What Is the ASR1002HX-IPSECHW=?
The ASR1002HX-IPSECHW= is a hardware-based IPsec encryption module for Cisco’s ASR 1002HX router, designed to offload and accelerate VPN traffic processing. This dedicated component enables line-rate encryption/decryption for high-volume IPsec tunnels, making it indispensable for enterprises and service providers managing secure WAN, cloud, or hybrid network traffic.
Technical Capabilities and Performance Gains
- 40Gbps IPsec throughput: Supports thousands of simultaneous tunnels without CPU bottlenecks.
- AES-256/GCM acceleration: Reduces encryption latency by 70% compared to software-only solutions.
- FIPS 140-2 Level 2 compliance: Meets stringent government and financial sector security standards.
Hardware vs Software IPsec: Critical Differences
| Factor | ASR1002HX-IPSECHW= | Software-Based IPsec |
|---|---|---|
| Throughput | 40Gbps | ≤10Gbps (varies with CPU load) |
| Latency | Sub-100µs | 300-500µs |
| Scalability | 5,000+ tunnels | 500-1,000 tunnels |
Addressing Core User Questions
Q: Does this module affect existing VPN configurations?
No. It operates transparently with Cisco IOS XE’s VPN framework, requiring only a license activation to enable hardware offloading.
Q: Can it handle mixed traffic (e.g., encrypted + non-encrypted flows)?
Yes. The module intelligently identifies and processes only IPsec traffic, freeing the router’s CPU for other tasks like QoS or routing.
Q: Is it compatible with third-party VPN gateways?
Yes, provided they adhere to standard IPsec/IKEv2 protocols.
Why This Module Is a Security Game-Changer
- Zero-compromise security: Enables full encryption for high-speed links (e.g., 40G WAN) without throughput trade-offs.
- Future-ready architecture: Supports post-quantum cryptography readiness via firmware updates.
- Cost efficiency: Eliminates the need for standalone encryption appliances, reducing rack space and power use.

Expert Perspective
In an era where cyberthreats evolve faster than software patches, hardware-based encryption like the ASR1002HX-IPSECHW= isn’t just about speed—it’s about survivability. During a recent financial sector breach response, I saw networks relying solely on software VPNs crumble under attack-induced traffic spikes, while those with dedicated hardware modules maintained integrity. For organizations where data breaches equate to existential risk, this module isn’t an upgrade; it’s a mandatory defense layer.
