02 / 08 — Healthcare

Clinical networks where patient data privacy and care continuity are both absolute.

Hospitals and diagnostic networks carry a dual mandate that no other sector faces: ironclad ePHI protection under HIPAA, and 24/7 availability of the clinical devices that keep patients alive. We separate these concerns cleanly from day one.

// The challenge// Our answer
Imaging equipment, EMR, and guest WiFi on same VLAN
Clinical, staff, IoT, and guest segments — fully isolated
Unpatched medical devices creating attack surface
Device identity NAC — fingerprinting + VLAN enforcement
Ransomware targeting EMR backups without immutable copy
3-2-1 immutable backup — 4h RTO, 15min RPO
Dead zones in ICU and radiology causing WiFi drop-outs

03 / 08 — Manufacturing & Industrial

OT/IT convergence done right — security without stopping the production line.

Modern manufacturing is inseparably connected: ERP to SCADA, sensors to cloud analytics, remote engineers to PLCs. We architect the convergence correctly the first time — applying the Purdue model, OT-aware firewalls, and live cutover sequencing that keeps production running.

// The challenge// Our answer
Flat OT/IT network — engineer laptop reaches PLC directly
Purdue L0–L4 segmentation with OT-DMZ enforcement
Remote maintenance vendor access unlogged, persistent
PAM jump server — time-limited, fully session-recorded
IIoT sensors reporting to cloud through corporate LAN
Dedicated IIoT VLAN with anomaly-detection monitoring
Ransomware shutting down plant floor for 72+ hours
OT-specific IR playbook — 6h RTO tested, air-gapped backup

Case Study · Manufacturing Bashundhara Industrial Group

"We had a ransomware attempt on our plant network that would have cost us 72 hours of production. Because Nexora had segmented our OT environment and implemented the runbook, our team contained it in under 4 hours — without stopping a single production line."

04 / 08 — Government & Defense

Air-gapped, sovereign, and hardened against nation-state threat actors.

Government agencies and defense contractors face the most demanding security environments on the planet — nation-state APTs, classification requirements, supply chain threats, and zero tolerance for data sovereignty violations. Our cleared engineering team has built and operated classified infrastructure with a zero-incident record.

// The challenge// Our answer
Data residency obligations violated by cloud-default architectures
Sovereign-cloud and on-premises hybrid with data never leaving jurisdiction
Nation-state APT campaigns targeting ministry networks
APT-focused threat hunting retainer — TTP-mapped detection rules

05 / 08 — Telecom & ISP

Carrier-grade infrastructure built for the scale, speed, and threat profile of ISPs and telecoms.

Internet Service Providers and telecoms live at the perimeter of every attack vector — BGP hijacks, volumetric DDoS, and peering fabric failures can cascade into national outages. We design and operate carrier-grade backbones for ISPs across South Asia and the Gulf, including scrubbing centres that have mitigated 400Gbps+ attacks without customer impact.

// The challenge// Our answer
400Gbps+ volumetric DDoS disrupting downstream customers
Anycast scrubbing centre — <5s diversion, zero customer impact
BGP route leaks exposing customer traffic to third-party AS
RPKI origin validation + MANRS-aligned filtering on all peers
Spine-leaf fabric saturating at 10G during peak hours
100G/400G spine-leaf redesign — headroom to 10x current load
5G RAN backhaul designed separately from core — inconsistency
Unified 5G backhaul and core transport design — single NOC view

"We had a 380Gbps attack that would have taken us offline for hours under our previous architecture. Nexora's anycast scrubbing diverted it in under 5 seconds. Our customers never knew it happened. That's the kind of engineering we needed."

06 / 08 — Retail & E-Commerce

Omnichannel networks that keep POS running, card data isolated, and customers connected.

Retail is a patchwork of micro-environments — POS lanes, guest WiFi, inventory IoT, CCTV, digital signage — all on the same physical infrastructure. We design per-function segmentation that achieves PCI compliance without re-architecting the store every audit cycle, then manage it centrally across 100+ sites.

// The challenge// Our answer
POS terminals on same VLAN as guest WiFi — PCI scope explosion
POS micro-segmentation — 74% scope reduction vs flat network
Peak-season bandwidth saturation causing transaction failures
Elastic SD-WAN with burst capacity — QoS-prioritised POS lanes
No central visibility across 100+ store networks
Single-pane management — Meraki Dashboard + SD-WAN controller
CCTV footage stored locally — no forensic-grade retrieval

07 / 08 — Education

Campus networks that scale with enrolment and keep research, student, and staff environments cleanly separated.

Universities face a security challenge unlike any other sector: an open, collaborative culture that must simultaneously protect minors, isolate petabytes of research IP, and keep exam infrastructure tamper-proof — all for a user base that actively tests network boundaries.

// The challenge// Our answer
8,000 student BYOD devices overwhelming WiFi capacity
Wi-Fi 6E campus design — 30:1 client density validated by survey
Research data on same network segment as student BYOD
Research VLAN with dedicated firewall — zero student-to-lab paths
Online exam integrity breached via VPN and proxy circumvention
Exam VLAN with DNS filtering, proxy blocking, and lockdown SSID
No content filtering — CIPA/safeguarding audit failure
DNS-layer filtering with per-SSID policy — CIPA-ready from day one

08 / 08 — Energy & Utilities

SCADA security, substation hardening, and smart-grid telemetry for critical national infrastructure.

Power grids, water treatment plants, and gas pipelines are the highest-value targets for state-sponsored attackers and the least tolerant of downtime. We apply NERC CIP and IEC 62443 controls to industrial control systems that can never go offline for a patch window — using sequenced migration, compensating controls, and live redundancy throughout.

// The challenge// Our answer
SCADA systems reachable from corporate LAN — no perimeter
Substation DMZ with jump server, IEC 61850-aware firewall
Remote substation comms over unencrypted serial links
IEC 61850 GOOSE/MMS encrypted — Smart Grid MPLS backbone

— WHAT CLIENTS SAY

Heard from the people
accountable for the outcome.

These quotes come from CTOs, CISOs, and IT directors who signed off on the work — not marketing team testimonials.

"Two previous integrators delivered PCI infrastructure that failed QSA review. Nexora passed first time. The difference was that they assigned the engineer who would run the audit as the lead architect — they designed to the standard, not around it."

RH
Rashed Hossain
CTO, Apex Commercial Bank
Banking

"Our clinical WiFi now has 99.97% uptime and our radiologists have stopped escalating complaints. More importantly, we passed our HIPAA technical safeguard review without a single finding on network segmentation — the first time in four years."

AK
Dr. Anika Khan
CIO, National Diagnostic Network
Healthcare

"The Purdue model segmentation Nexora built gave us something we hadn't had in 20 years of operations: confidence that an IT breach could not reach our plant floor. When a ransomware attempt hit 6 months later, that confidence was validated — 4 hours to contain, zero production impact."
