The trust-account wire is a six-figure mistake waiting to happen.
Closing day. Real estate. M&A. Litigation settlement. When a fraudulent wire instruction lands in a partner’s inbox and Microsoft Defender approves it, your malpractice carrier learns the term “social-engineering exclusion.” StrongestLayer reasons about every client email, including the perfectly-written one.
The patterns getting past Microsoft Defender and Mimecast.
Each is sophisticated enough to clear a legacy gateway, and each is reasoning-detectable in seconds.
A partner has been emailing the buyer’s CFO for weeks. On closing day, an email arrives with revised wire instructions for the closing — same tone, same signature, different domain. The buyer’s inbox was compromised weeks earlier.
An attacker poses as the client on an active matter, asks a perfectly reasonable question, and angles for a sensitive document. AI-drafted to match prior thread tone. The associate has no reason to second-guess it.
A targeted lure aimed at a specific partner using compromised counterparty thread context. Drops the partner into a credentials page that looks identical to the firm SSO. One credential set unlocks every active matter.
Partners need to know we’re not reading their mail.
Email content is processed in memory and never written to long-term storage. Only metadata is retained.
Data-handling commitments
- Email content processed in memory by reasoning engines, never persisted
- Only metadata retained — verdicts, reasoning traces, sender features
- No content used to train shared models
- Includable in your client information security addendum (ISA)
- Full data-handling documentation available under NDA
ABA Model Rule 1.6(c) and most state bar cybersecurity opinions require “reasonable efforts” to prevent unauthorized access to client information.
StrongestLayer satisfies the email-borne threat protection and incident response components of those duties — with a documentation pack that maps directly to the ABA Cybersecurity Handbook controls.
Quick answers on law firm deployments.
Does StrongestLayer affect attorney-client privilege?
No. Email content is processed in memory by the reasoning engines and never written to long-term storage. We do not read, store, or transmit privileged communications outside the reasoning operation. Only metadata is retained. Most firms include StrongestLayer in their information security addendum (ISA) for client engagements.
How does StrongestLayer fit with ABA Model Rule 1.6(c)?
ABA Model Rule 1.6(c) and most state bar cybersecurity opinions require lawyers to make “reasonable efforts” to prevent unauthorized access to client information. StrongestLayer satisfies the email-borne threat protection and incident response components of those duties, and we provide a documentation pack mapping to the ABA Cybersecurity Handbook controls.
What about IOLTA and trust account wire fraud?
Wire-redirect attacks at closing are one of the highest-loss scenarios for law firms. TRACE flags wire-routing-change patterns even from clean senders, and Inbox Advisor pauses partners before they authorize an out-of-pattern wire.
Will it disrupt how partners actually work?
No. We integrate via API — no MX changes, no parallel-run period. Partners won’t notice it’s there until Inbox Advisor flags something worth a second look.
Stop one wire from becoming a state bar matter.
15-minute API deploy. No MX changes. No partner workflow disruption.
