Threat Hunting & Compromise Assessment

Good hunting is not random log-staring. We build specific, testable hypotheses drawn from real attacker behaviour and test each one against your telemetry. If a hypothesis holds, we pull the thread until we understand the full picture.

Nothing has obviously gone wrong, but you want certainty before an audit, a funding round, or a board question you cannot answer with a shrug. Here the value is a documented, evidence-based verdict: either we find nothing and you can say so with confidence, or we surface something quietly that would otherwise have become a breach in a month.

Something feels wrong. A supplier warned you, an antivirus alert fired and vanished, money moved, or a staff member reported strange behaviour. This is faster and more focused. We confirm or rule out an active intrusion, and if one exists we move straight into containment and full incident response without losing a day to handovers.

Managed and one-off engagements

Some clients want a single deep sweep. Others want recurring managed threat hunting so a fresh set of eyes examines their estate every quarter, tuned to the attacks that actually target their sector. We size the cyber threat hunting service to your risk, not to a fixed product tier.

We start with a short call to understand your environment, what prompted the concern, and where your most valuable data sits. Within hours we are ingesting telemetry and forming the first hunting hypotheses. If there is an obvious active threat, triage compresses into minutes and we escalate at once.

If we confirm an intruder, containment comes before cleanup. We isolate affected hosts, cut attacker access, revoke stolen tokens and sessions, and reset the credentials in play, all while preserving evidence rather than trampling it. Rushing to wipe a machine destroys the very proof you need later.

We remove every persistence mechanism we have mapped, close the entry point, and verify the attacker cannot simply walk back in through a second door they left open. One backdoor is never the whole story, so we keep hunting until the estate is quiet.

We help you return clean systems to service in a sensible order, confirm that monitoring now sees what it previously missed, and watch for any sign the intruder tries to come back.

Finally we turn findings into fixes: detection rules for the techniques we saw, tighter logging where you were blind, and a short list of changes that would have stopped this. The point of a hunt is not just to find the attacker but to make the next one visible on day one.

We reconstruct the timeline from initial access through to the latest activity, so you can see the phishing email, the exposed service, or the reused password that opened the door. Understanding the root cause is the only way to be sure eradication actually holds.

We work to a defensible standard. Findings are backed by hashes, timestamps and preserved artefacts, handled so they remain usable if the matter ever reaches insurers, regulators or a court. If you may need a formal forensic report, tell us at the start and we will collect accordingly.

We write and tune the alerts that would have caught this attacker earlier, so the same technique lights up next time instead of slipping past. Where you lacked the logs to detect it at all, we tell you exactly which sources to turn on.

Most intrusions rely on something avoidable: an exposed remote-access service, a shared local admin password, or a mailbox with no multi-factor authentication. We give you the short list that matters most, ranked by how much risk each item removes. None of it is theoretical: every recommendation traces back to something we actually saw or could have seen in your own telemetry, so your team can prioritise with confidence instead of guessing.

An emergency compromise assessment gets a same-day response and a first read on whether an intrusion is live, often within the first day of telemetry. A full estate hunt typically runs three to ten working days depending on how many endpoints and identities are in scope and how clean your logging is. We give you interim findings as we go rather than making you wait for a final document, because if we confirm an active attacker on day two you need to know on day two.

The triggers repeat. A bank or payment processor flags fraudulent transactions tied to your systems. An employee reports that colleagues received messages they never sent. A backup job suddenly balloons in size because data is being staged. A supplier tells you their network was breached and yours connects to it. Sometimes there is no single event, only a nagging sense that the last penetration test found too much and nobody ever checked whether it was already being abused. Any of these is a good reason to look properly rather than hope.

The cost of waiting

Dwell time works against you. The longer an intruder sits undetected, the more credentials they collect, the deeper their persistence goes, and the harder eradication becomes. Hunting early, while the footprint is small, is far cheaper than recovering from the full breach it would have grown into.
