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.

1. Trellix Data Loss Prevention

Solid data loss prevention service for deep data analysis

Reasons to buy


Forensic analysis


Intelligently prioritizes sensitive data

Reasons to avoid

Complex settings

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. It can also ensure the same protection policies are applied across all aspects of your IT infrastructure, whether on-premises networks or cloud-based applications.

An easy-to-use data loss prevention service

Reasons to buy


Single console


Simple to use

Reasons to avoid

Could be overly simplistic for some

Check Point Data Loss Prevention combines a variety of different cybersecurity processes to help businesses prevent data from being leaked or sent accidentally to the wrong person. It aims to educate users on the risk of data loss and help them respond to incidents as quickly as possible.

It does this by tracking data use across services, not least email, web browsing, and file-sharing. It also takes pre-emptive steps to prevent data-loss by providing automated alerts to users to ensure proper data-handling, without having to involve security teams directly.

This is a less complicated system than some of the others listed here, sporting a centralized management console for security policies. There are also a few preconfigured rules, so you don’t have to worry about creating new ones if you don’t have the time or technical knowledge. 

No pricing flat-rate pricing options are made available, so you will need to contact sales for a quote. However, there is a free online demo you can use to test out its features.

3. Digital Guardian Endpoint DLP

A powerful data loss prevention service with broad coverage

Reasons to buy


Windows, Mac and Linux endpoints


On-premise, cloud or hybrid

Reasons to avoid

Opaque on pricing

Digital Guardian Endpoint DLP is one of the broadest data loss prevention systems you can get. It’s been designed to work with Windows, Mac and Linux endpoints, which is perfect if you use a plethora of desktop systems within your firm. As soon as you set it up, it’ll begin tagging and classifying datasets, a process that can otherwise prove time-consuming.

Flexibility and scalability are strengths of this particular DLP offering. In terms of the former, you can deploy the Digital Guardian platform on-premise, or as a cloud-based system, or indeed a hybrid of both. And when it comes to scaling, a single management server can cover up to 250,000 users, no less. Not that your business is likely to have that many employees, but if you need a system that scales well, then this is obviously worth bearing in mind.

Digital Guardian also boasts a series of add-ons which can extend the product and offer elements like advanced encryption for better data protection.

As with the other services listed, there is no standard pricing made available due to custom-user requirements so you will need to contact Digital Guardian for a quote. However, you can test out a demo before making a buying decision.
