SERVICE CAPABILITIES
What Network & Infrastructure Security covers
Design and review network security controls including firewall policy, VPN access, zone segmentation, and restricted paths between users, servers, and services.
Design & assessment
Firewall review
Review rules, exceptions, and unnecessary access.

FAQ
Frequently asked questions about Network & Infrastructure Security
Does installing a firewall guarantee security?
No. Policy, configuration, updates, monitoring, and response processes also matter.
Should all VPN users have the same access?
Access should follow role, source, and required service.
Will all old rules be removed?
No. Ownership and impact are reviewed before any approved change.
Is this a penetration test?
No. It covers infrastructure control review and configuration, not an independent penetration test.
