Apex Bank's legacy flat network was failing PCI QSA reviews for the third consecutive year and couldn't sustain the failover SLA demanded by their new core banking platform. Nexora designed and delivered a full stack replacement — active-active data centres, SD-WAN across 84 branches, NGFW with microsegmentation, CrowdStrike EDR, and a 24/7 SOC integration — without a single hour of unplanned downtime during the 11-month cutover.
"Nexora passed our PCI QSA review on first attempt — after two previous integrators couldn't. The difference was they designed to the standard rather than around it."
Full-stack replacement — active-active DC, SD-WAN, NGFW microsegmentation, EDR, and 24/7 SOC — without a single hour of unplanned downtime during the 11-month programme.
Purdue model OT/IT segmentation, IIoT mesh deployment, and OT-aware firewalling across six manufacturing plants — including live cutover with no production downtime.
Clinical WiFi 6E design, medical device NAC isolation, ePHI segmentation, and ransomware-resistant backup — first HIPAA technical safeguard pass in four years.
100G/400G spine-leaf rebuild, anycast scrubbing centre commissioning, RPKI/MANRS routing hygiene — first 380Gbps attack absorbed without a single customer complaint.
Full air-gap design, multi-level security classification, sovereign cloud architecture, and DLP enforcement — two independent security audits returned zero findings.
Multi-site SD-WAN, POS micro-segmentation, centralised VMS CCTV with AI analytics — PCI audit findings dropped from 40+ to 4 in a single cycle.
IEC 61850-aware communications, substation DMZ design, smart grid MPLS backbone, and SCADA security — full NERC CIP compliance achieved without a single substation going dark.
Juniper Mist Wi-Fi 6E, ClearPass NAC, per-SSID DNS filtering, and research VLAN isolation — supporting 8,251 concurrent devices with a 4× capacity increase from the legacy system.
AWS/Azure multi-cloud landing zone, IaC pipeline, CSPM implementation, and FinOps programme — 27% cloud cost reduction in year one with zero regulatory compliance gaps.
Apex had already tried twice with other integrators. Both attempts stalled in the design phase when the scope of cutover risk became clear. Nexora assigned a primary architect and a dedicated cutover engineer, designed the phased migration with per-branch rollback runbooks, and executed the 84-site cutover over 11 months with a 100% on-time branch record.
"We had tried twice before. Nexora was the only team that came in with a phased cutover plan that the board actually understood — and then executed it exactly as written. First PCI QSA pass in four years."
Bashundhara's factories were running on completely flat networks — a corporate engineer's laptop could reach a PLC directly. When a phishing email hit a factory manager's machine in 2023, Nexora was called in post-incident. The re-architecture was completed in 8 months with a sequenced cutover plan that kept all six production lines running throughout.
"A ransomware attempt hit us 6 months after go-live. Because Nexora had segmented our OT environment and written the runbook, our team contained it in under 4 hours — without stopping a single production line. That ROI calculation is easy."
NDN had failed their HIPAA technical safeguard assessment for four consecutive years due to flat network topology — imaging servers, patient WiFi, and staff machines were all on the same VLAN. The redesign required Ekahau-validated RF planning across 14 different hospital floor plans, live cutover without interrupting ICU or theatre WiFi, and immutable backup architecture resistant to the healthcare-targeted ransomware campaigns active in the region.
"Our radiologists finally stopped escalating WiFi complaints. And for the first time in four years, we passed our HIPAA technical safeguard review without a single finding on network segmentation. That's what purpose-built clinical infrastructure looks like."
