Regulated environments don't tolerate generic IT. For 15 years we've embedded in banking floors, clinical networks, factory OT environments, and government data centres — building infrastructure that passes audits and survives incidents.
Each sector block below covers the specific challenge set, Nexora's approach, real outcome metrics, and a client case study snippet.
PCI-DSS environments, core banking continuity, SWIFT CSP compliance, and real-time fraud monitoring infrastructure.
HIPAA-compliant networks, clinical WiFi, medical device isolation, and ransomware-resistant backup for hospitals and diagnostic chains.
OT/IT convergence using the Purdue model, IIoT sensor fabrics, SCADA security, and plant-floor cybersecurity without production downtime.
Air-gapped networks, sovereign data residency, multi-level security classification, APT threat hunting, and SBOM supply chain assurance.
Carrier-grade spine-leaf fabrics at 400G, anycast DDoS scrubbing, RPKI/MANRS routing hygiene, and 5G RAN backhaul design.
POS micro-segmentation, guest WiFi isolation, SD-WAN for 100+ stores, AI video analytics, and P2PE-ready network architecture.
Wi-Fi 6E campus deployments, BYOD NAC, research VLAN isolation, SSO identity management, and DNS content filtering for CIPA compliance.
NERC CIP controls, IEC 61850-aware communications, substation DMZ design, smart grid MPLS, and SCADA security for critical national infrastructure.
We have delivered core banking environments for commercial banks, investment firms, microfinance institutions, and payment processors across Bangladesh, Singapore, and the Gulf — each under active QSA or regulatory review. Zero incidents on record.
"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."
"Before Nexora, our imaging servers and guest WiFi were on the same VLAN. After the redesign, we passed our HIPAA technical safeguard review for the first time in four years — and our radiologists stopped complaining about DICOM latency."
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.
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.
"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."
"The air-gapped network Nexora designed for our classified division has undergone two independent security audits since commissioning — both returned zero findings. The sovereign cloud architecture means we have never had data leave national jurisdiction."
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.
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.
"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."
"Our PCI audit used to take three months and result in 40+ findings. After Nexora redesigned our store networks with proper POS segmentation, our last audit took two weeks and returned four minor observations — none related to network architecture."
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.
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.
"Our previous WiFi couldn't handle more than 2,000 concurrent students. Nexora's Wi-Fi 6E design handles 8,000+ with headroom to spare. Our researchers can work without competing for bandwidth with students watching YouTube — they're finally on separate infrastructure."
"Nexora were the first integrator who understood the difference between securing IT and securing OT. They applied NERC CIP controls without demanding we take substations offline — the cutover was sequenced so that not a single substation lost communications during the migration."
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.
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."
"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."
"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."
