9 Tips for Protecting Consumer Data (& Why It‘s Important to Keep It Secure)

Want to build trust with your customers? Show them that you value their privacy by following these nine tips for protecting consumer data.

In today‘s digital economy, data is a company‘s most valuable asset. Businesses collect a wealth of information on their customers, including personally identifiable information (PII) like:

• Names
• Email addresses
• Phone numbers
• Mailing addresses
• Birthdates
• Social security numbers
• Financial account details

According to IBM, the average company manages over 8,200 customer data sources. Customer data allows businesses to provide personalized experiences, improve their offerings, and make smarter decisions.

However, with great data comes great responsibility. Consumers are more aware than ever of privacy risks and expect companies to handle their data with utmost care. After all, exposed PII can lead to identity theft, fraud, and other distressing consequences for individuals.

As a result, data privacy and protection has become a make-or-break issue for consumer trust and loyalty. 71% of consumers say they would stop doing business with a company if it gave away sensitive data without permission, found a PwC survey.

On the flip side, 76% are more likely to trust companies that go above and beyond the bare minimum when it comes to data protection. Respect for privacy is now the foundation of lasting brand relationships.

So how can your company step up its data protection game and show customers that their privacy is your priority? Follow these nine key tips.

1. Ingrain Data Protection Into Your Company Culture

Data security is not a one-and-done checklist item or the job of a single department. It requires an ongoing, company-wide commitment and shared sense of responsibility.

Make data protection a core company value and weave it into the fabric of your culture, starting with leadership support. Have executives frequently communicate the importance of data privacy through words and actions.

Put clear data usage and protection policies in place, like:

• How consumer data can be collected, accessed and used
• Requirements for strong passwords and authentication
• Protocols for handling data securely when working remotely
• Consequences for violating data privacy rules

Provide engaging, regular training on your data protection practices to all employees, from new hires to the C-suite. Empower them to play an active role in safeguarding customer data every day.

2. Build a Dedicated Data Privacy Team

While everyone should be a data privacy champion, it helps to have subject matter experts leading the charge. Consider creating a core team responsible for:

• Developing and implementing your data protection strategy
• Ensuring compliance with privacy regulations
• Staying on top of the latest security threats and best practices
• Driving privacy awareness and education
• Serving as the go-to resource for data privacy questions

Key roles to include:

• Chief Privacy Officer to oversee the entire program
• Data Protection Officer to ensure compliance with GDPR and other laws
• IT Security Analysts and Engineers to manage technical protections and monitor for breaches
• Privacy Counsel to provide legal guidance

Think of this team as your data Avengers, protecting your customer data and brand from privacy villains.

3. Take a "Less Is More" Approach to Data Collection

The more consumer data you collect, the more you have to protect (and the more damage that can be done if that data is compromised). Practice data minimization by only collecting what you truly need to provide your products or services.

For example, if you‘re an ecommerce company, you likely need customers‘ names, email addresses, payment details and shipping info to process orders. But you probably don‘t need to know their birthdate, income level or social media handles.

Clearly communicate what data you collect and why in your privacy policy. Allow customers to opt out of sharing certain data or access the information you have on them.

When it comes to consumer data, remember: just because you can collect it doesn‘t mean you should. Focus on quality over quantity.

4. Limit Internal Access to Consumer Data

Even within your company, not everyone needs access to all of your customer data. The more people who can view and use that data, the greater the risk of both intentional and accidental misuse.

Restrict data access on a need-to-know basis using role-based permissions. Only allow employees to view and work with the consumer data required for their specific job duties.

For example, your marketing team likely needs access to customer email addresses to send promotional messages. But they shouldn‘t be able to see customers‘ credit card numbers.

Regularly review who has access to what data and adjust permissions as roles change. Immediately revoke access for employees who leave the company. Require strong passwords and two-factor authentication to access all data systems.

The principle of least privilege is your friend when it comes to customer data. grant the minimal level of access needed to get the job done – and not a byte more.

5. Anonymize and Encrypt Consumer Data

Data anonymization and encryption are two powerful tools for protecting consumer privacy:

Anonymization involves removing personally identifiable information from a dataset so that it can‘t be traced back to an individual. Common techniques include:

• Randomization: adding "noise" to a dataset to make it appear random
• Pseudonymization: replacing PII with artificial values
• Aggregation: pooling consumer data together so individuals can‘t be singled out

Use anonymization when you want to derive insights from customer data without exposing sensitive details. For example, you could analyze aggregated location data to understand foot traffic patterns without identifying individuals.

Encryption, on the other hand, uses algorithms to scramble data into an unreadable format that can only be reversed with a decryption key. It‘s like putting your customer data in a virtual vault that only authorized users can access.

Any sensitive data – both in transit and at rest – should be encrypted end-to-end, including:

• Databases
• Emails
• Payment transactions
• Data backups and exports

Use the strongest encryption methods available, like AES-256, and securely manage your decryption keys. That way, even if hackers get their hands on your data, it will be unreadable and useless to them.

