Most application security platforms are SaaS: you send your code, or your findings, to a vendor cloud. Self-hosted runs entirely inside your infrastructure. For regulated, sovereign or air-gapped environments, that difference is the whole decision.
With SaaS AppSec, your source code, findings or both are processed in a multi-tenant vendor cloud. With self-hosted, nothing leaves - the scanners, the correlation engine and the AI all run on your infrastructure. The strongest data-residency posture is not a region setting; it is sending nothing at all.
| Dimension | Self-hosted | SaaS |
|---|---|---|
| Where code is processed | Your infrastructure | Vendor cloud |
| Data residency | Met by design, no egress | Depends on vendor regions and sub-processors |
| Air-gapped support | Yes, fully offline | Rarely supported |
| AI analysis | Local model by default | Usually vendor cloud AI |
| Upgrades | You control the version | Vendor-controlled |
If you are a bank, a government body, a defence supplier or any team with data-residency or sovereignty requirements, self-hosted removes an entire class of vendor-risk questions from procurement. apPosture is self-hosted and air-gapped capable, with a local LLM by default and an external model strictly opt-in with a kill-switch. Deploy it in about 10 minutes.
It is a Docker Compose deployment. You trade a small amount of operational ownership for complete data control and no vendor egress.
Yes. apPosture runs a local LLM by default, so analysis happens without sending code anywhere. Any external model is opt-in with a kill-switch.
No. You receive releases and apply them on your schedule, which is often a requirement in regulated environments.
From discovery to a proven attack chain. A PoC in your own environment.
