When adopting any new technology, it\u2019s only natural to have concerns about security, and moving to a hosted phone system is no different. If you\u2019re used to your traditional phone system, you may have doubts about how secure a phone system and storing data in the cloud is. That\u2019s why we answer the most frequently asked questions about hosted phone system security here.<\/p>\n\n\n\n
Is my data secure in the cloud?<\/h3>\n\n\n\n
You may be concerned about storing communication data in the cloud. However, local systems or telephone systems are also susceptible to attacks, or can be destroyed in the event of incidents in the company. All data is often lost in the process.<\/p>\n\n\n\n
This doesn\u2019t happen with a hosted telephone system: your data is secure in the cloud, encrypted and protected from unauthorized access. Reliable providers also store it in several geographical locations, for greater reliability in the event of an emergency.<\/p>\n\n\n\n
Are hosted phone systems more vulnerable to security breaches?<\/h3>\n\n\n\n
Hosted phone systems and traditional phone systems carry the same risks in terms of security breaches. A hosted phone system is no more vulnerable than a traditional phone system and could even be described as more secure, as cloud technology means your data is kept securely off-site and encrypted, making it harder for attackers to get at it. Whether it\u2019s denial of service attacks, call interception or malware attacks, your data is protected by security measures such as continuous network monitoring, 2-factor authentication, encryption, firewalls, virus protection and more.<\/p>\n\n\n\n
Does the cloud offer additional security?<\/h3>\n\n\n\n
Cloud phone system providers are investing in innovative new security measures that they can pass on to their customers. So hosting your phone system in the cloud can give you an extra layer of security that a traditional phone system cannot. You can also rest assured that your data will not be lost if it is stored securely in the cloud. Should you need access or lose something on your end, you can access it quickly in the cloud. To give you peace of mind, reliable VoIP providers offer security from any threats so that your customer data is protected from attack, which also helps to build trust between you and your customers.<\/p>\n\n\n\n
How can I keep my phone system secure?<\/h3>\n\n\n\n
Hosted phone service providers offer you numerous ways to customize data protection in your phone system to ensure optimal security if you want to increase the security of your system. You can maintain privacy and customize it to your company\u2019s needs by controlling your caller ID. When you make outbound calls, you can prevent the recipients of the calls from seeing where they are coming from (to prevent nuisance calls or scams from entering your business that could compromise your system).<\/p>\n\n\n\n
You can also set up call screening to prevent dangerous fraud calls from entering your business and to protect your employees from exposing their data to attackers. Hosted phone service providers protect your business data by implementing robust security measures at all levels, namely network, physical, host, application and data, so that you are always protected from security threats.<\/p>\n\n\n\n
Will my hosted phone system comply with security regulations?<\/h3>\n\n\n\n
The reliable providers offer multi-level security measures to secure inbound and outbound calls, giving you further protection against dangerous fraud calls. Cloud telephony takes the burden of compliance off your business and ensures your phone system is fully compliant. Providers that meet the highest standards store customer data in the cloud, adhering to all regulations to ensure the most secure business communications.<\/p>\n\n\n\n
Conclusion<\/h3>\n\n\n\n
Hosted phone systems are very secure and can even provide additional security compared to traditional phone systems. In the event of an attack, you can rest assured that your hosted phone system provider has procedures and processes in place to ensure that your data is safe in the cloud.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Frequently asked questions about hosted phone systems<\/h3>\n\n\n\n
What is a hosted phone system?<\/strong>
A hosted phone system is a phone system that does not sit on company premises but is operated by the provider in the cloud. Calls run over the internet, and the provider handles maintenance and updates. Common alternative terms are cloud phone system, hosted PBX and cloud telephony.<\/p> <\/div>
How does a hosted phone system differ from an on-premises system?<\/strong>
The difference lies in where it runs and who carries the responsibility. With an on-premises system, the company owns the hardware, the maintenance and the outage risk. With a hosted system both sit with the provider, but operations depend on the internet connection.<\/p> <\/div>
What happens during an internet outage?<\/strong>
If connectivity fails, cloud telephony is affected too. A hosted phone system therefore needs a redundancy concept, such as a second line or a mobile backup per site, plus call forwarding to mobile numbers as a fallback.<\/p> <\/div>
How important is the internet connection for voice quality?<\/strong>
Very important. Voice is sensitive to latency, jitter and packet loss. A hosted phone system is only as good as the connectivity beneath it, which is why line quality and prioritisation of voice traffic belong in the planning.<\/p> <\/div>
Where is the data of a hosted phone system stored?<\/strong>
That depends on the provider. Reliable providers store data encrypted and across several geographical locations. Companies with requirements on the storage location should ask specifically about data centre locations and data processing terms before signing.<\/p> <\/div>
How does SAVECALL help with the selection?<\/strong>
SAVECALL compares cloud telephony providers vendor-neutrally and also assesses the connectivity per site. The result is a solution that fits the existing infrastructure, rather than a platform placed on a network that cannot carry it.<\/p> <\/div> <\/div>\n\n\n\n
