Manageable
Remove complexity by simplifying creation and enforcement of policies.
Closing the operational technology (OT) security gap
At the heart of cyberattacks, network insecurity and specifically TCP/IP are central to virtually every cybercrime. Why?
The traditional air gap disappears when sensors and devices are connected using TCP/IP on hybrid networks. This is where OpenBlue Airwall comes in.
Using a transformative technology that protects any type of connected device from cyberattacks, OpenBlue Airwall protects critical infrastructure with the industry's only identity-based, zero trust platform.
OpenBlue Airwall enables
Protect critical infrastructure from discovery & attack.
Manage employees, vendors, third parties.
Secure data transport from critical infrastructure to cloud and back.
OpenBlue Airwall benefits
- A complete zero trust portfolio.
- Securely connect anything, anywhere over any network.
- Private overlay networks on top of existing infrastructure, no need to rip and replace.
- Easy to manage identity-driven policies.
- Micro-segmentation with end-to-end encryption.
- Reduces attack surface by 95% while reducing cost and complexity by 50-80%.
How does it work?
- Creates private overlay networks based on encrypted tunnels and trusted cryptographic identities to secure network traffic.
- OpenBlue Airwall provides total control over communications.
- Single pane of glass management console provides simple, scalable, and extensible policy management between things.
- Based on Host Identity Protocol (HIP), an open IETF standard developed to fix the lack of mobility and security flaws of TCP/IP.
