Netmail Secure is email security for administrators who want to spend less time managing email. With easy-to-apply policies for attachment blocking, content filtering, and outbound limits, Netmail Secure protects organizations from both targeted attacks and unknown threats. Netmail Secure also reduces end-user complexity by providing easy-to-use email encryption software.
To respond to an ever-changing threat landscape, Netmail relies on a combination of advanced techniques including attachment blocking, malware analysis, and proactive virus detection to help organizations effectively detect and block targeted attacks, and quickly respond when a potential threat has been detected.
The Attachment Blocking feature of Netmail allows you to configure policies to block attachments by filename or Mime type to prevent new types of viruses or unwanted attachments from entering your system. Netmail also supports fingerprinting which prevents files from being sent through the system when their extension has been renamed.
Netmail inspects executable files by comparing its hashtag against a database of white- and blacklisted items. If it is found on the whitelist, the inspected file is considered clean and also flagged to be excluded from future scans. Once a threat is blocked, its fingerprint is sent to a live network system to ward off future attacks.
Netmail's scanning engines uses several types of detection signatures for detecting malicious objects (files, processes, URLs, etc.). These signatures also rely on heuristics and emulation to evaluate the scanned sample which enables Netmail to detect new, previously-unknown, variants. We also rely on Behavior-based Intrusion Detection (IDS) to analyze the pattern of email traffic on a network or activity on a system in an attempt to detect malicious activity.
Data Loss Prevention
Netmail's combination of outbound content filtering, anti-phishing technology, and advanced approval workflows ensure that your organization is protected from data loss, and allows you to confirm decisions to send encrypted messages, or make sure that DLP-flagged messages do not contravene your organization’s security policies.
Granular content filtering lets you quickly identify payment card data, debit and credit card numbers, Personally Identifiable Information (PII) and Protected Health Information (PHI) within email and email attachments. Several pre-defined dictionaries are also included with Netmail to help you quickly apply appropriate content filters.
Netmail's Anti-Phishing technology protects you from attempts to acquire passwords, banking data and other sensitive information by fake websites, masquerading as legitimate ones. Outbound limits and suspicious link filtering lets you monitor unusual email behavior and identify potentially-compromised email accounts.
Advanced Approval Workflows
With Netmail, you can let the software make all the decisions based on the policies you configured. You can assign Moderator privileges to users within your organization, which gives them permission to act as a Moderator and review outbound email messages before they're sent.
Netmail reduces end-user complexity by providing easy-to-use email encryption software and simple spam classification and filtering rules, and by giving end users the option of managing their own spam quarantines via a link in a daily email report or a direct URL.
Sending an encrypted email message is so completely transparent, your end users will think they are sending a regular email. Netmail eliminates the complexity traditionally associated with email encryption technologies, and makes it simple to use and transparent to both senders and recipients.
Netmail's filtering engine classifies each message in different categories: commercial emails and newsletters, social network notifications, virus, spam, and legitimate email. Based on its classification and the probability that a given message is spam, the engine determines the appropriate action, from tagging, rejecting, dropping, or routing the message.
With Netmail, end users can easily manage their own spam quarantines via an email report or URL link. Both ways feature single-click release, report, delete, allow, block, and more. You can even let your end users create their own allow/block lists to make sure the email they want is always delivered to their mailboxes.
Visibility & Flexibility
Netmail provides organizations with a rich set of policy options that allows you to fine-tune your security rules for full visibility and flexibility. From customizing policies based on domains, groups or individual users to detailed threat reports and message tracking, Netmail ensures better security and transparency for the entire organization.
With Netmail, all configuration settings are done through a single policy-based interface. It's so easy to create policy filters and then automatically apply them too different domains, groups or individual users to suit your organization's individual needs.
Detailed Threat Reports allow you to analyse inbound and outbound traffic to better understand the precise nature and threat level of traffic in your network. You can also customize these reports to see precisely how many email messages containing viruses, spam, blocked attachments, and other filtered email are being blocked.
Detailed Message Tracking
Netmail tracks all inbound and outbound messages, even if the messages are rejected. Simply use the Message Tracking feature to search by sender, recipient, subject, host, or date range criteria. Once you've obtained your search results, you can view detailed message tracking information about each individual message.
