Here’s some more content that’s going into the updated version of Understanding and Selecting a Data Loss Prevention Solution (hopefully out next week). Every now and then I get questions on DLP SaaS, so here’s what I’m seeing now…

DLP Software as a Service (SaaS)

Although there aren’t currently any completely SaaS-based DLP services available – due to the massive internal integration requirements for network, endpoint, and storage coverage – some early SaaS offerings are available for limited DLP deployments. Due to the ongoing interest in cloud and SaaS in general, we also expect to see new options appear on a regular basis.

Current DLP SaaS offerings fall into the following categories:

  • DLP for email: Many organizations are opting for SaaS-based email security, rather than installing internal gateways (or a combination of the two). This is clearly a valuable and straightforward integration point for monitoring outbound email. Most services don’t yet include full DLP analysis capabilities, but since many major email security service providers have also acquired DLP solutions (sometimes before buying the email SaaS provider) we expect integration to expand. Ideally, if you obtain your full DLP solution from the same vendor providing your email security SaaS, the policies and violations will synchronize from the cloud to your local management server.
  • Content Discovery: While still fairly new to the market, it’s possible to install an endpoint (or server, usually limited to Windows) agent that scans locally and reports to a cloud-based DLP service. This targets smaller to mid-size organizations that don’t want the overhead of a full DLP solution, and don’t have very deep needs.
  • DLP for web filtering: Like email, we see organizations adopting cloud-based web content filtering, to block web based attacks before they hit the local network and to better support remote users and locations. Since all the content is already being scanned, this is a nice fit for potential DLP SaaS. With the same acquisition trends as in email services, we also hope to see integrated policy management and workflow for organizations obtaining their DLP web filtering from the same SaaS provider that supplies their on-premise DLP solution.

There are definitely other opportunities for DLP SaaS, and we expect to see other options develop over the next few years. But before jumping in with a SaaS provider, keep in mind that they won’t be merely assessing and stopping external threats, but scanning for extremely sensitive content and policy violations. This may limit most DLP SaaS to focusing on common low hanging fruit, like those ubiquitous credit card numbers and customer PII, as opposed to sensitive engineering plans or large customer databases.
