Signs Your Law Firm Needs a Cybersecurity Assessment Now

Signs Your Law Firm Needs a Cybersecurity Assessment Now

A questionnaire asks whether every account has multifactor authentication. The answer seems easy—until someone asks who checked, which accounts were included, and when.

That is where a law firm cybersecurity assessment can help. It gives leadership a defined, evidence-based view of selected safeguards protecting client information, email, identities, devices, and firm systems. It can also give your MSP or internal IT team a clearer list of items to verify or address.

This is a second set of eyes, not a judgment on your IT provider. The provider keeps running the firm’s systems; the assessment checks an agreed set of security questions. It is not a certification and cannot promise a client or insurer will accept the result.

Signs your firm may need an assessment

You are being asked to show your work

Client questionnaires and insurance applications sometimes ask about MFA, backups, email protection, or incident response. The wording varies, but the follow-up is often the same: what exactly did the firm check?

If no one can identify the systems covered, the person who verified the setting, or the date of the review, pause before treating the answer as confirmed.

Use the law firm client security questionnaire evidence guide to organize evidence and describe unknowns honestly.

The firm has changed, but the review has not

New hires, departures, another cloud service, or a change in IT support can alter who has access and where matter information lives. A review is useful when the firm’s setup has moved on but its documented understanding has not.

You have plenty of reports, but no single answer

Your MSP may already send useful monitoring and support reports. Those reports serve a different purpose from an assessment: they do not always show whether a particular control covers every account, device, or service named in a questionnaire. Agreeing on that scope with your provider helps avoid duplicate work and keeps the review practical.

MFA coverage is based on a product list, not a check

The firm may use MFA and still not know whether it covers every relevant account. Ask whether the review includes administrators, remote access, and exceptions—not just the systems that are easiest to check.

Matter-file access has grown without a recent review

New teams, guest users, and sharing links can make access harder to track. If no one can say who can reach sensitive files or when permissions were last reviewed, that is a good reason to take a closer look.

Nobody has checked how easily the firm’s email domain can be impersonated

SPF, DKIM, and DMARC help receiving mail systems assess messages that claim to come from your domain. If the firm has never checked its sending services and DMARC policy, include email authentication in the review. These settings do not stop every phishing or fraud attempt.

Backups are running, but recovery has not been demonstrated

A successful backup job is not the same as a successful restore. If the firm cannot point to a recent test, say which systems it covered, and identify who owns recovery, the evidence is incomplete.

What a law firm cybersecurity assessment checks

There is no useful answer to “Are we secure?” without defining what was checked. The firm and assessor should agree on the systems and safeguards first. Depending on the engagement, the review may include:

• Email and impersonation protection: SPF, DKIM, and DMARC configuration, authorized sending services, and observable impersonation risks.
• Identity and access: MFA coverage, administrator access, sign-in protections, legacy authentication, guest access, and relevant Microsoft 365 sharing settings.
• Devices and updates: available evidence about endpoint protection, device coverage, patch management, and known exceptions.
• Backups and recovery: backup scope, ownership, and evidence of restoration testing.
• Leadership readiness: incident-response roles, current contacts, and evidence commonly requested by clients or insurers.

The report should be just as clear about what it could not verify. “Not Verified” means there was not enough evidence to reach a conclusion; it does not automatically mean the control failed.

For example, confirming MFA in Microsoft 365 does not establish that MFA is enabled for a separate billing portal or remote-access system. The Microsoft 365 security checklist for law firms covers identity, permissions, mailbox risks, recovery, and device-code phishing.

What the work looks like

First, agree on what is in scope

Before any technical review, the firm and assessor settle the boundaries: which systems and users are included, which records are needed, and what access—if any—is appropriate. The firm’s IT provider should know what is being reviewed and when. That conversation often surfaces a useful question early: does the evidence already exist, or will someone need to gather it?

Then, check settings against the evidence

The assessor looks at the agreed configurations and records. That might mean checking Microsoft 365 settings, email-domain records, device coverage, backup evidence, or incident procedures. A policy can say what should happen; the review asks what the available settings and records show actually happened.

Findings should say what was—and was not—checked

Useful findings name the system or population reviewed, the date of the evidence, and any exceptions. If a check covered only one system, the report should not imply that every system was included.

Imagine a small firm finds that DMARC is set to monitor, MFA coverage for administrators is unclear, external file sharing needs review, and no recent restore test is on record. Those are hypothetical examples, not findings about a particular firm. Each calls for a different next step—and none should be hidden inside a single “secure” or “insecure” label.

Finally, decide what to do first

Leadership needs a short explanation of what matters, why it matters to the firm, and who can take the next step. The IT provider can help estimate and carry out agreed changes. Assessment and remediation are separate work, so confirm who owns each action.

What the assessment does not establish

A cybersecurity assessment is not automatically a penetration test, a legal opinion, or a certification. It cannot prove that every attack will be prevented or that every client or insurer will accept the firm’s answers.

The report should identify its scope and limits. Use the actual wording of a client questionnaire or insurance application, and ask the client, broker, or insurer about requirements that are unclear. The cyber insurance evidence guide for law firms covers careful, evidence-based responses.

If you are not ready to commission a review, the Law Firm Cybersecurity Checklist is a useful first pass. It helps assign owners and request dated evidence. A broader assessment goes further by checking selected controls across an agreed scope.

Choose the right next step

Need a documented review of internal safeguards? Start with the Law Firm Cybersecurity Assessment (Security Baseline). It is designed to work alongside your existing MSP or internal IT team. Any remediation is separately scoped.

If your first question is what an outsider can see online, request the Free Zero-Access Exposure Review™. It checks externally observable conditions. It is not a review of internal safeguards or access to client files.
