Niagara Networks - Network Visibility

The Challenge

“Your security is only as good as your visibility and availability…”

 

As the attack surface continues to expand, the scalability of inline cybersecurity tools and preservation of high availability architectures become a challenge.

NetOps and SecOps  seek to reduce the risk of security attacks and outages. This necessitates implementing a combination of products that can always protect and address threats, as well as enable highly flexible monitoring and high availability capabilities

 
 

Active In-line Security Tools Need High Availability

 

Uptime is critical...

Preventing network failure in case of security tool failure - by using inline bypass switches

Niagara Networks' carrier-grade inline bypass solution  ensures inline security tool efficiency. It makes sure that data packets are not lost, and all the essential data traffic continues to travel smoothly over the network, even when inline security devices need to be replaced, rebooted, or removed due to failure or for maintenance.

Maintaining high availability of the security service (in case of tool failure) by implementing redundancy schemes

NN Bypass HA Active-1

The Niagara Device is used for implementing 1+1, 1:1 and n+1 redundancy between security appliances. 

 

NN Bypass HA Standby-1

The passive bypass allows for continuous traffic flow even if the Niagara device itself fails.

Increasing security solutions’ efficiency

Increase efficiency by setting load balancing schemes to cover all traffic, and maintaining a flow-aware policy.

Load balancing between similar inline devices allows you to utilize existing network security tools (with lower processing performance), to handle higher capacity network links. For example: if your tool supports up to 10G and you want to upgrade your network to 100G, you can load balance your traffic to multiple tools.

Ultimate flexibility and service integrity allows you to take down a security tool for maintenance and the load balancing scheme will automatically redistribute the traffic to the remaining tools.

NN LoadBalance

No single network security tool provides you with all the security you need. You can use Niagara Networks' solution to distribute traffic between different types of security solutions, sending the right traffic to each tool, optimizing traffic management, and tool utilization.
