The Market Guide defines email security market challenges, outlines attributes of Representative Vendors, and provides recommendations for security leaders that are responsible for email security. On September 8 2020, Gartner released their latest ‘ Market Guide for Email Security’, a research document derived from more than 1,300 Gartner client interactions between June 2019 and June 2020. The targeted nature of email attacks coupled with the migration to cloud email have driven organizations to reevaluate their email security controls and processes. Then it applies the appropriate security remediation according to the specific regulation standards.Note: You can read the 2021 Gartner Market Guide for Email Security here.Įmail security has been in a state of transformation for a few years now. The Secure Email Gateway enables compliance with regulations (GDPR, HIPAA, etc.) – detects, protects, and audits emails, and attachments to validate sensitive data. Sanitization can take the form of automatic redaction of text with message bodies and attachments including images (such as screen shots) using OCR technology, or document sanitization which can remove hidden metadata, revision information, and auto-saved data associated with documents and images. The understanding of the content and the context is then applied into configured policies to determine if the message should be rejected, held, delivered, delivered encrypted, or sanitized in some way prior to delivery. Metadata can include document classification tags from Titus and Boldon James solutions which can signify whether the content is unclassified, classified, or even top secret. This way, they can be scanned for critical information like intellectual property, employee’s personal information, or forgotten content like metadata, revision history, or customer data. It is imperative that a thorough understanding of the message is performed by the deep content inspection capabilities in order to understand the email body, subject lines, and attachments (such as PDFs, Word documents, and images). Depending on your business, you might need to control the content of what’s being received by your employees. This provides a highly accurate and flexible approach where messages can be blocked, held, or delivered with warnings - all based on policy.ĭata Loss Prevention ( DLP) is not just an outbound problem. Spam and phishing emails are dealt with by a multi-engine, multi-layered spam filtration system, incorporating Signature Engines with machine learning, DMARC, DKIM, SPF, IP Reputation, Greylisting and URL analysis.
Malicious URLs in messages and attachments can be checked using several threat feeds, which can cause the message to be blocked, the URL to be sanitized, or the URL be rewritten so that if the link is clicked the URL will be processed by a Browser Isolation solution.
