Most Blue Ash law firms adopted Microsoft 365 during the pandemic and never looked back. The problem isn't the platform—it's the configuration. Default M365 settings are built for broad usability, not legal-grade confidentiality. And the gap between "we're on the cloud" and "our client data is actually protected" is where the real risk lives for cybersecurity for law firms in Blue Ash.
What Default Settings Miss
Out-of-the-box Microsoft 365 tenants ship with legacy authentication protocols enabled, minimal conditional access policies, and no restrictions on external sharing. For a small or mid-size law firm in Blue Ash running Clio or iManage on top of an M365 backbone, a misconfigured SharePoint site or an overly permissive OneDrive link can expose client documents without anyone noticing.
The Ohio Rules of Professional Conduct require competent use of technology—and courts have increasingly interpreted that to include reasonable security measures for client communications and files. A breach that stems from a misconfigured cloud tenant isn't just an IT problem; it's a bar complaint waiting to happen.
The Authentication Problem
Legacy authentication (Basic Auth) is still active in many tenants that were migrated rather than freshly deployed. It bypasses multi-factor authentication entirely, meaning a compromised password is sufficient to access email, SharePoint, and Teams. Microsoft has been deprecating legacy auth for years, but firms that migrated piecemeal often have legacy protocols still running for specific accounts or connectors.
Conditional access policies—requiring MFA, blocking sign-ins from unusual geographies, enforcing compliant devices—are available in Microsoft 365 Business Premium but require intentional configuration. Most firms that purchased M365 through a reseller or stood it up themselves have never touched conditional access.
Sharing Links and Matter Files
Legal work involves a lot of document exchange: draft agreements, discovery files, closing documents. The default sharing behavior in SharePoint and OneDrive allows "Anyone with the link" access unless it's been explicitly restricted at the tenant level. That means a paralegal grabbing a quick share link to send to opposing counsel is also creating a publicly accessible URL that doesn't expire and doesn't require authentication.
For firms using NetDocuments or iManage as a document management layer, the risk is partially mitigated—but most Blue Ash firms below twenty attorneys are running directly on SharePoint or local file shares mapped into Teams. Those environments need explicit governance policies applied before they're safe for confidential client matter files.
Email Security Is Still Underbuilt
Phishing attacks against law firms have spiked over the past two years. Legal professionals are high-value targets: they handle real estate transactions, settlements, wire transfers, and sensitive negotiations. Business email compromise (BEC) attacks targeting law firms frequently impersonate opposing counsel or clients to redirect wire instructions.
Microsoft 365 includes Defender for Office 365 in the Business Premium tier, but it requires configuration—anti-phishing policies, safe links, safe attachments. The default state is not fully protective. A firm without a managed IT partner reviewing those settings is likely running with significant gaps.
Layering an endpoint detection platform like SentinelOne EDR through Titan Tech's managed cybersecurity services closes the endpoint side of the equation. For firms that want full visibility into threat activity across the environment, SIEM and MDR coverage provides 24/7 monitoring that catches anomalies—like a user account logging in from two continents in the same hour—before they escalate.
Backup Isn't Included
This is the one that surprises most attorneys: Microsoft 365 does not back up your data. The platform has high availability and a recycle bin, but it is not a backup. Ransomware that encrypts OneDrive, a departing employee who deletes client files, or a sync error that wipes a SharePoint library—none of those are fully recoverable from Microsoft's native tools beyond a short retention window.
A proper backup and disaster recovery solution for an M365 environment means automated daily backups of Exchange, SharePoint, OneDrive, and Teams data to an independent destination—one that isn't connected to the M365 tenant and can't be encrypted by the same attack that hit the primary environment.
What a Proper M365 Security Review Looks Like
A structured review of a law firm's M365 environment covers: legacy authentication status, conditional access policies, external sharing settings, email security configuration, MFA enrollment, admin privilege audit, and backup coverage. It's a half-day engagement that surfaces risk most firms have been carrying for years without realizing it.
For Blue Ash law firms that want their Microsoft 365 environment configured to professional standards—not just running—Titan Tech provides managed M365 services and security hardening as part of our managed IT offerings for the legal industry.
