Firewall & Network Defence
Design, harden and tune network defences so only the traffic you intend gets through.
We design and harden network defences: next-generation firewalls, segmentation, intrusion prevention and secure remote access, built around a least-privilege model. We review existing rule bases to remove risky, redundant and overly permissive rules, and align segmentation with zero trust principles so a single foothold cannot reach everything. Configurations are documented so your team can maintain them with confidence.

Rule base review
Cleanup of risky, redundant and overly permissive rules with documented rationale.
Secure remote access
Hardened VPN and zero trust access so remote users connect safely.
What you walk away with

A clear path from problem to outcome
Scope and rules of engagement
We agree targets, objectives and constraints in writing: in-scope assets, test windows, success criteria and emergency stop conditions. You get a signed authorisation and a named point of contact before any tooling touches your environment.
Execute and validate
Our team runs the engagement against agreed objectives, whether that is exploitation, detection validation or a build. Activity is mapped to MITRE ATT&CK where relevant, and we confirm each finding so you receive evidence, not noise.
Report with reproducible proof
Every finding ships with a reproducible proof of concept: request and response, payloads, screenshots and exact steps. Risk is rated by business impact and likelihood, with clear, prioritised remediation guidance your engineers can act on.
Remediate and retest
We walk your team through fixes, answer questions and retest to confirm closure. You finish with a clean retest record and, where useful, detections and runbooks so the same gap is caught next time.
