Compliance Checklist

Step 1: Identify Your Obligations

• [ ] List every type of personal data your business collects, stores, or processes
• [ ] Determine which regulations apply based on your industry, location, customer base, and business relationships
• [ ] Document the specific requirements of each applicable regulation
• [ ] Identify any contractual privacy obligations from customers or partners

Step 2: Stay Current on Changes

• [ ] Subscribe to regulatory update notifications from relevant government websites (.gov sites for federal rules, state attorney general offices for state laws)
• [ ] Assign at least two people in your organization to receive these updates (backup coverage)
• [ ] Review regulatory changes quarterly and assess impact on your business
• [ ] Join industry groups or associations that track compliance changes

Step 3: Conduct Annual Security Reviews

• [ ] Audit your technical controls (firewalls, encryption, access controls, monitoring)
• [ ] Review all new systems, software, and cloud services added in the past year
• [ ] Assess whether new devices (phones, IoT, remote work equipment) are covered by your security policies
• [ ] Verify that departing employees have had access revoked
• [ ] Test backup and recovery procedures

Step 4: Review Policies and Procedures

• [ ] Update written security policies at least annually
• [ ] Ensure policies address all current regulatory requirements
• [ ] Review incident response procedures
• [ ] Update data retention and disposal policies
• [ ] Verify that privacy notices on your website accurately reflect your practices

Step 5: Prepare for New Regulations Proactively

When a new privacy law is announced (even before it takes effect):
- [ ] Assess the gap between your current practices and the new requirements
- [ ] Update technical controls (encryption, access management, data handling)
- [ ] Revise administrative procedures (policies, training, documentation)
- [ ] Review physical security measures (facility access, device security)
- [ ] Budget for any necessary changes

Step 6: Train Your Employees

• [ ] Provide privacy and compliance training during onboarding
• [ ] Conduct refresher training at least annually and whenever regulations change
• [ ] Tailor training to job roles (people handling customer data need different training than those who don’t)
• [ ] Document all training: who attended, what was covered, when it occurred, and test results
• [ ] Keep training records for at least the retention period required by your applicable regulations

Practical Tips

Start with what you collect. You can’t protect data you don’t know you have. Map your data flows: what comes in, where it’s stored, who has access, and where it goes.

Minimize what you keep. The less personal data you store, the less you need to protect and the lower your risk in a breach. Only collect what you actually need, and delete it when you no longer need it.

Document everything. If a breach occurs, regulators will ask what controls you had in place and whether you followed them. Documentation is your evidence of compliance.

Don’t wait for enforcement. Getting compliant after a breach or regulatory inquiry is far more expensive and disruptive than doing it proactively.

Get professional help when needed. Privacy compliance can be complex, especially when multiple regulations apply. A qualified privacy consultant or attorney can save you from costly mistakes.
