IT Support for Law Firms

What IT support for law firms covers

IT support for law firms combines ordinary office IT with a heavier emphasis on confidentiality, records and money movement. Attorneys bill by the hour, so downtime has a visible price, and the firm holds information that clients, courts and opposing counsel all care about.

The usual scope of IT services for law firms:

• Help desk for attorneys, paralegals and staff, including after-hours support around filing deadlines and trials.
• Document management and practice management system support.
• Secure email, encrypted file sharing and a client portal.
• Laptops and remote access for attorneys working from court, home or client sites.
• Backups, retention and the ability to place data on legal hold.
• Security monitoring, phishing training and incident response planning.

Providers' published pricing guides list fully managed IT at $100 to $250 per user per month, and plans with more security tooling reach $300 or more ¹². Hourly break-fix work runs $75 to $250, with emergency rates of $300 or more ¹. Our managed IT services pricing guide explains what drives the range.

Client confidentiality and the duty to protect data

Lawyers have a professional duty to protect client confidences, and in practice that duty now runs through the firm's computers, email and cloud accounts. State bar rules and ethics opinions set out what is expected, and they differ by state, so ask your own bar or ethics counsel what applies to your firm.

What that duty means for IT decisions:

• Know where client data lives. Email, document management, laptops, phones, a scanning workstation, personal cloud accounts. You cannot protect what you have not listed.
• Limit access by matter when ethical walls or client terms require it.
• Question vendors. Any cloud system or IT provider that holds client files should explain, in writing, how it protects them and who on its staff can see them.
• Encrypt devices so a lost laptop is an inconvenience rather than a disclosure.
• Plan for a breach before it happens, including who decides what clients must be told.

Many firms now get the same questions from corporate clients in outside counsel guidelines and security questionnaires. Having MFA, EDR, tested backups and a written incident response plan in place answers most of them, and those are the same controls insurers treat as minimums ⁴.

Wire fraud and business email compromise

Business email compromise is the cyber threat most likely to cost a law firm real money. The FBI's Internet Crime Complaint Center received 24,768 BEC complaints in 2025 reporting about $3.05 billion in losses ³. In Coalition's 2026 claims report, BEC and funds transfer fraud made up 58% of incidents among its policyholders ⁵.

Firms that handle real estate closings, settlements, trust account disbursements or escrow carry the most exposure. The pattern is consistent: an attacker gets into a mailbox (the firm's, the client's or the other side's), watches a matter, then sends new wiring instructions at the right moment.

Controls that stop most attempts:

• MFA on every mailbox. Microsoft research found MFA reduces the risk of account compromise by 99.22% ⁶.
• Email security that flags lookalike domains and external senders. Microsoft Defender for Office 365 lists at $2 to $5 per user per month ⁷.
• Callback verification of any wiring change, using a number already on file.
• Alerts on mailbox forwarding rules and sign-ins from unusual places.
• Staff training focused on payment requests, not generic phishing slides.

If money has already moved, call your bank immediately to request a recall, report to the FBI at ic3.gov ³, and contact your cyber insurer's hotline if you have a policy. Do not delete the emails or reset the mailbox before evidence is preserved. Our incident response guide explains the next steps.

Document management for law firms

A document management system is the center of law firm IT: it stores pleadings, correspondence and work product by client and matter, keeps versions, and controls who can open what. Firms that rely on shared network drives and email attachments usually hit three problems: lost versions, no matter-level security, and no way to find everything when a client asks for its file.

What an IT provider should handle around document management:

• Matter-centric structure and permissions, including ethical walls where needed.
• Email filing so correspondence lands in the matter, not in individual inboxes.
• Retention rules that match your records policy and any client requirements.
• Integration with your practice management, billing and e-signature tools.
• Backups of the document system itself. A cloud service is not the same as a backup; third-party Microsoft 365 backup starts around $2 to $3 per user per month at list ⁸.

Moving from file shares to a proper document system is a project, not a ticket. Get a fixed scope and price, a plan for migrating old matters, and training time for attorneys. Our backup and disaster recovery guide covers how to protect the system once it is live.

E-discovery basics for small and mid-size firms

E-discovery is the process of identifying, preserving, collecting, reviewing and producing electronically stored information in litigation. Most small firms buy review platforms and processing from specialist vendors, but the firm's own IT setup decides how easy the early steps are.

Where IT support matters:

• Legal holds. Your email and document systems should be able to preserve a custodian's data so it cannot be deleted, without copying everything by hand. Check whether your current email and file platform plan includes hold features before you need them.
• Defensible collection. Pulling a client's or custodian's data in a way that keeps metadata intact and can be explained later.
• Secure transfer of large productions to vendors, co-counsel and opposing counsel, rather than email attachments or personal file-sharing links.
• Retention clarity. A written schedule for what the firm keeps and for how long makes it easier to answer discovery about the firm's own records.

Ask any IT provider whether it has set up legal holds for another firm, and which e-discovery vendors it has worked with. An IT provider is not a substitute for a litigation support specialist, but it should make that specialist's job easier.

Cybersecurity for law firms: what to buy first

Start with the controls that block the most common attacks, then add monitoring once the basics are in place. For a firm of 5 to 50 people the sequence that makes sense for most is:

1. MFA everywhere, starting with email and remote access.
2. Endpoint detection and response on every laptop and server. EDR tools list at $3 to $20 per endpoint per month ⁹.
3. Email security and payment verification procedures.
4. Encrypted, tested backups of email, documents and the practice management system.
5. Phishing training. Published list prices run about $2.40 to $3.75 per seat per month for small teams ¹⁰.
6. Managed detection and response, so someone watches alerts at night. For a small firm that usually means $8 to $25 per endpoint per month ¹¹.

Cyber insurers expect most of this list. In Travelers v. International Control Services, the insurer sought to rescind a $1 million policy after a ransomware attack, alleging the insured misstated its MFA coverage on the application ¹². Answer insurance questionnaires carefully.
