Network Infrastructure Security
Secure the foundation that every other system depends on.
Overview
Routers, switches and the cabling logic between them are the foundation of your network. Hardening that layer protects everything running on top of it.
Infrastructure devices are often deployed once and rarely revisited. Default credentials, unnecessary services and flat network designs leave a quiet attack surface that is easy to overlook.
NexLink reviews and secures the core of your network: routers, switches, segmentation and access management, so that connectivity is both reliable and deliberately controlled.

Business benefits
What your business gains.
Reduced attack surface
Unneeded services and weak defaults are removed or restricted.
Contained incidents
Segmentation limits how far a problem on one device can spread.
Controlled access
Management access to infrastructure is restricted to who needs it.
Predictable design
A documented architecture is easier to maintain and expand.
Typical project workflow
How a project usually runs.
- 1
Inventory
Infrastructure devices and their roles are identified and documented.
- 2
Design review
Current topology is compared against a more secure target architecture.
- 3
Hardening
Device configurations and segmentation are implemented in planned stages.
- 4
Verification
Connectivity and access are tested, and the final configuration is documented.
Suitable applications
Where this service fits.
- Offices running a single flat network
- Businesses adding VoIP, cameras or IoT devices

FAQ
Frequently asked questions.
What is network segmentation?
It is dividing a network into separate zones, for example staff, guests and servers, so that traffic between them can be controlled.
Will hardening break existing connections?
Changes are planned and staged, and tested with you, to minimize unexpected disruption.
Do you support multiple vendors?
We evaluate your specific equipment during scoping and confirm what we can support before work begins.
