A Florida law firm data breach response should begin with coordinated action, not guesswork. When unauthorized access to client data is suspected, the firm needs to limit further access, preserve useful records, and quickly involve the people who can assess the incident and its obligations.
Not every cybersecurity incident is a breach under Florida’s notification law, and not every exposure of confidential legal material is the same kind of event. A firm may still have ethical, contractual, client, or other obligations to consider. Treat the technical investigation and legal assessment as related but distinct workstreams, and involve counsel promptly.
First actions: contain access and preserve information
Activate the response lead
Notify the person responsible for incident response at the firm and establish who is coordinating decisions. Depending on the situation, that group may include firm leadership, internal or outside counsel, the IT provider, the insurer, and affected service providers. Keep the response team focused on verified facts and record who is making decisions.
Use a communication channel that is not suspected of being affected. If firm email or messaging may be compromised, ask the response lead or IT provider to arrange a trusted alternative. Avoid sending sensitive client details through a channel that has not been assessed.
Contain affected access with technical help
Ask qualified IT responders to identify the affected accounts, devices, systems, and data, then take containment steps suited to the circumstances. These could include restricting a compromised account or isolating a device from the network. The right step depends on what is affected and how the incident is unfolding.
Do not reflexively wipe a device, delete messages, or make broad changes before coordinating with responders. A rushed reset or shutdown can remove information that could help establish what happened. If there is an immediate risk of continued access, prioritize safe containment while coordinating evidence preservation with the response team. The CISA incident response playbooks provide additional guidance for organizing response actions.
Preserve relevant records
Ask responders to preserve available system, account, email, network, and application logs, along with relevant alerts and access records. Keep original files and devices intact when practical, and document what was collected, when, and by whom. Preserve related communications, suspicious messages, and a timeline of observed events. Avoid routine cleanup or log rotation changes that could overwrite information before responders have assessed it.
Document what the firm knows, what remains uncertain, and when each fact was identified. Separate confirmed observations from assumptions. This record can help counsel and technical responders assess the scope without turning early guesses into conclusions.

Assess what information and obligations may be involved
Map the potentially affected data
Determine which systems and matters may be involved, what categories of information were accessible, and whether there is evidence that information was viewed, acquired, changed, or shared. Look for affected client files, email, case management systems, e-discovery materials, backups, and shared workspaces. Preserve relevant matter records and litigation hold information rather than changing them as part of routine cleanup.
Keep the review appropriately narrow and controlled. The investigation may involve privileged material, confidential client information, or sensitive case strategy. Counsel can help guide how findings are documented and shared. The considerations for protecting attorney-client confidentiality may also help firms think through information handling.
Ask counsel to assess notification duties promptly
Florida Statute § 501.171 applies to specified personal information and has defined conditions for notification; an incident involving confidential legal material does not automatically mean the statute applies. Counsel should assess the facts, the information involved, whether the statutory definition is met, and any applicable exceptions.
For specified notices, the statute generally sets a 30-day outside limit after determination of a breach or reason to believe one occurred, while requiring notice as expeditiously as practicable and allowing defined exceptions or delay procedures; counsel should assess how the requirements apply to the incident. Read Florida Statute § 501.171 and consult counsel promptly rather than treating the end of a technical investigation as the start of the assessment.
Separately, consider professional confidentiality obligations, client agreements, outside-counsel requirements, and any sector-specific requirements that may apply to a client or matter. The Florida Bar’s cyber resilience guidance offers a framework for law firms to consider as they plan and respond. It does not replace advice tailored to the facts of an incident.
Include cloud, email, and AI providers in the response
If a third-party service may be involved, identify the provider, affected account or workspace, data stored or processed there, and any available access or activity records. Contact the provider through a trusted channel and ask it to preserve relevant logs and explain what response steps it has taken. Review applicable service terms, client contracts, and reporting procedures with counsel.
If the incident involves an AI tool, determine what information was entered, which account or service was used, and whether the provider offers records that can help establish access or activity. Do not assume that a service’s data-handling terms or technical controls resolve the firm’s responsibilities. Consider whether client instructions or other requirements affect the response.
Coordinate communications and recovery
Have counsel guide decisions about notifying clients, regulators, law enforcement, insurers, or other parties. Do not send broad or speculative notices before the facts and applicable duties have been assessed, but do not let uncertainty become a reason to postpone that assessment. Keep communication accurate, limited to what is known, and consistent with the response plan.
Before restoring normal access, responders should address the suspected path of entry and confirm that affected accounts and systems can be used safely. The firm can also review whether case management, e-discovery, and litigation hold workflows remain reliable. Zevonix’s experience includes supporting e-discovery workflows and helping firms keep case management systems running during trial preparation, which are considerations when restoring legal operations.
Frequently asked questions
Should a firm disconnect a compromised computer or account?
Containment may involve isolating a device or restricting an account, but coordinate with qualified responders when possible. The response team can help reduce ongoing access while preserving information needed to investigate.
How can a firm preserve logs and other evidence?
Ask responders to preserve available records before routine cleanup or changes overwrite them. Keep original materials when practical, document collection and handling, and maintain a timeline of observations and decisions.
When does Florida’s notification deadline start?
The statute’s specified notice period is tied to the determination of a breach or reason to believe one occurred, not simply to completion of the technical investigation. Counsel should assess when the relevant standard is met and which notice requirements apply.
Does every unauthorized disclosure trigger Florida’s breach notification law?
No. The statute covers specified personal information and has defined conditions. An incident may raise other confidentiality, ethical, contractual, or client obligations even if counsel determines the statute’s notification provisions do not apply.
Who should a firm contact first?
Notify the firm’s response lead and involve counsel and the IT responders who can safely contain access and preserve records. The right participants depend on the systems, data, and agreements involved.
Take the next step
A disciplined first response helps a Florida law firm contain access, preserve useful evidence, and give counsel a clearer basis for assessing obligations. Review your incident process before an event occurs, and contact your IT provider or Zevonix if your firm needs help preparing to respond to unauthorized access.
