Protect SaaS, IaaS, and PaaS workloads with DNS-layer security spanning 90 million domains. Detect shadow IT, enforce cloud access policies, and safeguard API gateways across every cloud provider.
Traditional perimeter security cannot keep pace with dynamic cloud architectures. DNS filtering operates at the foundational layer of every network request, giving you visibility and control across all cloud services.
Employees adopt unapproved SaaS tools daily. DNS filtering identifies and categorizes unauthorized cloud services before they become data leakage vectors or compliance violations.
Organizations running workloads across AWS, Azure, and GCP face fragmented security postures. A unified DNS filtering layer provides consistent policy enforcement regardless of provider.
Microservices communicate via thousands of API endpoints. DNS filtering prevents compromised services from reaching restricted servers or exfiltrating data to malicious domains.
Address the unique vulnerabilities of cloud-native architectures at the DNS resolution layer
Over 80% of enterprises have unapproved cloud applications in use. Our DNS filtering engine detects requests to uncategorized SaaS platforms and flags them instantly, giving IT teams full visibility into unauthorized service adoption.
Cloud workloads in development, staging, and production environments need distinct DNS policies. Enforce granular filtering rules per environment to prevent lateral movement and contain content risks within isolated segments.
DNS tunneling and exfiltration over DNS remain among the most difficult attack vectors to detect. Our analysis of 90 million domains identifies suspicious DNS patterns that signal data theft attempts from cloud infrastructure.
restricted domains targeting cloud service login pages are a primary attack vector. DNS filtering blocks access to look-alike domains mimicking AWS Console, Azure Portal, and other cloud management interfaces before credentials are exposed.
Multi-region cloud deployments must comply with GDPR, SOC 2, ISO 27001, and regional data sovereignty laws. DNS filtering enforces jurisdiction-aware access policies ensuring data never routes through non-compliant services.
Ephemeral containers and serverless functions create thousands of short-lived DNS queries. Our filtering engine handles burst traffic patterns inherent to containerized deployments without adding latency to function execution.
Purpose-built features for securing modern cloud architectures at the DNS resolution layer
Create isolated filtering policies per cloud tenant, business unit, or customer environment. Each tenant inherits base security rules while maintaining the flexibility to customize category restrictions.
Continuously monitor DNS traffic to identify every cloud application in use across your organization. Categorize discovered services by category level, data sensitivity, and compliance status.
Deploy DNS filtering through our RESTful API that integrates with Terraform, CloudFormation, and Kubernetes manifests. Automate policy deployment as part of your CI/CD pipeline.
Gain deep visibility into DNS resolution patterns across cloud workloads. Identify bandwidth hogs, detect anomalous query volumes, and track cloud service adoption trends over time.
Leverage continuously updated content classification covering unsafe content C2 domains, restricted content infrastructure, and cryptojacking pools targeting cloud resources. block restricted content before the first packet is sent.
Seamlessly extend DNS filtering across on-premises data centers, private clouds, and public cloud environments. Unified policy management ensures consistent protection everywhere.
Real-world scenarios where DNS-layer filtering secures cloud operations
A multinational enterprise discovered 340 unapproved SaaS applications through DNS query analysis. By implementing category-based filtering policies, they reduced shadow IT exposure by 92% within 60 days while maintaining employee productivity.
An organization operating across three major cloud providers deployed DNS filtering as a unified security layer. Consistent domain-level policies eliminated the need for provider-specific security tools, reducing management overhead by 65%.
A software company integrated DNS filtering into their build pipelines to prevent dependency confusion attacks. Filtering blocked resolution of typosquatted package registry domains, stopping supply chain compromises before code execution.
DevOps teams applied DNS filtering at the cluster level to restrict pod-to-pod communication and external DNS resolution. This prevented compromised containers from reaching attacker infrastructure while allowing approved service mesh traffic.
During a data center to cloud migration, DNS filtering provided real-time visibility into which applications had been successfully migrated and which still communicated with legacy on-premises domains, ensuring a controlled transition.
A fintech company applied DNS filtering to Lambda and Cloud Functions to ensure serverless workloads only communicated with whitelisted financial APIs and data sources, preventing accidental data leakage to unauthorized endpoints.
