Protect sensitive data

The Masking feature of the GigaSMART® engine provides customizable data protection by overwriting specific packet fields with a set pattern. Sensitive information is safeguarded during network analysis.

Confidentiality and compliance are crucial for a broad range of government and private organizations alike. Regulations in the financial, insurance, and healthcare industries require that sensitive data be protected. Penalties for non-compliance of such regulations can be severe, resulting in fines or even imprisonment. Masking permanently obscures the data before sending it to security and monitoring tools. Regulatory and privacy compliance becomes easier because the sensitive data is never seen, processed or stored by these tools.

Benefits of the Masking feature:

• Supports compliance with stringent data protection regulations.
• Protects network and security engineers from inadvertently being exposed to sensitive or confidential data.
• Provides an added level of data protection in cases where network monitoring and analysis functions are outsourced.
