Securd: Advanced Anti-Phishing Protection with Intelligent DNS Security

In the ever-evolving landscape of cyber threats, phishing attacks remain one of the most pervasive and damaging risks to organizations. Securd offers a sophisticated DNS security solution with features specifically designed to combat phishing attempts. Let's explore how our key technologies work together to create a robust anti-phishing defense.


Core Anti-Phishing Technologies

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:

  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
