Juniper unveiled what it’s calling its Software-Defined Secure Networks (SDSN) at its Nxtwork 2016 event this week. Much of it seems comprised of existing products the company has bundled together under the SDSN moniker. But there is some new security software called Policy Enforcer that can prevent threats all the way down to access switches.

The Policy Enforcer automates security policies across the network and quarantines infected endpoints by invoking the Junos Space Security Director (another existing product).

The company also introduced the SRX4000, a new mid-range series of firewalls for hybrid cloud and enterprise campus environments.

Juniper has been assembling security products as part of SDSN over the last 15 months. The products include its container-based SRX (cSRX), its virtual SRX (vSRX), its Sky Advanced Threat Protection for campus, and the SRX300 for branch offices.

As of yesterday, its Sky Advanced Threat Prevention extends malware protection across both virtual and physical firewalls.

“SDSN is the future of security,” said Jonathan Davidson, EVP and GM of Juniper’s development and innovation group, at the Nxtwork event. The company is moving from hardware-based security at the perimeter to software security that permeates the network.

Pretty much every network security vendor is making this same transition as fast as they can.

“Unique in the industry from Juniper is that SDSN stops threats networkwide, with cloud-based anti-malware and with an open policy engine,” said Davidson.
