Common Questions

Frequently Asked Questions
From Law Firms

Why are law firms increasingly targeted by cyber attackers?+
Law firms concentrate high-value information: M&A details, IP disputes, government investigations, sanctions advice, and personal information for thousands of individuals. Privilege rules also mean firms cannot publicly disclose breaches the way other industries might. This combination makes law firms attractive to both criminal and nation-state actors. Many firms also operate with thinner security investment than the clients they serve, widening the gap.
What client security questionnaires should we be ready for?+
Most enterprise clients now send security questionnaires before engaging a firm on sensitive matters. These typically map to SOC 2, ISO 27001, or NIST CSF controls and cover access management, encryption, incident response, vendor risk, business continuity, and security testing. Our Compliance Audit service prepares firms with documented controls and evidence specifically structured to respond to these questionnaires efficiently.
How does Law Society confidentiality obligation translate to cybersecurity?+
Provincial Law Society rules require lawyers to take reasonable steps to protect client information, which courts and regulators have increasingly interpreted to include technical and administrative cybersecurity controls. The standard is not a specific framework but a duty of competence that includes understanding the risks of technology you use. We help firms document the controls and the reasoning behind them so the duty is demonstrably met.
Can you help us respond to a cyber incident in progress?+
Yes. We support incident response in the same way our vCISO and managed-security clients receive it: triage, scoping, containment, evidence preservation, regulator and Law Society engagement support, client communication review, and post-incident remediation. For active incidents involving privilege concerns, we coordinate with your insurance carrier and counsel to preserve privilege over investigation work product.
Do we need a vCISO if our firm has a Managing Partner overseeing IT?+
Managing Partners typically lack the bandwidth and specialized expertise that cyber governance requires. A vCISO complements rather than replaces firm leadership: senior cybersecurity expertise applied a few days a month, with board and partner-level reporting, audit oversight, vendor risk, and incident readiness. The vCISO works alongside your existing IT and management team.
How do we protect privilege when working with an external cybersecurity firm?+
We work under NDAs and engagement letters structured to support attorney work product and privilege over investigation findings. Our consultants are familiar with the legal duty of competence and the need to preserve privilege over incident response activity. Where appropriate, we deliver findings to outside counsel rather than directly to the firm, supporting the privilege framework.
Do you have experience with smaller firms and boutiques?+
Yes. Solo practitioners and boutique firms typically engage us through Armour 360 for managed cybersecurity coverage plus a fractional vCISO at minimal monthly commitment. Mid-size firms (25-150 lawyers) add Compliance Audit and Penetration Testing for client RFP responses. The economics scale with firm size, not just headcount.
