Protect Client Confidentiality.
Satisfy Your Bar Obligations.
Cybersecurity and compliance-aware IT for law firms of all sizes. We build environments that keep privileged information privileged, not just at setup, but continuously.
Who We Serve
NTG provides managed IT and cybersecurity services to law firms that understand client confidentiality is not just an ethical obligation. It is an operational and legal one. We serve solo practitioners, boutique firms, regional practices, and multi-office firms across the country, in practice areas ranging from litigation and corporate law to healthcare, real estate, employment, and criminal defense.
Law firms are high-value targets for cybercriminals. You hold sensitive client information, financial data, privileged communications, and in many cases information that directly affects ongoing litigation, transactions, or regulatory matters. NTG builds IT environments that protect that information and keep it protected, not just at setup, but continuously.
What We Deliver
What NTG Delivers for Law Firms
Bar Rule Compliance Confidence
We build and document the security posture that satisfies ABA Rule 1.6 and your state bar's cybersecurity guidance. If you are ever asked to demonstrate reasonable efforts, you have the evidence.
Client Confidentiality Protection
Encrypted communications, access-controlled file systems, and monitored endpoints ensure that privileged client information stays privileged.
Breach Response That Protects the Firm
When an incident occurs, how you respond determines your exposure: to clients, to the bar, and to regulators. NTG provides defined incident response with documentation that supports your obligations.
Client-Facing Security Posture
Increasingly, sophisticated clients: especially in healthcare, finance, and defense: ask their outside counsel about cybersecurity practices before engaging. NTG gives you a documented, credible answer.
Nationwide Support with Local Coverage
Multi-office firms have one accountable IT partner. Remote management handles the majority of support; vetted local technicians handle onsite needs at any location across the country.
IT That Understands Legal Operations
Document management systems, legal research platforms, practice management software, and remote attorney access all require specific IT expertise. Legal practice operations are central to what we do.
Compliance Landscape
The Compliance Landscape for Law Firms
Law firms face a layered set of obligations: some explicit, some that flow from the clients they represent. Most firms are subject to more of these than they realize.
| Obligation Source | What It Requires | Applies To |
|---|---|---|
| ABA Model Rule 1.6 | Reasonable efforts to prevent unauthorized disclosure of client information. Interpreted to require encryption, MFA, and documented security practices. | All firms in all states. Most states have adopted equivalent rules. |
| State Bar Rules | Many state bars (NY, CA, FL, TX, and others) have issued cybersecurity guidance or formal opinions specifying what 'reasonable efforts' means in practice. | All firms. Requirements vary by state and practice area. |
| State Breach Notification Laws | All 50 states require notification to affected individuals when personal information is compromised in a breach. Timelines range from 30 to 90 days. Some states require notifying the state AG. | All firms handling personal information about individuals, which is virtually every firm. |
| NY SHIELD Act | Requires any business handling data of New York residents to implement reasonable cybersecurity safeguards, regardless of where the firm is located. | Firms with New York clients or New York-based individuals in their files. |
| California CCPA / CPRA | Grants California residents rights over their personal data and requires businesses above certain thresholds to implement data security and respond to consumer requests. | Firms with California clients meeting revenue or data volume thresholds. |
| HIPAA (Flows from Clients) | Firms representing healthcare clients who receive or handle protected health information (PHI) may be Business Associates under HIPAA: requiring a BAA and security controls. | Firms serving hospitals, clinics, health plans, or other covered entities. |
| FTC Safeguards Rule (Flows from Practice) | Law firms providing certain financial services: tax planning, estate planning involving financial products: may qualify as financial institutions under GLBA. | Firms with financial services practice areas. |
| ITAR / CUI (Flows from Clients) | Firms representing defense contractors or handling export-controlled or Controlled Unclassified Information may be subject to ITAR or CMMC-adjacent requirements. | Firms serving defense industry or government contractor clients. |
| Cyber Insurance Requirements | Insurers now require MFA, EDR, encrypted backups, and incident response plans as conditions of coverage. Firms that cannot demonstrate these controls face higher premiums or coverage denial. | All firms carrying cyber liability insurance, which should be every firm. |
The critical point: a law firm representing a hospital, a DoD contractor, or a financial institution is handling information subject to those clients' regulatory obligations, often with far weaker security controls than the clients themselves maintain. That exposure is real, and it is increasingly what opposing counsel, regulators, and insurers are looking at.
Gap Analysis
The Most Common Security Gaps We Find in Law Firms
Unencrypted Email Used for Client Communications
ABA guidance is clear that email transmitting sensitive client information should be encrypted. Most law firms still rely on standard unencrypted email for client communications, document transfers, and settlement discussions.
No Multi-Factor Authentication on Remote Access
Attorneys working remotely: from home, hotels, or court: frequently access firm systems with passwords alone. A single compromised password can expose every client file the attorney can access.
Client Files Stored Without Access Controls
Shared drives where every staff member can access every client's files are the norm at many firms. Role-based access: where each person sees only what they need: is required for proper confidentiality management and is expected under bar rules.
No Documented Incident Response Plan
Most firms have no written process for what to do when something goes wrong. Without a documented plan, firms miss notification deadlines, fail to preserve forensic evidence, and make decisions under pressure that create additional liability.
Personal Devices Used for Client Work Without Controls
Attorneys using personal laptops and phones for client work: without encryption, remote wipe capability, or endpoint protection: create significant confidentiality exposure. Mobile device management (MDM) is rarely implemented at smaller firms.
No Vendor Review for Third-Party Tools
Law firms use cloud-based practice management, document storage, and communication tools: often without reviewing the vendor's security practices or executing data processing agreements. Bar guidance increasingly requires oversight of third parties handling client data.
Bar Rule Compliance
What "Reasonable Efforts" Means in Practice
ABA Model Rule 1.6(c) requires attorneys to make reasonable efforts to prevent the inadvertent or unauthorized disclosure of client information. Here is what the guidance consistently identifies as components of reasonable efforts.
Preventive Controls
- Encryption of client data at rest and in transit, including email, file storage, and portable devices
- Multi-factor authentication on all systems used to access client files remotely
- Role-based access controls limiting who within the firm can access which client files
- Endpoint protection on all devices used for client work, including personal devices
- Secure client portals for document exchange rather than unencrypted email attachments
Oversight and Vendor Management
- Review of cloud service providers and legal technology vendors handling client data
- Data processing or confidentiality agreements with vendors who access client information
- Understanding of where client data is stored, who can access it, and how it is protected
Incident Preparedness
- Written incident response plan with defined steps for detection, containment, and notification
- Knowledge of applicable state breach notification deadlines for your jurisdiction and your clients' jurisdictions
- Understanding of whether and when the state bar must be notified of a breach affecting client data
- Documented evidence of security practices that demonstrates reasonable efforts were made
Staff Training
- Annual security awareness training for all attorneys and staff with access to client information
- Specific training on phishing and business email compromise: the leading cause of law firm breaches
- Clear policies on acceptable use of personal devices for client work
