Cloud and infrastructure security

We’ve gone to great lengths to develop a robust security infrastructure at CloudTalk. Here’s what you need to know.

Data Centers & Physical security

CloudTalk uses highly secure and reliable data centers provided by Amazon AWS and Google Cloud Platform across 9 locations globally with SOC2 Type II and ISO 27001 certifications. They employ multi-level biometrics and other security measures to ensure physical access is only granted to authorized personnel. Full redundancy guarantees data safety in case of a system failure. Additionally, CloudTalk employees do not have physical access to the data centers or any related equipment.

Penetration Testing

CloudTalk regularly conducts independent, 3rd-party penetration testing at least once a year, with no customer data exposed to the security company. The results of the testing help prioritize mitigation and remediation efforts.


CloudTalk uses 256-bit encryption to encrypt all data sent to or from the platform, and their API and application endpoints are exclusively TLS/SSL, which has earned an “A+” rating on Qualys SSL Labs’ tests. The company only employs strong cipher suites and has enabled features such as HSTS and Perfect Forward Secrecy.

What type of data needs to be protected in a call center?

In a call center, various types of data need to be protected to ensure the privacy and security of both customers and the organization. This may include sensitive customer information, such as social security numbers, credit card details, and personal identification data. Additionally, call center agents’ personal data, payment information, and intellectual property must be safeguarded from unauthorized access. To maintain the confidentiality and integrity of this information, call centers must adhere to strict security protocols and regulations, ensuring secure data handling and storage. But this requires good call center management and attention to detail because without that no protocol is able to help

How secure is VoIP and IVR?

Even though VoIP is generally deemed more secure than traditional phone lines, it still carries some VoIP security issues. One such risk is that, if your VoIP system is not configured correctly, hackers may be able to eavesdrop on your calls. Nevertheless, if you utilize call encryption and safe call center software that adheres to all regulations and security standards, you need not worry.

An IVR system refers to an automated call system that permits customers to engage with a company over the phone by entering their responses to pre-recorded queries. These systems are widely recognized as highly secure, given that they do not necessitate any human intervention and usually record all calls.

How secure is encryption?

Encryption refers to the transformation of readable data into an indecipherable format to ensure that only authorized individuals can access the information for example via call center analytics. Typically, encryption is used along with other security measures, like passwords or biometrics, to enhance data security. If the encryption keys are safeguarded, encryption can be an extremely efficient approach to secure data.

Why should I improve my call center security?

Enhancing the security of your call center not only shields your customers’ data from unauthorized access but also reduces the risk of fraud and other forms of cybercrime. Furthermore, by taking measures to enhance security, you can enhance customer satisfaction, and build trust in your brand.

How can work-from-home agents keep their work secure?

To ensure the safety of work data and information, work-from-home call center agents should adopt certain security measures. These include using a secure internet connection (avoiding public networks), generating and maintaining strong passwords, accessing work accounts only from trustworthy devices, and logging out completely from their accounts once they finish working. By adhering to these basic precautions, remote call center agents can safeguard their work-related data and information.

What does risk management involve in a call center?

Risk management in a call center involves identifying, evaluating, and prioritizing potential threats and vulnerabilities, including VoIP vulnerabilities, that could impact the security, confidentiality, or availability of data and information. It also involves developing and implementing strategies to mitigate, monitor, and manage risks associated with VoIP issues, ensuring the call center’s compliance with relevant regulations and standards.
