Privacy & Security for Consulting & Advisory Firms
A consultancy holds almost no consumer data of its own, yet it carries its clients' most sensitive material: financials, strategy decks, M&A data-room exports and employee datasets. That is why your obligations arrive through MSAs, RFPs and your clients' regulators rather than from a privacy statute knocking on your own door. Privacy Horizon builds the privacy and security program that lets a Canadian advisory firm clear a bank client's OSFI B-10 review, answer an RFP security schedule and meet Quebec Law 25 duties, and we usually start the week a client questionnaire lands.

Who this is for
We work with Canadian management, strategy, HR and compensation, finance and transaction, IT-advisory, economic and research consultancies, from boutiques of five people to regional firms of three hundred.
The people who call us are the managing partner whose bank client just invoked its third-party risk program, the engagement partner handed a 200-question questionnaire in the middle of delivery, the bid manager facing an RFP that scores certifications, and the COO who discovered the Montreal office needs a named privacy officer.
Most of these firms have no internal security team. IT is an outsourced MSP, files live in Microsoft 365 and client data rooms, and consultant laptops travel between client sites, home offices and airport lounges. Our job is to make that reality defensible on paper and in practice.

What you hold
What an advisory firm holds that others never touch
The paradox of consulting is that your riskiest records belong to other organizations. A neighbourhood retailer protects its own customer list; you protect the board papers of yours.
Client confidential business information
Financial models, strategy decks, board materials and M&A data-room exports sit in your SharePoint and on partner laptops, all held under engagement letters and NDAs that promise more care than most firms actually document.
Client employee and customer datasets
HR, compensation and engagement-survey mandates mean spreadsheets of someone else's staff, and CX or analytics work means their customer records. Under PIPEDA the client stays accountable, and their contract makes you carry the duty.
Interview notes, recordings and survey responses
Stakeholder interviews and recorded workshops capture candid statements from identifiable people. They rarely appear in any data inventory, yet they are personal information in your custody.
Proposals, pricing and bid material
Your own commercial secrets, competitive pricing, win themes, teaming arrangements, are exactly what an extortion crew publishes first to force payment.
Cleared personnel and subcontractor files
Firms doing federal work hold records tied to reliability status and organization screening, plus subcontractor security paperwork that flows down from the prime contract.
Regulatory map
Why the audit comes from your client, not a regulator
No self-regulator disciplines consultancies the way a law society disciplines lawyers. Your enforcement mechanism is contractual: a client's regulator pushes duties onto the client, and the client pushes them into your MSA.
OSFI Guideline B-10 reaches you through bank clients
Federally regulated financial institutions must assess, contract with and monitor third parties, consultants included, with visibility into subcontractors. The guideline took effect May 1, 2024, and legacy arrangements are updated at renewal, which is when the questionnaire arrives.
PIPEDA applies to the personal information you do hold
Client contacts, interviewees, survey respondents and client employee datasets are personal information handled in commercial activity. The OPC's breach guidance treats your client as remaining in control, and expects contracts with processors to cover breach obligations, hence the notification clocks in your MSAs.
Quebec Law 25 follows Quebec offices and clients
A privacy officer holds the role by default at the highest authority, incidents go in a register kept five years, and a privacy impact assessment is due before personal information leaves Quebec for US-hosted SaaS, which describes nearly every tool a consultancy runs.
Federal contracts bring the Contract Security Program
A Security Requirements Check List on a federal engagement means organization screening, Designated Organization Screening or a Facility Security Clearance, and personnel screening before anyone touches the work.
The CMC code makes exposure a professional matter
CMC-Canada's Code of Professional Conduct bars disclosing confidential client information without specific consent, requires telling the client immediately if it is exposed, and counsels against holding sensitive information you do not need.
Ontario's ESA adds an electronic-monitoring policy
An Ontario employer with 25 or more employees on January 1 must have a written electronic-monitoring policy in place by March 1, and consultancies that monitor laptops and M365 activity are squarely covered.
What goes wrong
How consulting firms actually get burned
The incidents that define this sector share a theme: attackers monetize the client material, and the reputational damage lands on relationships that took a decade to build.
Extortion that publishes client deliverables
Accenture confirmed LockBit stole data in its August 2021 ransomware incident, and Toronto-headquartered Altus Group took back-office systems offline after a June 2021 incident while keeping client products running. The pressure point is always the same: pay, or client files go public.
Email compromise through unprotected admin accounts
Deloitte's global email server was breached through an administrator account that lacked two-step verification, exposing client correspondence. For a firm whose product is advice delivered by email, the inbox is the crown jewels.
