Your firm is protected by senior engineers certified in offensive security - people who know how an attacker phishes a paralegal, spoofs a partner, and reroutes a wire, not just what a policy toggle is called.

Who needs law firm cybersecurity

Law firm cybersecurity usually becomes urgent for a concrete reason: a settlement wire nearly went to the wrong account, a corporate client sent a security questionnaire or outside-counsel guidelines you cannot fully answer, a partner’s mailbox behaved strangely, or your malpractice carrier started asking whether you enforce MFA and DMARC. For firms in New York and across the US, the stakes are unusual - you hold privileged material for every client, and a single breach is both a business loss and a professional obligation.

If that is where you are, these are probably your real questions:

If a wire instruction changes by email the day before a closing, what stops it going out?
Can someone spoof our domain and email a client or opposing counsel as one of our partners?
When a client’s security questionnaire lands, can we answer it honestly and fast?
If a laptop is lost or a mailbox is hijacked, is privileged client data actually protected?

How we deliver cybersecurity for legal practices

The same approach fits a boutique or a mid-size firm: understand where privileged data lives, shut down the wire-fraud and email path first, protect access and backups, then arm your people - working hand in hand with the email security and phishing protection your staff see every day.

1. Confidentiality and exposure assessment (about 1 week)

We map where client-privileged material actually lives - email, document management, file shares, laptops, the cloud - and how an attacker would reach it. We review identity and MFA, email authentication, backups, third-party access, and what is exposed to the internet. You get a findings report in plain language: what is at risk, how it would be exploited, and what to fix first.

2. Email and wire-fraud controls

Firms lose the most money to business email compromise - a spoofed or hijacked mailbox that reroutes a settlement or escrow wire. We move SPF, DKIM, and DMARC to enforcement so no one can spoof your domain at clients or opposing counsel, tune anti-phishing and impersonation policies, audit every mailbox for hidden forwarding rules, and set a hard out-of-band rule for verifying any change to payment or trust-account details.

3. Access, encryption, and data protection

Least-privilege access to matter files, enforced MFA, full-disk and mailbox encryption, and tested backups so a ransomware hit or a lost laptop does not become a confidentiality breach. We document who can reach what, and close the gaps that outside-counsel guidelines and client security questionnaires ask about.

4. People, documentation, and questionnaire-ready evidence

We brief attorneys and staff on how phishing and wire fraud actually target law firms, document the controls so your IT team or managed provider can run them, and package the evidence you need to answer client security questionnaires and outside-counsel guidelines quickly instead of scrambling each time one arrives.

Typical time to a protected firm: a few weeks, depending on size and systems.

DMARC to full enforcement runs a little longer to stay safe. The first step is a 30-minute call.

Protecting client confidentiality: what you get

Confidentiality risk findings report - where privileged client data lives, who can reach it, and every gap rated by how an attacker would use it, written for the partners as well as for IT.
Email and wire-fraud protection - SPF, DKIM, and DMARC at enforcement, tuned anti-phishing, a clean sweep of malicious inbox rules, and a verification rule around every trust-account and settlement payment.
Access and data-protection controls - enforced MFA, least-privilege access to matter files, encryption, and tested backups, so a stolen laptop or a ransomware attempt does not expose client confidences.
Client-questionnaire evidence pack - the documentation and answers that let you respond to outside-counsel guidelines and client security questionnaires in days, not weeks.
Attorney and staff briefing - the people who move money and handle privileged files briefed on exactly what a phishing or wire-fraud attempt looks like.

Never had an outside look at how exposed your firm is? A cybersecurity audit is a clean starting point, and the confidentiality gaps it finds feed straight into the controls above.

Wire and escrow fraud: the attack that hits law firms hardest

Business email compromise does more damage to law firms than any other attack, precisely because it does not look like one. There is no malware and no broken firewall - just an email, from a real or spoofed address, changing the wire instructions for a closing, a settlement, or a trust-account disbursement. The money is large, the deadline is real, and a spam filter has nothing to catch. Protection has to be built from layers that each close part of the door.

Make your firm impossible to spoof

SPF, DKIM, and DMARC at enforcement mean no one can send mail that appears to come from your firm - the most common opening move in a wire-fraud scheme, aimed at your clients and opposing counsel as often as your own staff.

Catch impersonation and lookalikes

Tuned anti-phishing policies flag display-name impersonation and lookalike domains, and external mail is tagged, so a message pretending to be a managing partner or a client is obvious to the paralegal reading it.

Find the attacker already inside

When a mailbox is compromised, attackers plant hidden forwarding and auto-delete rules to watch a deal quietly and strike at the wire. We audit every mailbox for them and alert on new rules and suspicious sign-ins so the next one is caught early.

Put a rule around the money

The final control is process: any change to wire, escrow, or trust-account details is verified out of band, on a known number, before it moves. We set the rule and brief the attorneys and staff it protects.

