Practical guide

Vendor due diligence

A starting point for evaluating a new provider or renewing an existing relationship.
All guides

Start with the service, not a score

Define the business purpose, information involved, critical dependencies and consequences of disruption. Scale the review to those risks and your firm's requirements. Record gaps, owners, follow-up dates and the reasons for your decision.

This is general educational guidance, not legal advice, certification or proof of SEC, FINRA or CFTC compliance. Completing this guide does not establish that a vendor or your firm meets regulatory obligations. Consult your legal, compliance, security and risk teams about applicable requirements.

Separate claims from evidence

Vendor claim
A provider's statement. Attribute it, link to the public source where available and note the date. Do not call it independently verified.
Verified fact
A specific assertion checked against suitable evidence. Record source, scope, reviewer and date. One verified fact does not verify the vendor as a whole.
Not verified
Evidence is missing, outdated, ambiguous or outside scope. State the gap without inferring approval, failure or misconduct.

These labels are for your assessment, not new verification badges on ComplianceTechTalk profiles. Keep attributed peer opinions separate from factual assertions.

Review area 1

Ownership and continuity

  • Confirm the legal contracting entity, operating brand and parent company. Do the agreement, invoices and support terms identify consistent responsibilities?
  • Ask how acquisitions, rebrands and product migrations affect existing contracts, support and access to records. Distinguish an announced transaction from a completed one.
  • Identify critical subcontractors and dependencies. What transition arrangements apply if ownership changes or the product is retired?
Suitable for public discussion
Dated official announcements and registry records, with links and clear scope.
Keep confidential
Signed agreements, nonpublic ownership records and named escalation contacts.
Follow-up signals
Unexplained entity differences, unclear responsibility for legacy products or no documented exit path.

Review area 2

Financial stability

  • Review financial evidence proportionate to the service's importance. For private companies, agree suitable confidentiality terms rather than expecting public financial statements.
  • Discuss how operations are funded and dependence on key customers, investors or lenders. Funding announcements alone do not demonstrate financial resilience.
  • Plan for service interruption: record access, data export, transition assistance, termination rights and any appropriate escrow arrangement.
Suitable for public discussion
Public filings and attributed funding announcements. Absence of adverse news does not establish solvency.
Keep confidential
Nonpublic financial statements, cash-flow information, banking details and internal financial assessments.
Follow-up signals
Material inconsistencies, concentrated dependencies or reluctance to discuss continuity safeguards.

Review area 3

Insurance and contractual protection

  • Discuss appropriate coverage with legal or risk colleagues: cyber, professional liability and general liability may be relevant, but requirements should reflect the service's risks.
  • Check the insured entity, policy dates, limits, deductibles and relevant exclusions, including whether contracted activities and subcontractors are covered.
  • Review renewal notifications, indemnities and liability caps together. A certificate is not the full policy; a policy limit is not guaranteed recovery.
Suitable for public discussion
Attribute public insurance statements as vendor claims unless the specific assertion has been independently checked.
Keep confidential
Insurance certificates, policy wording, claims information and negotiated contract terms.
Follow-up signals
Expired evidence, an incorrect insured entity or exclusions that undermine the intended protection.

Review area 4

Security and operational resilience

  • Map data collected, processing and storage locations, subprocessors and access rights. Ask about encryption, privileged access and support access.
  • Review independent assurance for scope, reporting period, exceptions and remediation—not just a badge. Confirm it covers the product you will use.
  • Evaluate incident notification, backup restoration, recovery objectives and recent recovery exercises against your firm's needs and the contract.
  • For AI-enabled services, ask whether information is retained or used for training, which providers receive it and how access and outputs are controlled.
Suitable for public discussion
Public trust-center information with precise attribution. A security assurance report does not establish your firm's regulatory compliance.
Keep confidential
Audit reports, penetration tests, vulnerabilities, network diagrams, incident records, credentials and client data. Never post these on vendor pages, reviews or community discussions.
Follow-up signals
Unclear data locations, broad access, unresolved material findings or recovery commitments without test evidence.

Review area 5

Policies and service governance

  • Check how privacy, retention, deletion, personnel access, change management and supplier oversight apply to your actual service.
  • Clarify record ownership, export, legal holds, deletion after termination and notification of material changes. Reconcile policies with contractual commitments.
  • Review service levels, escalation paths, accessibility needs and responsibilities shared with your firm. Identify policy owners and review dates.
Suitable for public discussion
Current public privacy and service policies. A published policy does not by itself prove effective implementation.
Keep confidential
Internal procedures, negotiated terms, personnel records and firm-specific control requirements.
Follow-up signals
Conflicting terms, vague deletion promises, missing exit rights or no accountable policy owner.

Review area 6

Reputation and customer experience

  • Seek references from firms with similar workflows and risks. Ask about implementation, support, outages and the ability to leave—not just satisfaction.
  • Review credible reporting and relevant official enforcement or court records. Confirm the legal entity and distinguish allegations, findings and final outcomes.
  • Look for recurring themes in dated peer reviews and disclosed affiliations. Individual experiences are opinions, not verified facts about every customer.
Suitable for public discussion
Source-linked reporting and attributed peer experiences. Do not republish private reference calls or personal contact information.
Keep confidential
Reference-call notes, nonpublic complaints and sensitive legal or incident assessments.
Follow-up signals
Mistaken company identity, unsupported accusations, recurring unresolved service problems or promotional claims presented as independent evidence.

Keep a decision record and revisit it

In your firm's approved, access-controlled workspace, record the service and legal entity reviewed, evidence scope and dates, unresolved questions, mitigations, decision maker and next review date. Do not upload that confidential review file to ComplianceTechTalk.

Reassess after material ownership changes, incidents, changes in data use, service deterioration or renewal. Missing evidence is a reason to follow up, not an automatic finding of noncompliance.

Public vendor pages, reviews and community discussions are not a confidential document repository. Share only information you are authorized to disclose; keep client information, security evidence and private assessments within your firm's approved systems.
