Email protection
Email & Microsoft 365 Security for Law Firms
Email security for law firms is for firms that need domain authentication hardened and selected Microsoft 365 mailbox controls checked without replacing their existing IT provider. DNS and mail-flow work uses the firm's authorized domain access; mailbox checks are performed only within the agreed scope and authorization.
Law firms move money by email. That makes fake wire instructions and fake partner requests especially dangerous.
Attackers usually do not need to break into your systems. They only need a message that looks close enough to your firm for one person to trust it.
If your MSP runs email day to day, we focus on controls that reduce direct spoofing of your firm's domain, not on ticket handling.
If you want a narrower fix, see our fixed-price one-time services or start with the free Zero-Access Exposure Review™ and we will show you what the public internet already sees. The full services overview is on the services page.
Domain authentication and account sign-in protection address different risks. For the Microsoft 365 side, see our guide to verifying MFA enforcement and account coverage.
The problem
Correct email authentication can reduce direct spoofing of your firm’s domain.
Without the right email settings, anyone on the internet can send a message that appears to come from your firm. The recipient sees a message that looks legitimate because nothing tells their email system to distrust it.
Many firms have partial protection and think they are done. A DMARC setting of p=none only reports suspicious messages; it does not block them. That can look complete on paper while doing very little in practice.
Money moved by wire fraud is often unrecoverable. The loss is not only the client's money. It is the firm's relationship, reputation, and the question of why obvious email controls were never enforced.
DMARC reduces direct spoofing of your firm's domain. It does not stop lookalike domains, compromised accounts, display-name tricks, or every impersonation attempt, so verification and authorized mailbox checks still matter.
What we do
Four steps, staged so the fix does not break the firm.
Step 1
Assess
We inventory every service currently sending mail on your firm's behalf: the mail platform, practice management system, e-signature vendor, billing platform, marketing tools, and any legacy relay.
This inventory is where most DMARC projects fail, because enforcement without it blocks legitimate mail.
Step 2
Configure
SPF is corrected and consolidated, DKIM signing is enabled on every sending service, and DMARC is published in monitoring mode with reporting enabled.
That gives us the baseline before we ask a receiving server to start rejecting anything.
If mailbox forwarding or account controls are in scope, we coordinate the required authorized access with the firm's administrator or existing IT provider.
Step 3
Monitor
We review aggregate DMARC reports during the monitoring period agreed in writing, identify legitimate senders within the agreed scope, and document dependencies and remaining gaps.
The period is set to validate legitimate mail flow before policy enforcement. We do not promise a universal rollout duration.
Step 4
Enforce
DMARC policy is moved in stages toward the agreed target, with verification at each step.
The handoff documents what was changed, what remains dependent on a sender or provider, and what the firm should review next.
What you receive
Documented configuration, validation results, and remaining gaps.
- Full inventory of authorized sending services
- SPF, DKIM, and DMARC configured through a staged path to enforcement
- Before and after evidence of authentication status
- A one-page summary suitable for cyber insurance applications and client security questionnaires
- Lookalike domain findings with a defensive registration priority list
- Written handoff documentation for the firm's IT provider
Who this is for
Use this when email is part of the firm's money movement.
This is a good fit if
- Your firm sends wires, closings, or settlement instructions by email.
- You have more than one system sending mail on your behalf.
- You need evidence that clients and insurers can understand quickly.
- You want the problem fixed in a staged way instead of a rushed DNS change.
This is not the right service if
- You only need a one-time DNS change without sender inventory, monitoring, or agreed completion criteria.
- You are not prepared to inventory every legitimate sender before enforcement.
- You want passive monitoring only rather than a scoped implementation.
Pricing and timeline
Email and Microsoft 365 security, scoped to the work you need.
Email & Microsoft 365 Security is a fixed-quote service. A firm may request email-domain authentication work, mailbox forwarding and inbox-rule review or remediation, sign-in protection, or broader Microsoft 365 configuration.
We confirm the supported sending services, rollout schedule, monitoring period, completion criteria, additional domains, and any third-party costs in writing before work begins.
Final scope and price are confirmed in writing before work begins. The written scope distinguishes email-domain implementation from mailbox remediation and broader Microsoft 365 changes. The Baseline + Email Domain Protection bundle is the separate $1,995 total offer for firms purchasing the $1,495 Baseline and the conditional $500 domain-protection upgrade.