File-transfer and third-party tool compromise
Clop's 2023 exploitation of MOVEit reached files connected to PwC and EY engagements, and both firms notified affected clients. A managed file-transfer tool you barely think about can become the breach you must explain to every client on it.
OAuth and SaaS integration abuse
The Salesloft Drift compromise in August 2025 let attackers use a chatbot integration's tokens to export CRM records from Salesforce customers. Every integration bolted onto your CRM or tenant is a door someone else holds a key to.
Misdirection and invoice fraud
A deliverable sent to the wrong client, a dataset attached to the wrong email, or a spoofed partner asking accounts payable to change banking details: low-tech patterns that thrive on utilization pressure and autocomplete.
Client material pasted into generative AI
Copilot and ChatGPT adoption is racing ahead of policy. Professional-body guidance on generative AI, written for lawyers, applies by analogy to any advisor whose inputs are confidential client information retained by the tool.
When organisations call us
The moments an advisory firm picks up the phone
Almost nobody in this sector buys privacy and security work on a quiet Tuesday. A contract, a bid or an incident forces the question, usually with a deadline attached.
A client MSA lands with a security schedule
A bank client's B-10 renewal, or an enterprise client's annual TPRM cycle, turns a handshake relationship into a contract full of audit rights, notification clocks and control requirements someone has to satisfy.
An RFP scores what you don't have
The bid manager finds points awarded for ISO 27001, SOC 2 or CyberSecure Canada, or a federal opportunity carries an SRCL, and the submission deadline does not move for anyone.
A client dictates where the work happens
Being pushed into client-issued VDI, client laptops or a locked data room forces the firm to finally write down how devices, exports and personal machines are supposed to be handled.
Something already went wrong
A consultant's laptop disappears with data-room exports on it, an inbox is compromised, or a vendor in the MOVEit class announces a breach, and the firm discovers its notification duties mid-crisis.
Copilot arrives before the rules do
Associates are already summarizing client documents with generative AI, and a partner realizes there is no policy, no approved tool list and no answer if a client asks.
A deal puts the firm under the microscope
Acquisition by a larger firm or a PE-backed roll-up brings diligence questions about policies, incident history and client-contract exposure that must be answered in a data room, quickly.
Consulting & Advisory Firms: privacy & security questions, answered
Because your clients' regulators make them do it. OSFI's B-10 guideline obliges banks and insurers to manage third-party risk, and enterprise TPRM programs impose the same discipline by policy. You sit in their supply chain, so their obligations become your questionnaire. The practical consequence: your security program is judged by client reviewers on contract renewal timelines, not by a privacy commissioner, and it needs to produce evidence those reviewers accept.
Corporate financials and strategy documents are not personal information, but plenty of what you touch is: client employee datasets in HR and compensation work, survey respondents, interviewees, and your own staff records. PIPEDA covers that handling in commercial activity, Alberta and BC have their own PIPAs, and Quebec's Law 25 adds officer, register and assessment duties when a Quebec office or client is involved. The statutes are real; they are just quieter than your contracts.
CMC-Canada's Code of Professional Conduct adds a professional layer on top of contracts: members must not disclose confidential client information without specific consent, must inform the client immediately if such information is exposed, and are urged not to retain sensitive material they do not need. There is no licensing regulator with discipline powers behind it the way a law society backs lawyers, but a designated consultant who buries an exposure is offside their own profession's code as well as their MSA.
Quebec's Law 25 arrives with the lease. By default the person with the highest authority in the enterprise is the privacy officer until the role is formally delegated, confidentiality incidents must be logged in a register retained for five years, a plain-language privacy policy is expected, and moving personal information outside Quebec, including into ordinary US-hosted SaaS, calls for a privacy impact assessment first. Most consultancies delegate the officer role and stand up the register and PIA process in one project.
Yes, and it should, because answering each client from scratch is what burns partner time. The trick is building once to the strictest plausible requirement set: a control baseline, policies you can attach to MSAs, training records, vendor documentation and an incident plan mapped to notification clauses. From that base, a SIG, a CAIQ, a B-10 review and a bespoke bank questionnaire become lookups rather than projects.
Work backwards from your bid and review calendar. Federal RFP activity concentrates before the March 31 fiscal year-end, so certifications and clearances need to be moving months earlier. Enterprise clients re-assess vendors annually on their own cycles, and B-10-driven reviews tend to land at contract renewal. If a certification or a Designated Organization Screening might be scored in the next bidding season, the preparation belongs in this quarter, not the one when the RFP drops.
