Cilium vs Cloudflare Spectrum: What are the differences?
What is Cilium? API-aware networking and security for containers. Open source software for providing and transparently securing network connectivity and loadbalancing between application workloads such as application containers or processes.
What is Cloudflare Spectrum? DDoS protection for TCP services. Extend the power of Cloudflare's DDoS, TLS, and IP Firewall to not just your web servers, but also your other TCP-based services, keeping them online and secure. Reduce the ability for attackers to snoop and steal sensitive data. Protect your origin and all TCP services you expose to the Internet.
Cilium and Cloudflare Spectrum belong to "Security" category of the tech stack.
Some of the features offered by Cilium are:
- Identity Based Security - Cilium visibility and security policies are based on the container orchestrator identity (e.g., Kubernetes labels). Never again worry about network subnets or container IP addresses when writing security policies, auditing, or troubleshooting.
- Blazing Performance - BPF is the underlying Linux superpower to do the heavy lifting on the datapath by providing sandboxed programmability of the Linux kernel with incredible performance.
- API-Protocol Visibility + Security - Traditional firewalls only see and filter packets based on network headers like IP address and ports. Cilium can do this as well, but also understands and filters the individual HTTP, gRPC, and Kafka requests that stitch microservices together.
On the other hand, Cloudflare Spectrum provides the following key features:
- DDoS Protection for TCP Services - ensures all your TCP services are protected against Layer 3 and 4 DDoS attacks, remaining online and performant
- Secure TCP traffic with TLS - encrypts services running on TCP to prevent unencrypted data, such as user credentials, from falling into the wrong hands
- IP Address & Range Blocking - integrates with Cloudflare’s IP Firewall, allowing you to block or challenge IP addresses or entire IP ranges from reaching your TCP services
