Comparisons / Cloud posture (CSPM)
RowShield vs Wiz: Supabase monitoring vs agentless cloud posture
The short version
- Wiz is an agentless cloud security platform that scans entire AWS, Azure and GCP estates and correlates exposures, identities and workloads into attack paths. RowShield is a continuous monitor built for one subject: the Supabase backend — its row level security, its REST surface, its storage rules, and how they change over time.
- Choose Wiz when — you run many cloud accounts, staff a platform or security engineering team, and need estate-wide posture, compliance mapping and attack-path analysis in one console.
- Choose RowShield when — your critical data lives in one or a few Supabase projects, nobody on the team owns a CNAPP queue, and you want policy drift reported as remediation SQL within minutes of a change.
RowShield rules relevant here
Head to head: Wiz vs RowShield
| Capability | Wiz | RowShield | Edge |
|---|---|---|---|
| Coverage scope | Sweeps whole multi-cloud estates: virtual machines, containers, identities, networks and code across providers. | One Supabase project end to end: database, auth surface, storage buckets, REST behaviour and keys. | Wiz |
| Visibility inside the Supabase data layer | Supabase appears only as far as it leaves traces in your account — peering, endpoints, allowlists. The Postgres inside it is out of view. | Native. Tables, pg_policies contents, role grants, bucket settings and deployed client bundles are inspected directly. | RowShield |
| RLS semantics | Not modelled. There is no concept of a policy whose USING clause is always true or an UPDATE policy without WITH CHECK. | Core checks: tautological policies, missing WITH CHECK clauses, RLS disabled in public, tables with no policies at all. | RowShield |
| Live behaviour as the anon caller | Configuration is inspected; requests are not issued against your API surface. | The probe calls PostgREST with the public anon key — GET only — and reports which tables actually return rows. | RowShield |
| Drift between checks | Findings reflect the latest scan of the estate; there is no baseline of your Supabase policy set to diff against. | Catalog snapshots are diffed every scan; each finding is classified created, resolved or regressed. | RowShield |
| Remediation output | Rich graph context and tickets aimed at infrastructure teams. | Copy-ready ALTER and CREATE POLICY statements generated from your actual columns and roles. | RowShield |
| Compliance frameworks and integrations | Extensive framework mapping, SIEM/SOAR integrations and enterprise workflows. | Slack, Discord, email and webhooks, with severity thresholds. Framework paperwork is not the product. | Wiz |
| Buying fit for a small team | Enterprise agreements sized for organisations running large estates. | Free audit, low monthly plans, no procurement cycle. | Wiz |

What Wiz does
Wiz, Inc. is widely credited with defining the agentless CNAPP category, and respect is due: its approach is genuinely strong. It connects read-only to your cloud accounts, examines workloads through provider APIs rather than deployed agents, and folds everything into a security graph. From that graph it derives attack paths — a public exposure chained to an over-permissioned identity and a valuable data store — and reports them alongside vulnerability, identity and configuration findings.
The console is built for cloud platform and security engineering groups who own dozens or hundreds of accounts, and it maps findings onto compliance frameworks and team queues. For that mandate it is an excellent instrument. Nothing in that mandate, however, requires knowing what a row level security policy does.
Where the scopes differ
Wiz analyses cloud resources. A Supabase project is a managed service: its Postgres instance, auth server, storage layer and REST gateway run on infrastructure belonging to Supabase, not enumerated as resources in your account. Wiz sees the shadow the project casts — a peering connection, an IP allowlist entry — and reports on that.
Run the three-capability lens and the boundary is precise. Policy posture: Wiz does not read pg_policies, so a policy whose condition is always true, or an INSERT policy with no WITH CHECK, produces no signal. Behaviour: Wiz never issues a request as your anon caller, so it cannot observe that a table actually returns rows to the internet. Drift: there is no baseline of your policy set to diff, so a quiet March migration that loosens a policy generates nothing.
In fairness, Wiz will honestly tell you when a database endpoint is reachable from the internet, which is a real and useful class of finding. It simply stops at the network boundary, while every question that decides whether tenant data leaks lives past it.
Why Supabase teams choose RowShield over Wiz
Because the searcher who lands here usually has one backend and no cloud estate. Is RLS enabled on every table in the public schema? Can the anon role fetch rows the UI never shows? Did last night’s AI-generated migration revert the fix from February? These are RowShield’s unit of work: scheduled scans over nine shipped rules, catalog snapshots diffed for created, resolved and regressed findings, a probe that exercises the REST surface exactly as a visitor would, and remediation SQL generated from your own column names.
There is also fit. A five-person company with two Supabase projects does not have an estate problem; it has a data-layer problem. Buying an enterprise CNAPP for it delivers weeks of rollout, a queue tuned for infrastructure engineers, and a contract sized for a different buyer — while the specific artefacts that leak Supabase data go unexamined.
Where Wiz is the right choice
If you operate a genuine multi-cloud estate, carry ISO 27001 or PCI obligations across many accounts, and employ engineers whose job is to work findings, evaluate Wiz seriously — its graph reasoning and agentless reach are ahead of most rivals and we will not pretend otherwise. Choose it for that job. Just be precise about the boundary: reachability findings stop at the network edge, so even teams who rightly buy Wiz for the estate add RowShield for the backend, where the policy logic lives.
Using both
The pairing is common and needs no ceremony. Wiz keeps custody of the estate: account posture, attack paths, framework reporting. RowShield keeps custody of the backend: continuous semantic watch on policies, roles, buckets and keys, with transition-only alerts into Slack or email minutes after a change. Give each tool one sentence of ownership so findings land in the right queue, review both in the same weekly slot, and neither duplicates the other because they barely overlap in subject matter.
Frequently asked
- Is RowShield affiliated with Wiz?
- No. RowShield is developed by Veristria, an independent company, and is neither endorsed by nor affiliated with Wiz, Inc. Wiz is a trademark of Wiz, Inc.; it is named here descriptively, based on publicly available documentation reviewed on 2026-08-23.
- Is RowShield a good Wiz alternative?
- For the estate-wide job, no — nothing here replaces multi-cloud posture management, and we say so. As a Wiz alternative for Supabase specifically, yes: when your infrastructure is a few managed services and your main risk sits in the backend, RowShield covers precisely the layer Wiz cannot see, and the two coexist comfortably when you need both.
- Does Wiz detect a misconfigured RLS policy on Supabase?
- Not as a rule. Its agentless connectors can flag that a database endpoint is publicly reachable, which is useful, but row level security logic inside Postgres is not modelled in the security graph. Over-broad USING clauses and missing WITH CHECK clauses fall outside its scope — the gap RowShield fills continuously.
