As IT tools become more complex and all-encompassing, the gaps in DLP are increasing

Microsoft DLP Gaps and Limitations

Oftentimes people simply have the wrong idea of how Data Loss Prevention (DLP) works. 

 

Many people view DLP platforms as a homogenous solution that “covers” the issue of data loss. 

 

The reality however is much more complex. 

 

Far from a singular challenge, DLP deals with a wide array of potential weaknesses in both the systems and procedures through which data is created, stored, and transmitted. 

 

What this means practically, is that as IT tools become more complex and all-encompassing, the gaps in DLP are increasing. The more ways there are to access and manipulate data, the more holes in the fence there’ll be. It’s that simple. 

 

Teams

Take the much-lauded Microsoft Teams, one of the most popular business communication platforms on the market.

 

To be sure, the folks at Microsoft know a thing or two about data security, and their Data Loss Prevention is rich in features and has a very wide adoption. Still, it is not uncommon for weaknesses to be discovered in the service. 

 

Two of the most exploitable issues on Teams have to do with the access protocols for external users. First when a user is a Guest in an external tenant, and second when a user joins a meeting hosted by an external user.

 

Let’s examine the practical ramifications of this. Suppose your company has solid DLP policies and tools in place. All internal communications and transmissions of data outside the network are, at least in theory, protected. But now one of your employees goes to communicate with a collaborating firm using Microsoft Teams and utilizes their tenant as a Guest User. In that scenario, your security rules will not be replicated on that external tenant. This will allow the transmission of messages and files that violate your DLP policies. 

 

Another consequence of the same flaws creates a DLP gap in external meetings. DLP for external chat sessions–ie, a chat with an external user–will only work if both the sender and the receiver are in Teams Only. If they aren’t in this mode, then DLP policies may very well not be activated.
 

Why Smart DLP Matters

These and other issues with legacy communication platforms highlight an essential truth when it comes to protecting data: static defense will always have flaws.

In order to assure data is really being protected, a dynamic and adaptable solution is what’s required

Best in Class Solution!

I am an investor at Bain Capital specializing in cybersecurity and infrastructure. We have been doing a deep dive into the enterprise data space since our investment in Ata#####, and have found data loss prevention one of the largest pain points. Many firms lack comprehensive data privacy policies and solutions. We see GTB’s platform as a direct response to address this problem, and we feel it is a best-in-class solution. Nov. 16, 2022 lkin

Blue Cross ... Meeting our complicated needs

Over the years, our environment has become increasing complicated as we continue to improve our security and data protection posture. GTB Technologies has demonstrated time and time again its ability to be agile in meeting our needs. We have seen other (larger) companies struggle to understand issues and communicate them within their company to work toward delivering a solution. This has not been the case with GTB.

LA Metro

“Security is a large initiative for LA Metro, as we continue to grow our network and infrastructure to meet our growing needs that support those living, working and exploring LA County,” said Los Angeles County Metropolitan Transportation Authority Senior Director of Engineering Richard Bezjian. “Our existing email protection would simply not be enough on its own to deliver the strength of protection required to identify and stop today’s cyberattacks. SonicWall delivers additional security efficacy with a competitive TCO.” utilizing GTB Inspector for Data in Motion OEM solution

City & County of San Francisco

"Each department faces unique regulatory challenges and data security must both protect vital data without interfering with critical business. That's why the City replaced its previous DLP and encryption solution with Avanan Data Protection and Encryption. Within days of deployment, the City saw a 30% improvement in the use of data encryption. " GTB catches the events which others missed!

Forcepoint Investor - Private Equity

I have been working closely with Forcepoint. They are highly impressed with GTB’s all-in-one DLP solution and its ability to discover, classify, detect, and protect companies from threats in a seamless manner.

GTB Is A DLP Market Leader

Our deployed Digital Guardian deployment was failing miserably. The product did not function properly and support was non-existent. The inability to address audit issues, inaccurate data provided by the system, and the lack of reporting prompted us to implement GTB after a detailed evaluation of DLP products.

Most Advanced DLP

"GTB has one of the most advanced DLP solutions on the market and we are proud to have them as a partner. As soon as we added them to the Avanan Cloud Security Platform we started seeing our customers testing and then purchasing their solution on our platform" Gil Friedrich, CEO Avanan
