Reasons Why Encrypted VoIP Phone Systems are More Secure Than Traditional Landlines

The business environment of today looks very different from what it did a few decades ago. With the advent of Internet-enabled communications technology, companies have seen new ways of doing business. Telephone service is one of the aspects of communications that the internet has transformed.

With many organizations shifting to remote work in today’s time, security has been the utmost concern of enterprises. Since employees are working from different geographic locations, monitoring all their activities can be far-fetched.

On such occasions, protecting important data and information has been a complex task to achieve. In fact, enterprise data security remains the top priority for every organization, no matter what work culture they follow.

It is the top priority of every business owner to keep communication secure, regardless of the size of their organization. A growing number of businesses are utilizing VoIP services to lower the risk of cyber-attacks and protect sensitive data. As VoIP services have gained greater awareness, the VoIP market is experiencing new heights, and the growth is expected to be even greater in the upcoming years.

Of course, you will have several questions if you are considering switching landline phone systems with VoIP phone systems. That’s plausible because the type of service you choose for your business can substantially impact how your business communicates.

It also determines the customer experience when they reach out to your business. This article will provide you the key insights on why VoIP is a worthy alternative to landlines.

Comparing VoIP phone system with Traditional landline phone system

In simple words, VoIP is a technology that uses an internet connection for making calls. According to the research, over 60% of organizations with landline telephones migrate to VoIP telephone systems when their landline telephone contracts end.

Similarly, a report by Business Wire suggests that the VoIP market is forecasted to reach approximately $183.7 billion by 2027.

The best way to compare VoIP and landline phone systems is to consider their features. Below is a table that lists some of the top VoIP features that favor VoIP phone systems over traditional landline phones.

VoIP: What are the risks?

Though the benefits of VoIP over traditional landlines are immense, VoIP can be vulnerable to different types of attacks. In VoIP technology, the voice data is converted into tiny packets of digital information that are transmitted over the internet through your home connection.

Therefore, its security depends on the security measures your provider has in place. Here are some of the scenarios where VoIP can be a risk.

1. Cyberattacks

It is possible for hackers to access any online data transmission. You may be more vulnerable to hackers if your VoIP provider doesn’t have robust security measures in place. An attacker can listen in on a confidential conversation in real-time and intercept calls.

Similarly, they can also steal older phone calls recorded and archived for business use. Cybercriminals can also hack into your phone system and install ransomware or spyware on your computer by connecting through the phone system.

On the other hand, you can also suffer network damage from DDoS attacks. Hackers can attack your servers and overwhelm the system with millions of requests. Consequently, your servers go down because they cannot handle the load, possibly bringing your business to an end.

2. Government surveillance

VoIP providers, similar to landline phone providers, are subject to allow access to law enforcement to listen to phone conversations. If an appropriate warrant is obtained, law enforcement may conduct electronic surveillance in accordance with these regulations.

While VoIP can be vulnerable to interception, you have numerous options as far as VoIP security is concerned. Luckily, some VoIP service providers, like KrispCall, incorporate features like end-to-end encryption of voice data. You just need to make your move carefully.

How encrypted VoIP phone systems excel in terms of security?

As mentioned earlier, VoIP incorporates an end-to-end encryption feature, which means encrypted VoIP makes your system much more secure than the traditional landline phone. Let’s have a detailed look at how you can have a better tool to protect it.

1. Encryption

Having your business phone system encrypted means it is your innate immune system against any unauthorized use. With encrypted VoIP, hackers cannot intercept your confidential data in the first place. Even if they do, they can never understand what you are saying.

It means your privacy and security go hand in hand with an encrypted VoIP system.  Additionally, all calls are encrypted between both ends so that no one can find out extra information about the callers, such as their names or locations.

2. Multi-factor authentication

Multi-factor authentication is a reliable way to increase your security. The authentication system enhances your security by forcing users to go through two forms of identification in order to log in to the system.

VoIP systems already need the login credentials of each user that enable them to connect through business telephone. The introduction of multi-factor authentication further creates a layer of security, making it more difficult for unauthorized users to access networks or databases.

3. Calls and access log monitoring

Although call logs are helpful for sales purposes, it’s also helpful for various other reasons. With these logs, you can easily see whether your VoIP phone system has been hacked. Monitoring your call logs regularly gives you a sense of what “normal” looks like. It is possible to detect any anomalies before your call limits are triggered – even before a hack is detected.

Likewise, an access log will show who has accessed your VoIP system. You’ll spot an intruder if you notice an unusual IP address or see that your administrator signed in at an unusual time.

4. Protection against social engineering attacks

Social engineering attacks involve human interaction (social skills) to gain information about a computer system or an organization.

Attackers may appear innocent and respectable, offering credentials to support their claim to be an employee, repair person, or researcher. A strong VoIP provider has a good security practices and a plan of action for such situating ions. All you need to do is choose the right provider.

5. Segregation of network into VLANs

A physical network can be divided into a number of separate virtual networks creating another layer of security for business enterprises. Using a separate network, you can restrict all VoIP traffic.

The use of VLANs can also improve troubleshooting. If any day your phones are not working, you know instantly which network to examine. This means you won’t have to waste time checking routers and other infrastructure.

6. Use Virtual Private Network

VPNs are a very common feature of computer networks in companies. VoIP VPNs are secure and encrypted tunnels built over the internet that send VOIP traffic to and from the internet.

By using a VPN to encrypt your internet connection, you will be able to keep your VoIP conversations safe against unauthorized parties such as hackers and others who monitor your online activity. Further, having your traffic encrypted will protect you from mass surveillance and analysis by commercial organizations and governments.

Conclusion

VoIP is a more reliable and modern way to make and receive calls than the traditional phone system. But you need to use extra security measures when you store everything in the cloud. In the meantime, adding security is often a costly proposition. Of course, encryption increases your security but also takes up more network bandwidth.
