How VoIP Security Protects SMEs From Cyber Threats

Every business needs a solid communication system and for small-to-medium-size enterprises (SMEs) it’s a non-negotiable. It plays a role in their survival, offering a way to stay connected to clients and suppliers while working together internally.

To achieve this, a lot of SMEs have adopted Voice over Internet Protocol (VoIP). Aside from voice and video calling, it’s packed with features that make communication efforts run seamlessly. It’s also much more affordable than traditional phone lines, something which SMEs would certainly appreciate.

However, this digital convenience comes with its own set of risks. Once your communication moves online, cyber threats become a very real and prominent issue. Fortunately, VoIP security is playing a role in keeping SMEs safe online.

What Cyber Threats Do SMEs Face?

Cyber threats come in many forms and SMEs are not exempt from any of them. From eavesdropping to malware, knowing what to look out for can protect you and your business.

Eavesdropping: Hackers are able to listen in on conversations once they have intercepted them. From there, they can access private information like client details and payment passwords.

Phishing: This is one of the more common cyber threats. Hackers impersonate people or companies that employees are familiar with in order to get them to hand over confidential information.

Denial-of-Service (DoS) Attacks: Your VoIP system is overloaded with traffic to disrupt calls and communication channels.

Malware: VoIP is connected to devices which means hackers can access them to plant different forms of malware including viruses, worms or trojans.

How Does VoIP Security Protect SMEs?

Even the smallest data breach can have major consequences for SMEs. Having VoIP security in place right from the start can go a long way in reducing the likelihood of encountering any cyber threats down the line.

Data And Calls Are Encrypted

Just as website data is encrypted with HTTPS, VoIP uses Secure Real-Time Transport Protocol (SRTP) which jumbles up the voice and video data.

If a hacker intercepts the call, they wouldn’t be able to make sense of it unless they had a decryption key.

Firewalls And Session Border Controllers

Firewalls are also used in VoIP setups, specifically to monitor traffic with the goal of stopping unauthorised access.

Similarly, Session Border Controllers (SBCs) inspect voice traffic and if malicious activity is detected, it’s blocked before it reaches your device.

Authentication And Access Controls

VoIP security doesn’t just protect calls, but also the accounts associated with those calls. Most setups will come with Two-Factor Authentication (2FA) and strong passwords with role-based access.

This ensures that only the necessary people can access accounts and hackers can’t use your VoIP for fraudulent calls.

Monitoring For Threat Detection

Nowadays, advanced VoIP security includes real-time monitoring almost like antivirus software. Any suspicious activity, whether it be unusual call patterns or repeated login attempts, will be flagged.

Some VoIP systems even use AI for this monitoring which can stop attack attempts before they cause serious harm.

Regular Updates

If VoIP systems aren’t regularly updated, they are more susceptible to vulnerabilities just like any other software.

However, service providers are constantly releasing new updates with security patches which means SMEs can benefit from up-to-date security without needing a dedicated IT team.

Enables Secure Remote Work

A lot of SMEs either have a hybrid or fully remote team to save on rental expenses. With VoIP security, employees can connect to the Internet safely from wherever they are, especially if they combine it with a Virtual Private Network (VPN).

How To Choose The Right VoIP Security Setup

For SMEs, choosing the right VoIP provider is an incredibly important decision to make. Before you commit to one, make sure to thoroughly research the security features that it offers.

Those who offer end-to-end encryption, multi-factor authentication, AI-based threat detection and regular security patches are more likely to give you and your business the best protection.

Remember, your VoIP system shouldn’t just be for calling, it should be a fully secure means for you to communicate both inside and outside of your company.
