According to the SANS Institute, email attacks are increasing dramatically, with spear phishing now one of the most common types, right along with ransomware. In the case of spear phishing attacks, cyber criminals carry out extensive social engineering activities to gather personal information and craft messages that appear from trusted sources to gain the victim’s confidence.
The Problem
It is becoming increasingly difficult to accurately detect all bad emails, especially those containing attachments, without slowing down email to such an extent that it impacts employee productivity. In many cases, critical business communications need to be delivered promptly, without any delay or being lost in junk or spam folders. In addition, traditional signature-based technologies are proving to be ineffective in stopping phishing emails that contain malicious payloads such as ransomware.
Traditional email security solutions rely on static IP reputations and signature-based detection mechanisms, which simply cannot protect against today’s evasive and sophisticated malware. Detection alone does not suffice and often notifications are useless in stopping an ongoing attack.
All this points to the need for email security solutions that move beyond detection to prevention and have the ability to stop attacks before they even reach your network. To accomplish this, email security must employ a multi-layered approach.
The Solution
SonicWall’s next-gen email security solution uses a multi-layer defense approach with a sandbox technology called Capture Advanced Threat Protection (ATP). To stop potentially malicious emails from entering your network, they are first sent to the cloud for analysis and held at the gateway until a verdict is applied, thus protecting your business against phishing, spoofing and spam.
Here are some of the email protection capabilities included with Capture ATP:
- Scans all SMTP traffic and email attachments
- Offers encryption and data leakage prevention for outbound protection
- Features anti-spoofing authentication mechanisms such as DKIM, SPF and DMARC, to protect against impostor emails
- Provides granular policy settings such as “Tag a subject line” or “Strip email attachment”
