A white paper reveals that ZTNA technology is better suited than VPN to meet teleworking challenges
Systancia and IDC, have published a white paper comparing VPN and zero-trust (ZTNA) technologies to secure the data of companies dealing with with the spread of teleworking and guarantee their business continuity.
This study is based on a global survey conducted by IDC in April 2020, "COVID-19 Impact on IT Spending Survey". This study revealed that 47% of the organizations surveyed believed there would be an increase in demand for secure remote access linked to COVID-19 and the need for new technology and changes to their organization's working model.
Another IDC European survey which examined spending in Europe - "Impact of COVID-19 on the European ICT Market and Ecosystem" (March 2020) - showed that collaboration technologies (+57%) and security (+16%) were the top two IT areas where organizations expected to see growth in 2020.
VPN not suitable for mass teleworking
According to the White Paper produced for Systancia, VPN solutions are not suitable for large-scale teleworking. During the lockdown, many employees had to work from home and many had to use their personal computers. Many companies have been deploying VPNs on their employees' devices. Since these are not secure - or "trusted", opening a VPN connection from an untrusted device can jeopardize the data on the corporate network.
Extending the VPN access to the entire workforce has also led to additional costs, performance and device compatibility issues. Moreover, with a VPN, the audit and monitoring - to understand who has access to what - is not possible and represents an identity and access management issue.
ZTNA, the only coordinated approach of people, processes and technologies
With the ZTNA, it becomes possible to verify the identity of users and characterize devices as "trusted" or not, before granting access to networks and applications from any location. The technology also ensures that users and devices are protected against attacks such as phishing and other threats, without requiring software or applications to be up to date.
The ZTNA is the only technology tool that can preserve security, usability and user experience. There are few solutions that can do all of this at once, hence the ZTNA's unsuspected potential. Indeed, this technology is:
- Intuitive, it offers the same user experience as in the office, with the same level of security.
- Scalable, it allows to manage a small number of teleworkers as well as the transition of all employees to mass teleworking.
- Agile, the ZTNA uses the cloud to give IT and security teams the agility they need to facilitate IT processes.
- Less expensive, the ZTNA eliminates the need for expensive, complicated, and non-scalable VPN solutions.
