Network assessment: common questions
What does a network assessment cover?
Firewalls, switches, VLANs, Wi-Fi, VPNs, internet links, DNS and DHCP, plus how the network is documented and changed. You get a current diagram, findings and a prioritized fix list.
How is this different from the IT infrastructure assessment?
A network assessment covers the network only. The IT infrastructure assessment also covers servers, Active Directory, backups, cloud services and day-to-day IT operations.
Can you assess a mixed-vendor network?
Yes. Most business networks mix vendors. We review how the whole network is configured, connected, documented and maintained.
Is this the same as a security audit?
No. This assessment focuses on how the network is built and run. Formal security audits and compliance readiness are done by our sister company, OC Security Audit.
How much does a network assessment cost?
It depends on the number of locations, network devices and access points in scope. The first 30-minute review is free, and you get a written quote before work starts.
