Background

Headquartered in New York City, the international law firm was founded in 1879. Sullivan & Cromwell consistently ranks as one of the world's top-rated law firms in multiple categories by many organizations such as Bloomberg, The American Lawyer's Global Legal Awards, and America's Best Corporate Law Firms in the 16th annual "Law in the Boardroom" study.

Challenge

The law firm of Sullivan & Cromwell was attacked across all their direct dial-in numbers with robocalls and spoofed calls. The robocalls tied up the law firms voice network resources by leaving voice mails for people from a spoofed law firm phone number. Callers tied up the phone lines to ask why they had received a fraudulent voicemail message from the law firm.

The overwhelming number of robocalls and spoofed calls resulted in the partners wasting significant billable time answering fraudulent calls.

  • Spoofing & Impersonation
  • Robocalls & Voice Spam

Approach

Sullivan & Cromwell asked SecureLogix to white list all legitimate callers to the law firm during the first year of deployment. SecureLogix created the white list with thousands of contacts for all employees, clients, and vendors. All rejected incoming numbers were reviewed by the telecom manager. Instead of blocking fraudulent numbers, SecureLogix blocked all incoming calls and only allowed the approved white numbers to connect to the law firm.

Result

All spoofing attacks have been halted and incoming robocalls are now filtered. SecureLogix protects Cromwell & Sullivan's voice systems and communications from attack, disruption, fraud, and abuse. With SecureLogix managing the security service for the renowned international law firm, Sullivan & Cromwell can focus on its high-profile legal work without missing any important calls.
