2 More Steps Call Centers Can Take To Ensure Online Security

Call center security involves much more than protecting a website or payment portal. Contact centers may handle customer identities, account information, payment data, login credentials, and other sensitive information, making cybersecurity an important part of both customer service and daily operations.

• Protect Customer and Payment Data
• Strengthen Authentication and Access Controls
• Train Agents to Protect Customer Information
• Keep Systems and Software Secure
• Prepare for Security Incidents
• Communicate Clearly With Customers

Organizations may already use encryption, secure payment systems, protected customer portals, firewalls, antivirus or endpoint protection, and regular software updates. These are important security measures, but protecting a modern contact center requires a broader approach that combines technology, people, processes, and continuous monitoring.

Contact center security is not a single technology. It is a combination of secure systems, controlled access, trained employees, documented procedures, and the ability to respond quickly when something goes wrong.

Protect Customer and Payment Data

Organizations should first understand what sensitive information their contact center collects, processes, transmits, or stores.

Depending on the program, this may include:

• Customer names and contact information
• Account numbers and customer identifiers
• Payment card information
• Login credentials
• Financial information
• Healthcare or other sensitive personal information
• Recorded calls and interaction histories

The less sensitive information an organization unnecessarily stores, the less information may be exposed if a security incident occurs.

Contact centers that accept payment cards should also ensure that their payment processes and technology are designed around applicable PCI Security Standards.

Limit Access to Sensitive Information

Employees should have access only to the systems and information required to perform their jobs. Administrative privileges and access to sensitive customer information should be carefully controlled and reviewed.

Role-based access, individual user accounts, authentication controls, activity logging, and appropriate session management can help reduce unnecessary exposure of customer information.

Strengthen Authentication and Access Controls

Password security remains important, but modern security practices should not rely on passwords alone.

Organizations should encourage strong, unique passwords and use multi-factor authentication (MFA) where appropriate, particularly for administrative accounts, remote access, sensitive systems, and other higher-risk access.

Current security guidance does not support forcing users to change passwords simply because a fixed number of days has passed. Password changes should instead be required when there is evidence that a credential may have been compromised.

The objective is not to make passwords harder for users to remember. It is to make unauthorized access significantly harder for attackers.

Organizations should also have procedures for quickly disabling accounts when employees leave the company or no longer require access to a particular system.

Train Agents to Protect Customer Information

Technology alone cannot protect a contact center. Agents and supervisors interact with customer information every day, making employee awareness an important part of the security program.

Security training should help agents recognize and respond appropriately to situations such as:

• Phishing emails and suspicious links
• Requests for passwords or authentication codes
• Social engineering attempts
• Unusual customer verification requests
• Unauthorized attempts to access account information
• Suspicious files or software
• Potential disclosure of customer information
• Lost or compromised credentials

Experienced call center agents should understand not only how to provide good customer service, but also how to protect the information customers entrust to the organization.

Customer Verification Matters

Agents should follow established authentication procedures before providing sensitive account information or making important changes to a customer's account.

Attackers may attempt to manipulate customer service representatives into resetting passwords, changing contact information, revealing account details, or bypassing normal verification procedures.

Clear procedures and escalation paths can help agents handle unusual situations without improvising security decisions during a customer interaction.

Keep Systems and Software Secure

Contact centers rely on multiple technologies, including CRM platforms, communications systems, workforce management tools, operating systems, web applications, customer portals, and third-party integrations.

These systems should be actively maintained. Organizations should monitor security advisories, evaluate vulnerabilities, install appropriate security updates, and replace unsupported software when necessary.

Security teams should also understand which third-party services have access to customer information and ensure that those relationships are included in the organization's security and vendor-management processes.

A contact center is only as secure as the systems, integrations, employees, and third parties that have access to its information.

Prepare for Security Incidents

Even organizations with strong preventive controls need to prepare for the possibility of a cybersecurity incident.

A documented incident response plan should define what happens when suspicious activity, unauthorized access, malware, exposed information, or another security problem is discovered.

The plan should identify responsibilities for areas such as:

• Technical investigation and containment
• Preserving relevant evidence and logs
• Management escalation
• Legal and compliance review
• Customer and employee communications
• Notification requirements
• Credential resets when appropriate
• Recovery and restoration of affected systems
• Post-incident review and corrective action

Organizations can review the Cybersecurity and Infrastructure Security Agency's incident response resources when developing or reviewing their procedures.

Communicate Clearly With Customers

When a security incident affects customer information, communication can become an important part of the response.

Organizations should have procedures for determining what happened, what information may have been affected, which customers may be impacted, and what notifications are required under applicable laws and contractual obligations.

When customers need to take action, communications should clearly explain the appropriate steps. Depending on the incident, this could include changing a compromised password, monitoring an account, contacting a financial institution, or taking another specific protective measure.

A security notification should give customers useful information they can act on, rather than simply informing them that an incident occurred.

Organizations can also review the Federal Trade Commission's Data Breach Response Guide for Business when developing incident communication procedures.

Security Is Part of the Customer Experience

Customers expect organizations to protect their information while still providing convenient service. Security measures should therefore be incorporated into the broader customer service strategy.

The objective is to create processes that protect customers without unnecessarily complicating legitimate interactions.

Strong security requires coordination between information technology, compliance, management, operations, and the agents communicating directly with customers.

For organizations using a nearshore contact center, the same security policies, access controls, training standards, technology requirements, and incident response procedures should extend to every team handling customer information.
