Defend, Prevent, Encrypt, AnalyzeWhy purchase yet another point solution? Proofpoint's unified email security and data loss prevention platform provides comprehensive protection against both inbound threats and outbound content security risks–and Proofpoint's modular architecture lets you easily deploy new defenses as your needs change. All Proofpoint features–including anti-spam, anti-virus, anti-phishing, multi-protocol content security, policy-based encryption and reporting features–are managed centrally from a single administrative GUI and deployed on a unified appliance architecture. Features can be deployed in nearly any configuration, to meet your organization's unique requirements. Whether your deployment involves a single Proofpoint server or multiple, globally distributed appliances, all policy management and administration tasks are controlled via Proofpoint's centralized, web-based administration console. Defend Against Inbound ThreatsAdvanced Spam Detection, Powered by Proofpoint MLX™Powered by patent-pending Proofpoint MLX machine learning technology, the Proofpoint Spam Detection™ module examines hundreds of thousands of attributes in every email–including message envelope headers and structure, image properties, sender reputation data as well as unstructured content in the body of messages–to block the most spam, image-based spam and phishing attacks, while automatically adapting to new attacks as they appear. And the Proofpoint Dynamic Update Service™ automatically keeps your spam protection up-to-date, ensuring maximum effectiveness at all times. Individually controllable spam and adult content scores allow you to enforce zero-tolerance policies against pornographic spam. Anti-phishing features stop the spread of phish and other identity-theft attacks from stealing personal information from employees. Proofpoint Spam Detection is multi-lingual and offers outstanding accuracy against spam in any language–including hard-to-analyze, multi-byte character languages such as Japanese and Chinese. Anti-spam and anti-phishing policies can be customized at the global, group and end-user levels with full integration to LDAP or Active Directory to streamline ongoing administration. Integrated Email Firewall ProtectionThe Proofpoint Email Firewall™ provides a stateful, first line of defense against spam and malicious connections by testing numerous connection-level data points including DNS, MX record verification, SPF, recipient verification, Proofpoint Dynamic Reputation information and optional netMLX data. Innovative Connection ManagementProofpoint Dynamic Reputation™–powered by Proofpoint netMLX™–adds the industry's most powerful connection management features to your Proofpoint deployment. It's the only email reputation service that uses a combination of local, predictive behavioral data and globally-observed reputation–analyzed by powerful machine learning algorithms–to block incoming connections from malicious IP addresses. All Proofpoint appliances and software deployments provide built-in, predictive, behavioral analysis of local IP traffic that responds in real-time to eliminate email traffic spikes caused by target attacks and to block or throttle malicious connections from botnets. Customers with high email volumes can add the enhanced protection of Proofpoint netMLX to their deployments to reduce inbound connection volumes by a total of 80% or more. Proofpoint netMLX creates the industry's most accurate and up-to-date database of reputation for IP addresses sending email across the Internet. Each minute, hundreds of data points for all IP addresses are parsed with advanced machine learning algorithms to generate a score that represents the sender's reputation. Proofpoint Dynamic Reputation then uses these scores, combined with local behavioral data, to make intelligent decisions about accepting, throttling or rejecting incoming email connections. Virus Protection and Zero-Hour Anti-Virus DefensesThrough strategic partnerships with leading anti-virus vendors, Proofpoint Virus Protection™ provides complete virus scanning functionality. Virus engines are deeply integrated with Proofpoint's platform, providing convenient, centralized administration of anti-virus policies from the same interface used to manage spam and content policies. Messages are efficiently scanned for viruses in parallel with spam and message content, protecting end users from viruses, worms and other malicious code. Additionally, the Proofpoint Zero-Hour Anti-Virus™ module protects against emerging viruses in the earliest stages of their proliferation–stopping them hours before competing solutions even begin to react. Prevent Leaks of Information Across Multiple ProtocolsProofpoint's advanced data loss prevention features can protect outbound email as well as additional message streams including web-based email, blog postings, message board postings and other HTTP- or FTP-based activity. Content Compliance: Easily Enforce Acceptable Use PoliciesProofpoint Content Compliance™ makes it easy to define and enforce corporate acceptable use policies for message content and attachments. A convenient point-and-click interface simplifies the process of defining complex rules related to file types, message size, and message content. These features can be used to identify and prevent a wide variety of inbound and outbound policy violations–including offensive language, harassment, file sharing and violations of external regulations. Regulatory Compliance: Keep Private Data SecureMore than ever, enterprises need to safeguard the privacy and security of customer and employee data. The Proofpoint Regulatory Compliance™ module enforces best practices for securing private data and protects your organization from liabilities associated with privacy and data security regulations (such as HIPAA, GLBA, PCI, SEC rules and others). Customizable rules, managed dictionaries and "smart identifiers" are used to automatically scan for non-public information–such as protected health information and personal financial information–and reject or encrypt messages as appropriate. Proofpoint's smart identifiers are more sophisticated than simple regular expressions. They look for the correct number of digits or characters, but also perform complex algorithmic processing to ensure high detection accuracy while minimizing false positives. Digital Asset Security: Protect Confidential DocumentsAs email, webmail and other messaging systems have become the most important communication channels, they've also become a conduit for the exposure of sensitive or confidential information. The Proofpoint Digital Asset Security™ module keeps valuable corporate assets and confidential data from leaking outside your organization via email and other messaging protocols. Powerful MLX machine learning technology analyzes and classifies your confidential documents and then monitors for that information (or parts of that information) in the outbound message stream–stopping content security breaches before they happen. Encrypt Sensitive InformationProofpoint Secure Messaging™ adds powerful, content-aware encryption capabilities to your Proofpoint deployment, automatically encrypting messages based on your organization's policies. It automatically and consistently applies your encryption policies, without requiring end-users to take any special actions. Voltage IBE (identity based encryption) technology provides powerful, easy-to-use encryption without the key and certificate management hassles of other solutions. Proofpoint's hardware and virtual appliances also support digital certificates and enable gateway-to-gateway secure transfer and receipt of email using Transport Layer Security (TLS). Analyze Your Messaging InfrastructureProofpoint Smart Search™ enhances Proofpoint's built-in logging and reporting features with advanced message tracing, forensics and log analysis capabilities–offering easy, real-time visibility into message flows across your entire messaging infrastructure. Search and analyze all of your message logs from one convenient, easy-to-use GUI–even across globally distributed Proofpoint deployments.