This is not theory. We removed attackers from a client’s mail systems and stopped a fraud in progress in four hours - the full account is in the BEC case study. If an attack is live right now, our incident response team is where to start.

Law firm data protection and ABA cybersecurity expectations

Security is not just good practice for a firm - it is tied to your professional duties. The ABA’s guidance connects it to the duty of technology competence under Model Rule 1.1 and the duty of confidentiality under Model Rule 1.6, which expects reasonable safeguards for client information and, in its formal opinions, prompt and careful handling if a breach occurs. Corporate clients increasingly turn the same expectations into contract terms through outside-counsel guidelines and security questionnaires.

We build the controls that satisfy both - enforced MFA and least-privilege access to matter files, encryption of laptops and mailboxes, email and wire-fraud protection, tested backups against ransomware, and staff training - and we produce the documentation that shows you took reasonable steps. Where a client wants a recognized attestation, we guide firms through SOC 2 compliance. We are your security partner and translate the technical side into evidence; your obligations under the rules of professional conduct remain yours to interpret.

What law firm cybersecurity is not

“Security” is sold to firms in a lot of ways that do not actually protect a client’s confidences. We work differently: we harden what you already own.

So you know exactly what you are buying, we are just as clear about what you do not get:

It is not a product we resell.

We do not sell you a security appliance, a license, or a subscription and mark it up. We harden the platforms your firm already runs - Microsoft 365 or Google Workspace, your document management, your identity - and configure the protections most firms never turned on. Vendor-neutral, on your own systems.

It is not a compliance checkbox.

A generic policy template does not stop a hijacked mailbox from rerouting an escrow wire, and it does not satisfy a client who asks how you actually protect their data. We fix the controls behind the questions, then give you the evidence to answer them honestly.

It is not a one-time project you forget.

Configuration closes most of the door; the last gap is human and ongoing. We brief your people, and for a standing program we point you to security awareness training and phishing protection - the technical and human controls work together, they do not replace each other.

Frequently asked questions

What does cybersecurity for law firms actually cover?

It is the assessment and configuration work that keeps privileged client information out of an attacker’s reach: mapping where matter files and email live, enforcing MFA and least-privilege access, moving SPF, DKIM, and DMARC to enforcement so no one can spoof your firm, putting protection around trust-account and settlement wires, testing backups against ransomware, and documenting all of it so you can answer client security questionnaires. We do this on your own Microsoft 365 or Google Workspace tenant and your existing systems - it is advisory and hands-on configuration, not a product we resell.

How do you protect against wire and escrow fraud at a law firm?

Wire and escrow fraud is almost always business email compromise: an attacker spoofs or takes over a mailbox and reroutes a settlement, closing, or trust-account payment with an email that looks completely legitimate and never trips a spam filter. Our protection layers several controls - DMARC enforcement so your domain cannot be spoofed, tuned impersonation and anti-phishing policies, an audit of every mailbox for the hidden forwarding rules attackers plant, sign-in alerting, and a hard process rule that any change to payment or trust details is verified out of band on a known number before it moves. We stopped a live business email compromise attack at a client in four hours - see the BEC case study.

A client sent us a security questionnaire or outside-counsel guidelines. Can you help us answer it?

Yes - this is one of the most common reasons firms call us. We assess your current controls against what the questionnaire or outside-counsel guidelines actually ask, fix the gaps that matter, and package the evidence so you can answer honestly and quickly. If a client also expects a recognized attestation, we guide firms through SOC 2 compliance - increasingly what larger corporate clients want to see before they hand a firm their data.

What does the ABA expect law firms to do about cybersecurity?

The ABA’s guidance ties security directly to your professional duties: the duty of technology competence under Model Rule 1.1 and the duty to protect client confidentiality under Model Rule 1.6, which expects reasonable safeguards for client information and, in several formal opinions, prompt handling of a breach. In practice that means MFA, encryption, access controls, email protection, tested backups, staff training, and the documentation to show you took reasonable steps. We build those controls and the evidence, mapped to what your clients and your obligations actually require - we are your security partner, not your ethics counsel.

We are a small firm with an outside IT provider. Do we still need this?

Usually yes. Most managed IT providers keep the lights on - they are not offensive-security specialists, and the controls that stop wire fraud and protect privilege are exactly the ones commonly left on defaults: DMARC is rarely at enforcement, impersonation protection is rarely tuned, mailbox auditing goes unread, and backups are rarely tested with a real restore. We work alongside your provider, not over them, and hand back documented controls they can maintain. Firms from a handful of attorneys up to a few hundred staff are squarely who this is for.

How long does it take, and what does it cost?

For a typical firm, expect a few weeks: about a week for the assessment, then the email, access, and data-protection work staged over the following weeks so nothing legitimate breaks. DMARC to full enforcement runs a little longer because it waits on a monitoring window. Cost depends on your size and systems, which is what the 30-minute call is for - at the end of it you receive a fixed quote scoped to your environment within 24h.
