Spam Filtering and Email Encryption

Spam accounts for 70% of email messages. Over 3% of emails have malicious attachments. 91% of successful hacks begin with email attacks. It all adds up to the urgency of protecting your email.

Progent has partnered with leading IT security companies to offer small and mid-size businesses ProSight Email Guard, a hybrid security solution that uses cloud-based resources and on-premises security gateway hardware to provide multi-tiered defense against spam, email-borne viruses, Denial of Service (DoS) attacks and other email-based threats. In addition, ProSight Email Guard's security gateway hardware provides outbound email encryption, enforces your internal content policies to keep sensitive data from leaking outside of your organization, and helps keep your organization off spam block lists by filtering outbound spam and viruses.

Progent's email security consultants can assist you to design and implement your ProSight Email Guard deployment, help you determine which email security gateway appliances are the best fit for your needs, configure your gateway, integrate ProSight Email Guard with Microsoft Exchange Server or any other email platform, set up policies for filtering inbound and outbound email, configure outbound encryption, plan and deploy high-availability topology that can include clustered security gateways, set up a streamlined cloud-based management system that utilizes delegated administration, and provide training, ongoing consulting support and troubleshooting.

Key Features of ProSight Email Guard
ProSight Email Guard is a complete solution for protecting inbound and outbound email. ProSight Email Guard offers these key features:

• Spam Protection uses heuristic-rules that analyze IP addresses, message content, and even images/
• Zero-hour Virus Protection offers multi-tiered scanning and 24x7 real-time updates
• Cloud-based Pre-filtering prevents the vast majority of email threats from ever reaching your security perimeter
• On-premises Gateway Appliance is purpose-built for deep analysis of inbound and outbound traffic
• Cloud-based Management with delegated administration rights centralizes and simplifies policy and configuration control
• Outbound Filtering provides policy-based Content Filtering for Data Loss Prevention (DLP) and Data Leakage Protection and blocks outbound spam and viruses
• Encryption uses AES with 256-bit keys and automatically protects outbound email that meets your policy settings
• Rate Control blocks spambots and controls outbound email rate based on IP address or sender's email address
• Denial of Service (DoS) Attack Protection keeps your network from being disabled by an overload of malicious spam
• Directory Harvest Attack (DHA) protection keeps spammers from stealing and selling your users' email addresses
• Low False Positive Rate is an industry-leading 0.01% before you apply any of the available custom optimization options
• Internal Email Protection with Exchange protects email that stays within your security perimeter, never reaching your gateway

The reliability of your email system is also improved due to the hardened, geographically dispersed data centers behind Email Guard's cloud infrastructure. Data center uptime averages 99.999 percent, far higher than can be achieved by the email servers of most small or mid-size businesses. If your email server or internal network infrastructure fails, Progent's Microsoft-certified consultants and Cisco-certified network engineers can provide immediate online expertise to get you up and running quickly.

Inbound Email Protection
All inbound email secured by ProSight Email Guard passes through the Cloud Protection Layer, which uses advanced data centers and massive computing grids to block 95% of spam and most email carrying viruses and other malware. Email that clears this first level of filtering is subjected to deep analysis by purpose-built on-premises security gateway hardware that provides multi-level inspection including OCR technology to detect image spam. The Cloud Protection layer and the email security gateway are continually updated in real time by the cloud-based Update Center, a technology center staffed 24x7x365 by security experts to provide zero-hour protection against the latest threats without requiring the intervention of your management personnel. For disaster recovery, the Cloud Protection Layer offers email spooling, which can store all your inbound email for up to 96 hours or redirect it to an alternate destination in case your on-premises data center is disrupted.

Outbound Email Protection
The outbound filtering capability of ProSight Email Guard prevents costly data leaks and protects your reputation as a trusted source of email. ProSight Email Guard provides Data Loss Protection (DLP) through policy-based content filtering. This prevents users from inadvertently releasing valuable or private information through email messages. Leaked information can violate regulatory requirements and can result in loss of competitive advantage, identity theft, and even litigation. The ProSight Email Guard security gateway appliance comes with standard content filters that include HIPAA, Social Security Numbers, credit card numbers. In addition, you can define custom policies for filtering content based on keywords, categories, or other factors. ProSight Email Guard allows you to use content filtering policies for automatically blocking, quarantining or encrypting email messages.

Outbound filtering can also block spam and viruses sent by internal computers that have been compromised, which is a serious vulnerability in BYOD (Bring Your Own Device) environments. Organizations which allow spam and viruses to be sent out can be placed on block lists, or "blacklisted". This loss of reputation can hurt productivity and profits.

Outbound Email Encryption
ProSight Email Guard uses a cloud-based Message Center to encrypt and deliver outbound email. You can configure multiple policies for deciding which emails should be encrypted, and the entire process is handled automatically. The on-premises security gateway sends email to be encrypted to the Message Center using a secure TLS connection. There the messages are encrypted using the advanced AES-256 standard and stored for retrieval. The Message Center sends a notice to the recipient and includes a web link that permits the recipient to retrieve the decrypted email. Any replies are also encrypted at the Message Center.

A plug-in for Microsoft Exchange allows users to encrypt emails on an individual basis. For additional details about ProSight Email Guard outbound email encryption, see Email Guard technology and architecture.
