The best data loss prevention services (DLP) provide an easy way to protect your business against data loss.
The immediate line of defense is to ensure that business data is securely stored in the first place. The next is to ensure that only the correct individuals or usergroups have the right permissions for the right data.
In that regard DLP services runs somewhat differently to other data security software such as disaster recovery software, which simply aims to keep up to date backups, or endpoint security software which aims to prevent unauthorized access to systems.
Additionally, there is also employee monitoring software that aims to prevent employees compromising business data and IT infrastructure by ensuring proper access permissions are in place.
DLP software has to go further than all these steps, however, and be proactive rather than reactive about preventing data loss. This is especially when regulations such as GDPR threaten big fines for lapses in data control that sees confidential consumer data accessed by unauthorized third-parties, or otherwise released into the public domain.
Therefore DLP software will often use AI to watch for suspicious behavior, in a similar way that they would for virus activity, to ensure that anything outside of normal parameters can be stopped before causing damage or loss to data, and that IT security can be properly alerted to the potential problem.
DLP software has to be good, and while there are a lot of contenders, here we’ll list the best DLP software providers currently available. We’ve compared these software across numerous factors, like the ease of setup, simplicity of settings, ease of use, scalability, cloud coverage, and pricing, among other things.
We’ve also highlighted the best data visualization tools.

Trellix Data Loss Prevention (formerly McAfee Total Protection for DLP) is, like some other systems, highly scalable and can be tailored for the needs of your company. The big difference, though, is that it places an emphasis on forensic analysis.
Indeed, Trellix goes a step further than most by exploring ways that data may have been leaked in the absence of internal compliance rules and regulations. That’s handy for firms that may not have concrete corporate rules in place.
Another great thing about this solution is that it’s an intelligent system which can identify and prioritize more sensitive data. There’s also location and application tagging, which makes it easier to put data protection strategies in place.
The software aims to ensure you remain compliant, while simplifying deployment and management with a centralized dashboard for monitoring.
