Firewall & Perimeter Security
Review and implement firewall policy across host, network and application layers. We map required traffic, remove unnecessary exposure and plan changes with recovery access available. Rules are documented with purpose and ownership, then validated using expected allowed and blocked flows.
Scope and deliverables
- pfSense, Sophos and host firewall configuration
- UFW, iptables and security-group reviews
- Rule cleanup, NAT and segmentation
- Configuration backups and change validation
Assessment and delivery
We begin with your current environment, access boundaries, application dependencies and business priorities. The scope identifies the systems involved, agreed acceptance checks and the people responsible for implementation and ongoing operation.
Changes are staged where practical. We document configuration decisions, validate representative workflows and plan recovery access before a cutover or restrictive change.
Operational handover
Delivery includes configuration records, essential operating instructions and a review of remaining dependencies. Support windows, response expectations and follow-up work are agreed for the engagement.
