For open source firewalls; this technology delivers state-of-the-art, next-generation features not currently available in products such as OPNsense. If you are running an L4 firewall (all open source firewalls fall into this category) and need features such as Application Control, Network Analytics, and TLS Inspection, Zenarmor provides these features and more.

Technology​

The product's underlying technology is a lightweight yet powerful packet inspection core that can perform a wide range of enterprise-grade network security operations.

Unique Appliance-free Technology​

Lightweight and powerful appliance-free technology enables enterprises to instantly install instant firewalls and easily safeguard environments as small as home networks or as large as multi-cloud deployments. It's as simple as launching an application.

The packet inspection core is robust enough to guard against encrypted threats while remaining lightweight and agile enough to work in resource-constrained environments.

Zero-latency Security Stack​

Deploy zero-latency security without backhauling data packets back and forth between POPs and data centers.

Zenarmor’s single-pass architecture processes packets once and for all security controls.

The same security stack runs wherever deployed for an unprecedented level of consistency when applying security policies.

Deploy Anywhere, Rule from the Cloud​

Inspect locally, analyze and manage centrally.

Cloud-based management provides a control for all policies and network deployments.

Design policies independent of locations and devices and enforce them across all IT environments.

All security telemetry can be aggregated and seen through a single pane of glass. Begin with an enterprise-level view and drill down to individual connection details.
