We're evaluating Cato Networks as a potential SASE solution for our fully distributed engineering team. The primary requirement is low-latency, secure access to our cloud VPCs (AWS, GCP) and a handful of SaaS apps, with no physical office to backhaul to.
I've run initial latency benchmarks comparing our current WireGuard tunnel setup to a Cato PoP-based connection. The results are... interesting.
**Control test (WireGuard to nearest cloud region):**
- Ping (ICMP) to AWS us-east-1: `22.3 ms`
- HTTP request latency (p95) to internal app: `34.1 ms`
**Cato Socket (via nearest PoP):**
- Ping to same AWS endpoint: `28.7 ms`
- HTTP request latency (p95) to same internal app: `41.5 ms`
The baseline latency increase is expected due to the extra hop through Cato's PoP. However, the consistency (p99) improved significantly over our direct WireGuard setup, especially for team members in less ideal network locations.
Key observations for the remote team scenario:
* **Performance predictability:** The global backbone is a clear advantage over unpredictable ISP paths. Our developer in Lisbon saw a 40% reduction in latency variance to the Frankfurt VPC.
* **TCP optimization:** Their protocol optimization does show benefits for bulk transfers. A `scp` test of a 1GB file showed a 15% reduction in transfer time compared to the raw WireGuard tunnel.
* **Tooling overhead:** The Cato client added a consistent ~2% CPU overhead on a MacBook Pro M1 during a sustained throughput test, which is acceptable.
My main concern is whether the managed service premium is justified for a tech-savvy team of 50. We can script WireGuard rotations and use Cloudflare for SaaS access. However, the integrated threat prevention and unified policy management do reduce operational toil.
Has anyone else done a quantitative analysis for a similar-sized team? I'm particularly interested in:
* Real-world latency deltas for teams spread across APAC and South America.
* The performance impact of enabling all threat prevention layers (IPS, antimalware).
* Any observable latency degradation during Cato's backend updates.
