The Securd Greywall: Proactive Defense Against New Threats

​

The Greywall is our proprietary technology that significantly reduces the risk of phishing attacks by temporarily limiting interactions with potentially dangerous domains. Here's how it works:

• Zero-History Domain Detection: Identifies and restricts access to newly registered domains, a common tactic in phishing campaigns.

• Reputation Analysis: Evaluates domain reputation in real-time, blocking those with suspicious characteristics.

• Algorithm-Generated Domain Protection: Detects and prevents access to domains likely created by automated systems for malicious purposes.

 

Real-World Scenario: Greywall in Action

​

1. Phishing Attempt Initiation:

   • A threat actor registers a new domain and launches a phishing campaign within 15 minutes.

   • An unsuspecting user clicks on a phishing link: https://some-evil-phishing-site.example.com/phishing-attack/login.html

2. Securd Intervention:

   • As the user's system attempts to resolve the domain, Securd's Greywall intercepts the request.

   • The Greywall checks if the domain has been observed before and evaluates its characteristics.

   • If suspicious, access is denied, and the user is redirected to a block page explaining the reason.

3. Ongoing Protection:

   • The blocked attempt is logged for security admin review.

   • Even after the initial Greywall period expires, Securd continues to monitor the domain for threats.

 

Domain Rank: Intelligent Threat Assessment

​

Our Domain Rank system complements the Greywall by:

• Assessing the reputation and risk level of domains in real-time

• Utilizing machine learning to identify patterns associated with phishing domains

• Continuously updating risk scores based on global threat intelligence

 

Custom Block Lists and Security Policies

​

Tailor your protection against known and emerging phishing threats:

• Create and manage custom blocklists for identified phishing domains

• Implement granular security policies based on your organization's risk profile

• Quickly respond to new phishing campaigns by updating policies in real-time

 

DNS over TLS (DoT) and DNS-over-HTTPS (DoH)

​

Protect against sophisticated phishing attacks that exploit DNS vulnerabilities:

• Encrypt DNS queries to prevent eavesdropping and man-in-the-middle attacks

• Thwart attempts to redirect users to phishing sites through DNS manipulation

 

Comprehensive Logging and Analysis

​

Gain crucial insights into phishing attempts:

• Detailed logs of all DNS queries, including blocked phishing attempts

• Real-time log forwarding to your SIEM or analysis tools for immediate threat detection

• PagerDuty integration for instant alerts on suspected phishing activities
