Security breaches rocked 2017. The global outbreak of WannaCry and NotPetya ransomware fundamentally changed the threat landscape, and attacks on organizations such as Equifax put astonishing amounts of data into the hands of hackers. It was a horrific year for data privacy and security—“cyber-geddon,” according to the BBC—and a wake-up call for CISOs and corporate legal departments everywhere.
This reality, along with increases in the portability of data, employee mobility and penalties for failing to comply with strict data protection regulations such as the EU GDPR raise the question: “What more can organizations do to protect themselves and their stakeholders?” An integral part of the answer is data loss prevention (DLP).
DLP identifies, monitors and protects data in use, data in motion on your network, and data at rest in your data storage area or on desktops, laptops, mobile phones or tablets. Through deep content inspection and a contextual security analysis of transactions, DLP systems act as enforcers of data security policies. They provide a centralized management framework designed to detect and prevent the unauthorized use and transmission of your confidential information. DLP protects against mistakes that lead to data leaks and intentional misuse by insiders, as well as external attacks on your information infrastructure.

1. You aren’t sure where your company’s confidential data is being stored, where it’s being sent and who is accessing it.
DLP technology provides IT and security staff with a 360-degree view of the location, flow and usage of data across the enterprise. It checks network actions against your organization’s security policies, it and allows you to protect and control sensitive data, including customer information, personally identifiable information (PII), financial data and intellectual property. With a thorough understanding of this data, your organization can set the appropriate policies to protect it and make risk-prioritized decisions about what assets need to be protected and at what cost.
2. Your company has a plan for protecting data from external intruders, but does not protect against theft and accidental disclosure of sensitive information by employees and partners.
Not all data loss is the result of external, malicious attacks. The inadvertent disclosure or mishandling of confidential data by internal employees is a significant factor. According to Verizon’s 2018 Data Breach Investigations Report, 28 percent of attacks involved insiders. The insider threat can be particularly difficult to guard against—it’s hard to spot, if someone is using their legitimate access to data for nefarious purposes. DLP can detect files that contain confidential information and prevent them from leaving via the network. It can block sensitive data transfers to Universal Serial Bus (USB) drives and other removable media, and offers the ability to apply policies that safeguard data on a case-by-case basis. For example, if a security event is detected, access to a specific endpoint can be blocked instantly. Policies can also quarantine or encrypt data in real-time response to events.
3. You would like to monitor your organization for inappropriate employee conduct and maintain forensic data of security events as evidence.
Insiders represent a significant risk to data security. An employee who emails a work-related document to his personal account in order to work over the weekend may have good intentions. However, he or she poses a tremendous threat when there is confidential data involved. DLP technology offers 360-degree monitoring that includes email (both corporate accounts and webmail), instant messages, keystrokes typed, documents accessed and applications used. It also allows you to capture and archive evidence of incidents for forensic analysis. With DLP, you can limit and filter Web surfing, and control which applications employees can access. It is an invaluable tool in the effort to stop dangerous or time-wasting activities, and helps to detect problems before they can damage your business.
4. You are uncertain of your organization’s level of protection for confidential data in cloud applications and storage.
Data is increasingly being moved to applications in the cloud—an environment in which it is not apparent where data will be physically stored and processed. DLP recognizes confidential data, ensures that it does not make its way into the cloud without being encrypted, and is only sent to authorized cloud applications. Most cloud DLP solutions remove or alter classified or sensitive data before files are shared to the cloud to ensure that the data is protected when in transit and in cloud storage.
5. Your organization would like to proactively prevent the misuse of data at endpoints, both on and off the corporate network.
DLP technology monitors all endpoint activity, on the corporate network or off. It can block emails or attachments containing confidential data, enforce policies on the transfer of data to removable media devices such as USB thumb drives, and even prevent activities such as printing, copying and pasting. DLP offers complete data visibility and control, ensuring that employees, third-party vendors, contractors and partners are prevented from leaking your data—intentionally or inadvertently.
