Proactive Defense with Grey Wall Technology

Temporarily restrict access to suspicious domains for proactive protection.

Understanding Grey Wall: Securd's Proprietary DNS Defense Innovation


Grey Wall is Securd's cutting-edge, proprietary technology designed to defend organizations against asymmetric Internet threats. By creating a configurable barrier against low-trust domains, Grey Wall offers a proactive approach to cybersecurity, particularly effective during the critical "golden hour" of an attack.


Key Features of Grey Wall:


  1. Adaptive Learning: Analyzes your DNS traffic patterns to establish a baseline of normal activity

  2. Dynamic Trust Scoring: Assigns trust levels to domains and hostnames based on multiple factors

  3. Configurable Blocking: Allows customization of blocking duration from 5 minutes to 90+ days

  4. Zero Trust Approach: Assumes all new or unfamiliar domains are potentially risky


How Grey Wall Works: A Deep Dive into Proactive DNS Defense


  1. Traffic Analysis: Continuously monitors and learns from your organization's DNS queries

  2. Risk Assessment: Evaluates domains based on age, reputation, historical behavior, and current context

  3. Dynamic Blocking: Temporarily restricts access to suspicious or high-risk domains

  4. Adaptive Response: Adjusts trust levels and blocking durations based on ongoing analysis


Advanced Grey Wall Capabilities:


  • Machine Learning Integration: Enhances risk prediction accuracy over time

  • Threat Intelligence Correlation: Combines internal analysis with external threat feeds

  • Behavioral Anomaly Detection: Identifies unusual patterns in DNS query behavior

  • Granular Policy Controls: Allows customization of Grey Wall settings for different user groups or departments


Benefits of Implementing Grey Wall Technology


  1. Proactive Threat Prevention: Stop attacks before they start, without relying on Indicators of Compromise (IoCs)

  2. Reduced Attack Surface: Limit exposure to potentially malicious new or dormant domains

  3. Minimized Human Error: Protect against unwitting user interactions with high-risk domains

  4. Adaptive Security Posture: Automatically adjust defenses based on evolving threat landscapes

  5. Complementary Protection: Enhance existing security measures with an additional layer of DNS defense


Grey Wall in Action: Real-World Scenarios


  1. Phishing Campaign Defense:

    • Scenario: A new phishing domain is created to target your organization

    • Grey Wall Response: Automatically blocks access to the domain due to its lack of history and trust

  2. Zero-Day Exploit Mitigation:

    • Scenario: An attacker attempts to use a previously dormant domain for a zero-day exploit

    • Grey Wall Response: Temporarily blocks the suddenly active domain, preventing potential damage

  3. Botnet Command and Control Prevention:

    • Scenario: A botnet attempts to establish communication with a new C2 server

    • Grey Wall Response: Blocks DNS resolution to the unfamiliar domain, disrupting the botnet's operation


Implementing Grey Wall: Best Practices


To maximize the effectiveness of Grey Wall technology:

  1. Regularly review and adjust Grey Wall configurations to align with your risk tolerance

  2. Integrate Grey Wall alerts with your Security Information and Event Management (SIEM) system

  3. Conduct periodic assessments of Grey Wall's impact on legitimate business operations

  4. Educate users about the purpose of Grey Wall and how to report false positives

  5. Use Grey Wall insights to inform broader cybersecurity strategies and policies


Elevating Your Cybersecurity with Grey Wall Technology


In an era where cyber threats evolve at an unprecedented pace, Securd's Grey Wall technology stands as a powerful sentinel for your organization's DNS security. By providing:

  • Proactive defense against new and emerging threats

  • Adaptive protection that learns and evolves with your network

  • Reduced reliance on reactive security measures


Grey Wall empowers organizations to stay ahead of cybercriminals, offering a dynamic and intelligent approach to DNS security that addresses the challenges of today's complex threat landscape.Defend against asymmetric Internet threats targeting your organization and the golden hour of an attack. Our proprietary Grey Wall technology learns your DNS traffic and creates a configurable barrier low trust domains.


This innovative and powerful feature reduces cyber risk by limiting unwitting end-users from interacting with domains, hostnames with zero trust, history, and reputation. Apply a temporary block to new, dormant, and high-risk indicators from 5 mins to 90 days+ and stop attackers without the need for IoCs.
