In this age of strong Data Privacy laws like GDPR and CCPA, Data loss prevention (DLP) systems are becoming a critically important IT security tool. But, before choosing the right DLP solution, businesses need to make sure that they create the proper security context in terms of what’s acceptable and what’s not.
Data loss prevention (DLP) systems have become a hugely popular tool in the arsenal of corporate information security departments. The best DLP services aim to prevent the loss of data through malicious exfiltration by third-parties or unsecured storage. The first line of defense is to ensure that the data is securely stored in the first place. It also ensures that only individuals or user-groups with the right permissions access the right data.
With the exponential growth in data volumes and how data is used and stored, the opportunity for data theft and the unintentional disclosure of sensitive data multiplies. The cybersecurity market provides multiple DLP solution choices, and knowing what the needs of the organization are and how to enhance data security within it, may feel overwhelming.

Content Blocking
A DLP system should prevent data leaks caused by malicious software or employees, and this can only be achieved by blocking a suspicious operation.
A potential data breach due to the lack of a blocking regime can prove to be costly for an organization. Additionally, the regulations require building protection against data leaks with a blocking mode; otherwise, it can result in violators getting severely fined.
Therefore, the best DLP solution needs to be able to block communications channels with suspicious content. The clients should also be able to fine-tune all settings related to content blocking.
DLP with Context and Content Awareness
The most effective approach to data leakage prevention is contextual control. But, there are many scenarios that require a deeper level of awareness that contextual parameters alone may not be able to provide. Security administrators can gain greater data security compliance by passing all data flows through content analysis and filtering rules before allowing the data transfer to complete.
A DLP system should provide both contextual and content-based controls for maximum leakage prevention at minimum cost. Its multi-layered inspection and interception engine can provide granular control over a full range of data leakage pathways and ensure that no sensitive data escapes through content analysis.

Implementation Options
A good DLP system supports many implementation options. It simplifies the task of combining a DLP system with the existing IT infrastructure allowing enterprises to flexibly balance the functional and computational load while controlling various channels.
In addition to the endpoint agent, a mature DLP system also offers the following implementation options:
- Mail server integration – Enables enterprises to monitor their internal email additionally.
- The option of receiving mail correspondence from a technical mailbox.
- The option to integrate Internet Content Adaptation Protocol (ICAP) with the existing internet gateway.
- A separate mail transport server
Inaccessible Enterprise Network
In addition to performing content analysis, the DLP agent must also transmit information about events and other data to the server. And, if the main archive is not accessible, all the important data should not be lost.
A good DLP system should allow businesses to set the appropriate rules for each situation.
