The Security of your Phone System Cloud PBX vs On-Premise

With the rising trend of modern phone systems for business communications, VoIP systems have gained popularity in the world of communications. Voice over Internet Protocol (VoIP) systems have the capability to host sensitive information across various communication channels such as phone calls, conference calls, voicemail, and chat. These channels or lines can either be hosted on the cloud or in an on-premise system. Most of the PBX systems function using an internet connection, therefore, the risks associated with cyber hacks and other attacks also increase. Effective measures should be proactively deployed to avoid the events of security breaches and abuse of important data hosted across VoIP communication lines.  

In this blog, we will be sharing what kinds of security threats are possible with your business phone system whether it is a cloud PBX system or installed in an on-premise setting. However, let us first understand why is the security of your VoIP system important. 

The Security of a Business VoIP Phone System 

The current geopolitical and economic climate, combined with inadequate cybersecurity measures, have made for an ideal environment for hackers to operate in. As incidents of cyber-attacks are being reported across all industries and company sizes, it is not surprising that many organizations are becoming increasingly worried about the security of their data and technological infrastructure. 

Ensuring the safety and protection of any system used for business operations is crucial. It goes beyond simply guarding sensitive company information against unauthorized access and involves preventing disruptions and negative effects on services and resources, which can impede business operations, decrease employee efficiency, and potentially harm the company’s reputation. 

The concerns regarding the security of business communication systems rise significantly when businesses are re-evaluating their communications infrastructure. If your business is also in a similar process but you are unsure about the security of cloud PBX vs on-premise phone system, then read on! 

The Security of a Cloud PBX Phone System 

There are security issues associated with using cloud-based applications, like a hosted PBX, because they rely heavily on internet connectivity. As technology advances, the incentive for hackers to take advantage of these systems also increases. When it comes to the security of Cloud-based VoIP phone systems, IT leaders are most concerned about: 

Telecommunications Fraud 

According to a recent report by Communications Fraud Control Association, 73% of the participants experienced an increase in losses to global fraudulent activities. 

Given that telecom frauds continue to increase and are showing no signs of permanent control, it is no surprise that telecom fraudsters are becoming increasingly proficient in taking advantage of both network providers and consumers. However, it does not stop here. While a hit to your business data may cause you financial losses, service providers also lose the trust of their clients and customers in the process amidst the disruption of call traffic across your phone lines. 

Lack of Accessibility  

While a cloud PBX phone system is associated with no maintenance and troubleshooting benefits, it is also associated with the gradual realization that user companies do not have direct access to measure the call quality and inbound and/or outbound call traffic. In the absence of an on-premise PBX phone system, some companies create an apprehension that the lack of accessibility to traffic analytics may be conflicting with their corporate ownership and compliance policies.  

Adaptability 

When companies are in the process of considering a hosted PBX phone system, the perceived risk is associated with the success of its adaptability among employees. A disruption in accepted and in-practice communication infrastructure may be perceived as an added complexity in the absence of realizing the benefits.  

The Security of an On-Premise PBX Phone System 

Since the major difference between a cloud phone system and an on-site PBX system is where the hardware is hosted, the security concerns of the latter also revolve around the reliability of the hardware. 

Disaster Recovery and Management 

On-premise phone systems are known as Single Points of Failure (SPoF) as they do not have geo-redundant servers to keep the communications lines running even in case of some malfunction or server downtime. This poses a threat to the call quality of the users. 

Single points of failure (SPoF) in VoIP phone systems refer to any component or system that, if it fails, will result in the entire system going down. These are critical components or systems that are necessary for the normal operation of the phone system, and their failure can result in a loss of phone service or other critical functionality. Some examples of single points of failure in a VoIP phone system include: 

Network infrastructure: If the network infrastructure (such as routers, switches, and cables) fails, it can prevent the VoIP phone system from functioning properly. 

Power supply: If the power supply for the VoIP phone system fails, it can cause the entire system to go down. 

Internet connection: If the internet connection goes down, it will prevent the VoIP phone system from communicating with the outside world. 

Server: If the server that the VoIP phone system is running on fails, it can cause the entire system to go down. 

Gateway or Firewall: If the gateway or firewall that connects the VoIP phone system to the public telephone network fails, it can prevent the system from making or receiving calls. 

In-House System Update 

It is essential to consistently improve and update the security of your on-premise PBX phone system. Your team is responsible for ensuring that it is secure through the end of life. The more work that needs to be done to optimize it, the more financial resources will need to be allocated to maintain it. 

Secure Scalability 

Secure scalability refers to the ability of an on-premise PBX phone system to expand and adapt to changing business needs while maintaining a prominent level of security. This means that as the company grows, the phone system can accommodate more users and features, while still keeping the company’s sensitive data and communications secure. However, with telecom frauds getting spot-on, manually scaling the on-premise system can leave windows for attackers to penetrate through.  

To mitigate the security risks associated with manual scaling, it could be a good option to evaluate and implement a disaster recovery or continuity plan in case something happens that affects the phone system. This way the organization can have a backup plan and a clear course of action to minimize the impact on the phone system.
