Cybersecurity & Resilience
Defensive engineering for organisations that require empirical proof of security posture. We build, test, harden, and validate security controls at the operating system, network, and application layers.
Defensive Engineering Scope
Our hands-on security engagements focus on measurable reduction of blast radius and vulnerability surface.
Security Architecture
Rigorous perimeter decomposition, segmented network topologies, encrypted transit enforcement, and least-privilege identity federation.
- • Network micro-segmentation
- • Blast radius containment
- • Cryptographic interconnects
Detection Engineering
Authoring high-fidelity detection rules (Sigma, Wazuh, Suricata, YARA) tuned against specific threat actor TTPs, eliminating false-positive noise.
- • Wazuh custom decoder development
- • MITRE ATT&CK coverage mapping
- • Log pipeline deduplication
Security Hardening
Linux kernel sysctl tuning, disabling unnecessary attack surfaces, SSH key hygiene, read-only filesystem containers, and automated CIS compliance scripts.
- • CIS Linux Benchmark enforcement
- • Container runtime isolation
- • Disabling unneeded kernel modules
Zero-Trust Readiness
Transitioning infrastructure from static IP/VPN perimeters to context-aware, mutual TLS, and cryptographically verified device authentication (e.g. Tailscale/WireGuard meshes).
- • Hardware token (FIDO2) integration
- • Software-defined perimeter design
- • Continuous identity validation
Incident-Response Readiness
Pre-instrumenting forensic capture points, immutable log vaults, isolated quarantine VLANs, and automated containment webhooks.
- • WORM storage for security logs
- • Live memory capture readiness
- • Containment trigger validation
Security Automation
Building automated threat enrichment workflows via MISP and n8n, automated credential rotation upon anomaly detection, and CI/CD vulnerability gates.
- • MISP IoC feeds integration
- • n8n security playbooks
- • Automated IP reputation tagging
