data loss prevention (DLP)

This definition is part of our Essential Guide: How to conduct a next-generation firewall evaluation

Data loss prevention (DLP) is a strategy for making sure that end users do not send sensitive or critical information outside the corporate network. The term is also used to describe software products that help a network administrator control what data end users can transfer.

DLP software products use business rules to classify and protect confidential and critical information so that unauthorized end users cannot accidentally or maliciously share data whose disclosure could put the organization at risk. For example, if an employee tried to forward a business email outside the corporate domain or upload a corporate file to a consumer cloud storage service like Dropbox, the employee would be denied permission.

Adoption of DLP is being driven by insider threats and by more rigorous state privacy laws, many of which have stringent data protection or access components. In addition to being able to monitor and control endpoint activities, some DLP tools can also be used to filter data streams on the corporate network and protect data in motion.

DLP products may also be referred to as data leak prevention, information loss prevention or extrusion prevention products.

Data loss prevention (DLP) is a strategy for making sure that end users do not send sensitive or critical information outside of the corporate network. In order to protect data at rest, we must have DLP. This allows people limited access to confidential information.

Still the safest way of data sharing is Virtual Data Rooms. VDR providers consider data security as a top priority: all documents are encrypted using a strong 256-bit encryption which prevents access of unauthorized users, including their own IT personnel. The only my advice is to deal with iDeals Solutions (http://www.idealsvdr.com), in my opinion, they are the best.

I think the only way to do it is to ensure that all devices are protected. And since you cant force people to backup you need something that does it for you like Cibecs.

Data loss will always have some risks. In order for your employees to do their jobs some need greater access to the data. In this case if comes down to trust. Can you be assured that they do not load data to removable media and take it out the front door ? IF you have happy employees yo may have no issue. It's the angry disgruntled worker I'd be afraid of.

I have recently discovered quite new free device control tool, that prevents sensitive data leak mainly through USB drives. I think this software actually can help a company to control what data and users can transfer. Link: http://device-control.data-leak.com/

I work in a <a href="http://www.nektra.com/custom-windows-software-development/api-hook-filter-drivers/custom-data-loss-prevention-dlp-software-development/">data loss prevention development company</a>. We see that companies want the cure of data breaches but nowadays that is impossible because you can leak data with any device you hold.
We see that most of our customers are willing to prevent employees to leak sensitive data but we see that most issues are related to mistakes or lost devices.
