What is Email Security?

Email security refers to the methods and techniques used to protect email communication from unauthorized access, interception, and other security threats like phishing, malware, and ransomware. It encompasses various strategies, including encryption, authentication, and access controls, aimed at securing both the sending and receiving of email messages.

Why Do You Need Secure Email?

In today's landscape, secure email is critical because emails are often the first line of attack for cybercriminals. Phishing attacks, ransomware, and stolen credentials commonly originate through email. With the rise of remote work and cloud adoption, traditional email security models have become inadequate in safeguarding against these evolving threats.

Email Security Challenges:

• Phishing Attacks: Fraudulent emails designed to steal sensitive information or install malicious software.
• Ransomware: Malicious emails with attachments that encrypt data, holding it hostage for ransom.
• Compromised Credentials: Emails with links to fake login pages that trick users into disclosing passwords.
• Remote Work & Hybrid Environments: The expansion of remote access increases the risk of unauthorized email access.

Traditional Approach to Email Security

The traditional way of securing email typically involves:

• Public IPs: Email servers are connected to the public internet, making them more vulnerable to attack.
• Basic Firewalls: Designed to block unauthorized access but not sophisticated phishing or malware attacks.
• Antivirus & Spam Filters: Detect and block known malware and suspicious emails, but are ineffective against zero-day threats.
• User Training: Relying on educating users to recognize phishing attempts, which is often not enough to stop advanced attacks.

Gopher Email: Innovative Email Security Approach vs. Traditional Approaches

By implementing role/group-based access control, Gopher Email ensures employees have access only to the emails and resources they need, reducing the risk of internal threats and data breaches.

5/ Attribute-Based Access Control for Dynamic Requirements

Traditional Email Security:
Traditional systems lack dynamic controls for access, offering rigid security policies that do not accommodate temporary or conditional access needs.

Gopher Email:
Gopher Email supports attribute-based access control (ABAC), allowing email administrators to define access based on various conditions such as time-bound access for contractors, location, device type, or identity match.

Customer Value:
With ABAC, businesses can ensure that access is granted only under specific conditions, offering flexibility while maintaining security.

6/ Context-Aware Endpoints Authentication

Traditional Email Security:
Basic username-password authentication methods are prone to phishing and are often the weakest point in traditional email security.

Gopher Email:
Gopher Email enforces context-aware authentication, verifying the user’s identity based on contextual factors like IP address, device fingerprint, and location. Even if credentials are compromised, unauthorized access is blocked.
