All Security Technologies Are Not Data Loss Prevention
While security technologies may share the common goal of protecting an organization's sensitive data, not all can -- or should -- be called data loss prevention
I recently read an article that made the following assertion (paraphrased in my words): Every part of an organization's security technology arsenal is, in fact, data loss prevention (DLP). At the very heart of every organization's information security strategy is the blessed data, the object of the safeguarding effort. Any and every security tool or technology that serves to protect that data, therefore, can be deemed DLP.
One example in the article suggests that disk encryption could very well be DLP to an organization with a mobile workforce because both technologies share the objective of data protection. If that logic holds true, then we might as well drop in uninterruptible power supplies and data recovery services to the growing list of DLP products because each one helps protect data. Why not add laptop privacy screen filters and portable hard drives, while we're at it? In fact, let's drop in all 3,009 products once listed on the website of an office supply giant in its innovative "DLP" category.

Of course, I'm being facetious to emphasize my point. The unfortunate reality is the marketplace is flooded with "data loss prevention" tools that wouldn't know sensitive data if it bit them in the power cord. Where should we draw the line?
While all security technologies may share the same objective of protecting an organization's critical data, different tools arrive at that objective from different angles, often using completely different technologies. Those different technologies require unique labels in order to distinguish one technology from another. (Imagine a world where all security technologies were referred to as "data loss prevention.")
Those who share the "all-security-is-DLP" mindset seem to disregard this point, claiming that any security tool can be DLP to one organization, while a different security tool can be data loss prevention to another organization. I agree that DLP often has different meanings to different people.
The problem I have with this approach is: I do not agree this should be the case.
While most of us can agree that data protection is the overarching goal of information security, the reality is very few information security defenses work at the data level. DLP technologies deliver something that other data protection tools do not -- and simply cannot: They monitor the actual data, detecting and preventing the leakage of that sensitive data. What's more, true DLP technologies accomplish this colossal task comprehensively, through deep packet inspection, using a high level of content-awareness across all major leakage vectors: data in motion at the network gateway, data in use at the endpoint and data at rest in storage.
For years, many argued the phrase "data loss prevention" was too broad and did not accurately describe the true benefit of these technologies. I would argue an even more significant problem is the generally accepted notion that data loss prevention is a product, rather than the complete process of safeguarding data. Regardless of how I feel about these arguments, both are now rendered moot. It's too late to turn back the clock. The marketplace has spoken definitively: DLP is the descriptive term for that category of solutions that prevent the leakage of sensitive data.
By accepting and promoting this reality, the marketplace -- and specifically those organizations with data protection needs -- will better understand how to meet requirements with the right tools for the greatest data protection benefit.
