Vendor Security Review & Questionnaire Support for Law Firms
This service works both sides of the questionnaire. We vet the cloud vendors that hold your matter files, practice management, DMS, closing platforms and the MSP itself, against what your law society expects, and we help the firm answer the security questionnaires its own clients send. Firms call us before moving records to a new platform, or when a bank client's review lands and the honest answers are not ready.

What you're protecting
The vendor decisions that carry client files with them
Every SaaS adoption is a custody decision about privileged records. Review effort goes where the sensitivity is, and in a firm that hierarchy is clear.
Practice management and accounting
Platforms in the Clio, CosmoLex, Soluno, LEAP or Actionstep category hold matters, contacts, billing and often trust accounting. Whoever compromises this layer effectively holds the practice.
The document management system
A DMS such as NetDocuments, iManage or SharePoint concentrates the firm's entire written record of privileged work. Its hosting model, access design and export path deserve the deepest scrutiny you apply anywhere.
Closing, filing and payment tools
Real-estate platforms, e-signature, court-filing services and payment processors each touch identity documents, funds flow or both, and each adds a party to your confidentiality picture.
The MSP holding the keys
Your IT provider has administrative reach over everything above. That makes its own security posture, staff vetting and contract terms a first-order review target, not an afterthought.
Regulatory map
Why the due diligence is the lawyer's, not the vendor's
Law societies are explicit that adopting a cloud tool does not delegate the professional obligations that ride on it. The review file we build is your proof the duty was discharged.
The LSBC checklist and Rule 10-3(5)
BC's cloud computing checklist sets out what to examine before records move, and the Law Society can declare an entity not a permitted cloud provider under Rule 10-3(5). Vetting is the difference between a defensible choice and a gamble.
Quebec's Guide des TI
The Barreau's guide places the burden on the lawyer to take reasonable means so cloud-held confidential information cannot be read or intercepted, which presumes an informed look at the vendor before signing.
LSO's technology guideline
Ontario's practice-management guideline on technology frames tool selection as part of competent practice, and a documented vendor assessment is what that looks like on paper.
Accountability that survives outsourcing
PIPEDA keeps the firm answerable for personal information in a processor's hands, so a vendor's breach lands on your notification obligations, your clients and your name.
What goes wrong
Where unvetted vendors hurt law practices
Vendor risk in a firm is concrete: it is the platform holding closings, the transfer tool moving discovery, and the contractor with domain admin.
A provider your regulator would not accept
Choosing a tool that cannot keep records producible, or that fails the criteria your law society publishes, invites hard questions at the next practice review, with your client data already inside.
File-transfer and e-discovery compromise
The 2023 MOVEit campaign showed how one managed file-transfer product exposed client documents across the professional-services world. Small-firm equivalents are the sharing and e-discovery tools bolted onto the DMS.
Foreign reach into hosted records
US-hosted platforms sit within the reach of the US CLOUD Act, a factor the LSBC checklist tells firms to weigh, and one your engagement letters may need to speak to.
An MSP as single point of failure
If the provider's credentials are phished, every system it administers is exposed at once. Contract terms, MFA on administrative access and breach-notice clauses are the mitigations a review verifies.
Our vendor security reviews for law firms
What our review covers, in both directions
One engagement, two deliverable streams: a defensible vendor file for the tools you buy, and credible answers for the clients who scrutinize you.
Vendor due-diligence assessments
Structured reviews of practice-management, DMS, closing, e-signature and transfer vendors covering hosting location, encryption, access, exportability, breach history and termination, mapped to your law society's criteria.
Evidence evaluation
We read the SOC 2 reports, ISO certificates and security documentation vendors provide, translate what they actually attest to, and flag the gaps marketing language papers over.
Contract terms guidance
Recommended clauses for MSP and SaaS agreements: breach notification windows, confidentiality, administrative access controls, data residency, subcontractors, and return or destruction of records on exit.
Client questionnaire support
Gap review against what your clients' questionnaires and OCG security schedules ask, documentation guidance to organize your policies and evidence, and internal review of draft answers before submission.
A reusable review framework
Tiering and templates the administrator can apply to the next tool a partner wants to buy, so diligence becomes routine instead of a crisis each time.
How the engagement runs
How a review engagement runs for your firm
Step 1
Build the vendor map
We list every service touching client records, from the DMS to the e-signature tool, tier them by sensitivity, and pull the contracts and security documentation on file.
Step 2
Assess the critical tier
The platforms holding matters, money and identity documents get full assessments against law society criteria, with vendor follow-ups where the documentation is thin.
Step 3
Report and remediate
Findings arrive as decisions for the partnership: accept, fix the contract, change the configuration or plan an exit, each with its reasoning recorded.
Step 4
Answer the other side
With the vendor file in order, we help complete client questionnaires accurately, attaching evidence and handling follow-up questions from the client's security team.
What it costs
What determines vendor review pricing for firms
Scope drivers are the length of your vendor list, how many sit in the critical tier, whether MSP and SaaS contracts need term-by-term review, and the volume of client questionnaires arriving each year. A boutique with one platform and one MSP is quick to assess; a firm running separate closing, e-discovery and payments tools across offices is not.
Vendor and third-party compliance oversight also comes standing inside the Virtual Privacy Office retainer. We will quote once we have seen your vendor list and a sample questionnaire.
Law Firms: Vendor security reviews questions, answered
Work the checklist as a set of questions the vendor must answer in writing: where data is hosted and replicated, who at the vendor can access it, how it is encrypted, how you retrieve records if the relationship ends, what happens on a breach, and whether the terms let you meet your record-production duties. Then record your conclusions and the documents relied on. The output is a diligence file that shows a reasonable, informed decision, which is exactly what the Law Society framework contemplates.
It can be, but it is a decision to make with open eyes rather than by default. US hosting brings CLOUD Act reach, which the LSBC checklist flags, and BC best practice is to tell clients when their records are stored outside Canada. Several major vendors offer Canadian regions, which simplifies the analysis, and a Quebec office adds Law 25's assessment step for information leaving the province. Our review lays out the options so the partnership chooses deliberately, with client-facing language ready.
The questionnaire is about your firm's controls, and outsourcing their operation does not outsource the answers. We work with the MSP to pull the specifics, which controls are enabled, what is monitored, how backups run, and translate them into responses the firm can honestly sign. Where the MSP cannot evidence something the client requires, that becomes a remediation item with a date, which clients receive far better than a hopeful yes that unravels on audit.
At minimum: confidentiality that covers client information to the standard your conduct rules demand, a defined breach-notification window with a named contact, restrictions and MFA on administrative access, disclosure and flow-down for subcontractors, clarity on where firm data resides, cooperation with your questionnaires and audits, and return or destruction of data with proof at exit. Many firm-MSP relationships run on an invoice and goodwill; a review usually finds the contract is the biggest gap.
Ask for a current SOC 2 report or ISO 27001 certificate where the vendor has one, plus their security overview, data-residency statement, breach-notification commitment and business-continuity summary. Then read them: a SOC 2 scoped to a different product, or a certificate covering only the head office, proves less than the sales deck implies. For smaller legal-tech vendors without certifications, a completed questionnaire and specific contractual commitments can substitute, provided someone qualified evaluates the answers.
