One fraudulent wire from a trust account is a career event.

Partners are the highest-value targets in your firm. Their inboxes contain every active matter. Their wire authority is real. Their reputational exposure is total. StrongestLayer reasons about every client email without getting in the way of how partners actually work.

Built for the Three Sub-Verticals

Different firms. Same threat shape.

High-trust inbound. Partner inbox concentration. Fund-control authority. The threat model is the same; the specific scenarios differ.

Law Firms
Trust accounts, IOLTA, deal closings

A single fraudulent wire from a trust account triggers state bar reporting, malpractice exposure, and client loss. Real estate, M&A, and litigation closings are the highest-risk moments.

  • Closing-day wire-redirect detection
  • Client-impersonation pattern coverage
  • Partner-targeted spear-phishing baseline
  • ABA Cybersecurity Handbook documentation pack
Accounting Firms
Tax season, client data, e-file fraud

Tax season is open hunting. Clients send sensitive data; attackers impersonate the firm or the client to redirect refunds or steal credentials. The damage is regulatory, not just financial.

  • Client-impersonation during tax filings
  • IRS / e-file refund-redirect detection
  • Sensitive-data exfiltration via outbound rules
  • SOC 2, GLBA documentation pack
Consulting & M&A
Deal-flow email, partner concentration

M&A and management consulting partners email with a small number of high-stakes counterparties. One compromised thread reveals an active deal. Targeted attacks are common pre-close.

  • Counterparty-impersonation in active deal threads
  • Partner inbox concentration risk reduction
  • Pre-close wire-redirect monitoring
  • NDA-friendly data-handling commitments
Privilege & Privacy

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 — and we provide a documentation pack that maps directly to the ABA Cybersecurity Handbook controls.

“Email security today is mostly a giant pile of rules and signatures — very brittle, very reactive. StrongestLayer approached it cleanly — LLMs first, architecture built around them. It solves problems the legacy stack literally can’t.”

FAQ

Quick answers on professional services deployments.

Why are professional services firms a top target?

Firms control client funds — trust accounts, IOLTA accounts, escrow accounts — that can be drained with a single fraudulent wire. Partners email about deals and matters constantly with high-trust counterparties an attacker can impersonate. Partner email accounts are uniquely attractive: a compromised partner inbox provides intelligence on every active matter.

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 — verdicts, reasoning traces, sender features — is retained. Most firms include StrongestLayer in their information security addendum (ISA) for client engagements.

How does StrongestLayer fit with the ABA Model Rules?

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 that maps directly to the ABA Cybersecurity Handbook controls.

Will StrongestLayer disrupt client communications or partner workflows?

No. We integrate via API with Microsoft 365 or Google Workspace — no MX changes, no mail-flow disruption. Partners and associates won’t notice the platform is there until Inbox Advisor explains why a suspicious client email needs verification.
