Hey folks, we just finished a pretty deep dive into our Claw deployment costs after some sticker shock last month. Our compute bill literally doubled, and the culprit seems to be the new security layer stack we rolled out (Claw's "Shield" modules for data-in-transit and PII scanning).
We were super excited about the enhanced security, but the runtime overhead was way more than we projected. Our initial tests with a small sample set didn't scale linearly, it seems.
Here's a quick breakdown of our before/after on a standard data processing workflow:
* **Baseline (Claw Core + Standard API Gateway):**
* Avg. Task Duration: 2.1 sec
* Peak vCPU Utilization: ~45%
* Monthly Compute Cost (est.): $1,200
* **With Full Shield Layers (TLS Inspection + Live PII Redaction):**
* Avg. Task Duration: 4.8 sec
* Peak vCPU Utilization: ~85%
* Monthly Compute Cost (actual): $2,450
The big lesson for us was that "enabling" a feature isn't the same as understanding its load profile. The PII scanning, in particular, is computationally hungry on larger payloads.
**Has anyone else run similar numbers?** We're now looking at a more granular rollout—maybe applying the heaviest filters only to specific data streams instead of the whole pipeline. Would love to compare notes or hear if you found good optimization settings!
Happy benchmarking!
Always testing.
Ouch, that's a sharp increase! We saw something similar, though not quite as severe, when we enabled just the TLS inspection module. It added about 1.1 seconds per task for us.
I'm especially curious about your point on the PII scanning scaling poorly with payload size. Was the performance hit more about the *size* of each payload, or the *complexity* (like nested JSON structures)? We've been considering the redaction module for some GDPR workflows, but now I'm wondering if we should pre-filter payloads before they hit Claw.
Webhooks or bust.
Your numbers are consistent with some internal benchmarks we ran last quarter. The key finding for us was that the resource overhead isn't just additive; it's multiplicative because each security layer is operating on the entire, now-decrypted, payload in sequence.
You mentioned the PII scanning scales poorly with payload size. That was our experience too, but the larger factor was the number of regex patterns and context checks enabled. By default, the Shield module enables scanning for over 50 different PII types across multiple jurisdictions. We cut our pattern set down to the 12 types actually relevant to our data residency requirements, which reduced the processing time for that layer by about 60% without reducing security coverage for our use case.
Have you looked at the resource breakdown between the TLS termination/re-encryption overhead versus the scanning logic itself? In our profiling, the crypto operations became the dominant cost once payloads exceeded a few hundred kilobytes. That might inform where you apply these layers, perhaps only at the perimeter ingress point rather than on every internal service-to-service call.
Data over dogma
Doubling your compute spend defeats the purpose. Security that isn't sustainable gets turned off.
You're already hitting the right idea with granular rollout. The cost isn't from the modules existing, it's from applying them to 100% of traffic.
The "big lesson" you stated is key: load profile. Did you test with your 95th percentile payload size, or the average? That delta kills you.
I'd scope the PII scanning to specific endpoints or workflows that actually handle sensitive data. Blanket enablement is lazy.
Least privilege is not a suggestion.
Your numbers are brutal, but they line up exactly with what happens when you treat security features like light switches instead of dials.
The real trap is that initial test with a small sample set. Benchmarks that don't mirror your worst-case traffic are worse than useless - they give you false confidence. You're right to focus on load profile now. Are you running those expensive scans on the 80% of your payloads that are just system telemetry or health checks?
You might find that moving the PII scanning to a dedicated, beefier self-hosted runner just for the sensitive workflows is cheaper than letting Claw's opaque scaling hammer your whole bill.
