Rate: £450 – £550 Inside IR35

Role Overview: We are on the hunt for a skilled Firewall Engineer with extensive experience in Fortinet firewalls and FortiManager policies.

What You’ll Do:

Your Expertise:

• Proficient in using Splunk queries (desirable).

Background: Our current firewall rules in RDCs and HQ are too permissive and need stricter controls. Information about required ports for servers and applications is currently lacking, but a comprehensive list of firewall rules from an existing template can be used as a baseline.

Goal: To review, create, and tidy up all firewall rules in warehouses and HQ.

Concept welcomes all applications. Right to Work is a requirement as no sponsorship is offered for this role.
