DNS Guardian Adaptive DNS security to ensure service continuity and data protection DNS Guardian is a protective DNS service that brings unique DNS security features to overcome the limitations of firewalls and IPS. DNS Guardian Key Benefits The most advanced DNS security solution on the market to protect users, apps, and data against attacks such as cache poisoning, DDoS, and data exfiltration. Behavioral Threat Detection Real-time DNS analytics accurately detect the most sophisticated stealth attacks and threats hidden in the traffic. Unequaled Service Continuity Even with unidentifiable sources, via adaptive countermeasures (Block, patented quarantine, and recovery modes). Predictive Network Security Detect zero-day malicious domains used by malware to exfiltrate data or communicate with external CnC servers via DNS tunneling. Data Confidentiality Protection Sensitive data protected from exfiltration- assured regulation compliance: GDPR, US Cloud Act, NISD, PDPA... Improved App Access Control Combining DNS Filtering with Allow/Deny lists enables granular control of which users are allowed to access which specific apps. "Prevent the spread of attacks by making DNS your first line of defense." Romain Fouchereau, IDC Security Analyst - IDC 2022 Global DNS Threat Report Purpose-Built Security Solution to Secure DNS Services Signature-based security solutions like firewalls, anti-DoS, or IPS are not adapted to efficiently ensure DNS services availability and integrity. They have proved insufficient against most DNS attacks - DNS hijacking, amplification and reflection attacks, and DNS flooding...even worse, present a high risk of blocking legitimate clients (false positives). Restricted DNS analytics capacity and basic blocking-based countermeasures imply serious network security limitations and risks: Business downtime, data theft, brand damage, and embezzlement of money. EfficientIP DNS Security solutions provide agility to adapt DNS protection mechanisms to mitigate the risk of false positives while safeguarding data and ensuring DNS service integrity and continuity to legitimate clients. Spot DNS Attacks with Behavioral Threat Detection DNS Guardian delivers built-in security to cache, recursive, and authoritative DNS servers. It is the premier secure DNS appliance on the market offering complete and real-time DNS Transaction Inspection (DTI), enabling an in-depth understanding of the context of client requests. By analyzing transactions at the heart of the DNS server (queries, responses, fragments, recursions), threat visibility is enhanced well beyond known attack patterns and overcomes the limitations of signature-based protection systems that only offer limited peripheral traffic visibility. Protect DNS Service Continuity and Data with Adaptive DNS Security DNS Guardian’s patented innovation enables graduated and adaptive countermeasures according to the threat analysis. It provides intelligent DNS protection to ensure service continuity and safeguard data while nearly eliminating all risks of false positives. The product offers the most advanced DNS security solution on the market to protect against all types of DNS-based attacks, from stealth to volumetric attacks. including cache poisoning, DDoS attacks, DNS tunneling, DGA malware, and UDP flood.

Get Started Thwart Malware & APT with External and Internal Threat Intelligence Services Almost 100% of network connections are initiated using DNS services. Analyzing DNS traffic to develop internal threat intelligence in the specific context of the enterprise is a key security component of modern network security strategy. DNS Guardian together with a specialized feed such as DNS Threat Pulse offers a unique capability to detect zero-day malicious domains used by malware to communicate with external CnC servers (DNS tunneling) or exfiltrate data, and DGAs (domain generation algorithms). Identified malicious domains are dynamically shared between DNS Guardian appliances, delivering actionable predictive DNS security. This complements EfficientIP or third party threat intelligence services over domain reputation. Enhance Threat Remediation and SOC Efficiency Get instantaneous visibility on DNS services to improve remediation capacity with out-of-the-box statistics, delivering unequaled insights and reports on DNS traffic, without the need for additional appliances. DNS Guardian delivers high-performing logging capabilities which can be seamlessly integrated with leading SIEM solutions such as Kibana, Splunk, or QRadar. Events resulting from the analysis of DNS transactions, together with threat intelligence over domain reputation, are used to supplement traditional logs, allowing the SIEM to contextualize the threat, and aid NetSecOps. Improve App Access Control at Individual Client Level The DNS Guardian engine implements application access control at the DNS level through DNS filtering, via the Client Query Filtering (CQF) feature. This unique proposition on the market offers scalability and performance for a host of network security use cases ranging from IoT segmentation to parental control.