6. Implement Robust Cybersecurity Measures

Of course, the best way to protect customer data is to prevent unauthorized access in the first place. That‘s where a multi-layered cybersecurity strategy comes in.

At a minimum, your company should use:

• Firewalls to monitor inbound and outbound network traffic
• Antivirus and anti-malware software to detect and block threats in real-time
• Automated security monitoring tools to identify suspicious activity
• Regular vulnerability scanning and penetration testing to find and fix weaknesses

Think of your cybersecurity program as a castle defending your customer data. You need multiple lines of defense – strong walls, a moat, guard towers – to keep the enemies out.

It‘s also crucial to keep all of your software and systems updated with the latest security patches. Unpatched vulnerabilities are like open doors for hackers to waltz through.

Consider investing in threat intelligence solutions to stay ahead of the constantly evolving threat landscape. The faster you can spot and stop potential attacks, the safer your customer data will be.

7. Secure Remote Work Environments

The rapid shift to remote work during the pandemic created new data security challenges. When employees access customer data outside the office, it opens up more potential attack vectors.

To secure remote work:

• Provide employees with company-issued devices that have been properly configured with security controls. Prohibit working with customer data on personal devices.
• Use a business-grade virtual private network (VPN) to encrypt all internet traffic and shield IP addresses.
• Implement strict device usage policies, like requiring computers to lock after a period of inactivity and banning USB drives.
• Make sure home Wi-Fi networks are password-protected and that passwords are changed regularly.
• Train employees on how to spot phishing attempts and other threats targeting remote workers.

Treat remote security with the same rigor and urgency as you would for an office environment. Your data protection practices need to be remote-work-proof.

8. Vet Vendors and Partners Thoroughly

Your company‘s data privacy is only as strong as your weakest link – and that weak link is often a third-party vendor or partner.

Whenever you share customer data with another company, whether it‘s a cloud storage provider, payment processor, or marketing agency, you‘re putting that data at risk.

You need to make sure your vendors take data protection as seriously as you do (or even more seriously). Don‘t just take their word for it – put them through a rigorous vetting process.

Ask potential vendors to fill out detailed security questionnaires on their data protection practices. Request audit reports, penetration test results, and compliance certifications like ISO 27001 or SOC 2.

Include strong data privacy requirements and the right to audit in your vendor contracts. Make them sign a Data Processing Agreement that clearly defines their security responsibilities.

Monitor your vendors‘ data practices regularly to make sure they‘re meeting your standards. If you discover a vendor is not properly protecting customer data, don‘t hesitate to end the relationship and find a new partner that will.

Remember, if a vendor leaks your customer data, your company is ultimately responsible in the eyes of regulators and consumers.

9. Have an Airtight Data Breach Response Plan

Even with the best data protection practices in place, no company is immune to breaches. The key is to respond quickly and effectively to minimize the damage.

Develop a comprehensive data breach response plan that outlines:

• Your internal breach notification process
• Steps to immediately contain and remediate the breach
• When and how to loop in legal counsel
• How to assess the scope and severity of the breach
• Reporting requirements to regulators and law enforcement
• Customer notification and remediation steps
• Post-breach security improvements to prevent repeat issues

Assign an incident commander (usually your Chief Privacy Officer) to quarterback the process and coordinate efforts across teams.

Regularly practice "breach drills" to make sure everyone knows their role and can spring into action at a moment‘s notice.

When a breach happens, transparency is crucial. Notify impacted customers as soon as possible with:

• A clear description of what happened
• What customer data was accessed
• What you‘re doing to resolve the issue and prevent future breaches
• Steps they can take to protect themselves, like changing passwords or placing a credit freeze

Don‘t sugarcoat the situation or try to cover it up. Customers will lose trust in you fast if they feel you‘re not being fully honest and proactive. Treat a breach like a five-alarm fire – because that‘s effectively what it is for your reputation.

Data Privacy Laws & Regulations to Know

To make matters more complex, there‘s a growing patchwork of data privacy laws around the world that require strict data protection standards, breach reporting, and more. Some of the key regulations to be aware of:

Law	Jurisdiction	Key Requirements	Non-Compliance Penalties
GDPR	European Union	Strict limits on data collection and usage, mandatory breach notification within 72 hours, right to be forgotten	€20 million or 4% of global revenue (whichever is higher)
CCPA / CPRA	California	Right to access and delete personal data, mandatory "Do Not Sell" option	$2,500 per violation (CCPA), $7,500 per intentional violation (CPRA)
HIPAA	United States	Encryption of protected health information, regular risk assessments, employee training	$50,000 per violation, up to $1.5 million per year
PIPEDA	Canada	Limits on data collection, mandatory breach reporting, data access rights	$100,000 per violation

This is just a small sample – many other countries and US states have their own data privacy laws, with more being proposed all the time. It‘s crucial to understand which regulations apply to your company based on where you operate and where your customers reside.

Work with your legal counsel to make sure you‘re fully compliant with all relevant laws. But remember, compliance is the bare minimum. To truly build customer trust, you need to go above and beyond in your data protection practices.
