Who Needs FINRA Compliance

FINRA membership is required for any firm that acts as a broker-dealer in the United States, meaning any firm that buys or sells securities on behalf of customers or for its own account. If your firm is registered with the SEC as a broker-dealer, you are a FINRA member and subject to its full rulebook. For background on FINRA itself, see What Is FINRA.

Who Must Be a FINRA Member

Under Section 15(b) of the Securities Exchange Act of 1934, any firm that acts as a broker or dealer in securities must register with the SEC and become a FINRA member (or a member of another SRO, though FINRA is the dominant SRO for broker-dealers).

Firms that must be FINRA members include:

Full-service broker-dealers that execute trades and provide investment advice
Discount broker-dealers and online trading platforms
Clearing and carrying firms that hold customer assets and settle trades
Introducing broker-dealers that bring customer accounts to clearing firms
Market makers that provide liquidity in securities markets
Investment banks that underwrite securities offerings
Dually registered firms that operate as both broker-dealers and investment advisers

Who Is NOT Required to Be a FINRA Member

FINRA membership is specific to broker-dealers. The following are generally NOT required to be FINRA members:

Registered Investment Advisers (RIAs) regulated solely by the SEC or state securities regulators (though if they also operate a broker-dealer, that entity must be registered)
Banks that buy and sell securities in limited circumstances may qualify for exemptions
Insurance companies unless they operate a broker-dealer subsidiary
Hedge funds and private equity funds that do not act as broker-dealers

Registered Representatives

Individual securities professionals (salespeople, traders, analysts, and others who work for FINRA member firms) must be registered with FINRA as “registered representatives.” They must pass qualifying examinations (Series 7, Series 63, etc.), complete continuing education requirements, and are subject to FINRA’s conduct rules personally, not just through their firm.

What Compliance Obligations Apply

Once your firm is a FINRA member, you are subject to:

FINRA’s complete rulebook, including conduct rules, operational rules, and financial rules
SEC regulations that FINRA enforces on the SEC’s behalf
FINRA examination: routine and for-cause examinations of your firm’s practices, records, and controls
Annual reporting: FINRA requires member firms to file various periodic reports, including the annual Form BD amendment
Cybersecurity controls as assessed during examinations, consistent with FINRA’s published cybersecurity guidance

A full breakdown of what these controls look like in practice is in our FINRA compliance checklist.

Consequences of Failing to Meet FINRA’s IT and Cybersecurity Requirements

Cybersecurity and technology controls aren’t a side issue in a FINRA exam. Weak supervision of systems that hold customer data, inadequate written supervisory procedures for cyber risk, and poor vendor oversight are all independently sanctionable, whether or not a breach ever occurs. FINRA’s Sanction Guidelines give examiners a wide range of tools, and enforcement history shows they use them:

Monetary fines ranging from a few thousand dollars for a first, limited violation to tens of millions of dollars for firm-wide supervisory failures. FINRA fined 12 firms a combined $14.4 million in a single sweep over failures to preserve records in a tamper-proof format, and cybersecurity- and supervision-related fines regularly land in the six- and seven-figure range for individual firms.
Regulator-level penalties beyond FINRA. Broker-dealers that mishandle customer data can also face SEC enforcement under Regulation S-P. In 2022, the SEC fined Morgan Stanley Smith Barney $35 million for failing to properly decommission old servers and hard drives, exposing the personal information of roughly 15 million customers.
Mandatory undertakings, such as engaging an independent consultant to review and certify remediation of the underlying control failures, at the firm’s expense and on a public record.
Suspension or bar of registered representatives and supervisors found individually responsible for failing to escalate or address known control gaps.
Heightened supervision status, which increases the frequency and depth of future examinations and can follow a firm for years after the underlying issue is resolved.
Reputational and business harm that outlasts the fine itself: institutional clients and clearing partners increasingly require evidence of a firm’s cybersecurity posture before doing business, and disciplinary history is publicly searchable through FINRA BrokerCheck.

The pattern across these cases is consistent: the underlying failure is rarely a single breach. It’s the absence of a continuously enforced control, whether that’s access management, patch management, vendor oversight, or supervisory review, that examiners can point to well before any incident occurs. See how much FINRA compliance costs for how that compares to the cost of an enforcement action.
