This security model has been seen as increasingly inadequate, not least because of the need to facilitate secure access for remote employees. These challenges have raised the popularity of zero trust network architecture (ZTNA), in which users and devices are treated as untrusted by default, both within and without the organisational network.
- Regular training of staff will remain central to ensuring robust cybersecurity.
- ZTNAs are likely gradually to replace VPNs in enabling secure access to organisational data and digital resources for remote workers.
- Industrial standards and commercial solutions for ZTNA will continue to be developed and refined.
