Say Good Bye to Data Leakage--

A recent survey of top security professionals carried out by a leading Consultancy firm revealed some scary but realistic statistics:

1 in 3 companies investigated a breach of confidential data last year.

1 in 4 companies experienced an “embarrassing” leak of confidential information.

1 in 5 emails contains a legal, financial or regulatory risk.

If you are like most corporations, you are finding yourself in the midst of an information explosion. Sensitive data is no longer controlled under lock and key in data centres or file cabinets. Sensitive data is everywhere. This data is an easy prey to leakage which will hamper the competitive advantage that you may have in the market.

This is where Data Leak Prevention (DLP) technology/products come to your rescue.

What is DLP?

DLP is nothing but the use of various techniques to prevent critical data from unnecessarily leaving the organization. DLP products can be defined as:

“Products that, based on central policies, identify, monitor, and protect data at rest, in motion, and in use, through deep content analysis.”

Some of the most common techniques used in these products to detect and prevent unauthorized extrusion of data are:

1. Rule bases/ Regular expressions

2. Database fingerprinting

3. Exact File Matching

4. Partial Document Matching

5. Statistical Analysis

6. Conceptual/Lexicon

7. Predefined Categorization.

What are the main features to look out for in a DLP solution?

In this day and age, it is impossible to expect your employees to be fully cognizant and ready to comply with all data protection compliance rules. Hence look for a DLP technology that can:

1. Protect sensitive data without slowing down your business or frustrating employees trying to do their job.

2. Meet data protection compliance guidelines through the ability to encrypt, redact, block or quarantine sensitive data before it damages your business.

3. Real time performance

4. Virtually zero false-positive rates.
