Increasingly, smaller and medium-sized companies are offering remote access to corporate systems through VPNs as well as the large corporates. But are VPNs up to the job? There is evidence that small and medium enterprises are not up to speed with the risks created by giving workers with laptops VPN access to the company's network across public telecommunications systems.
