Network Risk Management
Understand Your Network to Protect It Better
Business networks connect users, applications, cloud services, endpoints and critical infrastructure. Poorly controlled access, excessive network exposure and limited visibility can make it harder to identify suspicious activity. Petabyte helps organisations review their network architecture and strengthen practical controls based on their environment and business requirements.
Visibility is the foundation of effective network security.
Understand which assets are connected, how traffic flows, which systems are exposed and where access rules or segmentation can be improved.

Frequently Asked Questions
Network Security & Visibility FAQs
What is network security and visibility?
Network security combines controls that protect network access and communications. Visibility refers to the information available about connected assets, traffic flows, network events and potential risks.
Why is network visibility important?
Visibility helps teams understand their environment, investigate unusual activity, identify unexpected connections and make informed decisions about network controls.
What is network segmentation?
Network segmentation divides an environment into controlled zones or boundaries. Appropriate segmentation can limit unnecessary communication and help contain the impact of certain incidents.
Can network security cover cloud and on-premises systems?
Yes. An assessment can consider on-premises infrastructure, cloud networks and connections between environments, depending on the agreed scope and available access.
Does improving network security require replacing existing infrastructure?
Not always. Some improvements may involve configuration changes, rule reviews, better logging or segmentation. The appropriate approach depends on the existing architecture and identified risks.
