24/7 incident response · Brooklyn, NYC
Ransomware. Data breach. Compromised accounts. Windows and Apple. When something is actively going wrong, the first hour matters more than the next week.
You are not calling a helpdesk. You are reaching the CISSP-certified specialist who will handle the incident.
If one of these describes your morning, stop reading and call. Everything below can wait until after the phone call.
Your systems are locked? Do not attempt to decrypt anything yourself — call immediately.
A click may have opened a door. Speed of response determines the damage.
Unusual behaviour is often the first visible sign of an active intrusion.
Unauthorised access to email, cloud, or business systems requires immediate containment.
Most NYC IT firms cannot handle Apple forensics. We can.
That uncertainty is the problem. We find the answer fast.
The response
We work out what we are dealing with and how far it reaches. On the first call you will get a straight assessment of what is known so far, what still has to be established, and what to do in the meantime.
We isolate affected systems. Fast containment is the difference between losing one machine and losing your entire network — and we tell you the operational cost before anything goes offline.
We acquire and analyse data from Windows, Mac, iOS and Android devices using documented forensic procedures with full chain of custody — and tell you what we can and cannot determine from the data available.
We restore your systems, close the gaps that were used, and deliver a written report prepared for an insurance claim, your counsel, or a compliance audit.
Arkadian is led by a certified security specialist with a quarter century across corporate networks, government advisory work and live incident response.
Data is acquired using industry-standard forensic procedures with full chain of custody documentation. Findings, method, sources and limitations go in one report — written so your counsel, your insurer or your auditor can follow it without a translator.
We know the local business landscape. When remote response is not enough, we come to you anywhere in the five boroughs — and beyond them when the situation calls for it.
Incident response attracts confident promises. Here is the shape of the real thing.
Whether recovery is possible depends on the variant, your backups and how the incident was handled before we arrived. We will tell you early which of those three is the deciding factor in your case.
We can often establish how access was obtained and what was reached. Attributing it to a named person usually requires records held by providers rather than by you, and sometimes law enforcement.
We document the technical facts, the method behind them and their limits, in the form insurers and counsel expect. How any body evaluates that evidence is their decision, not something we can promise on their behalf.
Containment sometimes means taking something offline, and recovery sometimes means rebuilding rather than restoring. You will hear the trade-off before we act, not after.
Do not email. Do not fill in a form. In an active incident the delay between writing and reading is the part that costs you. Call, and if it turns out the situation is under control, you will hear that too.
Please don't put passwords, account details or incident material in an email. If your mail system is the thing that was compromised, use a different channel entirely.
