"Everyone should carefully consider what information they share online about themselves," said Erkki Mustonen, an information security specialist at F-Secure, a computer security company based in Helsinki.
Together with writer Petteri Järvinen, Mustonen agreed that there were no good options to replace the US-managed network services.
Snowden's revelations have, however, given many firms in the information security industry a good platform to compete with big American firms.
"More recently, options have come up. For example, the domestic cloud server or VPN service is certainly a safer rival to those in US." said Järvinen.
