Cybersecurity cost is the first question most firm administrators ask, and the hardest to get a straight answer to — vendors hide pricing behind a sales call, or quote enterprise figures built for AmLaw-sized firms. So here are the actual ranges for the solo, small, and midsize firms that make up most of the market.
The Short Answer
For a solo or small firm, managed cybersecurity typically runs $375 to $799 per month. A multi-attorney practice usually sits in the $800 to $1,400 per month range, and a larger midsize firm with a document-management system and more support staff runs roughly $1,400 to $2,375 per month. Those are managed figures — a provider who deploys, runs, monitors, and responds — not a stack of licences the office manager administers.
Why It's Priced by Firm Size
Nearly all of the cost tracks the number of devices protected (attorney and staff computers) and user accountssecured (email, the document-management system, cloud logins). A solo practitioner has a handful; a twenty-attorney firm has many more. Pricing scales with the firm because the work does — which is also why a flat “firm security package” price is a red flag in either direction.
What the Monthly Fee Should Include
A fair managed price should cover the controls that actually prevent the incidents firms suffer — and that support the ethical duty to safeguard client information:
What a Managed Plan Should Cover
- Managed endpoint detection & response (EDR) on every attorney and staff device
- Multi-factor authentication on email, the document-management system, and admin accounts
- Email security with wire-fraud and impersonation (BEC) defence
- Encryption of client files in transit and at rest, with access logging
- Offsite, immutable, tested backups of matter files and core data
- 24/7 monitoring, security awareness training, and an incident response plan
The Number That Actually Matters: One Redirected Wire
A monthly fee feels like pure cost until you weigh it against the alternative. A single intercepted settlement or trust-account transfer can run to six figures and is often unrecoverable once it's gone. A ransomware event mid-litigation can halt a firm against immovable court deadlines. And a breach of privileged data can bring a bar complaint and lasting reputational harm on top of the direct loss. Against any of those, a managed program in the hundreds-to-low-thousands per month is a small, predictable cost. We walk through how the wire scam works in wire fraud at closing.
How to Spend the First Dollar Well
If the full managed range isn't in budget yet, start with the highest-value controls: multi-factor authentication on email and the document system, modern EDR on every device, a verification procedure for any trust or settlement transfer, and tested offsite backups. Those are the core of an Essential-tier plan and stop the attacks that begin most legal incidents.
The Bottom Line
Cybersecurity for a law firm isn't an enterprise expense — it's a predictable operating cost in the $375–$2,375 per month range, scaled to firm size, that protects privileged data and supports your duty of competence.
