How we help legal buyers source technology.

Privilege-protected operations · Multi-office firms.

TL;DR

What buyers in legal need to know.

Legal services firms source technology under attorney-client privilege constraints that shape every vendor selection. The vendor that can't survive a privilege-review conversation isn't the right vendor. The good ones know exactly what that conversation looks like before you ask.

The pain points

What's actually broken in legal technology sourcing right now.

Specific to this industry. We see the same five problems across nearly every engagement.

Vendors who cannot survive privilege review at contract redline.
Discovery-readable retention configurations that vary by jurisdiction.
ABA Opinion 483 compliance costs nobody budgets for in advance.
Practice-management system integrations that look productized and are not.
Multi-office voice that fails the same way in every office of every firm.

The vendor landscape.

Categories we source for legal: Privilege-aware UCaaS · CCaaS for client intake · MSSP for legal-data protection · multi-office SD-WAN · document-management integration.

Regulatory environment: Attorney-client privilege, work-product doctrine, state-level bar association data-handling rules, ABA Model Rules of Professional Conduct, increasing state-level breach-notification rules.

Integration dependencies: Practice-management systems (Clio, MyCase, PracticePanther, Centerbase), document-management systems (NetDocuments, iManage, Worldox), time and billing systems, e-discovery platforms.

Every vendor mentioned in the questions below is in our active supplier pool. Buyer-stack software (EHR, ERP, AMS, DMS, and similar) is named freely as integration targets — these are systems we source contracts to integrate WITH, not vendors we source ourselves.

Three questions buyers actually ask

The high-intent questions answered.

What does a privilege-protected UCaaS deployment look like for a 100-attorney firm?

Mid-size law firms need UCaaS with discovery-readable retention controls, sub-processor disclosure that survives a privilege review, and integration with practice-management systems. RingCentral, 8x8, Zoom Phone, and Webex Calling all carry mature legal configurations. The differentiator is the retention configuration and the Microsoft 365 integration.

How do we source CCaaS for client intake at a litigation-heavy firm?

Litigation-heavy firms with client-intake CCaaS need to handle high call volume during marketing campaigns, integrate with case-management systems, and produce conflicts-checking workflows. Talkdesk, Five9, and Nextiva CX all carry legal-specific configurations with Clio and MyCase integrations. The differentiator is the intake-form integration and the conflicts-checking workflow.

What does an MSSP look like for a law firm under ABA Formal Opinion 483?

ABA Formal Opinion 483 raises the bar on attorney cybersecurity obligations. Mid-size firms need 24/7 SOC, incident response with notification-decision support, MFA on all client-data systems, and annual penetration testing. Trustwave, SilverSky, and Coro carry legal-specific MSSP packages.
