- 5. Archiving is much more difficult Data on personally owned devices is more difficult to archive because some of it is stored on the mobile devices themselves, not necessarily on the backend servers that are operated by IT. Monitoring content is more difficult Monitoring content sent from and received by mobile devices is much more difficult than it is from a conventional desktop infrastructure. This means that legal and regulatory violations are easier to commit, which can lead to adverse legal judgments and regulatory sanctions. Users are more autonomous Mobile users tend to be more independent from IT’s control because they are outside of the office and so IT cannot control how devices are used. Compliance is more difficult According to an Osterman Research survey, nearly two in five organisations find managing policies for e-discovery or regulatory compliance to be difficult or very difficult, while 35% find managing other types of policies to be this difficult. Managing mobile policies for issues like ediscovery and regulatory compliance is slightly more difficult than managing other types of policies. The environment is more diverse The normal desktop infrastructure consists of mostly Windows machines and possibly some Macs and maybe a few Linux machines. The typical BYOD environment, on the other hand, is much more diverse, typically consisting of iPhones, Android smartphones, iPads, Windows phones, BlackBerry devices, and other platforms. Further complicating the management of this environment is that there are multiple versions of the operating systems in use, each of which can provide users with slightly different capabilities.

- KBExplain graphicsLet us look at different aspect of our joint solution that deliver the three key capabilities – first being optimzied access, next comprehensive security and lastly validated solution.
- Bradford Networks’ Network Sentry maintains username information for all non-corporate device types. Because Network Sentry is “network aware”, it knows in real time when any device connects to the network. Network Sentry then immediately sends username and IP address information to the User-ID Palo Alto Agent, allowing the Palo Alto Networks firewall to apply policies based on the user information supplied by Network Sentry.
