Proofpoint
Network Content Sentry
Prevent leaks of confidential information
Proofpoint
Network Content Sentry option inspects all outbound
network traffic in real-time—applying policies defined in
the Proofpoint Regulatory Compliance and Digital Asset
Security modules—to detect confidential information, private
customer or employee data (including private healthcare,
financial or identity information) and other sensitive
content that may leak outside the enterprise. When such
breaches are detected, the system actively alerts managers
(such as compliance officers) so appropriate actions can be
taken.
Benefits of Proofpoint Compliance Solutions:
- Extends Proofpoint's data loss prevention capabilities to HTTP and FTP protocols.
- Easily managed through Proofpoint's centralized, web-based administration interface.
- Applies your Proofpoint Content Compliance, Regulatory Compliance and Digital Asset Security policies to webmail, blog and message board postings, file transfers and many other common risk vectors.
- Proofpoint's unified appliance architecture makes deployment fast and easy.
Features:
As enterprises have become increasingly concerned about enforcing outbound email policy violations, defending against leaks of confidential information and ensuring compliance with regulations, they are also realizing the information protection risks presented by other outbound messaging streams including HTTP and FTP traffic. A recent survey by Proofpoint and Forrester Consulting found that about half of companies polled were concerned or very concerned about web-based email as a source of private information leaks. More than 43% shared the same concerns about postings to blogs and other types of message boards.The Proofpoint Network Content Sentry extends Proofpoint's data loss prevention and information protection features to additional outbound message streams including web-based email, blog and message board postings and other HTTP- or FTP-based activity.
Enhanced protection for intellectual property
and improved compliance solutions
By adding the Proofpoint Network Content Sentry to
your Proofpoint email security software or anti-spam
appliance deployment, you can apply the same content
security, regulatory compliance and acceptable use
policies defined for SMTP-based email to HTTP and
FTP protocol-based communications.
- Intellectual property and confidential
information protection: In conjunction with
the Proofpoint Digital Asset Security™ module,
the Proofpoint Network Content Sentry monitors
outbound network traffic for any type of
confidential asset. Leveraging Proofpoint MLX™
message classification techniques, Proofpoint
Digital Asset Security analyzes and classifies
confidential documents and then continuously
monitors for that information, or parts of that
information, in outgoing network traffic.
Proofpoint Digital Asset Security can be used to
protect hundreds of document types including
email messages, text files, word processing
files, source code, CAD drawings, spreadsheets
and presentation formats.
- Privacy protection and regulatory compliance: In conjunction with the Proofpoint Regulatory Compliance™ module, the Proofpoint Network Content Sentry monitors outbound network traffic for a wide array of non-public information including PHI (protected health information including drug names, disease names, patient identifiers and treatment codes as defined by HIPAA), personal identifiers (including US Social Security Numbers and UK National Insurance Numbers) and personal financial information (such as credit card numbers and ABA routing numbers). Proofpoint's "smart identifiers" ensure accurate detection of private information with low false positives.
Robust HTTP and FTP Compliance Solutions
The Proofpoint Network Content Sentry intelligently
captures and reconstructs all outbound HTTP and FTP
protocol traffic at high data rates. All HTTP
posting activity-such as web-based email posting
(including webmail services such as MSN Hotmail,
Yahoo! Mail, AOL Mail and Google GMail), blog
postings, message board submissions, use of
web-based file storage systems (such as GMail FS)
and other general posting activity-is intercepted
and scanned for information leaks and policy
violations.
The system monitors both active and passive mode FTP transmissions of binary or text files sent to remote servers. As with HTTP posting, a wide variety of policies can be enforced around FTP activity, including monitoring for specific files, file size limits and detecting FTP transmissions to inappropriate destinations.
Flexible policy definition and incident
management
The same interface used to define outbound
SMTP-email policies is used for setting Proofpoint
Network Content Sentry policies. Each policy can
trigger based on specific document type and a
customizable document similarity score. HTTP- or
FTP-based messages that trigger a policy can be
quarantined for further review. Proofpoint's
Compliance Incident Manager™ interface makes it easy
for business users—such as compliance, security,
risk management, HR and other line-of-business
managers—to administer their own email and network
content security policies, review violations,
approve exceptions and monitor incidents through an
easy-to-use interface and email-based notification
system. The Compliance Incident Manager actively
notifies managers of policy violations and
associated severity levels, so they can easily and
effectively review non-compliant messages and
release, reroute, approve or otherwise manage
incidents using Proofpoint's graphical user
interface.
