Cyber Insurance Coverage Lawyers

You bought the policy for exactly this. Then the claim was denied, delayed or paid at a fraction of the loss.

We read the policy against the facts, build the proof of loss and, when the insurer will not move, litigate or arbitrate. Insurers retain us for the same analysis from their side.

Why It Matters

Most denials turn on how the loss is described, not whether it happened.

Cyber, crime and funds-transfer-fraud coverages insure different events. The same wire can be covered under one and excluded under another.

Insurers also look backward. If the application said multifactor authentication was in place and it was not, the policy itself may be challenged.

The answer is evidence. A privileged forensic record of what happened, matched to the policy language, is what moves a claim.

The Landscape

The losses are large, and the policy language is specific.

Government data on the frauds that drive most cyber and crime claims, and the New York rules that shape them.

Business email compromise losses reported to the FBI in 2025

§ 3105
New York Insurance Law section under which a material misrepresentation in the application can void the policy

New York also requires businesses holding private information to maintain reasonable safeguards. Insurers increasingly ask whether those safeguards existed when the loss occurred. Sources: FBI Internet Crime Complaint Center, 2025 Internet Crime Report; N.Y. Insurance Law § 3105.

What We Do

From notice to award.

Policyholders

Policy review before and after a loss

Which coverages respond, what the sub-limits are and what conditions must be met. Before renewal, and the day a loss occurs.

Policyholders

Notice and proof of loss

Notice in the form the policy requires. A proof of loss built on forensic findings, not on the insurer’s framing.

Policyholders

Denied and underpaid claims

Rebuttal of exclusions, causation arguments and valuation disputes. Litigation or arbitration when the insurer will not move.

Policyholders

Rescission defense

Response when an insurer alleges the application misstated security controls. The record of what actually existed matters.

Insurers

Coverage and causation evaluation

Independent analysis of how the loss occurred and which provisions apply. Forensic review included.

Both

Subrogation and third-party recovery

Claims against the carrier, vendor or bank whose failure caused the covered loss.

How We Work

How a coverage dispute is built.

The facts come first. The policy is read against them, not the other way around.

01

Policy and application review

Every coverage part, endorsement, exclusion and the answers given at application.

02

Forensic record

How the loss happened, documented under privilege. This is the evidence the claim stands on.

03

Notice and proof of loss

Timely notice in the required form. A proof of loss that anticipates the insurer’s objections.

04

Negotiation

Response to reservation-of-rights and denial letters with the record attached.

05

Litigation or arbitration

Filed where the policy and the facts allow. Expert and forensic testimony ready.

The Team Behind the Case

Investigators and lawyers, under one roof.

The investigative team

Retired federal law enforcement.

Former federal investigators and analysts who spent their careers on cyber and financial crime. They handle the forensics, the tracing and the contact with current law enforcement.

The legal team

Arbitrating cybercrime disputes since 2019.

Counsel in more than 130 arbitrations before AAA, JAMS and NAM, most arising from cybercrime and account takeovers. We try these cases on the evidence.

If It Is Happening Now

Notice first. Statements later.

Policies impose conditions from the moment of discovery. Missing one can cost the claim.

Do
  • Read the notice provision today; the clock may already be running
  • Give notice in the form the policy requires, after counsel reviews it
  • Preserve the forensic evidence of how the loss occurred
  • Keep every invoice and record of response costs
  • Request the complete policy, including all endorsements
Do not
  • Give a recorded statement about causation before the facts are established
  • Pay a ransom or approve a vendor without checking consent requirements
  • Accept the insurer’s characterization of the event
  • Let the forensic vendor report to the insurer alone
  • Assume a denial letter is the final word

FAQ

Frequently asked.

Rarely. Denials often rest on how the insurer characterized the event. A forensic record and the right coverage part can change the result.

Policies also contain appeal and dispute provisions. We use them.

Cyber policies respond to breaches, extortion and business interruption. Crime policies respond to theft, including fraudulent transfers.

A misdirected wire may fall under either, or under a funds-transfer-fraud endorsement with its own sub-limit.

Under New York law a material misrepresentation can void the policy. The question is what was true when the application was signed.

We reconstruct the controls that existed and challenge the materiality claim.

It depends on the policy. Some require notice within days of discovery. Read the provision now, and give notice after counsel reviews the wording.

Yes. Insurers retain us to evaluate coverage and causation, including forensic review of how the loss occurred.

Sometimes. Where a third party’s failure caused the loss, a claim against it may sit alongside or in place of the insurance claim.
