Mastering Compliance: The Three Lines of Defense

One widely used approach is the Three Lines of Defense (3LoD) model. It helps organizations define responsibilities across different teams, ensuring risks are managed proactively. But how does it actually work? What are the roles of each "line", and how can businesses implement this model efficiently? More importantly, how can Dotfile simplify this process? Let's dive in!

‍

First line of defense: the frontline of risk management

The first line of defense consists of operational teams—the people directly handling business activities and customer interactions. These can be your sales teams, customer support reps, or account managers, who are the first exposed to potential risks.

‍

Their role in risk & compliance

• Following compliance policies in their daily work.
• Identifying and mitigating risks as they arise.
• Reporting anything suspicious to the compliance team.

‍

Example: a relationship manager’s role in KYC

Here, let’s imagine a sales at a bank onboarding a new client, called Client A1 Investment. He’s responsible for conducting KYB checks, verifying documents, and ensuring compliance with anti-money laundering rules.

If something looks off, maybe an address doesn’t match official records or a document seems altered, he needs to escalate the case to the compliance team before proceeding. Or, the processes need a 2nd line verification even if nothing suspicious occurs at the onboarding stage, which is the most common situation in an organization.

‍

Second line of defense: the compliance & risk management team

The second line consists of compliance officers and risk management teams, who oversee the first line and ensure they’re following policies correctly. Their job is to provide guidance, monitor activities, and ensure your organization stays within regulatory requirements.

‍

The role of the second line of defense in risk & compliance

• Create and enforce compliance policies.
• Provide training and support to operational teams.
• Review, monitor processes & conduct risk assessments.
• Handle regulatory reporting and audits.

‍

Example: reviewing a high-risk client

Here let’s say the compliance officer reviews Client A1 Investment brought up by the sales. He will investigate the client’s history, conduct the checks needed according to the internal policies, and determine whether additional verification is needed.

If the risk level is too high, he might decide to reject the onboarding or according to the internal policies ask for a review from his manager/the Head of Compliance or if needed the CEO/Board. If everything is OK, he’ll approve the client while setting up ongoing monitoring checks according to the policies.

‍

Third line of defense: internal audit & independent oversight

The third line of defense is internal audit (also called Q&A), a function designed to assess whether the first two lines are doing their jobs effectively. Auditors provide independent reviews, identify gaps in compliance, and recommend improvements.

‍

The key responsibilities of the third line of defense in compliance

• Conducting periodic audits of compliance processes.
• Identifying weaknesses and inefficiencies.
• Making recommendations to improve risk management and ensure they are done.
• Reporting findings directly to senior management.

‍

Example: auditing the client onboarding process

Here, his colleague Tom, who’s an internal auditor in the company. During his audit work, he’ll review how the onboarding for Client A1 was handled. Were all KYC checks performed correctly? Were any steps skipped or neglected? If Tom finds weaknesses, such as inconsistent risk assessments or documents not asked, the auditor will suggest remediations to prevent future issues and will make sure they are set up properly.

‍

Challenges of the three lines of defense model

While effective, the 3LoD model isn’t without challenges:

• Cost & Complexity: Small companies may struggle with implementation due to limited resources in their compliance teams.
• Regulatory Pressure: Laws and requirements from regulators are constantly evolving, requiring ongoing adjustments.
• Communication Gaps: Poor coordination and visibility issues between teams can weaken risk oversight. You need to be very well organized in your teams to make sure all the lines are effective.
• Manual Processes: Outdated processes make compliance slow and error-prone. We are seeing too many companies with multiple Excel sheets that lead to mistakes or waste of time as the tools used are outdated or not adapted to your needs.

This is where Dotfile comes in!

How Dotfile supports the three line of defense model

Dotfile simplifies compliance by automating your processes and policies, making it easier for your teams to meet your regulatory requirements.

• First Line: Dotfile helps operational teams follow AML procedures easily, instead of relying on manual paperwork, they spend less time on compliance time, and they focus on selling and having the smoothest onboarding journey for your customer.
• Second Line: Compliance teams can seamlessly review applications, assess and set up risk levels, assign roles within the team, and escalate cases, all within a single platform. With built-in communication tools, teams stay aligned. It helps you to do all your screening and AML checks at the time of the onboarding and during the time of the business relationship.
• Third Line: Auditors and risk officers can access a transparent audit trail, making it easy to review past decisions, track compliance efforts, and ensure adherence to policies. It helps you during an internal audit but also during an external audit from regulators. You can in a second access all your cases (onboarding) and share audit trails, documentation, checks, etc. to your regulator.
