## Our take

What our shortlists say about the one we picked.

### [Versa Next Generation Firewall](https://cybersectools.com/tools/versa-next-generation-firewall)

Best for: Enterprises needing deep IoT and OT device visibility alongside NGFW

The deployment flexibility is real: cloud, virtual, and on-premises with a unified management console and zero-touch provisioning. The ZTNA capability is on-premises, which is less common than cloud-delivered ZTNA and suits organizations that need ZTNA without routing traffic through a vendor's cloud. The integration surface is broad, covering IAM, SIEM, SOAR, DLP engines, and encryption engines through native and API connections. The trade-off is that Versa is less well-known than Palo Alto, Fortinet, or Cisco, which means smaller community resources and potentially longer vendor support response times.
