Data Loss Prevention Tools

What is data loss prevention?

Data loss prevention (DLP) is the control of access to the data that your company holds. A data loss prevention strategy makes sure end-users aren’t able to intentionally destroy or steal data.

It’s important to have a data loss prevention policy in place at your enterprise. This can cover: data loss prevention tools, intrusion prevention systems, system information, event management, endpoint protection, and anti-malware systems are areas of IT security that overlap.

When you come to tighten up your system protection, you will find that you don’t need one of each of these because just one will take care of many tasks, including blocking access to the system and protecting data simultaneously. With the correct policy and systems in place, you will be able to reduce or eliminate data loss incidents across your business.

While the EDR looks for incoming threats, Falcon Device Control scan for data exfiltration attempts.

Key Features:

  • Control on data passing onto memory sticks
  • Variable security set by policies

It is very easy to disable USB ports entirely. However, this approach is not always suitable. For example, USB ports can be used for many features, not just for removable storage. You might want to keep USB ports active but just control what data passes over them.

The question of data movement is not an all-or-nothing decision either. You could allow certain types of data to be moved onto USB devices while blocking more important data collections from being moved. So, the control of USB devices needs to be finely tuned.

With Falcon Device Control you get to specify which types of devices can be connected or, more easily, define which device types are banned. The control extend to user access controls, so you can allow some users or user groups to use USB devices while blocking all others.

The software for Falcon Device Control is able to identify and document all devices as they are connected to a USB port on an endpoint. You can install this software on all of your endpoints and nominate one device to host the server. Thus, you get all activity reports for all devices forwarded to one dashboard for consolidated reporting.


  • Distributed implementation
  • Centralized dashboard
  • The possibility to block certain types of devices
  • The ability to interface with access rights managers
  • Fast local controls


  • The Falcon family doesn’t include controls over other channels of data exfiltration, such as email attachments.

8. SecureTrust Data Loss Prevention

SecureTrust DLP

This is a good option if you are having difficulty working out your DLP security strategy. When you install the software, it will present you with a list of 70 policies, which you can activate. Reading through the explanations of each will probably give you some suggestions for data control that you hadn’t even thought of.

Data Loss Prevention is part of a suite of security management tools from SecureTrust. The company also produces a SIEM tool, which is a great option for detecting and blocking intruders. These two tools can work together, although SecureTrust states that the DLP utility is efficient at detecting malicious activity by itself.

The security system scans all channels of communication for privacy violations. These include file transfer applications, email, chat apps, file sharing systems, blogs, and social media. The response mechanism of the tool automatically blocks transfers midstream. It will also identify the correspondents at each end of the data transfer.

This company’s data loss prevention solution includes a great deal of assistance to help you get your data protection strategy in place. This is because the package includes policies, so you just have to check which of those fit with your security strategy requirements and activate them.

The remediation module of the tool takes a different approach to user activity management to that used by the other utilities in this list. Rather than alerting IT department staff of unwelcome activity and automatically shutting down the user’s account or file access, it issues a warning directly to the user.

The ethos behind this approach is to educate the user community about the rules of data access rather than trying to catch them out when they cross a line that they didn’t know about. The data usage scrutiny of the system extends to emails.


  • Good for companies who want to help educate users as they attempt to access information inappropriately
  • Supports major compliance standards
  • Supports email scanning that can automatically restrict emails from being sent

Priorities for DLP

The first and most obvious topic to deal with when trying to prevent the data your business stores is to control access to it. However, this is not your only task. In order to prove compliance with data security standards, you are going to need some evidence. So, constant transaction logging is needed, and you are going to need to store those logs for years so that they can be available for spot audits. Constant self-auditing is also necessary to ensure that security procedures are sufficiently strong.

Although failure to protect data is a setback, any leakage should not be covered up. Non-disclosure of data leakage is a big mistake. It will cause you to lose your accreditation. Data protection standards all include protocols for data loss notification and they should be followed.

Surprisingly, most organizations don’t properly track all of the locations on the system where data is stored. Staff might keep notes in documents on their desktop computers and forget to delete them; other local stores, such as contact databases can sometimes be overlooked. It is important to centralize the data storage and track access to it.

The data held by your company is a potential money earner for hackers. So, you have to properly defend your network against intrusion. However, authorized users also present a security risk. They might be tricked into passing on data to outsiders or might be motivated through resentment or greed to steal the company’s data. Preventing the copying of data onto portable devices, or printout, or sending data out through email, or a chat app is another important requirement of your DLP system.

Compliance to a data security standard is also important in order to win contracts. The public sector is very strong about protecting personal data and they ripple that priority through all of the services that they buy. So, if you don’t implement effective data loss prevention you will be locked out of the opportunity for new contracts. The need to comply with the standards of the public sector continues through the supply chain. So, even if you don’t bid for public sector contracts, your ability to do deals with businesses that do work for the public sector will be reduced.


Data loss events were once seen as an unfortunate risk. The IT industry and the legal systems of most advanced economies recognize that no IT system can ever be 100 percent secure. However, the requirements for companies to take all possible steps to prevent data disclosure have become far stricter in recent years.

Many businesses are unable to fully identify all of the locations of data storage and fixing that issue is the first step to a comprehensive data loss prevention strategy. Getting the right DLP tools is very important and you won’t be able to fully comply with the law or data security standards without them. Without standards accreditation, you will be barred from bidding for many contracts and without full data loss protection systems you run the risk of a disclosure event, which could lead to destructive prosecutions.

You run a great risk of your business being destroyed if you don’t have a data protection strategy. Data loss prevention software is no longer optional.

Data Loss Prevention Software FAQs

How can cloud computing prevent data loss?

The data loss risk is no different in cloud computing than it is with onsite infrastructure with the exception of the communication channel between your site and the cloud host.

  1. Locate all sensitive data
  2. Categorize data according to security standards requirements
  3. Track all access to categorized data
  4. Track changes to device configurations
  5. Monitor log file records for unexpected user behavior or unauthorized traffic
  6. Install all updates and patches to firmware, operating systems, and software
  7. Secure all access channels across the internet

What is a data loss prevention policy?

A data loss prevention policy is a set of rules and workflows laid down by your business to define how to allow access to data and protect the information that you hold. This strategy applies to working procedures, access rights management, activity monitoring procedures, reporting requirements, and disaster recovery measures.

What is a DLP alert?

A DLP alert is a system-generated message. A DLP tool monitors activities, such as data storage access and network traffic. The software will raise an alert if an activity lies outside registered acceptable behavior. The alert does not necessarily mean that a data loss event has occurred. It could identify a potential risk or a system weakness that the actions of intruders have exposed without successfully touching the target data. An alert should instigate an investigation into the necessity of adjusting security standards or taking some other preventative measures or it could indicate a security breach in progress.
