01 · Assess and design
Current OT assets, network topology, and endpoint estates are discovered, then architecture and policy are designed for network access control, cloud firewalls, or SD-WAN as needed.
Network Security
OT/IoT, NAC, Cloud NGFW & SD-WAN
Security for the network layers most organizations build last, operational technology, network access control, cloud-native firewalls, and the SD-WAN fabric connecting it all.
- 4 domains OT/IoT, network access control, cloud NGFW and SD-WAN, covered under one practice
- Phased enforcement Rollout moves from monitor mode to closed-loop enforcement, not all at once
- IEC 62443 OT security aligned to recognized industrial control system standards
The challenge
IoT and operational technology devices now face roughly eight hundred twenty thousand automated attack attempts a day globally, a number that keeps climbing year over year, while ransomware remains the most pervasive threat to critical infrastructure. These are the network layers that were often connected last and secured even later.
Approach
How the engagement works
02 · Deploy in phases
Enforcement moves from monitor mode through low-impact rules to closed-loop enforcement, so legitimate operations are not disrupted along the way during phased implementation, and rollout across production environments.
03 · Operate and optimize
Platforms are operated 24x7 where applicable, with policy tuning, health monitoring, and quarterly review across every domain in scope, including SLA reporting, governance oversight, continuous optimization, executive reporting, capacity planning, and lifecycle management.
How it works
From under-secured network layers to one operating model
What’s included
- OT asset discovery, continuous asset visibility, passive monitoring and IEC 62443 readiness assessment.
- Identity-aware network access control across wired, wireless and VPN
- Cloud-native firewall deployment with hub-spoke or transit architecture
- Secure SD-WAN overlay with integrated edge security
- Phased enforcement from monitor mode to closed-loop
- 24x7 operation, policy tuning and quarterly review across every domain
Outcomes
- Improved operational resilience by reducing cyber risk across converged OT and IT environments.
- Network access controlled by identity, not just by physical port
- Cloud firewall and SD-WAN policy operated continuously, not left static after deployment
Why Gruve
These network layers usually get
connected first and secured last
Operational technology, network access control, cloud firewalls, and SD-WAN often grow organically, connected for convenience long before anyone designs security around them. Gruve adopts a phased implementation approach that enhances security while minimizing operational disruption across OT, IoT and enterprise environments.
