Encrypt VoIP traffic with VPN

Encrypt VoIPIn today’s digital age, the barriers that once kept entrepreneurs from competing with multinational companies have all but vanished. Long gone are the days where first-class resources were only available to blue-chip multinationals. In the 21st century any entrepreneur with a strong vision, ambition and the determination to realize their goals can compete and grow their enterprise by means of the internet. Financing for resources is possible by crowd-funding, infrastructure can be outsourced to cloud service providers, data and information can be gained without leaving your home, and secure communication over the internet can be provided by a VPN service such as CactusVPN.

Of course, communication is very important to every entrepreneur. Whether you are just starting out or are already established, security is always an issue. One must be very vigilant in these times of data piracy and government snooping. With data theft seemingly on the rise, the news headlines are seemingly flooded with tales of credit card and personal user data theft, and viruses and malware affecting the reputations of even the largest, tightly-secured businesses. However, there is one means of communication that requires security, yet there is remarkably little information about the risks involved. We’re talking about using VoIP when engaging in conference calls.

The truth is that unless you take appropriate measures to secure your voice traffic, your data is at risk. That goes for both mobile communication and when you are sitting at a desk. Not every business can afford to have an office where their suppliers or customers are located, and so conference calls are a necessity. Every time you open an unsecured channel, you run the risk of a breach or attack. The same privacy and authentication issues (e.g. passwords) that face data transmission hold true for voice traffic.

Eavesdropping is also a risk that you face whenever you engage a conference call. Hackers can data-sniffing and use other tools to recognize, change, store and play the VoIP traffic traveling over an unsecured network. By isolating the traffic on a single VPN server can mitigate the risk.

We recommend that you encrypt your voice services every time you engage a conference call. The easiest way to do that is to make sure that both you and the party on the other end of the call uses the same servers. In such cases the best way to go about this is if both parties use the same VPN. This ensures that the voice and any data transmissions during the call (presentations, zip files) travel over the same servers.

Ensuring that your voice traffic is secure using a VPN also doesn’t involve any more configuration effort than setting up your network access. There is no need to lease lines from telco’s or have dedicated dial-up facilities. Many entrepreneurs tend to overlook this aspect and thus not only put themselves at risk but also the party on the other end. Merely relying on your ISP or standard antivirus software is naive at best and presents an opening for malicious attack at worst. Ultimately, using VPN to encrypt your VoIP traffic adds an effective layer of security for your enterprise, and as business expenses go, it’s very cost effective. More threats to your enterprise are appearing every day and a VPN can help you to keep both data and voice traffic secure.
