Emergency incident response team

Under attack? Call now.

Ransomware on the server. A hijacked mailbox. A wire that went to the wrong account. Our incident response team gets to work the moment you call, whether or not you are a Cytek client today.

Cytek analysts have handled ransomware, business email compromise and data theft for medical practices, manufacturers, law firms and financial institutions. We contain the attack, get you back to work, and manage the reporting clocks that start the moment a breach is discovered.

Why speed matters

The first hour: what to do, and what not to do

  1. Call us. (844) 644-8744. Tell us what you are seeing. We will walk you through the next steps on the phone.
  2. Disconnect, do not power off. Unplug network cables or turn off Wi-Fi on affected machines. Leave them running so evidence in memory is not lost.
  3. Do not reply to the attackers or pay anything. Save the ransom note or email and forward nothing yet.
  4. Change nothing else. No wiping, reinstalling or restoring from backups until we know how they got in, or they come straight back.
  5. Gather the basics. Who noticed what and when, which systems are affected, who has admin access, and your cyber insurance policy number.
  6. Notify your cyber insurer. Most policies have a notice deadline. We work within your carrier’s requirements.

What our team does

Contain

Isolate affected systems, cut the attacker’s access, reset credentials and block the paths they used, so the damage stops growing.

Investigate

Find how they got in, what they touched and what left the building, with evidence preserved for your insurer, attorney and regulators.

Recover

Rebuild or restore clean systems in the right order, verify them, and get people working again without reopening the door.

Report and harden

Meet every notification deadline (HIPAA, Oklahoma, banking, SEC, FTC), brief your leadership in plain language, and close the gaps that let it happen.

Why companies call Cytek

  • Analysts, not a call center. The person who answers is the person who works your incident, from a team based in Tulsa.
  • We know the deadlines. HIPAA, the Oklahoma breach law, bank and credit union rules, SEC and FTC notices. We have filed them before.
  • We talk to everyone. Your insurer, your attorney, your IT provider and your board, in language each of them understands.
  • We stay after. Most incident response firms leave when the fire is out. Our 24/7 monitoring and Microsoft 365 protection make sure the same attacker does not walk back in.

FAQ

Frequently asked questions

Do we have to be a Cytek client to call?

No. Call (844) 644-8744 and we will triage the situation with you. We give you a clear scope and quote before any work beyond the initial triage begins.

Should we pay the ransom?

The FBI advises against paying, and payment does not guarantee you get your data back or that it was not already copied. The decision is yours, made with your attorney and insurer. We help you understand what you actually lost and whether recovery without paying is realistic.

Who do we have to notify, and how fast?

It depends on your industry and where your customers live. Examples: HIPAA covered entities have 60 days to notify affected patients and HHS; Oklahoma requires notice to the Attorney General within 60 days when 500 or more residents are affected; banks have 36 hours to tell their federal regulator; credit unions have 72 hours to tell the NCUA; businesses under the FTC Safeguards Rule have 30 days. We keep the list for you and prepare the notices.

Should we shut everything down?

Disconnect affected machines from the network, but leave them powered on. Shutting down destroys evidence in memory that tells us how the attacker got in. Call us before doing anything else.

What happens after the incident is over?

You get a written report in plain language for your leadership, insurer and attorney, a list of the gaps that were used, and a plan to close them. Most clients move onto 24/7 monitoring so the same thing cannot happen twice.
