With Cisco CPAR reaching end-of-life, telecom operators and ISPs need a proven Cisco CPAR replacement. Alepo AAA Server is a carrier-grade platform built specifically for service providers, enabling seamless CPAR migration without disrupting existing network operations.
Authentication is the invisible backbone of every subscriber session. Broadband sign-ins, Wi-Fi access, and mobile data all depend on AAA (Authentication, Authorization, and Accounting): validating credentials, enforcing access policies, and generating session records for billing and analytics. For years, many operators relied on Cisco’s Prime Access Registrar (CPAR) to deliver this.
Now, with CPAR end-of-life, a modern replacement is essential.
What is Cisco CPAR and Why It’s Being Replaced
Cisco has officially declared CPAR end-of-life (EOL), with key milestones marking its retirement:
- April 30, 2023 — Cisco stopped selling CPAR
- October 28, 2024 — End of software maintenance and updates
- October 31, 2025 — End of all vendor support (Source: Cisco Official Announcement)
Operating beyond this point means no security patches, no updates, and growing compatibility risks with modern network components. For operators still running CPAR, the risks compound over time, making CPAR migration a strategic priority, not just a technical one.
Why Modern Networks Need a Better AAA Platform
The case for a legacy AAA replacement goes beyond lifecycle deadlines. Today’s telecom networks require:
- High-throughput authentication — processing thousands of requests per second across large subscriber bases
- Seamless integration — with policy control platforms (PCRF/PCF), subscriber databases (HSS/HLR), and charging systems
- Scalability — to support network growth without performance trade-offs
- Cloud-native architecture — to enable flexible, future-proof deployments
For service providers, this CPAR migration is not just a compliance necessity, it’s an opportunity to modernize authentication infrastructure for next-generation broadband, Wi-Fi, and mobile networks.

Multi-Protocol Support
Alepo AAA provides dual-stack support for RADIUS and Diameter, ensuring smooth integration across various networks and access technologies. REST/SOAP interfaces support both real-time and batch provisioning for IT systems, making it a true Cisco PAR alternative for converged networks.
Session Management
Zero-leakage session management handles multiple simultaneous sessions, allows mid-session policy changes, performs ghost session clean-up, and provides detailed real-time session visibility, enabling real-time prepaid enforcement with no revenue loss.
High Performance and Failover Support
A highly responsive system with 99.999% availability assures carrier-grade performance as the network grows and expands, ensuring your CPAR replacement never becomes a bottleneck.
Multi-Service Support
Supports all access technologies, broadband, Wi-Fi, and mobile, allowing operators to streamline operations, reduce total cost of ownership, and deliver convergent services with a single platform.
Noise Reduction
Reduces signaling “noise” caused by endless loops of authentication requests by redirecting problem users and instructing them to take corrective action, keeping network performance high and operational costs low.

FAQs
What replaces Cisco CPAR?
Alepo AAA Server is a leading Cisco CPAR replacement, widely adopted by telecom operators for its carrier-grade performance, scalability, and multi-protocol support. It supports RADIUS, Diameter, and REST/SOAP interfaces across broadband, Wi-Fi, and mobile networks.
What happens if we continue using Cisco CPAR after end-of-life?
Continuing beyond October 31, 2025, means operating without security patches, software updates, or vendor support, introducing compliance risks, security vulnerabilities, and growing incompatibility with modern network components.
Is Alepo AAA backward-compatible with existing CPAR configurations?
Yes. Alepo AAA supports standard AAA protocols and integrates with existing network infrastructure. Alepo’s migration team works with operators to map existing CPAR policies and configurations to the new platform during transition.
How long does migrating from Cisco CPAR to Alepo AAA take?
Timelines depend on network complexity and subscriber scale. Alepo follows a phased CPAR migration approach with dedicated expert support to minimize downtime and maintain service continuity throughout.
Does Alepo offer professional migration support?
Yes. Alepo provides end-to-end migration services from planning and integration to testing and go-live, ensuring a smooth and low-risk transition from legacy AAA systems.
