Trying to prevent data leakage. Especially when laptop is out of office.

We are trying to lock down our data to prevent leakage.  I'm not taking about un-authorized access.  I'm talking about making sure that data that people are authorized to access doesn't get into the wrong hands ... such as competitors.

I can lock down my firewall to prevent access to certain sites.  I can block webmail internally.  I can restrict email ... somewhat.   But at least I can see what was sent to who.

However if a file is on a laptop and the laptop is not in the office, how can I prevent them from emailing that to someone via webmail?   Or downloading to a web site?

Also relative to data leakage.   We have folks that may travel and occasionally need to visit the business center of the hotel to print documents.   We have disabled the use of USB drives because of security concerns.  If they use OWA, that will let them print, but it leaves a thumbprint on the PC.   And it also gives the ability to leave the document open or download the file without us knowing about it.   I've tried to find ways to open and print, but not allow them to save, but have been unsuccessful at doing so.  When I restricted via HTML access only, the formatting was all messed up when we tried to print it.

To add...Indeed endpoint lockdown is key and if user is given admin right, they can simply bypass and leak info. Imagine if they have dropbox and can be installed to file sync with their personal account as well as business account, such bridging leads to leaks that can be intentionally or unintentionally.

DLP can be at the point of egress and ingress on critical services such as network segment, email services, file, database and web services since they are most of the times holding those crown jewels. Least privileged principle, remove remote admin and access, segregate high risk and low risk service segment, endpoint/appl/ext device lockdown checks and audit trail can deter and help reduce exposure.

There are even anti-theft mechanism in endpoint and remote wipe in event of device loss or total wipe out for revocation. But to proactively alert for leaks will be good to consider even external crawling or social services scouting for organisation leaks in underground and public forum and social media sites..

Use DeviceLock DLP to control local devices (USB, FireWire, etc.) and network resources such as drop box, google drive and so on.
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.
