Is VoIP Secure?

In today’s time, remote working has gained a lot of importance. Though remote working has so many advantages, it comes with few concerns as well. The most important concern of enterprises is the security of their data. As everyone is working remotely from different places, it becomes quite difficult to protect the important data and information of the company. Whether it’s a small business or a large enterprise, keeping communication secure is the top priority of every business owner. To lower the risk of cyber-attacks and protect important data, many businesses are moving towards VoIP services. With the growing awareness about VoIP services, the VoIP market has reached new heights. It is expected to grow even more in the coming years. According to a report (by Business Wire, 2020), the size of the VoIP market is predicted to reach $183.7 billion by 2027. The worldwide VoIP phone system market share is projected to rise at a CAGR of 3.1% between 2019 and 2024 (Global Info Research, 2019). Besides, the mobile VOIP users are expected to reach 3 billion by 2021 (WisdomPlexus, 2019).

However, many businesses are still confused about whether VoIP is secure enough to protect the communication system of an organization. With the help of the right VoIP security strategies, the risk of cyber-attacks and various other threats can be controlled to a great extent. Let’s have a look at the VoIP system in detail to have a clear picture of this system:

How is VoIP Different from Traditional Phones?

VoIP or Voice over Internet Protocol phones is quite different from traditional landline phones because calls are made. In VoIP, calls are placed over the Internet. On the other hand, traditional landline phone calls are made over the Public Switched Telephone Network (PSTN). 

Now let’s have a look at the working system of VoIP and traditional phones.  

Working System of VoIP Phones

VoIP phones convert analog voice signals into various separate digital data packets. These data packets are transferred over the Internet and directed towards their destination. The destination is the other end of the phone line. No matter what device the users are using to make or receive the calls, the key thing that connects, maintains, and terminates the VoIP phone calls is the SIP (Session Initiation Protocol). Moreover, IP phones are generally sent over private voice networks. 

Working System of Traditional Phones

The landlines, also known as analog phone systems, send voice signals via copper wiring and fiber optic cables of the Plain Old Telephone Service (POTS). These systems make use of circuit switching to connect phone call endpoints. Landlines require a physical connection to operate. By hacking into the POTS wiring, anyone can access the ongoing conversations and listen to the calls. 

Which System is Secure? Traditional or VoIP Phone System?

It is important to note that both the traditional and VoIP systems are not completely free from the chances of hacking and other security threats. However, with VoIP systems, businesses get many options to secure their business phone system compared to traditional telephony systems. 

To make VoIP secure for calling, the users can utilize the same or similar security tools to protect their Internet, digital personal data, and cloud storage devices. While using VoIP, it is vital to take all the precautionary measures and risk assessments to prevent various VoIP security attacks such as phishing, call hijacking, call tampering, malware and viruses, eavesdropping, Denial of Service (DoS), ID spoofing, man-in-the-middle attacks, audio spam, etc. 

Advantages of VoIP over Traditional Phone Service

Below mentioned are some of the key advantages of VoIP over the traditional phone system, have a look:

  • Cost-Effectiveness: Every business, whether big or small, looks for cost-saving opportunities. VoIP system is one such way that can help businesses in making significant cost savings. If we compare the cost, a landline phone system (POTS) costs around $50 per line (for local and domestic calls) each month. In contrast, VoIP plans are usually available for less than $20 per line. This way, VoIP can help businesses to lower their phone bill greatly. 
  • Enhanced Accessibility: With the help of a cloud-based VoIP service, calls can be made from anywhere. It is a great benefit for the mobile workforce. The employees are no longer required to be present physically at the office. Users need to have a good data connection to make and receive calls. If someone is not available to answer the calls, the calls can be directed to another person or the voicemail system. With just a softphone app, businesses can take their business phone with them anywhere. This flexibility and remote accessibility allow a mobile workforce to stay productive and efficient regardless of their location. 
  • Easy Portability: Do you know that a VoIP number or virtual number is entirely portable? Yes, the users can use the same number wherever they go. Thus businesses that are changing their address for some reason can retain the same VoIP number without worrying about losing an important connection. 
  • Scalability: Growing businesses are looking for a scalable solution that can be adjusted based on the growth of the business. A VoIP phone system is one such solution that can be scaled easily based on the growth of the business. The system can be scaled without the need to use any separate dedicated line or expensive hardware. 
  • Advanced features: A VoIP phone system comes with various advanced features that are hard to find in traditional phone systems. It includes call transfer, call recording, auto-attendant, voice/video conferencing, and many others. 
  • Supports multitasking: Apart from making and receiving calls, a VoIP system supports various tasks such as sending files, documents, images, and videos while handling an ongoing call. 

Best Practices for VoIP Security

Some of the best practices that one must employ to ensure utmost VoIP security include:

  • Perform frequent security assessments (in-house and third-party assessments) to inspect VoIP gateways, carry out application-based security scans, etc.
  • White-list and black-list phone numbers. White-listing will allow users to choose certain numbers that can contact them while blocking all others. On the other hand, the black-list helps users block certain suspicious numbers, spam callers, and other unwanted callers. 
  • Implement a strong password strategy. The strategy can include changing passwords every two weeks, avoiding using the same password for multiple accounts, Using uppercase, lowercase letters, special characters in passwords, restricting password reuse, etc. 
  • Avoid Using Public WiFi as it increases the chances of hacking and other wrong practices. 
  • Encrypt business communications so that even if a hacker intercepts it, they won’t decipher it.

Conclusion:

Looking at all the information mentioned above, it is clear that the VoIP phone system is quite better and more secure than traditional phone systems. Businesses must utilize this system to enhance their communication while protecting all their important data and information. However, to enjoy the full benefits, it is advisable to choose a professional VoIP service provider that prioritizes secure communications.
