Threat & Risk Assessment for Law Firms
Identify, prioritize, and act on security risks across your organization in Law Firms.
Law firms hold information that is, by legal definition, among the most protected that exists: solicitor-client privileged communications, litigation strategy, transaction documents, and personal details about individuals in some of the most difficult circumstances of their lives. That protection exists because the legal system depends on clients speaking candidly with their lawyers. A security failure that exposes privileged communications doesn't just breach privacy law — it compromises the foundational principle that makes legal representation work.
Law firms — particularly those handling corporate transactions, real estate closings, and high-value litigation — are a well-established target for business email compromise. The mechanism is specific: attackers monitor email between a firm and its clients, wait for a transaction to reach the point where wire instructions are exchanged, and insert fraudulent instructions that redirect funds. The technical investment required is modest. The financial consequences for the firm, and the damage to the client relationship, are not.
Law Society obligations in each province require firms to take reasonable steps to protect client confidentiality — a standard that implies having assessed what those steps should be. The obligation is not satisfied by the absence of a known incident; it requires documented measures proportionate to the sensitivity of what is held. For firms that have grown organically, that documentation is often exactly what is missing: reasonable controls may exist, but the assessment that established them typically does not.
Privacy Horizon's TRA gives law firms the structured assessment their professional obligations require. We map the full threat surface — email infrastructure, client file systems, cloud document tools, and the legal technology platforms central to modern practice — and conduct a vulnerability analysis calibrated to BEC, ransomware, and unauthorized access threats. The risk register and remediation roadmap are written for firms focused on practicing law, not managing IT programs: plain, prioritized, and executable by a small team or an external provider.
Why Threat & Risk Assessment matters for Law Firms
Law Society obligations in every province require firms to take reasonable steps to protect client confidentiality — a standard that demands an actual assessment of what those steps should be, not merely the absence of a known incident. The threat actors targeting law firms are well-practised: business email compromise in transaction matters, ransomware targeting client file systems, and unauthorized access to privileged communications are all documented attack patterns with documented consequences. A TRA provides the assessment that Law Society guidance increasingly expects firms to have completed, and the remediation roadmap that puts the identified gaps in a manageable sequence — particularly important for firms without dedicated security staff.
Law firms hold solicitor-client privileged communications, litigation strategy, corporate transaction documents, and personal information about individuals in some of the most sensitive circumstances of their lives — making them a high-value, frequently targeted sector. The Law Society obligations in each province require firms to take reasonable steps to safeguard client confidentiality, and regulators have issued specific guidance on cybersecurity. Despite this, many firms — especially small and mid-size practices — lack mature security programs proportionate to the sensitivity of the data they hold.
Relevant frameworks: Law Society cybersecurity and professional responsibility obligations (provincial), PIPEDA / provincial private-sector privacy laws, ISO 27001, SOC 2 Type II (for legal technology vendors)
Our approach for Law Firms
We begin with asset and threat identification focused on the data categories that define legal practice: client communications, matter files, transaction documents, and the technology platforms — email systems, document management, cloud collaboration tools — through which those assets flow. Threat analysis is calibrated to BEC, ransomware, and insider access risks specific to law firms. Vulnerability analysis examines email security controls, access management for client file systems, cloud document governance, and the third-party legal technology integrations that have extended your data footprint. The risk register and remediation roadmap are written for firms without dedicated security teams — prioritized clearly, scoped practically, and directly actionable by your existing IT support.
What Threat & Risk Assessment includes
