Myra DDoS Protection

Myra DDoS Protection is a SaaS solution that helps organizations defend their websites, web applications, and APIs against application-layer (Layer 7) DDoS attacks that target existing connections and seek to overload web servers with seemingly legitimate requests. Myra DDoS Protection works as an upstream reverse proxy, blocking harmful traffic flows through multi-level filter layers while allowing valid requests to continue reaching the origin infrastructure as usual. The solution requires no additional hardware or software – setup is handled either by adjusting a DNS CNAME record or through automated integration via the Myra API. It is part of the broader Myra Application Security suite and can be extended with additional security products as needed. The solution is designed for organizations in regulated industries such as finance, healthcare, e-commerce, and public sector, as well as operators of critical infrastructure (KRITIS) that require certified, compliance-ready protection for their web-facing assets. Key features and capabilities include: - Automated Layer 7 Attack Mitigation: Myra's automated defenses take effect in under one second, and on average block over 8 million malicious Layer 7 requests per customer annually. - Deep Packet Inspection: By uploading SSL/TLS certificates, Myra can terminate TLS connections and inspect traffic at a deep packet level, enabling granular filtering of malicious application-layer requests. - Customizable Filtering Rules: Myra's Security Operations Center (SOC) works with customers to configure multi-layer filtering rules and custom security settings tailored to their specific environment and traffic patterns. - GeoIP-Based Traffic Controls: Suspicious clients can be blocked or rate-limited based on geographic origin, giving teams fine-grained control over incoming traffic without impacting legitimate users. - Compliance & Certification: Myra holds ISO 27001 certification based on BSI IT-Grundschutz, BSI C5 Type 2, BSI KRITIS qualification, PCI-DSS, IDW PS 951 Type 2, ISO 9001 and supports compliance with NIS-2, DORA, and GDPR requirements. Myra guarantees service availability of up to 99.9% via SLA, backed by 24/7 monitoring and automated attack notifications. The platform provides complete traffic visibility to support smart load balancing and reliable failover, ensuring web applications remain accessible even during sustained application-layer attacks.

RioRey DDoS Protection Platform

The RioRey DDoS Protection Platform is a network-security solution that detects and mitigates Distributed Denial of Service (DDoS) attacks for Internet service providers, hosting companies, and enterprise networks. It is designed to provide high-capacity, automated defense across on-premise, virtual, and cloud-scrubbing deployments. At the core of the platform is RIOS, RioRey’s proprietary filtering software that analyzes packet behavior in real time to identify and block malicious traffic while preserving legitimate flows. RIOS can be delivered as a hardware appliance for line-rate throughput, as a virtual machine for flexible subscription deployment, or through rCloud, RioRey’s cloud-based scrubbing service. All deployments are managed through rWeb, a unified management and analytics console included with every license. Optional Director modules extend visibility by ingesting NetFlow data to support large multi-site environments. Architecture and Function: Our platform applies algorithmic detection that focuses on underlying attack methodology rather than relying on signatures, threat feeds, or baselines. This approach allows the system to recognize and mitigate all 25 known DDoS attack classes—volumetric, state-exhaustion, protocol, and application-layer—without continuous manual tuning. RioRey’s algorithms operate deterministically, ensuring predictable behavior and low false-positive rates even under extreme load conditions. Key Features: - Unified Management: rWeb provides centralized control, alerting, and reporting for all devices and tenants from a single interface. - Multi-Tenant Operation: Designed for service-provider environments, the platform supports segregated customer policies, reporting, and branding. - Flexible Deployment: Available as on-prem appliance, VM image, or cloud-scrubbing service to match operational and financial preferences. - Low Operational Overhead: Automated mitigation and policy inheritance minimize the need for manual intervention or frequent updates. - Hybrid Scalability: On-prem filtering integrates directly with rCloud scrubbing for overflow events or large-scale volumetric attacks. Use Cases: ISPs and Hosting Providers: Deliver managed DDoS protection to downstream customers while retaining visibility and control. Enterprises and Financial Institutions: Protect critical online applications and infrastructure without adding staff burden. Education and Public Sector Networks: Maintain uptime and service availability during peak traffic events or targeted attacks. Value Proposition: The RioRey DDoS Protection Platform enables organizations to deploy carrier-grade mitigation capacity with predictable performance and minimal operational complexity. By combining algorithmic detection, unified management, and multiple delivery models, it allows network operators to tailor protection to their topology and business model. Customers can start with a single appliance or VM and expand to hybrid or cloud configurations as requirements grow,all under one management framework.
