Your SIEM and EDR are only as good as the rules inside them. We build, tune, and maintain high-fidelity detections that catch real attacker behaviour — and cut through the noise that drowns your analysts every day.
Most organisations accumulate detection rules over time without a coherent strategy — resulting in mountains of noisy alerts, significant coverage gaps, and analysts who have lost trust in their tooling. Detection Engineering brings rigour and intentionality to how you detect threats.
We work from your threat model outward, building use cases that reflect the adversary techniques most likely to target your environment. Every rule is documented, tested, and mapped to MITRE ATT&CK. Existing detections are systematically tuned to eliminate false positives and restore analyst confidence. The outcome is a lean, high-signal detection library that your team can actually act on.
Custom SIEM and EDR rules built to detect real attacker TTPs in your specific environment.
Systematic review and tuning of existing detections to reduce noise and improve alert fidelity.
Mapping your current detections against MITRE ATT&CK to identify blind spots and prioritise new use cases.
Every detection is documented with context, logic, and triage guidance so analysts know what to do when it fires.
We start with who is likely to attack you and why — then build detections that reflect those specific adversary behaviours, ensuring your resources are focused where they matter most.
We write detections in SIGMA — the vendor-neutral detection format — so your rules are portable, maintainable, and not locked to a single platform. Compile to Splunk, Elastic, Microsoft Sentinel, and more.
We deliver a visual heatmap of your detection coverage across MITRE ATT&CK, giving leadership and analysts a clear picture of where you are strong and where investment is needed.
Analysts overwhelmed by noisy, low-fidelity alerts who need a detection library they can trust and act on efficiently.
Organisations moving to a new SIEM platform who want to migrate and improve their detection library rather than simply copy it over.
After an incident, close the detection gaps that allowed the attack to go unnoticed and ensure the same technique is caught the next time.
