Incident response & cyber preparedness — IT · OT · IoT

Be prepared.
Stay resilient.
Respond with confidence.

When an incident strikes we go past the visible threat and unravel the entire chain — how they got in, what they touched, and what would let them back. Containment is not the finish line.

4 hours

Assured response time from first contact, 24/7.

+100k

Hours in research and DFIR expertise.

~85%

MTTR reduction may be achieved with our IR team.

Anatomy of an incident

Every breach has three acts. Most companies only ever see the second.

The night of the incident is the part everybody remembers. The work that decides how it ends happens on either side of it.

IMonths before

Act one

The gap that nobody knows is there.

A log source that was never enabled. An OT segment the EDR does not reach. An escalation path routed to someone who left last year. None of it announces itself, and all of it surfaces at the worst possible hour.

Cyber Preparedness — find it on a quiet Tuesday, for a fraction of the cost.

IIThe night of

Act two

Four hours that decide the next four months.

First contact starts the clock. Remote memory capture begins immediately, because the evidence that answers the hardest questions is the evidence that disappears first. Containment is planned against the actor, not the alert.

Emergency IR — assured four-hour response, 24/7, remote acquisition from minute one.

IIIThe months after

Act three

Whether it happens again.

Most incidents are closed at the symptom and recur a month later. We stay through eradication, verify the access path is genuinely shut, and feed what we learned back into your detections.

T3aaS — senior escalation and continuous hunting, so the same class of alert closes itself next time.

New — agentic incident response

A.T.H.E.N.A

Automated Threat Hunting & Evidence Neutralization Architecture

Nine specialist agents work your case in parallel from the moment it opens — triage, memory forensics, reverse engineering, hunting, timeline and intel, all at once. Every action that would change your environment still waits for a named responder. The agents do the hours; our people make the calls.

See it live

The agent fleet — nine specialists, nine models

  • OrchestratorDecomposes cases and routes to specialists
  • Triage SpecialistRapid assessment and IOC extraction
  • Memory ForensicsMemory deep-dive and rootkit hunting
  • Malware REDecompilation and capability extraction
  • Threat HunterHypothesis-driven hunting and rule sweeps
  • Log & TimelineSuper timelines and log correlation
  • Threat IntelEnrichment and malware family ID
  • Report WriterForensically sound reports with ATT&CK mapping
  • QA ReviewerIndependent verification, always a different model

No agent contains, isolates or deletes anything without a named responder approving it first.

What it changes

9 models

One per agent. Model diversity eliminates systemic blind spots.

Parallel

Nine workstreams advance at once instead of queueing behind one analyst.

SHA-256

Chain of custody on every artefact, with read-only evidence enforcement.

0

Actions taken on your environment without a named human approving them.

What we do

Three engagements. One continuous line from readiness to recovery.

Most organizations discover the gaps in their readiness during an incident, when the cost of finding them is highest. We front-load that work — and we are still there at 3am when it matters.

01

Readiness engagement

Cyber Preparedness

Most organizations discover the gaps in their readiness during an incident, when the cost of finding them is highest. Cyber Preparedness front-loads that work: we map what you actually have across IT, OT and IoT, establish the visibility and access an investigation depends on, and rehearse the response until it is routine rather than improvised.

More on this → Cyber Preparedness
  • Asset and network visibility mapping across IT, OT and IoT
  • Security maturity assessment against your threat model
  • Incident response plan and playbook development
  • Pre-authorized access and tooling, ready before an incident
  • Tabletop exercises and live simulations for your team

02

Ongoing retainer

T3aaS — Tier 3 as a Service

Tier 1 and Tier 2 handle volume; the hard cases escalate. T3aaS gives you that senior escalation tier on demand — the reverse engineers, threat hunters and forensic analysts who resolve the alerts nobody else can close — without carrying the headcount full time.

More on this → T3aaS — Tier 3 as a Service
  • On-demand Tier 3 escalation for your SOC or MSSP
  • Continuous threat hunting across your estate
  • Malware analysis and reverse engineering
  • Compromise risk assessment
  • Detection engineering and tuning

03

24/7 emergency response

Emergency Incident Response

Neutralizing what you can see is not containment. Our incident response engagements run the full chain — detect, contain, eradicate, recover — and do not close until we understand how the actor got in, what they touched, and what would let them back. Assured response within four hours of first contact.

More on this → Emergency Incident Response
  • 24/7 emergency intake, four-hour assured response
  • Remote volatile-memory capture and forensic acquisition
  • Full attack-chain reconstruction and root cause analysis
  • Containment, eradication and guided recovery
  • Post-incident reporting and hardening recommendations

How it works

Commanding cyber maturity to eliminate uncertainty.

Step 01

Be Ready

Reduce MTTR

Clear visibility, comprehensive system details, pinpointed vulnerabilities, and ready-to-act permissions for instant response.

Step 02

Get Set

Proactive measures, effective controls and functionality — plus exercises and simulations that let your team handle incidents confidently when they arise.

Step 03

Fast Response

Time to act

Detect, contain and recover. We analyze every angle, eliminate the immediate threat, and meticulously unravel the entire attack chain.
